The BBC micro:bit is a computerised project board that’s being given to every year 7 (11-12yr old) kid in the UK. It’s supposed to encourage experimentation and learning to program in the same way that the BBC Micro (and associated BBC programmes) did back in the 80s. I’ve been pretty excited about it since the announcement, […]

I’ve been very happy with the results from my Raspberry Pi controlled water bath for sous vide cooking, but I knew that the control loop could be improved. Past runs show fairly continued oscillation: I’ve been keeping track of the average power for my control loop, which has been coming out at 22%. So i […]

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 […]

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 […]

Leaks of (badly secured) password files seem to be big news at the moment. In many cases people set up sites to allow you to see if your password was in the leak – but who knows whether these sites are trustworthy. That’s not a risk I’m happy to take. Python provides a reasonably simple […]

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 […]
