Many many moons ago, I believe it was 1971 because I had just returned from Vietnam, and had reported in to my new Army post at Fort Lewis Washington. I sold the old 58 Buick that I drove out to Washington from South Dakota, and purchased a used 67 Ford 2 door sport coupe. It had an aftermarket reverb unit that ran between the front and rear speakers, I thought it was the best deal I had ever seen. I had purchased a cassette player for the car while in Nam through the PACEX catalog and mounted that in the car as well, but I just could not get over the sound of Crimson and Clover plain on that reverb through the duel speaker system, man that was mind blowing!
Julian, if Windows 10 Updates are causing you a headache: 1) System Restore to the last good version of Windows 10 (that doesn't break your machine) 2) On restart, open Task Manager (Ctrl-Shift-Esc works on most computers) and go to the services tab 3) Look for a service called "wuauserv" (at the bottom of the list when set to alphabetical order) - this is the Windows Update service. Right click and stop service. 4) From Start search, type "services.msc" and press enter. (There may also be a way of reaching this via the task manager.) This brings up the services panel. 5) Make sure that the extended option is chosen, rather than standard (two tabs at the bottom) - then, in alphabetical order, find wuauserv again. (It appears under the name of Windows Update.) Right click and choose properties. 6) Set startup type to "Disabled" , click apply then ok. Then exit the services panel. This should switch off the Windows Update service and will stop Windows from searching for updates (including the update that seems to be taking out your machine). So long as you don't have anything else set to search for Windows Updates (like McAfee does, in default mode) then you should never be bothered by updated again.
Looking forward to more PIC tutorials and e-ink experiments! I would recommend to show all those blinking LED examples, you'll be able to teach a lot of microcontroller basics with a single example!
wow! what a great video. lady in sunglasses, jaundice Medusa, Julian in a cave with echo and then the finger on the chip diversion, Alice in hat... what's not to like! a truly unique channel!
Everyone is talking about windows and linux, but it just took me 2 minutes to watch this long video so might have missed to point my slider at that point. Its rather interesting to scroll the eyes on viewers comments than to gaze on those power supplies without any performance testing.
Well my good wife of 49 years now has that computer, and loves it, I picked up a used DELL at a hock shop in Kingman Az last winter, and it came with 10. It seems they have fixed some of the bugs, at a high cost of speed for a little bit of reliability. I was looking for an OS for my PINE64 computer when I came across Peachpi OSI. It looked so good, I had to download her, and now have it running as my primary OS with Windows 10 as a boot if I absolutly must have Windows running for some strange reason. Peachpi is a Ubuntu spin off with an eye to emulating a bit of OS X I guess judging by the desktop but is really all just Ubuntu under the skin, and runs very smoothly. I do have a new love in the Linux world.
Julian, I heartily recommend getting an SSD for your computer - the difference is day and night. I can reboot with updates in less time than it takes to make a cup of tea. At least for your OS partition, they're so, so cheap now.
On topic of not knowing what's in the box or where you got it: When I order from eBay, which seems to be multiple times a day, I copy and paste the Order number into the "Address Second Line" ( In Checkout ) Then I don't have to guess where I got it. Works for me and has been for over a year. Try it....
Hey Julian. That noise you are hearing is actually your own personal frequency amplified through the speaker you are hearing. You must have touched a connection that is connected to the line in and fed in the small voltage that your body produces. I have actually played around with this effect after once accidentally touching the end of a 3.5mm jack on a powered speaker. You just need your speaker there with a double ended 3.5 mm jack connection and your speaker on if you lay your finger along the length of the end not connected and maybe have to move it around you will hear a strange buzzing coming out of there. also another thing I have tried is randomly probing my skin with a digital multimeter set to the DC volts setting . having the probes about 1 to 2 cm apart I have picked up voltages of 0.020 V to .150 V sustained. if the muscle underneath is activated then you get a higher reading.
What I really want is a large color eInk display (like poster sized). I've looked and looked, and I've even found ones whose display is set at the factory and apparently can't be changed, but haven't found one you can change. I don't care if it has a refresh rate measured in multiple seconds for my purposes, but I do want it able to be changed.
The switch-mode IC for the negative rail will probably have the entire difference between the positive input rail and negative output rail across it, so may need a higher voltage rating for that reason.

You didn't get back to determine if the audio echo board used bi-polar supply rails or single ended positive rail with DC offset bias instead? Do follow up on next update of it's project. Thanks

You should look in to bucket brigade delays. They sound great, and the whole concept behind them is kind of ridiculous, but awesome. (The new DOD rubberneck uses them)
I am really interested in knowing more on the e-ink module. It is quite pricey for such a small display though, compared to the 6 and 8 inch replacement screens you can buy, the shield doesn't seem too complicated from what i can see here.
How exciting. The components on that board doesn't seem to warrant the high price vs. a large e-ink screen, do they? I just found this essentialscrap.com/eink/
Hey Julian, I really appriciate your Videos and your effort! I have a small PV related question, I hope you (or anyone else) can answer it for me: If a Solar panel doesn't get maximum light, is the Voc still the same as with more light (Of course only to a cerain point)? And does partial light at the morning/evening only change the output of current? I really didn't find a good answer anywhere :/ Thanks anyway! Cheers!
