Converting a micro servo to continuous rotation
Say you want to build a small robot, but you soon discover that DC motors move too fast and geared DC motors are too expensive. Then you hear about servos. Servos are basically geared DC motors, and microservos seem just … Continue reading

Micro Servo Gear Pry Tool
In the process of converting a micro servo to continuous rotation, it is necessary to open the housing and pry the gears off the servo base one at a time. However, my fingers are just too big and clumsy to … Continue reading

Surgery on a servo
Servo drift occurs when the potentiometer shaft (the one on the left in the photo) turns from the centered position (ie 90 degrees). I tried to prevent servo drift by soldering the pot shaft in place, but apparently all I … Continue reading
Servo Center Location Test
It looks like the climactic scene in a monster movie, Arduino vs. Bot. In reality, this setup enables me to keep the ATMega328 chip on the Arduino while I upload test programs to locate the servo centers. According to the … Continue reading

Mini Grisbot in Sketchup
It’s about three inches long by two and a half wide. Driven by two micro servos, controlled by an Atmega328 microcontroller. I think I’m about ready to put in slots and tabs and take it to the laser cutter.
Continuous rotation micro servo
Here are two Hextronik HXT900 microservos which I have modified for continuous rotation. These will provide the propulsion for the latest version of Grisbot. HXT900s are about the cheapest microservos out there. I’m planning to buy mine at Hobby King … Continue reading
