I’m planning an LED floodlight project that will use a lot of square 4-pin LEDs, aka SuperFlux or “Piranha” LEDs. I hadn’t had a chance to use these type of LEDs until now, so after receiving my order this week I immediately went to work on trying them out. This won’t be a very technical review, just a quick look at the specs and my experience with testing the LEDs and what I thought of them.
The cMoy Headphone Amplifier is a popular, well-documented DIY project, which makes it great for beginners to take on. That’s exactly the reason I chose to do it. I followed the instructions and suggestions from the TangentSoft cMoy Tutorial written by Warren Young, and it came out great, especially for my first attempt at building a headphone amplifier.
I won’t get into how I built mine (the tutorial at TagentSoft is where you should go for that) but read on if you’re interested in seeing what parts I used and some of the problems I ran into.
