Last night I participated in the first part of Make:DC's workshop on building, programming, and using motor controllers. This first evening we soldered together a driver board. The next part will be adding an arduino, programming it, and wiring it up on a platform with an actual motor or two.

The other day, for fun, I dissolved a spare SmarTrip card I had laying around. Here are the results. Turns out I could just have read this DCist article, but where's the fun in that? I was inspired by the folks across the pond dissolving their Oyster cards, but since the SmarTrip's antenna is more ephemeral (i.e., dissolved) than the Oyster's, I'd need to solder on my own antenna if I want to try using it again. This could make a fun HacDC project.

And in a final bit of geek news, I'm proud to be a temporary custodian of The Great Internet Migratory Box Of Electronics Junk. I'm still going through the contents, but once I figure out what I'm taking from it, I'll take some pictures before passing the box along. Actually, I might be taking some pictures so I can get some help in identifying some of the contents... Update: Here are pictures of some of the items I couldn't identify.

If the chip from that Smartrip card is still good, why not make it into a bracelet?

Wave your wrist at the turnstile, and it "magically" opens!

C'mon, you know that'd be cool...

I like that idea. I'm going to look into it.

So that's what happened to that SmarTrip card I couldn't find!

Oooooo geekery! Very cool.

That's so awesome. I always love reading your posts on this sort of thing; it's a sort of hacking that I've done very little of, and so it has that fascinating glamour of "holy crap, I have NO IDEA how that works, but it's AWESOME". [grin]

I've been tempted to sign up for one of the migratory boxes. I have all sorts of little magnetometers, accelerometers, and gyro chips that are just aching to get integrated into a project like this.

Re: Box
Would you like a turn with this box? Just say the word, and I'll add your name to the recipient list.

Re: Box
I added myself to the box wishlist on the wiki they set up. Anything else I need to do?

Re: Box
Nope, nothing else you need to do. You'll be the next recipient of the "Yokohama" box. :)

Re: Box
Box received. I'm sorting through the junk now. The OCD side of my personality is forcing me to straighten some of the IC pins and put them in a block of foam.

That, and I think this box will soon have a full rainbow of LED colors.
