Various ongoing projects

The following are projects that I am currently working on. There may be significant intervals between updates on any particular project. I tend to stay focused on one project for quite some time. That is, until I hit a significant roadblock or I become bored with working on that project.

Cypress PSoC

Driving a VGA Display with a Cypress PSoC - How to use a Cypress CY8C29466 Programmable System-on-Chip (PSoC) to drive a standard VGA display.

Robotics!

PanoramaScanCam™ - My implementation of a 360-degree panoramic scanning camera based on a flat bed scanner.
Sixteen-point Digital Compass - A design for a home-made digital compass using IR-LEDs, phototransistors, an encoder disk, and magnets.
Cody's Robot Optical Motion Sensor #1 - A compact design based upon the Agilent/Avago ADNS-2610 Optical Mouse Sensor!

WiFi Support for Brazil Firewall

Out of necessity, I decided to join the wireless era! One of my robotics projects uses a laptop with a wireless network card for connectivity. Consequently, I needed to have a wireless access point on my network. I could have bought a wireless access point, but I learned a lot more about WiFi by taking an existing Linux rounter package and adding wireless capabilities to it.

The Brazil Firewall (BFW) router distribution is a derivative of the Coyote Linux (CL) Personal Firewall distribution. Since I have been using CL for a long time, it was a snap to switch over to using BFW. I picked up an AirLink 101 AWLH4030 Super G Wireless PCI Adapter from Fry's Electronics and started reading and experimenting. So far, I have succeeded in creating a basic access point (AP), an AP with WEP encryption, and an AP with WPA encryption using hostapd. The details can be read in my BrazilFW WiFi How-To, v0.3.
