Awhile ago my fellow during one of our weekly LabChats the topic of conversation we discussed the possibility of using an air cannon as the first stage of a model rocket. Here's a video from a creator who is exploring that possibility. He's using microcontroller to determine when the vehicle reachers the highest point in it trajectory. I think we could do much better, but I'd like to share this and see what everyone thinks. Enjoy!

This is by far the clearest explanation I've ever seen on the nature and benefits of cycloidal drives. These are far superior for many applications, especially in robotics, where you need high torque delivered at relatively low RMPs. If you have any interest in building things that move, you've got watch this video. Enjoy

If you've ever wanted to build cool microcontroller-based projects, there's no longer any reason to wait. This $50 kit allows you to create and program your own devices to create almost any device a mad scientist could ever need. From the Website: "Genesis Mini is a modular, Wi-Fi-enabled prototyping system built around a standardized AX22 connector. The ESP32-S3 powered board provides eight AX22 ports that modules plug into directly. [...] This platform eliminates breadboard wiring for common tasks like sensor reading, display control, and motor driving." There are dozens of transducers that cover all the mad-science bases. The system can be programmed with AI, so all you have to do is tell the system what you want your device to do and it will create the code to do it. Make remote measurements, control a network of your own devices with Wi-Fi, host your own website on a server that fits into the palm of your hand. Bring the world to its knees! Now it's all embarrassingly easy to do. Check out the website to see what you think. It's amazing the power that you can get for less than $100 these days.

Here's another of my favorite YouTube Creators... This time Bill Hammock explains how we extract and purify copper from raw ore. It's really clever! Please enjoy.
