Julian Ilett Indeed. In fact the new postal uniforms should be red with white fur trims. Sometimes I wonder why the China stuff comes through as big clumps of packets though.
bigclivedotcom LOL my postman is a woman. Not sure if I should suggest it. Well, she is a lovely and friendly lady. Not sure what she thinks about me with all these envelopes from China and HK.
These Chiwanese tronics devices are great fun. The unassembled kits are just dollars and should be easily assembled. // I got the clear and translucent blue non-Dinky versions of the USB tester/VA meter for 2.13USD and 1.60USD, and they're very handy for troubleshooting chargers and cables, etc. // What a LOVELY water feature, Julian. // I still cringe when I see you hacking things open with that box knife. I use the little enclosed envelope slitters I got free from 37 places at COMDEX (back in 1998) and other trade shows. Checking Ebay, they're $4USD now! Ridiculous.
The component tester was the last item I ordered before abandoning my electronic projects hobby in favor of traveling. I have been on the road now for about a month now, and I do miss my electronics. I brought along some of my home built toys, and some of my power supplies, as well as my huge LED setups that I have mounted on old PIII heatsinks. I have multi-color 50 watt and 100 watt LEDS most of them are trash but some of the color ones do perform, especially the blue red and green ones, they all seem real and quality LEDS most of the white are really bad. I planned on hooking them up and shining them on the awning on my 35 foot Class A motor home down here in Arizona, but life keeps getting i the way, and I have yet to even unpack them. Oh well I can still keep up on what is going on in the electronic world through your posts. I brought along several arduino's and my little Raspberry Pi with a 7 inch screen for it, but again have yet to even find those in my many boxes of toys. Anyhow if you were here in the States, I would wish you a Happy Thanksgiving as today is it. We have few plans other then attending the campground thanksgiving turkey dinner given by the owners and staff of the small campground we are spending the winter months at here in Arizona, some 1300 miles from our home in Lemmon SD.
I have had a few of these in different shapes and sizes. The Zif connector is the problem for me as I test used transistors, TIP35C, etc. Can't get them in the Zif connector. Cant get lots into that connector once used as solder still on leads or the leads cut. So I bought one with leads to get around that problem and now getting rid of others as I do not use them. FYI, Do not keep in close proximity to active Tesla coil or high powered Slayer Exciter. The two meters I did experiments with close to coils just ask to be calibrated now. Maybe unrelated but high coincidence. Be Happy.
I ❤ my tester because it made building the other 8 kits on my bench so much faster. It would have been great if it did nanofared capacitors. That would have saved me getting out my bright light and magnifying headset to attempt to read the silly things. But not having to read the color stripes on quarter watt resisters made up for that somewhat. 😁 Seriously, nifty tool.
It's a shame that they didn't use different colour LED modules on the charger doctor. I'm sure that you could use the water pump in a copy of the famous sculpture in Brussels, The Manneken Pis.....
Hi Julian, I ordered the transistor tester. It stopped working for me. It boots if I raise the voltage to 10.8v. Instead of measuring, the device turns off. Any ideas on how to fix it? Before this the LCD would be flickering.
I like and must have that Component tester. What I find strange is that they all seem to work on a 9V batt as if they were going to be used in a handheld meter somehow. Would be nice to put a dc/dc in front of it to make the universal meter more universal. Now I need to find a link to that oled usb doctor. Being 2 weeks in the sun doesn't help out.
Ok, found .. and ordered ... that Oled usb doctor. Julian, they should sponsor you. I think you should get loads of free stuff since we buy it when we see it.
Luc Peeters Yeah, me too. I first saw the simple USB charger doctor in his videos and while ordering also found the OLED one, which I ordered. A week later Julian made a video about it while mine was already in the mail (still waiting on it). Weirdly it has been several times now that I ordered stuff just to have it appear shortly after that in his videos. But it has been the other way round, too. Seen stuff in his video and then ordered it. The only problem with sponsoring: most of the stuff is so cheap (which I like), that it's almost not worth the time to ask for it for free.
superdau I know I know, but add all those things up that you collected after 6 years that I've been ordering from China and you get a nice amount of money (and space). We have an awful hobby, all of us here ;-) . More, better, compare, newer .. all motivation to buy stuff. I am cleaning my fathers room(s) up after his 50 year of purchasing electronics stuff and working in the electronics industry. I for sure do not want leave this behind for my son or wife. Well I do not smoke nor drink, that's what I keep telling my wife, but now I see Julian with quadcopters and I think another lost soul because I also have a couple of them. We are all the same suckers it seems LOL
Hi Julian. When you've a mo, could you please put a few turns around the green ferrite ring and measure the inductance on your tester. I'd be interested to know the inductance / turn. I've got a ring on order from China for a ferrite ring 50mm x 30mm x 19mm and i'm hoping to get a few mH from 40T or so. Am I likely to be disappointed! Thanks
Documentation about this class of testers can be found at www.avrtester.tode.cz/upload/ttester_en.pdf Very interesting devices, history and, of course, cloning by the Chinese... I would be interested to know if anyone has had success with other software in the particular version that Julian has here, the one modified by Fish8840. Note that according to the documentation, the security bits are set on the original software in this version so there is no way to restore it to the original state if something goes wrong.
Julian Ilett Do you have a list of your charger doctors anywhere? I assume you have seen most models by now, and it would be really nice to see them accumulated in a review.
Another great video Julian =) I've ordered a basic charger doctor myself given it was cheap as chips, plus one of those cheap Arduino Nano boards from your other video. You're a bad influence! Keep it up ;-)
Hi, I bought the same one, is there some tutorial to update or change the program? The transformer logo is bugging me and I would like to remove that part from the code.
Hi i was just wondering if there is any way I could make a device that is battery powered that sends electronic pulses through a wire, but I would like to be able to change the pulses is this possible by any chance? thanks
Hi Julien don't know if you've been asked before or if you have mentioned it before, where did you get your work mat with the grid etc on it is it ESD protective with a bond and strap connector cheers Sean
If you search ebay or amazon for "cutting mat" you would find such an item, some offer "self healing" properties and so but looking at the logo on his .. Amtech came up amtechdiy.com/product/s0540-a4-cutting-mat/ Nothing special about it regarding ESD and so on far as I can see.. I got a slightly larger one from ebay recently, cheap enough not to worry when a wayward soldering accident sets it on fire or so :)
I actually build one of those component testers last month. Though it didn't have a display as nice as yours (just a 16x2). Originally developed by some German guy. The Chinese have since been making these. I'm probably a bigger cheapskate than you, since I build mine myself to save some money (-; Would be fun to see if it measure that huge inductor you're going to build.
Julian Ilett if you finished with winding then please share some knowledge about your step up/down converter with the coil. I would love to build an arduino step don :-)

