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 […]

Needy Jelly Babies
Two years ago I took my son along to Maker Faire UK in Newcastle (which is where I grew up). This year the whole family came along. Whilst I queued with the kids for the ‘laser caper'[1] my wife went along to a talk by Clive from the Raspberry Pi Team. I can’t blame her […]

Sous Vide Roast Beef redux
Last week I cooked tri-tip with my Raspberry Pi controlled water bath. This week I used a much more ordinary cut, some topside from my local Co-Op supermarket that had cost me just over £5 for 1.6kg. Some time ago I stopped buying this kind of meat because if you cook it per the instructions […]

Best roast beef ever
I cooked tri-tip with my Raspberry Pi controlled sous vide water bath today. It came out brilliantly – on a par with the best Chateaubriand I’ve had (which for the record was at Casa Ferlin in Zurich – well worth a visit if you’re ever in that neck of the woods). The meat I got […]

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 […]

OpenELEC 3.0 Released
OpenELEC 3.0.0 has been released, which means that this popular distribution for XBMC is now in a stable version on Raspberry Pi. Raspberry Pi downloads for an SD card image file (.img.zip) and a copy of the release bundle (.tar.bz2) are on the Pi Chimney resources site. I’ve done some tidying up on the site, […]

Presenting with a Chromebook
I decided to use my Samsung ARM Chromebook for a presentation at Brighton Pi last night. It did not go well. Creating the presentation Using Google Docs instead of Powerpoint was pretty straightforward. I never do much fancy with my slides – usually just a visual anchor or a few bullet points, so no real […]

I first came across GreenQloud at GigaOm Structure Europe last year. It’s a cloud service based in Iceland that is powered entirely from renewable energy. I bumped into Eiki and Bala again last week at London CloudCamp, and gave them my sob story about hosting. They’ve very kindly offered to provide free hosting for my […]

After bringing my Nanode based temperature sensor back to life I thought about some other projects that I might do. One was simply to add an external sensor to the Nanode project, and another was to turn my slow cooker into a sous vide water bath (along the lines of ‘Sous Vader‘). Those projects would need […]
