I’m building an SMD reflow oven from an abandoned toaster oven I found in my garage. In my last post I described my adventures and innovations with sheet metal, ceramic insulation and Reflect-A-Gold tape. I think I did a good job with that.

Most of this […]

HC-SR04 octopus on I2C plus one pin

I recently had my first encounter with ultrasonic distance sensors – specifically the Parallax Ping))) – while helping the Cresta Blanca Girl Scouts robotics club prep for the local RoboGames Fire Fighting challenge. This got me all interested in doing robot things again so I’ve dusted off […]
