Sam and I met on Friday and reassembled Peppy from it’s sad party face:


(It fell from the ceiling due to a very heavy HDMI cable after I tore out the USB port of the servo board through more incompetent ceiling mounting and things just went from bad to worse as the night wore on and I attempted solder, gorilla glue, psychobabble, …)

We took the opportunity to better-document how to build a Peppy. These are the things you need:

Sam’s working on a few sketches of the milled parts, and I’m thinking of posting the instructions to lowerquality.com
