Electromechanical Sunglasses IV

[gfish]

I'm in Portland for the Open Source Bridge conference until Friday. My presentation is tomorrow, and I should really finish the slides. But I spent the weekend writing sample SIFT matching and object classifier applications, so the hard part is done. (I'll post the slides and links to the code once it's all done.)

I also got a complete test frame for the sunglasses cut out of wood. Unfortunately, they cracked as I was drilling the gear mounts on them. (Normally, I would drill first, but I wanted to start getting experience with the new jeweler's saw.) So, I'm going to give up on the wood frame idea. They're just too fragile, and I don't want them breaking on the playa.



(Oh god, I do so hate my cellphone camera.)

I also got the electronics completely working, with the photoresistor integrated and everything tested with the new miniature servo I ordered. Next step: a real metal frame, once I have access to my drillpress again next week.

This was oak. But it broke when I was drilling, not when I was sawing. I'd just as rather do it in metal anyway. Wood was fine for prototyping, but not quite the look I was going for.

Ah. I thought you were going to go with brass, but figured that wood can be steampunk as well. Looking forward to the final product.

Oak can be snappy. Redwood's a lot stickier. You could also soak the wood in polyethylene glycol or once you've gotten the form cut but before you drill dip it in epoxy and let it dry.
