Notes: Lots and lots of plans. Gradually accumulating parts and equipment.
My New Year's resolution is to get more involved in robotics stuff by way of involvement in the Ottawa Robotics Enthusiasts group.

Check out the next round of Mark Tilden's Robosapien line of 'bots!

I dropped by Best Buy yesterday and picked up one of their cheapest Logitech optical mice (CDN$14.99+tax).

I opened it up today and sure enough, it's using an Agilent ADNS-2501 sensor. It's in a DIP package (yes, the pins along each side are offset by 0.05" as shown in the datasheet), has quadrature outputs, an SPI, and if you look on page 33-34 of the datasheet it can dump out the 16x16 pixel image it's "seeing".

In short, with the right optics you have a single, low-power chip that can see 2D motion and capture images to pass up the processing chain. Get two and you could have some very interesting stereoscopic motion control potential.

It's a hackcident just waiting to happen!

My pack of ultracapacitors arrived yesterday. Now all I have to do is make time in between work and caring for a newborn to start work on my Sapien Autopsy to graft them in as a battery replacement power system...

Jin, brilliant as always. I like how you wired the ADXL202E on DIP8 socket for test; I'm going to have to borrow that idea.

In other news, my two Robosapiens arrived, but not before the baby arrived, so deconstructing them will have to wait. I have a few ultracaps on order (thanks Steve), my goal being to replace the battery-based power system with caps in one of the Robosapiens and rigging up some solar trickle-charging to keep them topped up.

Ah yes, if you buy more than 100 ultracaps they only cost $22 each. No I didn't buy that many; I asked when quantity price-breaks kick in.

Steve, thanks for the link to those 350F caps!

Any idea on the cost and who might carry them?
