Those are great. we use them as distance sensors in our mini sumo robots.

The coin cell provides about 16ma to the flying saucer with nothing else in the circuit. I put in a resistor to dim it somewhat (and mounted it backwards). I'm thinking about some sort of tiny pot for brightness control or maybe a LDR in a voltage divider as crude auto dimming.

Those look great! I've been doing a much more stripped down version with just pin backs for lapel pins and a coin cell. I've gotten a couple full days out of the ufo on the first battery and counting...

$369 each vs $6 for 2 (plus jumpers). I think I'll stick with the traditional ones and save the blinky lights for the projects I build on them.

BoB finished this out with a snowflake effect palm rest and some nifty software. www.youtube.com/shorts/cmsYV...

Unfortunately, neither Whizzo nor my goth-bot Cuddles have been successful in competition.

Your maps are very interesting. And thanks for putting me on to the NFIP interactive mapping source while looking at relocating to a flood-prone region (Annapolis area).

The final version is more egg shaped but with careful indents to encourage the fingers of variously sized hands to grip it securely.

I try to make the electronics of these projects as visible as possible to inspire conversations about making at events.

The next versions were designed to be gripped or wrist worn since the light cube responds to vigorous movement and shaking. But people at our recent makerfaire revealed that this was too cumbersome and slow to adjust to hand size differences.

At this point the hardware is ready save for the acrylic palm rest for scanning. My friend BoB will do the software and provided fresh muffins and a quick game of Fyra at the handover.
