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 […]

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? Well, our traditional kaleidoscopes used 3 mirrors joined as a triangle with stuff like sequins and stolen cake decorations at one end, to create an awesome pattern

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 project uses the Arduino Duemilanove development board (from www.sparkfun.com) as the basis for the project. Then I used the Arduino Protoshield

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 has a small amount of intelligence (turns on when dark off when light) but not enough! Time for some

Here’s a six word tragedy: My arduino needs four AA batteries. Really? Isn’t this 2012? Where’s my jetpack?!! Here’s a way to the future — a way to make a solar panel, from scratch, that can power any arduino off of sunlight or even light in your house. Sort of a peel-and-stick power source for

So if you are like this Lazy Old Geek, you have a lot of rechargeable batteries lying around. I wrote another Instructable with some battery tips. http://www.instructables.com/id/Rechargeable-Battery-Tips/ Amongst these batteries, I have a lot that no longer work or don’t work very well. So I decided to try to revive them. First step: If the

The circuit presented here can automatically charge a 12V, 7Ah battery, or above. Special features of the charger are as follows. It automatically controls the charging current as per the status of the battery. Battery voltage level as well as charging status are indicated on the LCD display. The charger maintains float voltage, if battery

The device will be live on Indiegogo soon. Arduino, Raspberry Pi and other development boards have gained much attention in the field of electronics and IOT. These boards
Ultimate 6V powering board you will ever need! Continue Reading
AIR Mouse is also called gesture-controlled mouse and it works based on hand gesture. In this project an accelerometer is used for measuring the tilt of hand in X and Y direction and moves the cursor according the tilt. In the project two types of circuit are used, one is the transmitter circuit and other
