One of the most fun and useful projects on instructables is to create your very own solar USB/ iPhone charger. They’re not overly difficult to make, nor are the parts overly expensive... Read more
Rather than use the USB to power my Arduino board with a handy trip to the electronics store with some more knowledgeable people than I, I have constructed a 9Volt DC power supply. Taking a... Read more
When I’m building Solar Shrubs and other solar-powered creations, I often scavenge cells from various off-the-shelf devices such as solar garden or security lights. But these cells are... Read more
This is super simple but very useful if you are in a hurry or just like to do things yourself and on the off chance you didn’t know, this is about the easiest way to add mobile power t... Read more
If you’ve ever wanted to power your Arduino or AVR from a battery for development testing (batteries have different power delivery qualities than, say, transformed AC or even a regulat... Read more
Overview The Arduino Fio is a microcontroller board based on the ATmega328P (datasheet) runs at 3.3V and 8 MHz. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8... Read more
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 pin... Read more
Hello everyone, and welcome to my Instructable! This instructable will show you how I made the first ever DIY Arduino controlled “LED Kaleidoscope”! What is an LED kaleidoscope?... Read more
This project is an update of my original Peak Power Tracker Battery Charger Project. It is designed to control a 12V solar panel charging a 12V lead acid battery. The updated version of this... Read more
I bought a solar powered garden light. The solar panel charges the batteries and when it gets dark the lights (3x LEDs) turn on until it either gets lights again or the batteries run out. It... Read more
