Agile Code Games

Recently, some of our members did some code katas with TDD. If you haven’t played them before, code katas are intended for practicing coding to become a master (hence the martial arts reference… well, that and nerds will be nerds). There are several handy sites that people submit code kata ideas to that you can use for practicing.

Sending commands from one XBee to another XBee mounted on Arduino Uno

So here’s the setup.

The goal of this project is to send a serial command from the XBee on the Dongle Board connected to a computer to the XBee on the Arduino Uno and have it turn the relays on and off.

Making our own PCB – Etching Copper Clad Boards

A few of our group in Boulder, CO, joined a workshop hosted at the Solid State Depot on the electronics design process, making our own printed circuit board (PCB). The first class went over how to actually design circuit boards before we etched the copper boards and soldered on the parts to make it all work. Actually etching the boards and building the circuits was the best part! First, after you have designed your circuit and created a sketch of how the copper board should look, you want to get that drawing to your copper clad board. And you can do that with a laser printer.
