“32 bit RISC-V homemade In this article I will describe how I designed and made a functional 32 bit RISC-V CPU at home. Specifications: “Max” clock speed: 500 kHz Program memory: 512 kB RAM size: 512 kB VGA …
“A UV Exposure Box to expose photoresist or solder masks for single and double boards. Most of the projects that I build have a custom printed circuit board. With a preference to making my own PCBs rather than use proto-boards …
“The project presented here is a wide input voltage range non-isolated DC-DC Converter, that provides a regulated, adjustable output voltage. The operating input supply is 55V DC and output regulated from 1.2V to 50V DC. The project built …
“The major challenge of making a smaller LED cube in my opinion is the LED panels. Commercially available panels are designed for video walls and typically made at 64x64 pixel as a minimum size. This seems to be a good …
“The circuit presented here is a 3W stereo audio amplifier with memory UP/DOWN volume control. The project is based on PAM8408 IC from Diode Incorp which is a filter-less class-D amplifier with high SNR and Differential input which helps …
“What we are going to do here today is how to make a cool LED cube at low cost A LED cube allows us to create images and patterns by using the concept of an optical phenomenon known as persistence …
“I’ve hit a pretty significant milestone with this Instructable - my 200th! It’s been a busy 9 years, building and learning a lot of new skills whist producing these 200 ‘ibles - and it’s been a blast. Thanks to …
“I designed and built my own EVSE EV Charging station from scratch because I wanted 2 stations with each 22kW support (3 phase, 400V, 32A) and “real-time” current & voltage measurements on all phases - in order to be able to do …
“It’s a Walkie-Talkie based around the ESP32. It transmits audio using either UDP Broadcast or ESP-NOW. We’ve made a Walkie-Talkie using the ESP32. Audio data is transmitted over either UDP broadcast or ESP-NOW. So the Walkie-Talkie …
“This project provides 8 fully protected and isolated high-side power switches that are able to handle current up to 625 mA. An 8-bit parallel microcontroller compatible interface allows connecting the inputs directly to a microcontroller or standalone circuit system. The …
