“For a while I wanted to get back into making some projects with microcontrollers. Last time I touched any microcontroller code was a few years back when I tried to make a heating regulator for a friend with Arduino Nano …
“I love the look of old 1920’s radios. They are the embodiment of a decade. The radios that I like the most were vacuumtube cathedral radios made by Philco. When I think of old-timey radios those are the first …
“This is a back EMF signal conditioning circuit that can be used to develop high-voltage sensorless motor drivers. When a sensorless algorithm is used to control the BLDC motor speed, the Back EMF (BEMF) signals are used. Based on zero …
“I’ve been building a retro computer, and it’s gotten me interested in using cassettes as data storage. This poses an interesting challenge where binary information has to be converted into something that can be written to, and reliably …
“Are we neglecting the importance of water? Probably, the answer is YES. Go through this different and versatile project to find a solution. Before diving into the Hardware & Software setup, it is important to first understand what the project is …
“Fully 3D-printable hydraulics for all your robotics projects Recently saw a video of Boston Dynamics it’s Atlas robot doing all kind of awesome stuff and learned that the robots were fully hydraulic. I was wondering if it would be …
“Low frequency oscilloscope using OLED display OLED low frequency oscilloscope, bandwidth is DC to 1000Hz. Max sampling rate is 16000 samples per second. An oscilloscope with these specifications has limited use, but it is a good exercise in using OLED …
“I have a portable bandsaw that I absolutely love- it’s one of my favorite and most useful tools. Cutting small pieces of metal with any degree of precision can be difficult however. What I needed was a stand to …
“How about getting rid of that broken volume knob on your stereo and replacing it with some buttons, LEDs and Bluetooth? What is it all about? It’s a rather detailed (hopefully) description on how to replace a stereo system …
“In this project, we will upgrade a traditional shortwave superheterodyne receiver with an Arduino base tuner. This tuner is capable of receiving shortwave broadcasts on 41m band and above. This modularized receiver consists of a transistor base mixer, I.F …
