The iButton garage-door opener using an Arduino

I've made an iButton garagedoor opener and logger. On a Dutch (kind of) eBay (www.marktplaats.nl) I found some iButtons and readers very cheap. I had no idea what to do with them, but I bought them anyway. My garage opens with a push on a button, so it must be possible to get that working with the iButton. I also found some really cheap (0,50 euro) displays, so it would be nice if I also can make a screen t ...

Arduino Controlled Can Crusher With LCD Readout

I have always wanted to do an instructable, but I never had a somewhat original idea that hasn't been done a million times, or something that had no means of building. I have some friends who recycle aluminum for money and after seeing the large bags of an unknown amount and weight of uncrushed cans, I decided to make a machine that would crush the cans, count the cans, and tell the weight of the number of ...

Bicycle North Indicator using Arduino

Magnetoception is the ability of some animals to detect magnetic fields as a means of orienting themselves.  Although humans do not seem to posses the same biological mechanisms that allow other animals to sense magnetic fields, there are still many ways that we can improve our sense of spatial orientation. This project is an attachment to your bicycle that beeps to let you know that you are moving in the d ...

Precision Fermentation: Arduino-Controlled Crock Pot Yogurt Maker

A homemade thermostat attachment for a crock pot (or other electric heating device). It can be used to precisely control the temperature of the crock pot for things like yogurt fermentation. Why Making yogurt is fun. It is also way cheaper than buying it. You can make yogurt on the stove or in an oven, however it is fairly temperature-sensitive. I am lazy. I don’t like waiting around for the milk to sterili ...

DIY Antique Phone Doorbell using Arduino

Bryan Zimmer emailed us this fantastic retro-themed DIY hack, a most timely submission as we just revisited the noir art deco-science fiction classic Dark City and we think this would have perfectly fit in the world (or in Adama's quarters on BSG). Bryan gives step-by-step instructions of how he converted a 1940's Swedish-made Ericsson bakelite original into a wireless doorbell... This project combines a ba ...

Appliance Remote Control using Arduino

One of the basic tasks in many home automation systems is controlling power to appliances. They could be lights, or a heater, or an exhaust fan, or just about anything else that runs on mains power. The problem of course is that it's dangerous to mess with mains-level power directly and you may even be in breach of your local building code if you don't have the necessary qualifications. This project uses a ...

Cheap Arduino Controled Yogurt Maker

These days I was reading an interesting post on how to make yogurt "by the gallon" (http://www.instructables.com/id/Yogurt-By-The-Gallon/). One thing needed was to maintain a rather constant temperature of 43ºC (110°F), so the bacteria can grow properly. Though you can buy commercial yogurt makers, they aren't big enough for a gallon of yogurt. Besides, it's cheaper (and way more fun) to build one yourself. ...

However, by enslaving robots you can keep your pet happy and enjoy a stress-free holiday. To save money and learn something new, I decided to make my pet feeder out of recycled materials like cardboard and glue sticks. Cardboard is great for rapid prototyping. I have ...
