Temperature Control For Kitchen Appliances

In this Instructable, I will step through controlling the temperature of most kitchen appliances. As an example, I will use an old Westbend Poppery popcorn maker (aka. coffee roaster), but these same techniques will be applicable to most hot plates, coffee makers, and waffle irons. This instructable puts you at risk of electrocuting or burning yourself. I will do my best to point out potential pitfalls, but ...

Wireless Altoids Display

This Instructable will show you how to modify an Altoids tin for a wireless 2x16 character display. Using an Altoids tin was inspired by the need to have a small yet protective enclosure for a pair of Xbee modules recently bought from Sparkfun. I purchased the Xbee Pro modules with external antenna for the extended range the setup provides (useful for future projects). Then I realised I would need to mount ...

Secret Knock Detecting Door Lock

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 if they give the same knock! (Though this does trigger a lot of false negatives, which is no fun if you're in a hurr ...

I only recently dropped into the project and got to learn a lot about python, plists, and arduino auto-reset functionality. I’m going to share what I’ve learned because I think there are lots of other people out there struggling to make it work. This page doesn’t really offer much that J4mie didn’t alrea ...

It’s been only a couple weeks since I discovered Arduino, an open source microcontroller platform. I was looking for a cheap interface between my laptop and electronic circuits. Arduino with its price $35 and easy to use development environment was the best choice. So after getting my Arduino Duemilanove board and ordering some cheap components from AllElectronics, I had everything to start working on my ol ...

Superb DIY Retro Lighting Design

What is it? It is a decorative lamp; a very, very impractical decorative lamp employing a few vintage display devices and a couple of LEDs too. A friend of mine was one of a group of artists who produced Ascension (the giant origami-crane tent) at the 2010 Coachella Music and Arts Festival. Since he was responsible for the solar power array and system, he asked to borrow a little dekatron spinner of mine to ...
