eMac Cat Bed

eMac Cat Bed

This one was based on an article I saw on Engadget about a cat bed designed by Samuel Cox made from an old eMac and integrated with an Arduino unit allowing it to tweet each time the cat used it.

A quick search on eBay and I found a stack of suitable units for as little as 99p and thanks to travelling with work I was able to arrange a pick up to suit. 20130526-220256
The disassembly proved a little more challenging than expected, having assembled and disassembled PCs in the past I must say that the Mac is far more complicated than and the CRT screen proved particularly challenging as I wanted to remove the case and front from the mountings without damaging them.

The final task was to stick some soft fur cloth to the inside to make it comfortable and insulated and encourage the cats to use it.

Arduino

Arduino

Today I bought an Arduino starter kit, it’s a simple electronics kit that not only includes the Arduino board itself, effectively a small computer that can be programmed using a simple programming language, but also a selection of components, a breadboard for wiring the circuits and a book of simple projects to get you started.

The Arduino is designed to make prototyping quick and simple for hobby designers and engineers. It’s open source so is being constantly developed and updated and now features a variety of versions from the smallest and simplest designs for small objects or even clothing applications through to large complex boards with many inputs and outputs and even a complete robot.

I’m keen to get back to electronics engineering, if only as a hobby so decided that this was a good place to start. I’ll be updating the blog with a few of my projects as I go along, although as I try to remember my anodes from my cathodes and inputs from outputs it may be more flashing LEDs and buzzers than autonomous vehicles or another Asimo.
