Everyone has USB gadgets.  It’s pretty much a fact of life.  Another fact of life is that these USB gadgets also continually run out of power when you most need them.  No need to fear, solar power is here!  Ditch those crazy wall adaptors, throw out the laptop, and start making your own solar charger!

This circuit will take a light reading then display a number between zero and 99. Step 1: Parts you will need Major Components in Project To make the 0-99 LED display you will need… ~ photo resister ~ Arduino ~ 9 different wires ~ 2 seven segment led displays ~ bread board ~ staples ~ […]

So we’re always cooking up hot new hardware in the Grav Corp labs. Recently, we’ve been working on a project using a 128×64 OLED screen with the SSD1306 controller. Adafruit is a good source of these displays, with an excellent library written by Limor Fried. The Adafruit_SSD1306 library makes it simple to use these displays with […]

Combine three inexpensive LED matrix display panels, an Ardweeny microcontroller and a standard PS/2 computer keyboard into your own go-anywhere, instantly updatable 768-pixel digital message board. The code can hold up to six lines of text with a maximum of 100 characters each. Pressing a key on the keyboard gets you to input mode. Use […]

I’ve reached the point where I need to think how I’m going to control the motor & linear actuator for my solar tracker. Things to consider – Must be able to go forwards and backwards – so that makes 4 channels, 2 for each motor. Must be able to provide enough power to drive the […]

This is my Magical Music Box which converts music into a light show. When i was daydreaming what to make for my final project, i wanted something that would make a light show for any song simply by hearing it. Materials used: 1x arduino 8x 1k ohm resistors 5x 10k ohm 7x 560 ohm 3x […]

This is an instructable for the Interactive LED Lab Coats, showcased at Autodesk University. Check out the videos below! The first is a demo of the colors actuated by the buttons. The second is a demo of the breathalyzer! (this will be explained later) Tools  Sewing machine Soldering iron Wire cutters & strippers Hobby knife […]

A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in ATmega644 microcontroller, and pin headers for plugging in a ESP-01 through-hole WiFI module. Shortly after that, I discovered the Lua firmware […]

This is the 1st part of a series of 3 posts on the new ESP8266 microcontroller I only talk about a bare handful of new boards because most of them don’t pass my test: whether they’ll let me do something today that I couldn’t do yesterday. But every once in a while a new board, or a chip, comes along that […]

Introduction My project is about providing multiple saved cartoon sounds then do funny effect on them through controlling the speed of play either faster or slower. it contains 4 sound files:   Crazy Frog, Bird is the Word “by Family Guy”, oompa loompa “by Willy Wonka movie”, and a guitar chord to give one of […]