Hi Can you help me to calculate inductor number of wires, size etc for 50amp mppt. Currently I am using T157-26 x 2 Yellow White cores 12 rounds of 22 gauge wire 20 wires together like a rope? Problem is it is core size is small and winding (rounding) 20 wires is really difficult.
After I saw this, I bought one of the component testers shown in the vid. Question; I have looked for software that you could run on a laptop. Input via USB attached to a proto board. Any ideas?
You should check out this USB Charger doctor, it displays Volts and Amps. You can also get a model that has a blue LED block for the amps which makes it easy to see which is which at a glance. www.ebay.ca/itm/171349112644 I forgot to mention that this bad boy has two USB outputs, the first one allowing for charging and data transfer while the other only allows for charging.

Beautiful water feature haha. fwiw kitsandparts.com sell USA made iron cores for comparable prices to ebay. Postage might be a bit to the UK, but if you ever need to buy a bunch of them...
You can buy all that stuff for very much less, purchasing them directly on Aliexpress. I've bought tons of crap from that site and became addicted. So much crap to buy.
I think the postmen are used to delivering the big bundles of Chinese tat held together in clumps with red rubber bands. It's like Xmas every week.
It is like Xmas every week. Better in fact, because I get stuff I actually want.
Julian Ilett Indeed. In fact the new postal uniforms should be red with white fur trims. Sometimes I wonder why the China stuff comes through as big clumps of packets though.

love that Component Tester, I want one !!!!

The bottom segment of that charger thing was actually working but it was extremely extremely dim

I purchased the component tester. Thank you! Your videos are so entertaining.
They are handy,I got four different one ,one was a kit ,one was a commercial one ,they are not real exspensive and are very handy.
You do not need full GREEN ferrite, it is for low frequencies.
You need YELLOW/WHITE; GREEN/BLUE; RED/BLACK
Loved the component tester, ordered one... wonder how long till it turns up though...
It's a shame that they didn't use different colour LED modules on the charger doctor.
I'm sure that you could use the water pump in a copy of the famous sculpture in Brussels, The Manneken Pis.....
Have you found the 12864 LCD Transistor Tester Capacitance ESR Meter Diode Triode MOS LCR NPN tester useful since you bought it?
Hi Julian, I ordered the transistor tester. It stopped working for me. It boots if I raise the voltage to 10.8v. Instead of measuring, the device turns off. Any ideas on how to fix it? Before this the LCD would be flickering.
I bought the pump for AUS $1 the other day, haven't tested it yet.

+Julian Ilett can you explane me why blue leds are harder to test? thanks!
How about water-cooling solar panels for efficiency?
Given water isn't too expensive.
POWER ! Lord with two rings ! hahaha.... you better don't hide and seek, we need you for mail bag time and cheapie parts reviews.
I got 1 of those component testers. Do you have a link on where to insert the components. Needless to say it came without literature :)
there are numbers above the ZIF socket 12331111

Can you do a video on the water feature when you have built it
Julian Ilett Do you have a list of your charger doctors anywhere? I assume you have seen most models by now, and it would be really nice to see them accumulated in a review.
I've put links in the description now.
Nice idea

Good idea. When I've wound the inductor, I'll put it on the tester and compare it with the smaller one.

Ie: software that replicates the fish8840?
Thanks for the vid but non e of your links work to ebay
DUDE I HAVE 3 4 - 5 INCH WIRE COILS HERE AT HOME.( SORRY ABOUT THE CAPS)
These bits take an age to arrive - so it's always nice to get a big clump of those silver plastic bags from China all at once.
how do you do caps on the tester?
Did you tell your wife you ordered some rings? :}

Very well done. THANKS!! I buy a lot of this cheap stuff. Now I may buy more.
they gonna have to build a new post office if u continue like this :D
I'm from the "future"... TIP: In 2018, these will work even better. You're welcome :)
