Finally I've made a working battery based portable soldering iron. This one can melt solder in under 10 seconds, which is amazing. The soldering iron weighs just above 100 grams, is comfortable to use, it can reach more than 300 degrees, it's very fast, we can recharge it with a USB co... view more

In this tutorial I show you how I've build a homemade electronic load with Arduino, an LCD, rotary encoder for the menu and a power MSOFET for load control. It also has a good cooling system so it could handle high loads. See how to make the circuit, the case, connect everything, see the code I'v... view more

Desde hace algún tiempo, quizás más de un año, quería hacer mi propia extrusora de filamento 3D para reciclar piezas impresas en 3D viejas o malas. Pero una extrusora de filamento necesita algunas partes, como el motor, la extrusora, el bloque de calentamiento, el proceso PID, pero tamb... view more

For some time now, maybe more than a year, I wanted to make my own 3D filament extruder in order to recycle old or bad 3D printed parts. But a filament extruder needs a few parts such as the motor, the extruder, the heating block, the PID process but also to mesure the diameter of the output fila... view more
