[sdiy] Practical Elecronics "Minisonic2"

[Julian Bunn]

Thanks Tim,

I need to update the site with the latest photos. Right now I have
everything cabled up, and waiting to be transferred to the plastic
sheet panel I had made. I'm actually struggling with a FET opamp
interface to the keyswitch bus which I need to trigger the envelope
shapers. I'm not an an electronics engineer, so this is proving a
bit tricky!

I will also be adding all the circuit diagrams to the site, once I
get permission from the original author, who I am in contact with.

Julian
