Hacking an IKEA mirror [part 5]

I needed a case for the RaspberryPi. The good thing about the RPi being a business card-sized computer is that it fits nicely in a plastic box from old business cards. If you look on Ebay, you can buy 20 of them for £5 including delivery.

The boxes make fantastic custom RPi cases! I didn’t spend too much time and effort in cutting these accurately, but the result is fine for the purpose. All the necessary ports are exposed and the GPio cables have a custom hole.

The board fits snuggly in the box, so I did not bother fixing it. A bit of bluetack was used to stick the plastic box on the metal frame.

Hacking an IKEA mirror [part 3]

Step one was to draw the positions of the buttons on a piece of paper. I secured the drawing with some tape. P1000883_small

I first drilled pilot holes, then used a 16mm metal drillbit to widen the hole.P1000891 copy

 

A step drillbit was then used to accurately widen the button holes to the right size.

An additional hole was added for the tablet charging cable.

The tablet stand was created from scratch, using a perforated steel sheet I had in the workshop.P1000904 copy

 

I drilled a hole first and then, using the vice and a piece of wood as a guide, I gave it the right shape. The gap is wide enough to accommodate even a 10″ tablet.

For now it holds an old Google Asus Nexus tablet

An angled USB charging cable makes the connection looking quite neat.

openWRT device from Omnima UK

29 Aug 2011
Omnima UK sell a tiny little board for less than £40, that runs on openWRT Linux and has ethernet, WiFi and a USB port. It seems to be a great base for simple projects, when we need more power than one arduino.

Link to product

I’ve ordered one to try something I have in mind.

Btw, at the openWRT site, there is a VM available. I downloaded and tried it yesterday, but I had problems connecting USB peripherals…. Never mind. I have to say I loved the web interface and the precompiled binaries and the fact you can ran python on it!

I’ve now received the device. It runs Fonera (have a look at some screenshots and more info here). Easy to access through a web interface. I tried to load the latest Fonera software and it didn’t quite work; now the device won’t boot. I’m able to log in to it using telnet and a serial cable, but I haven’t been able to load the old bin file yet… I’ll keep you posted…

WiShield from async_labs

This past week, I got my hands on a WiShield 2.0 from Async Labs (http://www.asynclabs.com/).

This is a very exiting addition to my collection of shields as it adds wifi capabilities to my projects!

There is a nice wiki page on the async_labs site (http://asynclabs.com/wiki/index.php?title=AsyncLabsWiki) and relevant code (libraries & examples) is hosted at the GitHub (http://github.com/asynclabs/WiShield).

I have a few ideas about this shield – stay tuned! :)
