Nice. I've seen that mentioned before. I think I even have a PT2399 that someone gave me in a grab bag of parts. That's far more complicated than my simple circuits. I do have a question for you... Do you know much about getting PCB's made? Cost etc. or who to contact?
That's cool. I just got into it in July. I had NO experience at all. I caught on to stuff quickly, but as far as calculating what does what and why... I consult with insonicbloom for that stuff. You looking to sell eventually or just tinker?
