The Valden HeatPump controller is an open source platform to precisely control heat pumps. Automation of newly built HPs, old systems repair

Let's build an Arduino FM Radio with a 3D printed Art Deco style enclosure!

No need to purchase any propriety systems, this is a stand alone unit operated by a free App called 'LocoMotive'

A complete wire quiz buzzer system for 4 players using nRF24L01 radios with included TP4056 based battery charger and sound effects

An Arduino powered floppy diskreader/writer for making and writing disk images from and to AmigaDOS floppy disks, works winUAE too

An innovative wearable technology for visually impaired peoples.

let's build an RGB LED CUBE using NEOPIXELS and PCB

Protect lithium polymer battery pack from over discharge.

This ouija board gets a life of its own, with the planchette vibrating when it approaches certain letters - and it opens a lock!

Make a long range remote controller for your robot.

Make your own motor driver shield PCB for an Arduino Pro Mini using an Arduino Pro Mini.

Step aside, an amazing six-wheel off-road robot coming through! Check out this Arduino-based wireless surveillance DIY RC robot.

These Smart Blinds automatically open and close according to ambient light levels, and also close in response to heat.

I needed to set a large number of ds18b20 sensors up and I had to record the address and position of each sensor.

Sunglasses that serve an even more useful purpose than protecting the eyes of the blind. They can help them detect objects in front of them.

A tri-color personal slot machine with a 3D printed realistic lever to spin the wheels.

Low cost smart vitals wearable which can help in early detection of COVID-19 in front line workers

A pair of talking smart glass, intended to help the visually impaired.

An autonomous high speed line follower robot based on PID control.

This project is about a shortwave trasmitter from 3 MHz to 30 MHz. It uses the SI5351 oscillator from Silicon Labs controlled by Arduino.

Last year I did my first version of my Automatic musical (Christmas) Lights which worked super great but It came with some drawbacks.

Lets build a NRF transmitter using arduino

An Arduino based MP3 player with 30 levels of volume adjustment, 5 levels of EQ adjustment, and a pretty cool retro looking UI.

Hygene is one of the most important thing at our life. With this project disinfectant liquid is able to spray to hands touchless.
