Second: What is a simple way for connecting arbitrary arcade controllers to the RPi? In the following we present the ControlBlock, a Raspberry Pi (TM) Add-On that solves both problems.Read More »
The acrylic case “Petrockblock Pie” was presented some time ago. The design files for that case were not publicly available until now and I have decided to change that: You can find the design now in the Downloads section!

A while ago I posted a review about the reflow-flow oven T-962A. As written in that post the T-962A has certain flaws: The heat is generated by IR heaters that do not distribute the heat evenly within the oven. This made the results of the soldering processes unreliable. Also, the responsiveness of the user-interface is not that good: Tuning the reflow …Read More »

If you are tinkering, doing electronics, and/or soldering you might already have had contact with surface-mounted devices or, in short, “SMDs”. Of course, soldering some of these tiny parts by hand is possible. But there are really tiny SMD parts as well as packages that cannot be soldered by hand. In that situation, you can think about getting a reflow …Read More »
