I've been trying to make a good ESC for years. My first prototype 3 years ago was working "good". It was very big and the BEMF was not that good. It could reach decent speeds and you ahve that tutorial here on this page. Now, with my final version I have all taht I wanted. H... view more

This, is version 2 of my very powerful coilgun. As you can see, is huge and it has quite some power and works with high voltage, so please, I can’t stress this enough. Never touch the high voltage parts, stay insulated, use proper tools and if you don’t know what you’re doing... view more

Hi guys. This here is my design of a coilgun which is a project I was preparing to make for a long time and I finally made a first version. Before we start, I have to warn you that this is a quite dangerous project for 2 reasons. First, well it fires projectiles at high speed. And se... view more

This PCB is a metal detector. The circuit is very easy and I will do my best in this tutorial to explain to you how it works. I use real examples and animations in the video below so you will understand everything. The PCB is interesting because it already has the coils on the board made with ... view more

This is my first version of a smart-glasses multimeter. Is not the most unique and best look design, but this is yet a first version. I’m pretty sure I will improve it in the future. Anyway, inside the 3D printed case, we have a custom-made PCB that I will show you later, a Bluetooth mod... view more

Usually, each time I have a project with a small battery that I also want to charge, I use a small charging module with USB connector. But then, all the other digital components usually work at 5V, but the battery is 3.7V. So, for that I add another small module, a boost converter to give me 5V. ... view more
