Yes, it was a bit of an ordeal. I kept putting if off in favour of
easier modules (stuff from Paul S. and my neural agonizer). But now
that I've done one Miniwave and written down every wire length and
LED resistor value and triple checked that I have all the parts, I
figure the other Miniwaves should take a weekend each to build.
That'll be a good winter project.
I forgot to mention that I measured the current draw at 103 mA on the
positive supply and 28 mA on the negative supply (that's with 8 PROMs
currently installed). I'm running my LEDs quite dim so you may need a
even more mA on the positive side if you like to run beacons. This is
something to keep in mind if you are already stressing your power
supply.
