I found this sweet Mini Space Rocker circuit by the same guy that makes the Drone Commander. And seeing as he has 25 different sounds up on his site i had the idea to make a few different ones and then put them into one enclosure, but it has only one at a time running off of a nine volt battery. But Im pretty dumb when it comes to the whole altering circuit combining things Ive only built some BYOC kits and Im wondering if I would be able to put the perfboards into one enclosure and wire them all onto one 9 volt jack so i dont have to use a bunch of batteries or buy another dc brick that i cant afford. Heres the link to the site with the schematic and everything if anyone can help me out before i start ordering the parts.
