IFM Grassi standalone

Post by fluxmonkey » Tue Aug 20, 2019 8:42 pm

i'm not a euro guy, but i made an exception for Mssr. Mobenthy, and i have a small rack with one of each, but sadly no room for the Grassi. it occurred to me that, if it's closely related to Mr. Grassi paper circuit it might not need a bipolar PS, and might even run on 9v battery power, which turned out to be the case! et so voila - standalone chaos control

originally i just spliced it on to the power ribbon cable it came with. after this picture was taken, i went back and unsoldered the ribbon entirely and soldered directly to the pads, allowed me to use shorter spacers and generally tighten things up

Have you tried tendrils right angle cables? I could see them being particularly helpful with Mr. Grassi

Another Mr Grassi tip: for some patches you don’t need cables. Try touching it while your other hand is on Mocante, for example.
