Mounting brackets for SRF05 (Open letter to Jack / DAGU)

SRF05 is still IMHO the best low-cost distance sensor.

And there is still no good / smart / fancy / easy / pro / cheap way to mount the darn thing on a turning neck / servo / front..

We now have a good contact to DAGU from China who makes cheap and cool robot-stuff.

So.. I thought.. Why don't we make some suggestions to how we would like such a mounting thing(ey) shaped and made? And then ask Jack from DAGU if he could start producing it?

This was my idea.. and now I need your help and ideas towards the design :)

Theo Jansen style robot leg: prototype #1

For my dreamed symbiotic robots, I am looking for an alternative locomotion. For the passive robot (the trailer) anyway. The active tractor probably needs tracks. I heard Theo Jansen say on TED (improving on the wheel, 4 minutes into the video) that his design for a legged creature is (theoretically) more energy efficient than wheels or tracks.

Where to put all your stuff...

I just wanted to hip you guys to this one. I was at Staples (an office supply place in the 'States) and found some really great boxes. Actually, now that I googled to get an image of them, it seems that they are available in the UK as well --I should have known when I saw they were sized in liters. At any rate, they are simply awesome -and dirt cheap. The smallest one (just the size for resistors) is one buck (about 2/3 of a squid for the Brits).

"Really Useful Boxes" is the name...

Laser Range Finder MkII

This is my second attempt at a homemade laser range finder now with video. I nearly gave up after hearing about the Sharp IR sensors but I think this has potential as it focuses on an area the size of a laser pointer spot. The other sensors work on a much larger area. After a lot of frustration I've finally got all the circuitry working properly and hope to have a video posted as soon as I work out one last difficulty. Click on the photo for a full sized image. This is a work in progress, not a finished product.
