I’ve spent the afternoon  staring at USB traces trying to grok the leap motion at a protocol level, no huge progress (most of the time reminding myself how USB works).  I have  at least replicated  the openleap instructions so  can capture raw data.

Here are a couple of  scary photos of me in component stereo (simple red/green and rgb with the blue channel is the difference channel) :

The results from openCV’s stereo correlation aren’t quite there yet : (no doubt due to my coding):




The minority report hand wavy stuff is interesting but I’m more interested to see if I can get one working as a well-calibrated robotics image sensor – the field of view on these cameras is immense (150 degrees or thereabouts)   and the stereo obviously can’t hurt.

Next stop –  fish out an IR laser line from one of the many boxes of bits upstairs (and try not to fry the CCD like I did last time) and do some scanning experiments .

A while ago we visited Becky in London and she took us to Unto This Last on Brick Lane - it’s a really clever operation  - design nice furniture that can be made using a simple  laminated CNC-cut plywood process  and then make it on-demand on a massive CNC mill in the back of the shop.

Sadly they don’t deliver outside of London but it got me thinking whether or not an amateur could follow more or less the same process either at home with a manual router and hand-made templates or using a local CNC service (there are several within a short drive of Bath).

we’ve  been after a TV-stand-come-side board for a while and I’ve been playing around with designing something which could be built using this process:

It would need cutting up to make sensible use of the ply boards (otherwise it would use something like 10 1.2x2m boards at ££ each) but I think it’s doable.

From a home-made perspective I was also thinking it would be cool to make it using recycled wood in small sections and then press it together hotch-potch style.
