Why must palette windows stay on top even if the application loses focus? Characters palette in Pages, I’m looking at you.

Sierra Nevada: I was holding a 6-pack of pale ale when I took this. Guess where I got it from. But seriously, Sierra Nevada is one of the greatest things about living in Chico.

Small Headers: My only gripe about the GPSStix is that the headers are spaced so close together - 0.05 inches. It’s tough if not impossible to find any connectors for it, let alone solder/unsolder anything to it. This is the third connector I’ve placed on the same 8 pins (the center pin is not connected - it’s cut before it reaches the PCB.

Encoder Mounted: This is my ghetto encoder mounted on the back output shaft of the motor with the photogate hot glued to the motor itself. This is a temporary solution!

Encoder Output: This is the output from my ghetto rotary encoder on an oscilloscope that was made the same year I was born. It was quite difficult to get the screen in focus, but you get the idea. Every peak is where the encoder passed through the photogate. Unfortunately the voltage rise is less than 1 volt, so I am forced to make an amplifier circuit. Pics as that happens :)
