I’d bet you’re using a phone charger for your Pi as well. But even though phone chargers are labeled as 2 amps, in the case of a Raspberry Pi-or, for example, with a connection where the data pins are missing (only VCC and GND are present), like in the video where it was connected to the hub-they only deliver a maximum of 500 milliamps. They provide 2 amps only if the appropriate resistors are detected on the data pins by the charger, or with newer models (Power Delivery), when this is negotiated. So, the main problem arises because the Pi itself doesn’t operate stably. When used with a phone charger, it seems to work, but it often experiences brownouts, freezes, and damages the SD cards. It’s better to use a proper DC-DC converter or an appropriate SMPS rated for 2.5 or 3 amps. Also, if you add external power to the USB hub, it doesn’t hurt to add a few extra capacitors-for noise filtering and ripple reduction, if for no other reason. By the way, if the USB cable lacks data wires-because it’s a so-called “charging cable”-it often happens that even a good charger will charge your phone very slowly. Due to the absence of the data wires, it cannot negotiate with the phone to allow 2 amps, so it does charge, but only at the USB standard minimum. (“The fact that it works is often just Murphy’s trick to let a fault hide forever.”)

I'd like to have a 24 hour display.

5dbm is a compression limit for this thing. Why did you try pushing it so high?

Why? When you found missing -6V You could be check swsp first , you are running aroud the world mate.

Great work!

Why has it been 2 years since your last video?

Bro is a Tektronix hater. Maybe if you knew what all the options on th Tek did you would know why its the way it is.

So helpful ❤

whats the pico farrad and voltage range on that ?

Plz come back and make new videos.

I thoroughly enjoyed your video. Bless Your Bunions!

true DIY)

So we just need to completely cut 5V wire that connect to PC side and use only 5V from external power with common ground?

3:40 I'm politely disagreeing with your hypothesis that the slightly leaky bellows require more air to go through the faster vibrating higher reeds, causing the low end to be comparatively louder. On a physics level, lower frequencies require more energy to make, whether it's flute versus tuba or violin versus doublebass or whatever. In an accordion, the lower reeds have bigger air gaps between the reed and reed plate, whereas in the very high end the gaps get so small that a reed valve isn't even needed. That being said, it may be possible that the lower notes only seem louder to you because their pallet/valve openings are closer to your ears, whereas the volume might sound equal from directly in front of you.

Your black touchpad is a prototype. Lucky you, these are very rare! I stepped through frame by frame and wasn't able to decipher the engraving on the back, would it be possible to get a picture of it that way I can add it to the docs. The calc itself is not a prototype (hardware-wise) but it might have been used for software dev. If you haven't updated the OS, you should check what version its running. It isn't being validated with dev keys so the odds are pretty slim but its still worth checking just in case.

NO Sound Demo !!!!

Nois briwww

Construction is not just rather simple, it's also dreadful simple ! Ok it's the idea that matters. 😄

$5 , you are so full of shit!

I need to build something like this to tune my high frecuency tesla coil

So cool

Absolutely insane video lmao

Good afternoon, your video is excellent, I have an agilent N9310 a. I carelessly put rf in the input and it lost power, it only comes out -30 dbm. I'm looking for the service manual, do you know any link to get it or any suggestions

Thanks for explaining why that wire is better than copper and showing all the info about the wire!!! I was using copper before I saw your video!!! Thanks for showing the package information.

wich resistor do you use for the hall sensor, why they need to be used?

What is the use of 9v battery out there. Does it work on battery without electricity?

My time panel is not working it has number problem is it repairable I mean the no. Doesn't show properly

I got plan to bulid same kind russian button accordeon (garmoshka) but i got no experience so far, i mean with electronics and stuff.. :( Awesome and inspiring video!

Excellent!! Your doing the Lord's work Kid!! Hang in there. I wish there were more young people with this level of wanting to know. Now old people (like myself) have lost that spark. I just tune the loop at low power with a small variable cap, take it loose and measure the capitance, them look in the junk box and find a fixed 50,000Kva that is the same and solder that in. I only need about 100khz to work the CW bands and won't need tuning after setup.

Do you have any Schematic on the project, and it would be Nice to a walkthrue of the code there you explain the code 😊 please please please 😊

Do you have midi on the bas register to? Can you make a step by step tutorial, i have i farfisa accordion That i want to rebuild to midi 😁 Greate video

Do you know which pin corresponds to the "," (ie comma) key? My daughter's comma key doesn't work despite me attempting to clean that key (looks like coffee was spilled near that edge). Probably the actual button contact is deteriorated, but I couldn't disassemble more than I did. I think the social button was sealed if I recall correctly.

Maybe you could shove a bit of rubber so the pins connect better?

i have one that looks like that one. But the needle indicator is misalign with the varicap. with the varicap fully closed the need should be in a 180º angle?

Maybe more complex and superior scopes are too much for you to understand?

It would be far easier and more honest (and shorter!) to just say 'I don't like Tektronix scopes?

Thanks for the video. This helped me understand how the keyboard swap worked for the TI inspire.

Nice one 👍

Great project!

Bro it did not work smh please make a updated video on it please

Wow well done you. If you were this plesent resourceful determined capable and helpful at that young age you must be even more awesome now. Thank you for your video tutorial

Hello my friend... I have one just like this...dropped it on a hardwood floor last night. Now it has no sign of life... I took it apart... the cord still has continuity to the soldered connections...i can't see any broken pieces or broken plastic... I think it hit ground on side cord comes in. Any advice on next step.

If you cut off the center pin of a PL-259 flush with the phenolic insulator, it fits those connectors perfectly!

I will pay you to fix my midi accordion or at least tell me what system I need to buy for it…

@Elecronic Bytes, Nice video man but I got a small question: how do you connect the hall sensors to the esp or better asked how do you power them because the work just with a minimum of 4.5v and the esp32 can deliver just 3.3v... I am a bit confused but hope that you can clarify that to me!

great video!

Great video, but dude why not just but a secondhand Roland.

use a glue gun .

Brother I want to do this to my harmonium. It's modified variant from India.

Is this velocity sensitive?
