Personal goal: refresh basic understanding of modelling and control.   […]

E-ink notification and weather display

I love e-ink displays. Their ability to make something digital seem just a little bit analogue intrigues me and I just had to make anything that makes use of one. Like many, many other people on the internet that turned out to be a weather station. The initial aim, seeing as I was already going […]

RetroPie Arcade Part 4 – Completing the build

 Part 1, part 2 and part 3 of this build can be found in the links. In this post we will look at how to complete the build now that we have Retropie running on the Raspberry Pi, the screen working and an enclosure to put everything in. Controller The initial planning for this project I included […]

RetroPie Arcade Part 3 – The enclosure

Part 1 and part 2 of this build can be found in links. The size of the enclosure, and the whole system, was completely dictated by the size of the screen I decided to use. The initial idea was to buy cheap portable game systems from eBay, remove whatever was inside and replace with my […]

RetroPie Arcade Part 2 – The screen

Part 1 can be found here. My aim for this project was to fit the largest screen possible that I would consider portable. Just based on availability and the screen sizes of cellphones I decided that 5″ was the size to aim for. For  reasons I cannot remember this did not happen and I settled […]

Spanwerk en bronbeheer met Bitbucket

Projek 3 is om saam te werk. Vir daardie doel is bronbeheer nodig waartoe almal toegang het. Bitbucket bied die antwoord. Bitbucket Wat is Bitbucket? Bitbucket is ‘n diens vir “cloud” bronbeheer. In plaas van self ‘n toegewyde bediener vir bronbeheer te skep gebruik jy Bitbucket as jou bediener. Dit maak dit maklik om dan enige […]