You select one timer (timer0 as 16 bit) as a free running timer with low priority OF interrupt. On the over flow, you increment an unsigned integer volatile global variable. Now you have the making of all sorts of timings, from anywhere in your code. Just add the function call (none recursive) code, into the interrupt service routine. No silly delay(), accurate to a few clock cycles and variables can be created for diffent jobs and put in the timer interrupt section to be incremented. Usefull for many things in a state machine. Here is a sample of mine from 12 years ago written in Hitech C (Note: its the low priority section. the high priority section was used for timer 1&3 in a servo controller that could not be bothered with unimportant timing stuff, like LEDs and Tx/Rx stuff at 115200 bps): // ******************************* void interrupt low_priority LOW_ISR(void){ unsigned char TempChar; if ((RCIF) && (RCIE)){ TempChar = RCREG; if (OERR == 0){ } else ResetAll(); //This function can not be used outside of the service routine. } if ((TMR0IE)&&(TMR0IF)){ SomeGlobalVariable+= 1; //Time to move to the next overflow TMR0IF = FALSE; TimeOut++; if (TimeOutTimer) //Time to turn LED off? if (TimeOut > TIMEOUTLIMIT) Error(); //and blah blah code from here on } if ((TXIF)&&(TXIE)){ if (DelayCounter == TIMEOUT){ TXIE = FALSE; TXEN = OFF; DelayCounter = 0; } ++DelayCounter; if (TRMT == 0) TXREG = LedValue; } }
I need a similar power supply for a homebrew synth project, and I can't seem to find one on eBay that will give me all three outputs, +12, -12, and +5v. The link you have in the description isn't an active auction anymore. Do you know of another source?
Just a tip for Windows 10, a solid state hard drive is a MUST. I run an Intel i5 with a modern SSD and windows updates are virtually transparent, I only see the update screen maybe a few seconds each time on shutdown and reboot.
It isn't at work we just have normal 500 GB WD HDDs and big updates just take 15 minutes at max. It's trying to install the latest Windows 10 built and crashes. I suppose he should do a full reset or even check the hardware.
It's kind-of sad there are not more e-ink options out there. It would be a great technology for many small projects where low power is desired. It seems 98% of the effort has gone into creating e-reader displays. I did see where someone had decoded how to drive kindle displays. The screen is a bit bigger than you might want though.
GP2 can be driven by the comparator output, would need a fly lead to get GP2 to LED2 on jumper above. talking of fly... that cutting board is well fly... space fly indeed!
the windows 10 update issue: make sure the primary partition (which is most likely only 100MB) must be around 1GB to be safe!, there are several ways of increasing it without losing data, if you need help just contact me! i had exactly the same issue ;)
That Windows 10 update: try disconnecting all of your USB devices during the update process. For me it was a webcam built in to one of my monitors. Once I disconnected it the update went fine.
Julian, When you say your PC locks up, do you mean it sits at a black screen with the circular spinning dots? If so... try unplugging anything your have into the USB ports - particularly if you have a Logitech keyboard or mouse. There was an update back around Nov which locked a friends computer up, and it got stuck like that. Simply re-locating the logitech receiver to a different USB port fixed the issue... for some reason it got stuck until the drivers were re-initialised on a different USB port. It became a major issue like in your case as the update kept re-installing every couple of weeks until I got a chance to look at it.
That's exactly it - black screen, spinning dots and yes, I have the Logitech unifying receiver. If this fixes the problem, you're a genius (well, you're probably a genius anyway). Thanks Peter :)
It's worth a try... that was the same receiver that was having issues in this case. Strangely it didn't affect my own laptop, but perhaps it was a 32bit issue and not a 64bit one. Fingers crossed ;) That update gremlin isn't pleasant... it's like a ticking time-bomb because it keeps coming back :(
Woohoo! One problem fixed anyway... you just have to look forward to a few more updates whilst Windows catches up on what it missed in the meantime! :-O Glad it's working for you now though :D
great postbag Julian, how do you like to Sony tablet? I have used Sony for years, had my Sony z2 phone for 3 years or so and it's been faultless and worked hard every day
I love android systems. I literally have an android box that I use as a little computer and I mainly use it for kodi. If you don't mind using that sony tablet and I do believe it is possible to turn any desktop into an android computer. phandroid.com/2016/07/19/how-to-turn-your-pc-into-an-android-computer. This is supposed to be an alternative to a chromebook.
not as of yet. I have wimped out and just bought an android box because the equipment that I planned to use it on crapped out on me and it wasn't worth fixing.
Regarding how robust those displays are, I was given a Kindle some years back. i declined the stupid terms that Amazon was trying to force on me, and loaded it up myself, rather than going through their servers. At some point *something* (I can't remember what) impacted the screen, and it now looks totally awful, I don't use it at all any more since I got a tablet, and it's living in my bottom desk drawer.
