TV Cable Tidy


TL;DR If you’re putting a TV on a modern open stand then the ancillaries and cables can make a real mess and spoil the overall look. I put a board onto the VESA mount on the back of my TV to hold everything, which then let me arrange the cables into one tidy trunk running […]

TL;DR I hacked together my own USB shaver charger using a cheap DC-DC converter I bought on eBay, so fewer worries (and things to carry) next time I’m travelling. Background I use an electric shaver most days, and I travel a fair bit. Usually the battery is enough to get me through a trip, but […]

I spent Saturday manning the @BrightonPi stand at Brighton Mini Maker Faire showing off various projects with Gareth James. It was great fun, and I really enjoyed talking to people about the potential of the Raspberry Pi. There were a few questions that got asked a lot… hence this post. The projects I was showing off […]

Sous vide steak


After making my Raspberry Pi controlled hot water bath over the weekend I’ve been itching to try it out. I got my chance this evening when cooking some steak for dinner. I get my steaks mail order from Donald Russell, so they come shock frozen and vacuum packed – so the ‘sous vide’ part is […]

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 […]

TL;DR I haven’t got this working (yet). There may even be limitations to the hardware that mean this couldn’t work. The general idea was to use a cheap ($4.99) Texas Instruments Stellaris Launchpad (LM4F120XL) board in place of a pricier ($34.95) Dangerous Prototypes Bus Blaster. All of the basic pieces seemed to be there – USB […]

A while ago I bought an STM32 dev board from China on eBay, as it seemed to have so much more than the official Discovery boards coming with: A 2.4″ LCD with touch screen input 4 Pushbuttons (and a Reset button) 4 LEDs 2 Variable resistors A Micro SD slot A buzzer RS232 2 USB […]

The screen on my wife’s Lenovo s10e gave up the ghost last week. I thought it might be just a loose connector and that I could fix it, and an initial attempt at strip down and rebuild seemed to work. Sadly my fix didn’t hold. I’ve been using my own s10e mostly to play videos […]

I wanted to add some diagrams to my original post, but didn’t have the right tools at hand. After some digging around I found a mention from @psd of Fritzing. I’m pretty happy with the results: I’ve put the Fritzing file up onto github, and also created a project on the Fritzing site.

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 […]
