Since my last post, I have completed my junction box and I have prepared 3 motor/speed controller assemblies. I have acquired a second leadscrew to use for my Y-axis, and the electronic portion of the construction (except for limit switches)…

Converting .MTS video files into .mp4 files
I have a Canon HF200 video camera and it outputs HD video, but it’s in .MTS file format. This is a pain because there are no good free video converters or editors for .MTS files. But using Avidemux, an open-source…
Initial DIY CNC Prototyping
I’ve started constructing the basic electronics for the CNC machine I’m working on. It’s going to be a cheap machine made with what I have on hand, so accuracy won’t be great, but it should be an interesting experience. The…
EC155 PID with Arduino
This is a build log of my PID modification to my DeLonghi EC155 espresso machine. Currently, the machine uses an Arduino to drive a solid-state relay controlling the heating coil. The Arduino displays mode and temperature on a serial lcd,…
The OSRAM SLG2016 and AVR
I happened to scavenge a couple of SLG2016’s from some old workstation debug displays. After finally locating a datasheet, I realized that they used the standard ASCII charset, so they are extremely easy to drive. Note: The SLG2016 differs from…
DIY High-Quality Block Printing
Ever wanted to cover your wall with a nice high-resolution DIY poster? With a little bit of effort and a lot of paper, you can make a high-quality block-printed poster with free, open-source software. This method produces a nice smooth…
Macro video and photos with the S3 IS
With a couple bucks worth of cheap macro filters, you can get great macro video and photos with the Canon S3 IS (works with the S1 or S5 IS as well). All you need is a lens adapter that fits…
JavaScript “Current Filename” Function
I found the need to get the current filename, without the file extension, of a webpage using javascript. I thought there would be an easy way with jQuery, but I found a good way to do it in plain javascript.…
New “Projects” Pages
I created a new “Projects” type to list some projects currently on protofusion. Check out the link in the top menubar, or click here. Have a project that needs some of the resources that protofusion can provide? Send an email…

Victor Speed Controllers and EMC2
I’m currently working on building a EMC2-controlled CNC machine with mostly parts I have on hand. I decided to use Victor 883’s to control my servos, but EMC2 does not put out the RC-style PWM signal that victors are driven…
