    Egg Decorating Bot

    I started this project in 2017. My original goals were: Don’t use a 3d printer or laser cutter. Build the frame out of foam core. As you can see in the thumbnail, I gave up on the foam core, but I stuck it out on the no 3D printing or laser cutting, just to prove […]

  • Running Raspbian in image on Ubuntu desktop

    While the title says Raspbian on Ubuntu, the steps will be nearly the same for any ARM linux distribution on any AMD64 Linux desktop.

  • Dynamic Wireless Network Name (SSID) on Raspberry Pi hotspot

Unfortunately, it seems that to just pip install kivy appears to work, but then when you run an example, it complains about missing libraries, and installing those […]

  • Substance Designer SBSPRS/SBSAR file format notes

    I have never used Substance Designer, so I’m basing this off of looking at example files. The SBSPRS files are XML that appear to specify the list and type of parameters used in the SBSAR substance. The SBSAR file is just a 7-zip file. It expands to: ./assemblies ./assemblies/content ./assemblies/content/0000 ./assemblies/content/0000/icon1234567890.png ./assemblies/content/0000/Example.xml ./assemblies/content/0000/Example.sbsasm The Example.xml […]

  • In case anyone is interested in making USB connectors a bit more kid proof, I recently bought these magnetic USB cables: https://www.amazon.com/gp/product/B074TB8XTLFor the kid’s tablet, I super glue the micro-usb adapter in place. It sticks out about 1/8 in. No more kid destroying USB ports.It’s like Apples MagSafe for tablets.For their claim that it will […]

  • Makita Reciprocating Saw cord replacement

    I was planning to nicely document this, but on review, some photos don’t really show what is needed, then I got caught up in finishing it and didn’t take appropriate finishing photos. Oh well, here is what I got.
