After my first batch of Clamps badges sold out on Tindie, I was lamenting that I didn’t have any spare boards to put rainbow LEDs in. Jon Raymond suggested that I could go one step further and add an ATtiny85 and some RGB LEDs. Not one to turn down a challenge, I started work!
Over Christmas I stumbled across a cute Meeple lapel pin, which I of course bought. While it works well as a tie pin, I’d like something a little closer to the real Meeple size for my coat, so as soon as I got back to my PC I had to try my hand at making a PCB version.
This is the second part of a series investigating the use of optical sensors for robot odometry.
In part one of this project I pulled apart an old Microsoft Intellimouse for the optical chip and managed to extract some readings using an Arduino Uno. The aim now is to repackage those components in a way that they could be mounted underneath a small wheeled robot. (more…)
