Reverse Avalanche VCO See http://www.kerrywong.com/2014/03/19/bjt-in-reverse-avalanche-mode/ for the arrow's shaft size. // Scale factor for the overall arrow size. Engraved_indicator_scale = 1.01; // Height (in mm). If you use knurled_cyl() module, you need a hole, set this to the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that.
