Subject description: Lunetta module
Reply with quote  Mark this post and the followings unread

I finished another lunetta module. This time it's a shiftregister with a couple of XOR gates. One XOR gates is used in
the feedback path from the last stage to the data input which allows the bits to be inverted. This setup is also used
in the turing machine and rungler and I did make it to produce sequences when connected to an R2R. However
just using the outputs of the shiftregisters directly seemed a bit boring so I added some XOR gates.

With the loop switch open it functions as a regular shiftregister (except for the outputs of course) and it doesn't
matter if the invert or data input is used. Of course both can be used too. I also added the last output stage which
could be patched back to the input through something else, like an AND gate for example which would be the
equivalent of a digitally controlled loop switch.

I secured the PCB to the panel with some hot melt glue, seems to work pretty well.

What kind of material is that face plate made out of? Some sort of faux Wood?
