Frequently Asked Questions - Hardware

If we agree not to call a few wires and resistors a programmer, than no, you don't need a programmer.

You either power it from a computer through USB or from a +5V power
adapter capable to give 500mA. Many mini usb power adapters will do,
e.g. a power adapter from my I-mate SP5 phone.

Yes, you can. In that case you don't need 6N138N and everything
directly connected to it and to the MIDIIn/Out.1 connector. In the
current MegaDrum32 schematic these are R25-R29 and D1.

Yes, you can. You don't need a USB MIDI I/O board/option. You will still need to provide +5V to MegaDrum.

Yes. You can use any inductor with a value between 10uH and 1000uH (1mH)

Very much likely. I have my own drawbacks, point me out to the error
and with your help we'll fix it. The important thing is that MegaDrum
works as I designed it to work even if the whole MegaDrum circuit is a
big schematic error:)
