This is an Instructable about a mini oscilloscope I made, it isn’t anywhere near as capable as a real (digital) oscilloscope (such as my Rigol) but I think it is nice to have. Even more important, I enjoy making things, even when they have no real use. For an example of that, just look at […]
Overview I grew up watching Star Trek: The Next Generation. I’ve always wanted to build a Star Trek themed device, so I finally got around to remixing one of my old projects to make a Star Trek Display Terminal. The terminal provides the following information: Weather – using the National Weather Service Indoor Temperature, Humidity

When I build my previous mini oscilloscope I wanted to see how well I could make my smallest ARM microcontroller a STM32F030 (F030) perform, and it did a nice job. In one of the comments it was suggested that a “Blue Pill” with a STM32F103 (F103) might be better, smaller than the development board with

“Star Trek”, “The Terminator”, “Star Wars” or “The Avengers” – in each of these films technology was on a cosmic (literally) level. The heroes used laser weapons, which always fascinated me. I decided to build a laser gun, but I would not use it to kill people or aliens, but to compete with my friends a little. As I decided
Who does not want to have stunning lamp which can display animations and sync with other lamps in the house? Right, nobody. That’s why I made a custom RGB lamp. The lamp consists of 256 individually addressable LED’s and all of the LED’s can be controlled via a smartphone app. Additionally, you can build multiple
