This is my first instructable…. ever. So here it goes. I own a Kaossilator 2 (KO2). It’s fun little phrase synthesizer and simple looper. But it has this awkward issue with mic button. When you want to record something from microphone you have to hold down two buttons simultaneously. First the mic button to enable […]

Introduction I obtained an early vintage Radiodetection® RD400 “LLTS” Precision Line Trace unit for a very low price through eBay. The RD400 is the receiver portion of a transmitter/receiver pair that comprise an underground cable locator system. Because the matching transmitter was not available (hence the low price,) I had to design one that matched
