Project FR4 Mill Complete!

Last night I finished soldering and connecting the last bits of the FR4 milling machine. I also checked for any shorts, then powered up the Arduino to see if it would light up all the drivers and confirm everything is working. Sure enough, it did!

I hope to get a real test cut done soon, but I have a lot going on tomorrow and through the weekend (my wife’s cousin Julianne’s wedding). I also have to install the control software on a laptop, so I need to dig one up.


Last night I wrote up a page and a half document about solenoids. I wanted to write it up in a way that a parent/child team could read through it and grasp the basics of how solenoids work. I explained a little about electromagnetic fields, how flipper solenoids work, and a few safety tips. This educational write-up will hopefully be a part of the starter kit documentation when it comes out.

The Pinball Expo

Last weekend I was at the Northwest Pinball and Arcade Expo in Tacoma WA at the Fast Pinball booth. It was a fun show (but so loud) and I have no voice left today at work. I realize that what I do is pretty niche stuff and not something most people are interested in, but I still got a lot of questions and comments about my custom stuff. Even my flippers, which I didn’t think much of, got some attention.

I’m excited to be working with the Fast crew, they are great, and have built a great community. My efforts here will shift somewhat as I assist them in preparing their pinball kit for launch, but stay tuned for updates. There will be new stuff coming down the pipes!
