New here. Purchased a few of the Mad Labs Jr Theremin kits. I’ve put 4 together and all have the same issues. Thinking there is a component issue or an issue with the PIC chip. The issue is when powered on, it does a self test which all of mine pass. It then starts beeping 2 tones every 10 to 15 seconds. Tons of folks out there are having the same issues with the new kits. I was wondering if anyone has had the same issues I’m having and did you solve it.
Hey i have the same problème
