Adjustable Constant Current LASER Diode/LED driver

“I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is …

Automated Garden System Built on Raspberry Pi for Outdoors or Indoors - MudPi

“Do you like gardening but can’t find the time to maintain it? Perhaps you have some houseplants that are looking a little thirsty or looking for a way to automate your hydroponics? In this project we will solve those …

Automating Blinds with a Retrofitted External Motor

“It’d be a real stretch to say I needed to automate the blinds in my apartment, but it was fun, and I’m loving the result. Blinds open automatically at sunrise and close at sundown. It’s nice to …

DIY Temperature Controlled Chamber Box With Peltier TEC Module

“I have assembled Temperature Controlled Chamber Box for testing small electronic boards. In this tutorial I have shared my project including source files and link to Gerbers files to make the PCB. I have used only cheap commonly available materials …

Mini High Voltage Jacob’s Ladder

“Today’s build is really simple but really cool looking miniature high voltage Jacob’s ladder. We assemble “15KV high voltage generator kit”, get some basic working principles about Jacob’s ladder and maybe some more general tips and tricks …

Optically Isolated Bidirectional I2C Shield For Arduino

“Optically isolator Arduino Shield has been designed to provide optically isolated I2C communication between Arduino and any other device or sensors that works with I2C protocols. I have used the ISO1540 Low-Power Bidirectional I2C Isolator IC from Texas Instruments to …

Wireless Soldering Iron

“Wireless soldering iron - that sounds weird. Sometimes I feel like soldering outdoors, but I can’t take my soldering station outside. I bought a USB soldering iron, which worked quite well, but needed a little modification, because what if I …
