So I have been bouncing between very busy and ill, but I have had 2 opportunities to take the Glowforge into the Wild at East Kentwood High School.
We at least had some shade, but were setup outside. Obstacle 1? Heat. For the record, I did NOT use dry ice at the air intake and on the edges of the bed to help maintain operating temperatures inside the unit, but that could be effective for a Pro, at least.
Obstacle 2, Internet. After the Glowforge resisted switching to my phone as a hotspot, I changed my phone name to my home Wi-Fi. When setup at the school? It took a few tries, but both my laptop and my Glowforge connected to my phone (which had issues staying up). This tells me the #1 concern for normal Maker Fair attendance would be Wi-Fi with filtering being the other. Since I was setup outside, filtering was not much of an issue.
Edit: Note, the hose was not left turned to the ground once I got to burning. It was just sitting that way while I was getting setup. The second day, I didn’t bother to setup a hose.
Some of the stuff on the table was items you’ve seen me make before. The big item for attendees (and hardest thing I’ve made) were the engraved batons.
Which I was customizing some on-scene, but they take longer to burn.
The one other item I had there was from running into some green marble at the local ReStore. Of course, I had to play with it
