The Waveform Gateway Oscilloscope is a nice, inexpensive Eurorack oscilloscope. The instructions on how to build this are detailed in issue #2 and can be found on our Build Guide page. This is an intermediate build. Faceplate width is 14HP and is black with copper.
IF YOU PURCHASE THE PCB + COMPONENT SET YOU WILL NEED TO PURCHASE AN OSCILLOSCOPE.
DO A WEB SEARCH FOR JYETECH DS0 138 MINI. MAKE SURE YOU GET THE CORRECT ONE. YOU DO NOT NEED THE ACRYLIC/PLASTIC HOUSING/CASE THAT COMES WITH SOME OF THEM.