Hahaha, Julian, everytime you rave over your solar set-up I can't help but think that you struck a deal with the missus whereby you're only allowed to keep your electronics man-cave if you power it yourself!
First are you using a wifi connection. I have only been able to use the metered connection trick on wifi. First go to your network icon in the bottom right hand side of the screen (the one with the dot and 3 semicircualr lines). Click on your connection. click on properties (a settings window should pop up) There is a section marked metered connection. make sure that slider is turned on. That should disable windows from doing updates You need to do a registry hack if you need to use it on an ethernet connection.
We need to change the tolerance band of your resistor torch ... The Pic tutorial wirh the led would be easier for beginners if you choose the on-delay-off-delay version ...
At 4:46 you adjust to MINUS 12v but what on your meter denotes a negative voltage? I may be well off here but your plus and minus readings look the same, neither have a 'minus' sign in front of them.
I'm looking forward to the vocoder project finished and hearing it. About Windows, yeah, that is why I got rid of it and went Linux (Linux Mint), to do update: sudo apt-get update && sudo apt-get upgrade That's it with no lockups and no multi-boots. With Windows, have to reboot for more updates, then once done, updates only breaks what was working before, but not now.
Regarding flashing a LED I think you should at first show it with on/delay/off/delay, because this is how you'd think in first. After that you might add xor/delay as an upgrade. After that you could show the timer solution without using interrupts. And maybe use the interrupt only when you actually want to explain interrupts in general and not to show that you can flash the LED. Maybe also mention the watch dog together with the timer interrupt, although I think that the watch dog isn't related to flashing an LED. In the end if you use the watch dog like a timer it is no different and doesn't explain the reason for a watch dog. Because to be honest to have a good tutorial it shouldn't boast about how awesome you are to devise so many ways to flash the LED, but it should actually explain what flashing an LED actually requires (like powering a pin, timing things on a microcontroller).
Anxiety? Bwaaa ;( Hey, Jules, I thought of you yesterday :D I've been dabbling with Arduino these past few days, and I got a "Does not name a type" error :P Turned out it was because I used the servo() object outside of a void segment. I put it in void setup() and that worked :D
Julian Ilett If you want a really wild several hours spread across two days, use an arduino micro to flash a bootloader to a blank atmega328 :P I'd love to see more 'duino stuff, plus if you do end up building stuff I can help you out with what _I've_ learnt :D
I sometimes forget there are still people using Windows. On an unrelated note, I've always wondered what happens when you pass a magnet over an E-Ink display, though I could be mistaken in thinking it uses magnetic fields to flip the little beads that make up the black/white pixels.
I'm no expert on the subject, but IIRC, e-ink displays use an electric charge on the pigments, not magnetic, so my guess is that a magnet probably wouldn't do anything. I'd still be interested in seeing someone try it though.
@AwesomeMcTasty I have a eBook reader (Kobo Glo) with eink screen, so tried wiping a reasonably strong neodymium magnet across some text with the unit powered down, and nothing changed on the display, so definitely doesn't appear to respond to magnetic fields.
E-ink display is becoming a niche product as they are not popular as far as display tech go. So it will forever be niche and expensive. If it were to come down in price, it would have done so already. Love your videos, Cheers
I'm gonna jump in with all the others chiming in and say give Linux a try. I know you want something that "just works" and don't wanna have to mess with it, but it's pretty clear that Windows 10 does not just work! Lots of people are having similar problems, along with all the privacy invasion issues. Microsoft really screwed the pooch on this one and it would be great if they could be scared back into shape by making a noticeable drop in adoption rate. Last time I checked, less than 25% of people were using Windows 10, well over a year after it came out and MS tried to force it on people that don't want it (they even made it so the close button on the obnoxious "upgrade to Windows 10 now!" popup scheduled it to install instead of canceling, then undid it after thousands of people complained), and tried to scare everyone else into doing it, and even giving it away for free. Not very many people like it because it's so riddle with problems and nasty tricks to take away the users choices... Maybe even a Mac would be a better choice, but the best thing about Linux is that it is free (gratis, some are also libre) so if you decide you don't like it, you didn't waste hundreds of dollars (or thousands on a Mac). There's a bit of a reputation that Linux is hard, but really it's only as hard as you make it, and a lot of the people complaining are only upset because they're used to doing things the Windows way, so that anything that is different seems hard, even when it's not. There are many distributions to choose from, but my guess is that Mint would be good for you, as it's simple, quick, and should still be vaguely familiar to Windows users.
Silly question time and you may have answered it previously but why do you buy stuff from ebay US and not ebay UK. On stuff I've looked at the same chinese sellers are on various ebay sites. :) Great video as always though.
I do get this question a lot - but several reasons. Funding comes from Patreon in dollars, so I like to buy in dollars. eBay.com is less inclined to show my postcode. Some sellers put a bigger range of products on eBay.com
Sounds fair. I suppose also exchange rate can be better too. It doesnt matter to the chinese sellers as they ship worldwide, I just wish some US sellers would. There are quite a few items I've been interested in but the US sellers flat out refused to send to the UK even through ebay's global shipping program. Most time I send to my brother-in-law and he ships to me but I hate to bother him. Didnt know that about the postcode.
