Collaborate Disseminate
A mechanical and manufacturing engineer by day, [Tyler Collins] taught himself electronics and firmware development in his spare time and created an open source Lego controller called Evlōno One. It is based on the STM32 and Arduino ecosystems, and compatible with a impressive variety of existing Lego controllers, sensors …read more
The Shanghai Evolution Shift company has just pulled off one of the most impressive robotic projects we’ve ever seen – making a building walk using 198 robotic legs. We’ve all seen structural relocation documentaries where large buildings are moved to new locations. This involves jacking up the building and installing …read more
User [mircemk] presents his “MiliOhm Meter” project which you can build with an Arduino, a handful of common parts from your lab, and a cigar box. It doesn’t get much simpler than this, folks. While this is something you won’t be getting calibrated with NIST traceability, it looks like a …read more
Do you ever wonder just how many punches you have thrown? The answer is going to be different if you happen to use a punching bag as part of your exercise routine. So is the case with the [DuctTapeMechanic] and while restoring an old speed ball punching bag, he decided …read more
An open-source canine training research tool was just been released by [Walter Arce] and [Jeffrey Stevens] at the University of Nebraska — Lincoln’s Canine Cognition and Human Interaction Lab (C-CHIL).
We didn’t realize that dog training research techniques were so high-tech. Operant conditioning, as opposed to Pavlovian, gives a positive …read more
The Japan Aerospace Exploration Agency (JAXA) recently contributed their Int-Ball technology to a Kickstarter campaign operated by the Japanese electronics manufacturer / distributor Bit Trade One (Japanese site). This technology is based on the Cubli project out of the Swiss Federal Institute of Technology in Zurich (ETH Zurich), which we …read more
A recent writeup by Tom Nardi about using the 6502-based NES to track satellites brought back memories of my senior project at Georgia Tech back in the early 80s. At our club station W4AQL, I had become interested in Amateur Radio satellites. It was quite a thrill to hear your …read more
If you thought your home-brew project was taking a long time, [Jeroen Brinkman]’s MERCIA Relay Computer project probably has you beat. He began working on this impressive computer back in 2014, and has been at it ever since. In fact, the ongoing nature of the project is embedded into the …read more

Volos Projects educator [Danko Bertović] had a TTGO ESP32 board looking for a project, so he implemented a surprisingly functional weather station for such a small screen. Presumably that was too boring for him, so he decided to write a version of the classic Atari game Breakout instead. [Danko] prefers …read more
