Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even […]

You are building a soil temperature sensor. We need a waterproof thermometer that we can burry in the soil. The sensor is made up of a small circuit enclosed in a piece of heat shrink (to waterproof it). Supplies: (see the parts page) an LM335 temperature sensor a 33K and a 56K resistor a short

Finally! It’s been about 3 months since my last Arduino tutorial – I’ve been keeping busy as usual. I’ve been working on this one for some time. I got the parts months ago, made an outline a few weeks ago, prototyped the circuits and wrote the code last week, and did the filming over the

The one wire Digital Temperature Sensor – DS18B20 from Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy. The most recent version of this library can be found at http://www.milesburton.com/?title=Dallas_Temperature_Control_Library We used version 3.6.0

Multipurpose like a traffic light, this one keeps you warm and blinks to make you more visible in the night. Stop traffic with this fun scarf worn around your neck. Repurpose a dollar-store bicycle safety flasher to embed in the scarf. Simulates the light changing pattern and does other fancy sequences. No arduino needed. The

Soldering SMD components isn’t as hard as you might think. In fact it’s easy. If you follow this instructables you’ll soon see just what great results you can obtain at home using just a hotplate. It’s not just being able to make small circuit boards that makes SMT soldering so good it’s also a nicer

3D AIR mouse | Arduino + Processing I’m an Industrial design student, and last year as part of a course called “Technology as RAW materiel” I built this project as my final work. I work most of the time with SolidWorks, a CAD software for design and engenering. Rotating a solid body on the screen

This is a project that was inspired by Marc de Vinck’s Kitty Twitty Cat Toy http://makezine.com/22/kittytwitty/ . It incorporates an RFID reader and the BlinkM, a programable RGB LED. The lamp tweets random colored poems when it detects one of the three RFID cards which each represent one of the primary colors of light. These

Introduction Disclaimer: I am not an expert in any of this. There is lots of information online regarding such designs. Although this setup worked for me, do not trust any of my calculations. Please work all this out for yourself and consult many other sources, or it may spontaneously burst into flames. The contraption is

What it is… Type: Graphical (128×64) monochrome LCD with LED backlight Interface: Serial / SPI This is a good time to read the datasheet Available from: Adafruit, of course! Introduction: This mini-tutorial will go through the process of setting up a ST7565 LCD. These LCDs are graphical which means they can display pixels, not just