I wouldn't worry too much about your postcode - with a bit of Googling, lateral thinking and snippets of information over time, it's reasonably easy to work out anybody's address if you really want to (even easier if you fork over some £££s to 192.com). I'll be round in five minutes for a cuppa - get the kettle on! ;-)
Hi Julian (or anyone who can help) is there any possibility of pointing me in the correct direction on AliExpress to buy a negative / positive PSU similar to the one shown here - my Google Foo is lacking it would seem and the closest I can find it ~$70 which is a bit steep :)
Ello J plz can you help me i'am looking for wiring diagram rotating spherical led kit i have looked all over the place if you can help me i would be so great full .k
Treat yourself Julian get a decent microphone. Even a bodge simple Shure SM57 or 58 wouldn't break the bank and a used one will be as good as new, they are solid and almost unbreakable yet afford one a decent frequency response for vocals anyway. But of course then you are going to have to deal with an XLR and adapt for impedance. What is the front end expecting for a mic,.. balanced or not? Best regards Chris P.s.... been totally glued to your recent PIC series
If you WSL installed try..... sudo apt-get update sudo apt-get upgrade once update has finished reboot and see if that sorts out the problem or replace all of the programs that you use with the UBUNTU version and delete the windows version. you will need your password that you used to install WSL you might able to get the whole UBUNTU Desktop into your version of WSL.
Yeah and then discontinue the PIC tutorial because the IDE isn't available for Linux. Linux is a piece of shit. When I try to install it on my fairly recent setup, it just locks up with "Kernel Panic".
Kyôdai Ken you can use Code::Blocks and gcc-pic or gcc-avr and gdb-pic or gdb-avr and gnuutils and I think that has a programmer interface GUI but I think I have found the programmer package for Linux which is
I don't trust this amateur software, I woudn't touch that with a 10 foot stick. There's a reason why he uses the official IDEs for it. Don't even think of Wine, this is just a playground project. When there's an official IDE for linux, okay. There is one for Arduino, I guess. But Linux doesn't even work on my system. It doesn't detect my SSD, latest Ubuntu and crashes. Asus X99-E WS 32 GB DDR4-2133 reg ECC RAM Intel Xeon E5-1560v4 (6x 3.6 - 4 GHz, 12 threads) 4TB HGST HDD 7200 RPM 400 GB Intel 750 Series PCIe card NVMe SSD GeForce GTX Titan X (2014) Dell UltraSharp UP3216Q 4K ~100% AdobeRGB monitor via DisplayPort on the above named GPU 860 Watts PSU Not even Clonezilla works. I stick with my professional OS.
Depends on your country, UK is free for me, but $1.85 for a Canadian friend. Best advice is to search eBay with the part/product name and find one with free shipping for your area from another seller.
when windows 8 came out, I was working at a company that required us to use it.. 2 nights within a week, forced updates, stuck without a computer hoping no emergencies came up. OMG I can't use windows..
pacaur -Ss mplab aur/microchip-mplabx-bin 3.51-1 (46, 0.79) IDE for Microchip PIC and dsPIC development aur/piklab 0.16.2-3 (12, 0.00) IDE for applications based on Microchip PIC and dsPIC microcontrollers similar to the MPLAB environment I would suggest ARCH LINUX, it has a giant user repository (AUR) where you can find almost any piece of software youll ever need without fiddling in your repositorys. it has the best wiki i have ever seen. you will find all your avr arduino and pic suff - IDE and toolchain - in there. greetings !
Windows 10. Poor man. Great postbag video by the way, thumbs up! I'm doing ISR coding on various Atmel MCs right now. Fun indeed! :) Edit: I will stick to Windows 7 until hell freezes over!
Oh, go ahead Mate. Pop in a live distro and give it a go. You can do a lot with the GUI and there is a Linux version of the Arduino IDE which works quite well.
I'd like to see you try NixOS. Setup is kind of fiddly, but a running system is so smooth it's almost magic. Any update that breaks can be rolled back in 0 time and configuration is done with a JSON-like language. You don't need root to install things, you can do $ nix-env -i arduino even on a live CD!
That's really a thing from the past. If you trying to run a server or something sure you probably need the CLI but for general purpose usage you can get by with just the GUI. and you don't get the MS headache for free.
Many many moons ago, I believe it was 1971 because I had just returned from Vietnam, and had reported in to my new Army post at Fort Lewis Washington.

you put your finger across the out put of the preamp pin 1 perhaps you touched the second pin aswell ? pin 2 is your negative signal input
Congrats on hitting and speeding past 100k subs :) I'm looking forward to seeing the e-ink display in action :)
Thanks!
@@JulianIlett Was there any followup on the e-ink display? I can't find anything and I sure would love to see it.
I think you have the record for buying converters .

+Darrell Edwards Very neat, I like it. But then again, I quite like puzzling over what's in the box :)
Hey Julian, I actually prefer the tablet EBay listings, it seems a lot more readable and you can even do it on your workbench.
Julian, goto your network settings and set your network connection for the internet to metered mode. That'll stop the updates from downloading.
