Built an RSR resistor ladder DAC module, suuper easy and seems really promising. Just a cheap mult panel i picked up on a whim, cheap chinese jacks, handful of 10 and 20k resistors chained from the top jack to ground at the bottom. Stole the idea from here -

It's basically a kind of weighted fixed mixer, where the volume of signals is related to where in the chain you plug them in. If you give it multiple square waves you get interesting stepped waveforms, if you give it other stuff you get other weirdness, and you can use any jack as an input or an output :) my kind of thing
need to get my head around whether it would make any sense at all to build a matrix version and if so buiild one :)
Also brought the Eurorack out live for the first time for Cementimental gig in Leeds. :)
it's 2019 this forum really needs to start scaling large images
