I recently purchased a new Samsung Ativ book 8 from BestBuy. Here I’ll document a few tips and tricks I found when installing both Ubuntu and Arch on my new laptop.
»Spirit Circuits ‘Go Naked’ PCB Prototype Review
I recently used the free ‘Go Naked’ service from Spirit Circuits to produce a prototype PCB used in a sous-vide controller. Overall I was extremely satisfied with the service, although I couldn’t quite believe it was actually free to begin with, so hopefully this short review will give others an idea of what to expect.
»Sous-Vide Controller Part 2 – Building and Testing
I previously wrote about designing a temperature controller for sous-vide cooking. Here I will go through the process of building and testing the controller.
»Sous-Vide Controller Part 1 – Design
Sous-vide cooking involves sealing food inside a bag (generally in a vacuum) and immersing the bag in a water bath at a carefully controlled temperature. Generally the water bath is kept at a fairly low temeperature – around 60 °C. By using such a low temperature it is possible to cook the item to an even temperature throughout, so a steak could be cooked to medium all the way through and then seared on the outside to give a result like the picture shown at the top of this page.
