Lasers

A while back I decided for safety reasons not to put laser cutting capability onto my Art Bot. So, the laser and heatsink bundle arrived today. I’m going to be messing with the voltage and current using a dummy load (also bought that, rather than scraping it together) and nothing could possibly go wrong.

I’ve already written the software.

Motion Sensing

I’m trying to use a Raspberry Pi 3 and camera for motion sensing and recording. Here’s how I’ve got on so far:

  • Arch: Didn’t fucking work. motion started and kept dying. Power throttling killed the SD card.
  • Jessie Lite after buying a new SD card: wpa_supplicant didn’t fucking work.
  • Jessie Lite after three hours dealing with wpa_supplicant: motion didn’t fucking work.
  • MotionEyeOS: Required wired network to start for the first time. Walked back and forth between screens a lot. Can only alter root password through web interface. Weirdest fucking distro I have ever seen.
  • MotionEyeOS with a set-up script: May actually have fucking worked.

ETA: It fucking worked!
