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.

CMUcam Vision Sensor for Robots

Currently selling my current robot platform. Great headstart for someone wishing to build a robot. It includes

Three(3) levels
abt 8" diameter
abt 8" high
omni-directional motor wheel for balance
two servos modified for continuous rotation
UMHW wheels with rubber tires
Wheels have patterns for detecting rotation
Two(2) SRF04 Ultrasonic detectors with housing
Two(2) Solutions Cubed Motor Mind B Controllers
Two(2) Hamatsu photoreflectors with custom circuit boards

Selling on ebay:
Experimental Robotics Platform

Selling my Systronix JSTAMP Development kit on ebay. This is a native execution Ajile Java microprocessor (512K Ram/2048K Flash. Great tool for robotic applications. The ebay link is:

Also selling a new unused 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.

The pc boards from ExpressPCB arrived on friday. I cut them apart and assembled the Intervalometer and the two wheel encoder boards.

I tested the Intervalometer and the board appears to perform as expected. I used my new WARP-13 programmer for the first time burning the code for the intervalometer. The ability to burn code from MPLAB is great. I'll probably toss out my old Parallax programmer.

After spending most of Saturday refining the intervalometer code I have begun reverse engineering the Olympus Remote Control RC-200 to allow the intervalometer to emulate this trigger mechanism, instead of using the micro servo trigger for the EPIC. The system appears to use two pulse groups repeated three times. I want to keep taking samples.
