This one is still my favourite benchtop power supply, but I broke it recently, so it needed some repairs. This was also a good opportunity to try out my new Gochifix 3 in 1 scope meter. Review on that meter coming soon Amazon link for scope meter, and discount code: amzn.to/3VN7klZ Discount code (25%off): 25MathRS

Building a camera platform with a long lens on it to follow the sun and make a timelapse of the eclipse. Some interesting shots captured with it, and talking about light levels during the eclipse

Testing some AS5600 magnetic encoders to see how accurate they are by rotating a magnet in front of them using stepper motors. The sensors are quite precise, but getting that magnet centered enough to get accurate readings is difficult. Yet at the same time, the magnetic encoder was able to measure step and microstep angle erros of the stepper motor. Also showing how to interface the AS5600 to ...

Lots of experiments with optics and lenses to project an image of the sun on a piece of paper to make it easier to watch the upcoming total solar eclipse. We happen to live in the path of totality.

Somehow my main channel got hacked again. Not sure how they got in, but I realized letting my browser store passwords was a big mistake that made it much easier for the hackers. Check if you are still subscribed to my main channel: czcams.com/users/matthiaswandel

How to figure out what all the wires do from a random top-loading washing machine. These are simple resistance start induction motors that are easy to re-use. Motors for front loading washers are very different and much less practical for re-use.

I bought some "closed loop stepper motors". Experimenting with what they can do. I'm impressed by their power, ability to get back in sync, and less stringent real-time constraints for driving them. More tech stuff: woodgears.ca/tech

The fall of Blackberry. Where did we go wrong? In retrospect, I suspect RIM (Blackberry) was already doomed even before its heyday. The entrance of Apple and Google changed the game, and RIM could not adapt fast enough. 00:00 In brief 00:26 1993 Start first modem module 01:25 1995 Start first integrated messaging device 02:18 1997 Start what would become blackberry 02:50 1998 Blackberry! 03:43 ...

A youtube comment lead me to try another experiment, revealing why the pipe ends up getting lifted up from suction. This is a follow-up about my Feynman sprinkler video with the levitating code and mysteriously levitating piece of straight pipe

Trying to reproduce the Feynman sprinkler experiment, I tried a few more things, and then it got interesting. I love experimenting with fluid dynamics. I figured out why the straight tube would also lift up: czcams.com/video/z3scTRJCm7w/video.html

Comparing different types of heaters and infrared heaters. Not all heaters are equally effective at directing the heat where you want. The big square on is from Sunkos (just google it) The wall mounted heater is from Dreo, model WH729S Search for "celing mount heater" for the black infrared heater.

I bought a geiger counter, but there was nothing radioactive around the house, until I discovered you can gather radon decay products using electrostatically charged baloons! The article I referenced: sciencedemonstrations.fas.harvard.edu/presentations/radons-progeny-decay
