Is that possible to use couple of 1N4148 diodes(3.3/0.7 = 4-5 ones) instead of 3.3/3.6V Zener ones?
And sorry for terrible question, can I just feed 5v on a USB as a temporary solution? (I'll have Zeners in about 2 weeks, too slow....)
Will it immidiately burn PC's controller (provided that's a spare PC, and I can sacrafice it )
Using usual diodes instead of Zeners
Re: Using usual diodes instead of Zeners
I have seen people using 1N4148, and I have powered many projects on another +5 power source.
Re: Using usual diodes instead of Zeners
I would try it without diodes 1st. Supposedly 80% of USB hosts will tolerate it and the ones that don't will just refuse service to the device, not burn up

Thanks for reply.
I think I'll just leave placeholder for zener on PCB, and will just work without them until I would get one
I'll let you know results...

Ok, finally device works.
It works fine without zenerz and without usual diodes for both 3.3(kinda expected) and 5v supply on both my PCs.
