SuperFlux “Piranha” LED testing

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.

cMoy Headphone Amp

Intro

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.