Hey Julian. That noise you are hearing is actually your own personal frequency amplified through the speaker you are hearing. You must have touched a connection that is connected to the line in and fed in the small voltage that your body produces. I have actually played around with this effect after once accidentally touching the end of a 3.5mm jack on a powered speaker. You just need your speaker there with a double ended 3.5 mm jack connection and your speaker on if you lay your finger along the length of the end not connected and maybe have to move it around you will hear a strange buzzing coming out of there.
also another thing I have tried is randomly probing my skin with a digital multimeter set to the DC volts setting . having the probes about 1 to 2 cm apart I have picked up voltages of 0.020 V to .150 V sustained. if the muscle underneath is activated then you get a higher reading.

You didn't get back to determine if the audio echo board used bi-polar supply rails or single ended positive rail with DC offset bias instead?

mark ward I wasn't the only one that thought than
I've no doubt some of his mannerisms are rubbing off on me - and vice versa :)
I thought that sounded familiar 😂
mark ward what's next? Will you be incorporating some AvE-isms next
I think in a few of my videos so far I've managed to channel various amounts of Julian, Big Clive, AvE and HPC :D
You should look in to bucket brigade delays. They sound great, and the whole concept behind them is kind of ridiculous, but awesome. (The new DOD rubberneck uses them)
I built one once - I think it used the MN3011.
I am really interested in knowing more on the e-ink module. It is quite pricey for such a small display though, compared to the 6 and 8 inch replacement screens you can buy, the shield doesn't seem too complicated from what i can see here.
I'll try to get it fired up as soon as possible :)
How exciting. The components on that board doesn't seem to warrant the high price vs. a large e-ink screen, do they? I just found this essentialscrap.com/eink/
Hey Julian, I really appriciate your Videos and your effort!
I have a small PV related question, I hope you (or anyone else) can answer it for me:
If a Solar panel doesn't get maximum light, is the Voc still the same as with more light (Of course only to a cerain point)? And does partial light at the morning/evening only change the output of current?
I really didn't find a good answer anywhere :/
Thanks anyway!
Cheers!
hi could you give the length of the pt2399 board please. I was wondering if it would fit into a eurorack synthesizer. thanks jon
You select one timer (timer0 as 16 bit) as a free running timer with low priority OF interrupt. On the over flow, you increment an unsigned integer volatile global variable. Now you have the making of all sorts of timings, from anywhere in your code. Just add the function call (none recursive) code, into the interrupt service routine. No silly delay(), accurate to a few clock cycles and variables can be created for diffent jobs and put in the timer interrupt section to be incremented. Usefull for many things in a state machine.
Here is a sample of mine from 12 years ago written in Hitech C (Note: its the low priority section. the high priority section was used for timer 1&3 in a servo controller that could not be bothered with unimportant timing stuff, like LEDs and Tx/Rx stuff at 115200 bps):
// *******************************
void interrupt low_priority LOW_ISR(void){
unsigned char TempChar;
if ((RCIF) && (RCIE)){
TempChar = RCREG;
if (OERR == 0){
}
else
ResetAll(); //This function can not be used outside of the service routine.
}
if ((TMR0IE)&&(TMR0IF)){
SomeGlobalVariable+= 1; //Time to move to the next overflow
TMR0IF = FALSE;
TimeOut++;
if (TimeOutTimer) //Time to turn LED off?
if (TimeOut > TIMEOUTLIMIT)
Error(); //and blah blah code from here on
}
if ((TXIF)&&(TXIE)){
if (DelayCounter == TIMEOUT){
TXIE = FALSE;
TXEN = OFF;
DelayCounter = 0;
}
++DelayCounter;
if (TRMT == 0)
TXREG = LedValue;
}
}
Any chance you could link to a PT2399 delay with the runaway feedback where it continues to build? Really like that effect
What is that little tab on the E ink display and I have seen your other screens with it as well. Can you remove it or would the screen fall apart?
TheDutyPaid do you mean the brown or the green thing?
The brown thing is the display connector and the green thing is a display protector foil
Congrats on the 100k now it's 500k
15:20 is that not from your PWM5 controllers? Sounds familiar to your AM radio noise test on a much older video of yours.
+Tera Volt Yes I think you're right. 122Hz and the controller would have been modulating to hold 13.5 volts. Mystery solved :)
Congrats on the 100k subscribers!
I need a similar power supply for a homebrew synth project, and I can't seem to find one on eBay that will give me all three outputs, +12, -12, and +5v. The link you have in the description isn't an active auction anymore. Do you know of another source?
Just a tip for Windows 10, a solid state hard drive is a MUST. I run an Intel i5 with a modern SSD and windows updates are virtually transparent, I only see the update screen maybe a few seconds each time on shutdown and reboot.
It isn't at work we just have normal 500 GB WD HDDs and big updates just take 15 minutes at max.
It's trying to install the latest Windows 10 built and crashes. I suppose he should do a full reset or even check the hardware.
I didn't see a "-" sign on your DMM--in many videos. Does it show the negative dash??
