The SF Zoo is a great place. I loved my morning. But SF has a bit of a homeless problem and they know how to spot a rental car. I had my stuff in the trunk and they broke in just to see what might be there.

I have started building my quad copter. It is a 3D quad copter design. It has GPS, altimeter, three way gyros, sonic ground detector, magnetic compus, camera relay and radio telemetry.

Today I bought a Spektrum upgrade battery from my DX8. The SPMB4000LPTX Transmitter Battery from my local hobby shop. After plugging in the new batter and turning on the radio, the radio bused (normal if you have the throttle up) but then it popped and smoked. The battery leads reversed reversed. I didn’t think to check the polarity from the original equipment manufacture. The original batter is on the left and the new (BAD) batter is on the right.

Seen on my way home today. You would thing this would be mundane for me because I work across from the sever storm lab.

I’ve started a new electronics project. Think camera meets Arduino. Photoduino is as an existing project. I’m using a Arduino mega to add a stepper to drive a dolly on a track and take pictures.

I meat many nice people on the bus.
