Build an ‘Arduino’ on a Raspberry Pi

This is, after all, supposed to be a blog about Raspberry Pi. With all the stuff about Arduino and Atmel AVR chips, you might think I have wandered off. However, just to prove that Pi and ‘Duino work well together, here’s how I hand-built a board to sit on the Raspberry Pi GPIO pins and …

HotPi multi-purpose board

This is turning out to be a great week for new stuff. Yesterday I got a package of goodies from China and today I got a HotPi board from local Raspberry Pi specialists “The Pi Hut”. The board was funded by a kickstarter project. Unfortunately I did not know about it until after the kickstarter …

Back to soldering

Yesterday morning my car was at the garage for a service, so I took the morning off work rather than struggle in using public transport only to come straight back again to pick it up. I took the opportunity to break out the soldering iron and construct some Raspberry Pi boards, one of which has …

Soldering a slice of pi/o

A few weeks ago I bought some interface adapter boards, including a Slice of PI/O, which came as a kit of parts in a little zip-lock bag. I had a day off work today. Not for a good reason, unfortunately – it was my aunt’s funeral in the afternoon. But it did give me an …

Gertboards and microcontrollers

Last month, when I found my Raspberry Pi again and started this blog, I had a look around the web to see what was happening in the world of Raspberry Pi. One of the things I kept bumping into was the “Gertboard” – an almost mythical input/output expansion board, named after Gert van Loo, its …

Know any stackable, single Raspberry Pi GPIO connectors?

Yesterday, in my review of the LEDBorg, I wrote about how it can be inconvenient to connect two devices to the Raspberry Pi GPIO header at the same time, especially when one of them has a header which covers all the pins. I mostly write and run my own bare-metal software on the Raspberry Pi, …

Hardware review: LEDBorg for Raspberry Pi

Introduction A while ago I ordered and received a LEDBorg bright, three-colour LED for my Raspberry Pi. I wanted to have a go at writing software to drive the GPIO pins, but didn’t want to go to the trouble of building my own hardware. Not only would that be fiddly, but if (when) something did …
