Last week I was out shopping at one of my electronic resources and came across some big Mitsubishi CM200DY-12H 600 Volts 200 Amp IGBTs. I bought two pairs of them for my future projects. Below is a picture of a pair of them on the nicely machined heatsink. The overall length of the heatsink is about […]

Built a Skew Planar and Cloverleaf Antenna for my 900Mhz FPV Setup
I was flying in an industrial are the other day with my FPV setup and even when the picture was clear it would go all rainbow colored which was very distracting, additionally my range seemed to be shortened quite a bit. It looked something like the photo below which has been photoshopped since I wasn’t […]

Toaster Oven Reflow Controller Project
I had a project I was working on which needed to be reflow soldered because there were too many parts too close to each other to solder by hand. I needed to get a reflow controller up and running quickly. I made the little controller shown below by mixing a few easily available kits and […]