That buzzing on the echo module might be the pwm from your solar charger?
I think you're right :)
I bet you can still sing awesome!
Did you ever do anything with the E.Ink dispaly? Cant find a Video
keep up the post bag videos, love them! ! !
Can the Karaoke Reverberation Board be directly connected to a pc and act as a mic?
It's kind-of sad there are not more e-ink options out there. It would be a great technology for many small projects where low power is desired. It seems 98% of the effort has gone into creating e-reader displays.
I did see where someone had decoded how to drive kindle displays. The screen is a bit bigger than you might want though.
Looking forward to an E-Ink Video
GP2 can be driven by the comparator output, would need a fly lead to get GP2 to LED2 on jumper above. talking of fly... that cutting board is well fly... space fly indeed!
the windows 10 update issue: make sure the primary partition (which is most likely only 100MB) must be around 1GB to be safe!, there are several ways of increasing it without losing data, if you need help just contact me!
i had exactly the same issue ;)
That Windows 10 update: try disconnecting all of your USB devices during the update process. For me it was a webcam built in to one of my monitors. Once I disconnected it the update went fine.
Including my mouse?
I left my mouse and keyboard attached but got rid of everything else including hubs.
Transistors, MOSFETs for level-shifting maybe?
Julian, When you say your PC locks up, do you mean it sits at a black screen with the circular spinning dots? If so... try unplugging anything your have into the USB ports - particularly if you have a Logitech keyboard or mouse. There was an update back around Nov which locked a friends computer up, and it got stuck like that. Simply re-locating the logitech receiver to a different USB port fixed the issue... for some reason it got stuck until the drivers were re-initialised on a different USB port. It became a major issue like in your case as the update kept re-installing every couple of weeks until I got a chance to look at it.
That's exactly it - black screen, spinning dots and yes, I have the Logitech unifying receiver. If this fixes the problem, you're a genius (well, you're probably a genius anyway). Thanks Peter :)
It's worth a try... that was the same receiver that was having issues in this case. Strangely it didn't affect my own laptop, but perhaps it was a 32bit issue and not a 64bit one. Fingers crossed ;) That update gremlin isn't pleasant... it's like a ticking time-bomb because it keeps coming back :(
I'll be sure to let you know the outcome :)
Peter, you're a hero! My PC is now fully updated. You fixed it - thanks :)
Woohoo! One problem fixed anyway... you just have to look forward to a few more updates whilst Windows catches up on what it missed in the meantime! :-O Glad it's working for you now though :D
hi Julian, did ya get round to the e-ink thingy vid ?
It's the built in bagpipe effect!
great postbag Julian, how do you like to Sony tablet? I have used Sony for years, had my Sony z2 phone for 3 years or so and it's been faultless and worked hard every day
Sony tablet is ok - it's fast, but it has a lot of Sony clutter. I'd prefer a pure android device.
I love android systems. I literally have an android box that I use as a little computer and I mainly use it for kodi. If you don't mind using that sony tablet and I do believe it is possible to turn any desktop into an android computer. phandroid.com/2016/07/19/how-to-turn-your-pc-into-an-android-computer. This is supposed to be an alternative to a chromebook.
Sarah1390
I too like Android systems, I don't use my PC much at all now. have you tried this mod on a PC?
not as of yet. I have wimped out and just bought an android box because the equipment that I planned to use it on crapped out on me and it wasn't worth fixing.
Regarding how robust those displays are, I was given a Kindle some years back. i declined the stupid terms that Amazon was trying to force on me, and loaded it up myself, rather than going through their servers. At some point *something* (I can't remember what) impacted the screen, and it now looks totally awful, I don't use it at all any more since I got a tablet, and it's living in my bottom desk drawer.
What do you use negative voltage for?
Hahaha, Julian, everytime you rave over your solar set-up I can't help but think that you struck a deal with the missus whereby you're only allowed to keep your electronics man-cave if you power it yourself!
you can change your network settings to as metered connection so that it will not download and install updates with that connecting.
I like that idea, but can't find where to change it simply
First are you using a wifi connection. I have only been able to use the metered connection trick on wifi.
First go to your network icon in the bottom right hand side of the screen (the one with the dot and 3 semicircualr lines).
Click on your connection.
click on properties (a settings window should pop up)
There is a section marked metered connection. make sure that slider is turned on.
That should disable windows from doing updates
You need to do a registry hack if you need to use it on an ethernet connection.
We need to change the tolerance band of your resistor torch ...
The Pic tutorial wirh the led would be easier for beginners if you choose the on-delay-off-delay version ...
I'll certainly start with on-delay-off-delay
Julian Ilett Thanks :D But im still waiting for my Pic and PicKit from China :(
At 4:46 you adjust to MINUS 12v but what on your meter denotes a negative voltage? I may be well off here but your plus and minus readings look the same, neither have a 'minus' sign in front of them.
A 1.5V battery is also a -1.5V battery, just depends on your point of reference.
Depends which way around you connect the leads.
