Calculating pi with a Pendulum
Pi is a very interesting number that comes up in many formulas. Did you know that you can calculate it using a swinging pendulum?

Colour Injector – Arduino Mixing Colour Lamp
This is a great looking lamp that allows the users to interact with the lamp colour in an interesting way. “Colour injector is an interactive multi-coloured lamp designed as a physical expression of the way red, green and blue light are used in digital interfaces to create a full spectrum of different hues. Syringes suspended below the lamp are connected to another set inside the body using clear tubes
Car Instrument Cluster Clock using CAN Bus
Instrument clusters are no longer truly mechanical analog gauges connected to sensors directly in your car. The car is a big sensor network which communicates to the dash board instruments. This means that you can re-purpose them like Esko Haas has done with his 2003 Fiat Stilo closk. If you want to build on his work you can find his code here. “By the way, I’m using this board for connecting: http://www.ittgroup.ee/en/mikrokontrollerite-arendusplaadid/545-avr-tlcd-128can.html It’s compatible
POV Hard Disk Drive Clock
Using an old hard drive, some 1 watt LEDs, a complete redesign of the hard drive motor drive circuit and an Arduino Marcin Gosiewski (damago1) has built a great looking clock. The display is nice and compact since he is using a 3.5 inch hard drive as his base. “The project involves controlling HDD motor (3 wire brushless dc electric type BLDC) using open loop control without feedback, and using back
