pcalnon, when you look at the datasheet for the ADXL203, the leads/contacts are the brass-coloured rectangles you can see on the middle picture, right next to the penny. They are all surface-mount devices, so not the easiest thing to work with.
If you can afford it, I highly recommend investing in one of the little Evaluation Boards. You can plug them into any old breadboard and start exploring what they do right away.
Hope this helps!
Hey Steve, if getting the spybotics to drive in a straight line is proving challenging, consider equiping it with a MEMS rate gyro, interfaced via I2C out of a PSoC. The voltage delta out of the gyro is proportional to the turning rate and signed, so it shouldn't be too difficult to do some simple self-calibration and control.
I should have some more time this weekend to continue exploring the PSoC Mini Dev Kit.
Well, I don't think I'm going to make tomorrow's deadline for the contest; a single weekend isn't enough. It's gotten me off to a good start though. It motivated me to power up the MEMS Accelerometer and Gyroscope Eval boards I picked up a while ago.
Ideas and plans are coming together...
...the deadline for submissions is midnight, March 31, 2004!
I'm going to hide out in the basement over the weekend
and see what I can come up with. Fortunatetly there are
lots of related resources available online:
This is one cool family of chips! An interesting way to add reconfigurable, analog sensors and actuators to your 'bot.

I found this site which describes the process for adapting an existing system to USB-boot.
The challenge with the X-board is that the onboard 128MB is the primary IDE partition - /dev/hda - and you can install one other IDE device as the slave - /dev/hda. The bios supports booting from /dev/hda, /dev/hdb (HD or CDROM), USB (mass storage), or network. No second IDE channel for /dev/hdc and /dev/hdd devices. I have a regular IDE DVD-ROM drive and one of those external USB HD cases. I can boot off an HD in the USB case, but stock-Linux installs "forget" that they're running off USB; the DVD-ROM isn't recognized as being a bootable device, so it has to be in the /dev/hdb IDE device mode to be usable.
So now I'm going to try the LFS route onto a bootable USB IDE drive, then use that to build a more compact install into the onboard /dev/hda 128MB flash.
Now if I could just find a source for the 200-pin SODIMM connectors to built a 'bot around this board...
What if, one were to wire up the tracking motor controls on a Quickcam Orbit to drive a robot platform.?. In Windows mode, the automatic face tracking becomes automatic person tracking. :-) The Linux driver supports the pan/tilt capabilities, but I don't expect the pan/tilt is hardware-based, but that's reasonably easy to overcome in software.
Received the P.A.M. samples yesterday. Will start playing with them over the weekend.
This is proving a lot more complicated than expected... Matching up the ink with a compatible cartridge distribution mechanism is beyond the scope of my own expertise. I'm electrical, not a chemical engineer.
That said though, conductive ink pens exist, and older pen plotter printers exist. Should be much easier to adapt the pen to the printer. It won't be as high-res as a more modern ink-jet printer, but it should work. Proof of concept is all I'm aiming for at this point.
