Imagine the ideal beach trip. The sun is shining, the skies are blue, the water is warm, and the humidity is low. You and your friends have everything you need to soak up the sun, sand and surf: a cooler filled with drinks and snacks, sunblock, flip flops, the coolest new swimwear, and the newest …
The following design is for a Solar battery charger ran by an Arduino Nano. It can handle a standard lead acid 12V battery, like for a scooter or a car. Furthermore the design has been tested and runs with 90% efficiency under 70ᵒC (158ᵒF). It can take up to 20V on the input site of …
It’s been a while since I’ve published my last Instructables. I’m back, and I’m 3D-printed-powered! Enjoy this mini retro arcade machine. It’s literally my first complete end-to-end 3D-printed project: I made the design, printed it, assembled the electronics, programmed it, and now to the tutorial This guide will be updated soon with instructions to finish …

This simple device sits on your desk at work, ready to give you fist bumps throughout the day as you need them. A 3D printed “fist” is moved by a servo attached to a rack and pinion mechanism. An ultrasonic range finder detects when you place your hand near it, and an Arduino Uno controls …
AvrPhone is ATmega128A-based simple mobile phone with touch screen and SIM100S GSM module. The display uses 2,4″ LCD with a resistive touch screen and ILI9325B driver (16 bit parallel bus). The LCD breakout board contains SD card slot and XPT2046 touchscreen controller. They both are connected to AVR’s SPI bus. The project is powered by 3.7V/1000mAh …
