Arduino Inductance Testing
In yesterday’s post about the progress on my big switch mode supply I mentioned that I was going to try building an Arduino based inductance meter based on the basic and straight forward design from Shadi Soundation. I built the meter later in the evening. It seemed to work okay, but the numbers seemed odd when […]

Large Switched DC Power Supply For Argon Laser Project Log 1
I’m in need of a large DC power supply for an argon laser and other projects. Argon lasers require tons of DC power to produce minimal amounts of output power, thus the power supply needs to be pretty beefy and durable. I also like building things and having projects to work on to help keep […]

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 […]

High Density WS2812B Panel Project
Posted on March 16th, 2014 in Arduino, Custom Projects, DIY Equipment, Electronics, LEDs, Lighting, Teensy, Video
The WS2812B RGB LED chip is a wonderful little device. It contains Red, Green and Blue LED elements and also a WS2811 RGB LED driver. The chip has only 4 pins. Power, Ground, Data In and Data Out and can easily be chained to another chip. With enough of these chips chained together your can […]

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 […]
