Temperature control for a sous vide water bath is a popular application for hobbyist microcontroller kits, with lots of well documented projects out there. My favourite is the Sous Vader – if only for the attention to detail in the decal on the box. I’ve been planning my own for a little while, and got […]

It’s almost a year since I built my Nanode thermometer, and it looks like another really cold snap is headed towards the UK – perhaps snow over the weekend. I’ve not had it set up for a little while, as the TMP36 sensor was reclaimed for a project that put Scratch and an Arduino together […]

In part 1 of this series I looked at ladder board, and in the next part I plan to review the Gertboard. This post is about Quick2Wire‘s boards, where I’ve been fortunate enough to try out some alpha and beta samples. Quick2Wire concept There’s an interface board that connects to the general purpose input output […]

After getting MAME going on my Raspberry Pi so that I could play old arcade games. I wanted to hook up a proper joystick. Back in the 80’s I had the excellent and ubiquitous Competition Pro 5000. As mine (foolishly) got sold with my Amiga stuff I got one on eBay, and it came in […]

I set $son0 a summer holiday challenge of building an alarm system that would send an email (and it seems that I’m not alone). I was pleased to see that the latest edition (#4) of Magpi has an alarm project so we set about building it together. The hardware came together pretty nicely, but the software […]

I first heard about Nanode (a low cost board that brings together Arduino and ethernet) via Andy Piper, then a few days later I had the fortune of seeing its creator Ken Boak speak at London’s Open Source Hardware Users Group (OSHUG). The week afterwards Ken was at the excellent Monkigras event, and did a short […]

The title for this post comes from an old naval tradition, where a ‘make and mend‘ was time given to fix up clothing. These days sailors get their uniform from stores, and personal clothes from shops like the rest of us; so a modern day ‘make and mend’ is simply some time off. With the […]

I often find myself having to rename a bunch of media files. This would be easy if it was just a matter of finding ‘foo’ and replacing ‘bar’. Sadly though I regularly have a list of numbered ‘foo’s that I want to be a different numbered ‘bar’s (e.g. foo_04 -> bar_01, foo_05 -> bar_02). Normally […]
