Singing in the shower is such a common phenomenon, rarely anyone ever bats an eye about it. Singing in the toilet on the other hand is probably going to raise an eyebrow or two, and it’s not for nothing that the Germans euphemistically call it “stilles Örtchen”, i.e. the little silent place. But who are […]

The OpenScan project has been updated quite a bit since its inception. OpenScan is an open source, Arduino or Raspberry Pi-based 3D scanner for small objects that uses 3D printed hardware and some common electronic components to create 3D scans using photogrammetry; a process by which a series of still images from different angles are used to […]

In ridiculous times, it can help to play ridiculous instruments such as the slide whistle to keep your bristles in check. But since spittle is more than a little bit dangerous these days, it pays to come up with alternative ways to play away the days during lockdown life. Thanks to some clever Arduino-driven automation, [Gurpreet] […]

Whenever a project calls for displaying numbers, a 7-segment display is the classic and straightforward choice. However, if you’re more into a rustic, retro, almost mystical, and steampunky look and feel, it’s hard to beat the warm, orange glow of a Nixie tube. Once doomed as obsolete technology of yesteryear, they have since reclaimed their […]

The thickness of the acrylic being used is a .25″ sheet, which cuts really cleanly by the laser cutter/engraver (the one that I had access to is the Trotec […]

IV-27M Alarm Clock Project date: March 2019 – May 2019 Overview After the successful completion of the XIV Nixie Clock which was Direct/Static Driven, I was keen to start work on a new clock which was based on the Multiplexing(Dynamic) or “MUX” principle of operation, known also as “Muxing”. The new clock would be based […]

Here on instructables weather stations have already been introduced. They show the current air pressure, temperature and humidity. What they lacked so far was a presentation of the course within the last 1-2 days. This process would have the advantage that you can not only graphically read the current values but also at a glance, […]

I’ve been looking for cloud data storing for a long time during last years: it is interesting to monitor data from any kind of sensor, but it is more interesting if these data are available everywhere without any storage difficulty such as using SD cards or similar, in local storing.I used to local store on […]
