New Pulsar card. other stuff.

Thanks to a kind PlanetZ member "Capacitor" I have now got another pulsar card. it was free! he said it was karma for things i have done for the scope community at  PlanetZ
And because my card was dead, soniccore also tranfered the keys for free as well.
This one appears to work well, and i will be doing tests this weekend.

I have received some LM1875 circuit boards from Chipamp.com for the string driver amplifiers. they were very generous, I ordered 4 sets of 2 amplifiers + power supply board and ended up getting 10 sets!

The electronics components i was missing for the amplifiers also arrived  building the amplifiers has started.

The little switches i had been using are no longer being considered. Each key will consist of 2 opto interrupters and a pressure sensitive resistor for "poly aftertouch" and a bit of mechanical work. (3d model coming soon)


This means i can no longer use the Arduino2009 because it does not have enough inputs, so i have ordered an Arduino "mega"  it has a lot more I/O.
