Actually I have a design that can be used on the black and white models. I'm just very busy right now and can't mass produce them, but I'll sell you my one and only prototype. I can also release the files at some point, but I'm very busy right now so I will not be producing more at this very...
If one just wanted to control plugs via the power key(without any software) on an ADB keyboard the process would be fairly simple. Because the ADB keyboard grounds the power pin whenever the button is pressed you could just use a set of relays in a holding circuit like this (but with ground and...
Yeah I guess, Basically you can't fully charge your batteries together with a 7.5v charger, you need at least 9 volts to charge a 2-cell lithium battery. In charge mode, my circuit splits the batteries so the can be charged individually, but doing this has the downside of the batteries not being...
I see, It might be worth to check the rectifier(KBL08) and make sure it's okay:
Also check the capacitors on the left side of the rectifier.
OR if your board is newer:
