In this tutorial you can make an RFID access system. It’s very simple and can be used with a wide variety of end-uses. Updated 18/03/2013 The purpose of this project is to prototype a basic RFID access system. Although it is not that complicated, this article is my response to a kit reviewed in the Australian “Silicon […]
Time for something different – a single button combination lock. Allow me to explain… Updated 18/03/2013 Normally a combination lock would require the entry of a series of unique numbers in order to unlock something or start an action. For example: A more contemporary type of lock could be controlled electronically, for example by a […]
Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor, an Arduino-style board and some other hardware – to make a device that receives a four-number code which is made up of the distance between a hand […]
Drifter is based on a cheap RC toy car I found at Toys’r’us, named ‘Fast lane Monster Drift’. I think it’s the same model Frits has been used in an episode of TLIHR. It doesn’t work well, you get what you pay for. But it is a good hacking platform. There is no much space left for […]
Introduction Time for another instalment in my highly-irregular series of irregular clock projects. In this we have “Clock Four” – a scrolling text clock. After examining some Freetronics Dot Matrix Displays in the stock, it occurred to me that it would be neat to display the time as it was spoken (or close to it) […]
Recently a family member had his furnace fail while he was away from his house for a long period of time in the winter. His pipes burst and caused quite the mess. This project describes a temperature sensor that broadcasts the temperature in his house to the pachube data logging website. This allows him to check on […]
Following the instructable here, I was able to turn an old digital camera into a time lapse camera using an arduino, a relay, and an open source software program called makeAVI (windows). To modify the camera I disassembled the camera cover and removed the button that activates the shutter. It is difficult to tell from the […]
This is a basic example how arduino works. In this arduino projects you’ll see how arduino control LED on for 1 second and off for 1 second repeatedly. Instruction; 1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13. Upload this code to your […]
This is a project I’m calling Tacit. No, I didn’t bother making an awkward backronym for it, it just seemed like an appropriate name that’s a lot shorter (though less descriptive) than “Hand-Mounted Haptic Feedback Sonar Obstacle Avoidance Asstance Device”. It measures the distance to things and translates that into pressure on the wrist. It’s wrist mounted and senses objects from […]
Update: I’ll add some clarifications after reading comments on various forums. It doesn’t need a 70Mhz ARM CPU, all it does is shift bits into a shift register, that’d be a total waste. There aren’t 16 CPU’s. the slices are designed to be either slave or master, just one ATMega328P chip, they’re chained together, each […]