The E-Ink Shiled is a circuit breaker? (at 20:33) :)
I'm looking forward to the vocoder project finished and hearing it. About Windows, yeah, that is why I got rid of it and went Linux (Linux Mint), to do update: sudo apt-get update && sudo apt-get upgrade That's it with no lockups and no multi-boots. With Windows, have to reboot for more updates, then once done, updates only breaks what was working before, but not now.
Regarding flashing a LED I think you should at first show it with on/delay/off/delay, because this is how you'd think in first. After that you might add xor/delay as an upgrade. After that you could show the timer solution without using interrupts. And maybe use the interrupt only when you actually want to explain interrupts in general and not to show that you can flash the LED.
Maybe also mention the watch dog together with the timer interrupt, although I think that the watch dog isn't related to flashing an LED. In the end if you use the watch dog like a timer it is no different and doesn't explain the reason for a watch dog.
Because to be honest to have a good tutorial it shouldn't boast about how awesome you are to devise so many ways to flash the LED, but it should actually explain what flashing an LED actually requires (like powering a pin, timing things on a microcontroller).
Anxiety? Bwaaa ;(
Hey, Jules, I thought of you yesterday :D I've been dabbling with Arduino these past few days, and I got a "Does not name a type" error :P
Turned out it was because I used the servo() object outside of a void segment. I put it in void setup() and that worked :D
Haha, thanks. I'll be looking at Arduino again soon - probably trying to get the INA219 to work :)
Julian Ilett If you want a really wild several hours spread across two days, use an arduino micro to flash a bootloader to a blank atmega328 :P
I'd love to see more 'duino stuff, plus if you do end up building stuff I can help you out with what _I've_ learnt :D
Looking forward to cheaper e-paper solution!
I sometimes forget there are still people using Windows. On an unrelated note, I've always wondered what happens when you pass a magnet over an E-Ink display, though I could be mistaken in thinking it uses magnetic fields to flip the little beads that make up the black/white pixels.
I'm no expert on the subject, but IIRC, e-ink displays use an electric charge on the pigments, not magnetic, so my guess is that a magnet probably wouldn't do anything. I'd still be interested in seeing someone try it though.
@AwesomeMcTasty I have a eBook reader (Kobo Glo) with eink screen, so tried wiping a reasonably strong neodymium magnet across some text with the unit powered down, and nothing changed on the display, so definitely doesn't appear to respond to magnetic fields.
Why you use windows, do you really need it?
For MPLAB yes. But I'm seriously considering Chromebook
E-ink display is becoming a niche product as they are not popular as far as display tech go. So it will forever be niche and expensive. If it were to come down in price, it would have done so already.
Love your videos,
Cheers
I'm gonna jump in with all the others chiming in and say give Linux a try.
I know you want something that "just works" and don't wanna have to mess with it, but it's pretty clear that Windows 10 does not just work! Lots of people are having similar problems, along with all the privacy invasion issues. Microsoft really screwed the pooch on this one and it would be great if they could be scared back into shape by making a noticeable drop in adoption rate. Last time I checked, less than 25% of people were using Windows 10, well over a year after it came out and MS tried to force it on people that don't want it (they even made it so the close button on the obnoxious "upgrade to Windows 10 now!" popup scheduled it to install instead of canceling, then undid it after thousands of people complained), and tried to scare everyone else into doing it, and even giving it away for free. Not very many people like it because it's so riddle with problems and nasty tricks to take away the users choices...
Maybe even a Mac would be a better choice, but the best thing about Linux is that it is free (gratis, some are also libre) so if you decide you don't like it, you didn't waste hundreds of dollars (or thousands on a Mac). There's a bit of a reputation that Linux is hard, but really it's only as hard as you make it, and a lot of the people complaining are only upset because they're used to doing things the Windows way, so that anything that is different seems hard, even when it's not. There are many distributions to choose from, but my guess is that Mint would be good for you, as it's simple, quick, and should still be vaguely familiar to Windows users.
What are you using minus voltage for?
To see if the negative segment of the multi meter still works !
Op-amps I think.
You have the most DC-DC converters. =]
I like the tablet better than the pc for this type of thing. I think it is easier to read than camera-to-screen
In my mind the tablat is better to show the eBay descriptions. ^^
the noise when touching the opamp might be you acting as an antenna when touching the input pin.
Silly question time and you may have answered it previously but why do you buy stuff from ebay US and not ebay UK. On stuff I've looked at the same chinese sellers are on various ebay sites. :)
Great video as always though.
I do get this question a lot - but several reasons. Funding comes from Patreon in dollars, so I like to buy in dollars. eBay.com is less inclined to show my postcode. Some sellers put a bigger range of products on eBay.com
Sounds fair. I suppose also exchange rate can be better too. It doesnt matter to the chinese sellers as they ship worldwide, I just wish some US sellers would. There are quite a few items I've been interested in but the US sellers flat out refused to send to the UK even through ebay's global shipping program. Most time I send to my brother-in-law and he ships to me but I hate to bother him. Didnt know that about the postcode.
I wouldn't worry too much about your postcode - with a bit of Googling, lateral thinking and snippets of information over time, it's reasonably easy to work out anybody's address if you really want to (even easier if you fork over some £££s to 192.com).
