Systems Tested

By dragoncoder047

Over winter break I was able to get some more progress done building circuits to get closer to an upgrade of my old, broken Roboraptor. There are a zillion different components to this project, and I wanted to test each separately to make sure they work before I make a …


Reverse-Engineering the Feedback 360

By dragoncoder047

Some time ago I ordered one of Parallax’s “Feedback 360” servos for a robotics project I’m working on. I wrote a little arduino library to control it, and it works well.

As-is, however, the servo itself is too big to fit where I want it to. I’m …


Two Down, A Zillion More To Go

For starters, the process is slow, annoying, and tedious:

  1. I click UPLOAD, and the Arduino IDE begins compiling by … dumping preferences.
  2. It then has to shuffle …

A few months ago I stumbled upon two old 1990s-era Armdroid 1000s in the back of my engineering teacher’s storage closet. Naturally, being someone interested in robotics, I wanted to see if I could get them to operate.

Unfortunately, I didn’t know diddlysquat about how they worked. So …
