Charles picked up the robot arm Kurt was getting rid of tonight. Thanks, Kurt! It’s beautiful. We took it apart, and took pictures.
Just before he silently stole away on a secretive mission to distant lands, Ranjit left a hoard of lovely obsolete electronics at the lab. Among the treasures were a couple of old counting units with 7-segment incandescent displays, sometimes called numitrons. I’ve turned this one into a simple clock.
Thanks to Charles for the spare pushbuttons, Ranjit for the original unit, and Evil Mad Scientist for the protoboard.
A quick note: our R1 filtration droid finally gave up its wee little electronic ghost this week, so the laser will be unavailable until replacement parts arrive. The L2 and L3 filters apparently took a little more carbon scoring than they could handle. We expect we will once again be vaporizing materials in futuristic fashion within a week or two.
Inspired by Kelly’s experiments with laser-cut sponges, I cut myself a few Menger sponges
Query: what the hell is this thing I’ve been lugging around for the past three years?
It’s some sort of StrongARM development system. I think it may be related to the Intel “Brutus” eval boards, but I’m not certain. The daughterboard is labelled “SA1110 daughter card”; there’s nothing useful on the larger board. There’s a fairly anonymous StrongARM chip in the ZIF socket. It feels like some sort of demo unit, given how it’s all gussied up and under acrylic.
What’s on the big board?
Intel sold off all its StrongARM/PXA properties years ago, and scrubbed pretty much anything useful from its website. Archive.org hasn’t been too helpful. Anyone have any leads?