I'll be round in five minutes for a cuppa - get the kettle on! ;-)
I know what you mean and BTW do you take milk & sugar. :)
Hi Julian (or anyone who can help) is there any possibility of pointing me in the correct direction on AliExpress to buy a negative / positive PSU similar to the one shown here - my Google Foo is lacking it would seem and the closest I can find it ~$70 which is a bit steep :)
Do you really make all your videos in the mornings? :)
I usually start in the morning :)
Good morning, Governor.
So this echo effect is digital.
Ello J plz can you help me i'am looking for wiring diagram rotating spherical led kit i have looked all over the place if you can help me i would be so great full .k
I assumed you were an Ubuntu man for sure. You should try it!
Treat yourself Julian get a decent microphone. Even a bodge simple Shure SM57 or 58 wouldn't break the bank and a used one will be as good as new, they are solid and almost unbreakable yet afford one a decent frequency response for vocals anyway. But of course then you are going to have to deal with an XLR and adapt for impedance. What is the front end expecting for a mic,.. balanced or not?
Best regards Chris
P.s.... been totally glued to your recent PIC series
nice PSU module.
If you WSL installed try.....
sudo apt-get update
sudo apt-get upgrade
once update has finished reboot and see if that sorts out the problem or replace all of the programs that you use with the UBUNTU version and delete the windows version. you will need your password that you used to install WSL you might able to get the whole UBUNTU Desktop into your version of WSL.
Yeah and then discontinue the PIC tutorial because the IDE isn't available for Linux.
Linux is a piece of shit. When I try to install it on my fairly recent setup, it just locks up with "Kernel Panic".
Kyôdai Ken you can use Code::Blocks and gcc-pic or gcc-avr and gdb-pic or gdb-avr and gnuutils and I think that has a programmer interface GUI but I think I have found the programmer package for Linux which is
I don't trust this amateur software, I woudn't touch that with a 10 foot stick.
There's a reason why he uses the official IDEs for it. Don't even think of Wine, this is just a playground project.
When there's an official IDE for linux, okay. There is one for Arduino, I guess.
But Linux doesn't even work on my system. It doesn't detect my SSD, latest Ubuntu and crashes.

Not even Clonezilla works.
I stick with my professional OS.
W10 update: are you out of disk space??
Why is Alice always free postage for you and always $1.85 when i look? Any ideas?
Depends on your country, UK is free for me, but $1.85 for a Canadian friend. Best advice is to search eBay with the part/product name and find one with free shipping for your area from another seller.
I looked in to eInk displays but they were just TOO expensive!
Yeah, that's what always put me off - waiting for the price to drop to that of OLEDs
For the same money you can get a cheap Ebook reader with a 5" display that you could maybe hack as a screen?
I've been looking into this and apparently the Nook Simple Touch is the most hackable e-reader out there.
when windows 8 came out, I was working at a company that required us to use it.. 2 nights within a week, forced updates, stuck without a computer hoping no emergencies came up. OMG I can't use windows..
Funnies - move the mike close to the speaker, and twiddle the reverb. :)
pacaur -Ss mplab
aur/microchip-mplabx-bin 3.51-1 (46, 0.79)
IDE for Microchip PIC and dsPIC development
aur/piklab 0.16.2-3 (12, 0.00)
IDE for applications based on Microchip PIC and dsPIC microcontrollers similar to the MPLAB environment
I would suggest ARCH LINUX, it has a giant user repository (AUR) where you can find almost any piece of software youll ever need without fiddling in your repositorys.
it has the best wiki i have ever seen.
you will find all your avr arduino and pic suff - IDE and toolchain - in there.
greetings !
well, very nice video, i think you can just disable their windows update service directly so the update service will not be running ;)
Does Spring Onion have a green card?
Windows 10. Poor man. Great postbag video by the way, thumbs up! I'm doing ISR coding on various Atmel MCs right now. Fun indeed! :)
Edit: I will stick to Windows 7 until hell freezes over!
How come your are not using Linux?
Because I have command line phobia ;)
Oh, go ahead Mate. Pop in a live distro and give it a go. You can do a lot with the GUI and there is a Linux version of the Arduino IDE which works quite well.
sudo Embrace your fears ;)
I'd like to see you try NixOS. Setup is kind of fiddly, but a running system is so smooth it's almost magic. Any update that breaks can be rolled back in 0 time and configuration is done with a JSON-like language. You don't need root to install things, you can do
$ nix-env -i arduino
even on a live CD!
That's really a thing from the past. If you trying to run a server or something sure you probably need the CLI but for general purpose usage you can get by with just the GUI.
and you don't get the MS headache for free.
Use Linux
10:25 reverberb?
hi why don't you upgrade to windows 7
playdav485 downgrade
that depends on your opinion of windows 10
I never moved from Win 7 and have no regrets.
Windows 8 is best!!
i tried windows 10 changed back to 7 within 2 weeks
The noise was coming from your Windows 10 update.... ;)
6:00 a genuine reason to stick with win7 - choose when you want to install updates; e.g. when you have finished your work and leave for home.
