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 […]

The SBSAR file is just a 7-zip file.

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.
