I am selling off my Basic Stamp stuff on Ebay.

Parallax Basic Stamp Development System

I am selling the last of my PIC development environment on EBAY. This includes a WARP 13 programmer, Numerous PIC chips, A series of PIC'N books (including development board), and the Microengineering Labs PIC Basic Pro Compiler.

Microchip PIC Development System

In addition I am selling an assembled and working CMUcam. This camera is specifically designed for small robots.

Also selling a new unused Polaroid Ultrasonic rangefinder.

Polaroid Ultrasonic Rangefinder

I haven't had the time to pursue this hobby so I've decided to sell off my electronics, parts, etc... Looks like I will be selling controllers, bases, BOEbot, stamps, JSTAMP, Javalin and many components of the next several weeks on ebay.

I decided to take a break from working on the bots and celebrate the aniversary of Ben Franklin's kite experiment. Since flying a kite in an electrical storm is a potentially lethal exercise I decided to construct a high voltage power supply and a leyden jar.

I forgot how much fun electro statics and high voltage experimentation could be. I think I might try some exploding wire experiments...

I am still working on the various modules for CIRCE-II; however, even though I have the JSTamp development system the lack of functional hardware is preventing me from developing the software for this system.

I recently decided to purchase the BOE-BOT parts from Parallax along with their new Javalin Stamp Starter Kit. I received the kits yesterday. I've already started developing the low level motor control classes. While the low level hardware control will certainly be different from CIRCE-II this environment allows me to start developing all but the upper level AI code.

Using this approach I can alternate between HW/SW/Sensors. In addition the need to port the software between two different embedded java environments should make for a better software design.
