Build a Raspberry Pi Camera Robot (Updated)

Hi all, I'm a big fan of Dagu's Mini Driver board, and having realised recently that its 5V voltage regulator could provide up to 1A I've put together a tutorial which shows you how you can easily use it to build an affordable Raspberry Pi Camera Robot that you can drive round using a web browser on a tablet, smartphone or computer.

Hantek 1008B Oscilloscope review

I wanted to watch a lot of analog data faster than Arduino's or MCP3208's could manage, so I ordered a Hantek 1008B a while ago.

Hantek 1008B Review

Since I decided to use it for the HexPi and TBMST tests, I decided to write a review before using it - figuring that if it ended up being useful to me, it may be useful to others.

T'REX tank chassis

It's been a long time coming but the T'REX robot chassis is here!

I've just been testing the final product so I thought I would post a few photos of the new chassis. The chassis is aluminium with a black powder coating. The tracks and struts are zinc with a black anodized finish. The wheels are zinc with a chrome finish.
