“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 …
“A pocket-sized debugger for monitoring serial data. Description Sometimes you need to quickly check the state of the device and having to use a computer for that can be a bit bothersome. A pocket-sized debugger that can monitor and display …
“This module is an isolated full-duplex differential line driver and receiver for TIA/EIA RS485/RS422 applications. The module is ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range …
“With a code size of 1KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps. There are a lot of so-called “USB doctor” modules which are used for monitoring currents …
“Ever since the 80’s I’ve wanted to build a Z80 computer. I even bought the chips, but never used them. The reasons for this are varied. I never liked erasing and reprogramming EPROMs. My EPROM eraser died. I …
“Having a fascination that borders on obsession with light I decided to create a selection of small modular PCBs that could be used to create RGB light displays of any size. Having made the modular PCB I stumbled on the …
“24-bit stereo DAC which is specially built for Raspberry Pis. This R-2R DAC delivers the clear audio output with minimum configuration. This project is about 24-bit stereo DAC, which we build for Raspberry Pi boards. This R-2R ladder DAC is …
“An Arduino version of the game Mastermind where you can try to guess the computer’s number or it can try and guess yours. Story After looking at the Knights Tour puzzle which was based on the Krishna Lalith version …
“An alien-themed slot machine powered by an ATtiny85 microprocessor. Odds and payouts emulate typical slot machines found in casinos. A while ago, I was looking at the Arduino Slot Machine by seawarrior181. It seemed a good project to modify and …
“Get not only 5 volts but also 9, 12 volts (18 Watts max) out of any QC-compatible charger/power bank for supplying power hungry projects. Introduction Many USB powered consumer electronic devices have built in Qualcomm QC (Quick Charge …
