This thread is for discussion of details related to my challenge project. I'll post my progress here and we can discuss it in this thread.

[edit] here are the chips in my bag:

Bag A
4001 x 4 quad 2-input NOR
4011 x 2 quad 2-input NAND
4013 x 6 dual DFF with set/reset capability
4023 x 2 tripple 3-input NAND
4027 x 1 dual J-K Master-Slave FF
4051 x 2 8-channel analog multiplexer/demultiplexer
4068 x 1 8-input NAND
4082 x 2 dual 4-input AND
4093 x 3 quad 2-input NAND
4518 x 2 dual BCD up counter

Here's a photo of my entry thus far. It has a pair of SRF oscillators going into a ringmod and those three outputs into an 8 position spatializer. Need to add an emSynth stereo out jack to complete this sub circuit.

8 position spatializer?! How are you going to drive 8 speakers?

I'm outta money and outta time, but I'd like to try and participate in this eventually.

Of course! That would be the greatest help however I'm currently in the process of moving house, so there will be a delay before which it can be sent to a house in which I will be living Laughing

(P.S. In america it might mean something different, like poor, but here in England tight with regard to money means that one is reluctant to spend the money which one has. I would spend some money on this if I didnt have other pressing purchases to make, like stuff for the new house and sheet metal for my synth, these are just greater priorities for me right now and they will take up all of the £30 I have remaining to my name Rolling Eyes

so I hope you aren't suggesting I'm a miser Surprised

I was thinking out loud in chat with the folks there and realized that I could make a hybrid digital / analog KS loop that might make interesting sounds. It would use the 12 DFFs that I have as the delay line, an RC low pass circuit for the filter, and a piggyback NOR/NAND pair for the inverting summing amp. Might sound pretty good, and would certainly be worth trying out.

I get the parts on Monday for doing this. Looking forward to it.
