Recently, I visited an Anime and Cosplay convention. Although I rarely watch any Anime, I do enjoy crafting costumes and in particular steampunk-esque things. Of course, I could not let the opportunity pass. So I decided to dress up as a steampunk gentleman. Nixie Tubes I always wanted to build something with Nixie tubes. Those are cathode vacuum tubes, which… Read More →
Of course, there is always a Need for Speed in racing simulations. But sometimes, there is also the Need for Smooth Drifting Around Tight Corners. And pressing a button on my steering wheel controller just doesn’t cut it in terms of control and realism. So, I set out to acquire a handbrake controller, but quickly decided to build my own… Read More →
During my adventures with SDR (software-defined radio), the need for a proper QFH antenna arose. This type of antenna is used to receive signals that are circularly polarized, such as APT weather maps sent by the NOAA satellites. I used a PVC pipe and a standard shielded coax cable from the local hardware store, and a copper tube meant for… Read More →
A few years ago, in 2017, I attended a rather large music festival. Apart from the music and general camping experience, one thing particularly got stuck in my mind: Someone wearing a beer crate as a backpack. While one could argue this not being an unusual sight at a music festival, the thing that impressed me as a maker were… Read More →
After completing the machnical construction of the laser cutter, it was time for the control circuit. I used a perfboard PSB and soldered headers for the Arduino and stepper motor drivers to it. On the bottom, I connected everything up. The limit switches needed some simple debouncing and smoothing on their signals, because the cables were so long and the… Read More →
In 2016, I built a CNC laser cutter / engraver. I always wanted to document the whole process, but never got around to do so – until now. Enjoy a multi-part series on how my build went! Before I start, a word of warning: Lasers can be very dangerous to your health, eyes and general envoirement if misused. Please make… Read More →
