Instructables member Adamu25 made a great lookingDaft Punk LED Helmet Project for a festival held on the Isle of Wight in the UK called Bestival. He has documented the build so you could build your own. The LEDs that you see in the face mask are light strips that are meant to be used on cars. No matter where they were supposed to be used they sure look right at
Gagan jain has built an interesting rig called the LIFI, it allows a simple transmission of audio using an LED for sending the audio signal and a solar cell to receive it. “The full form of LiFi is Light Fidelity. LiFi basically is a Wireless Communication Technology which uses Visible Light for Data transmission. LiFi is designed to use LED Light Bulbs similar to those present in our homes and
Some people are able to solve a Rubik’s Cube very quickly, there are even lots of robots that can solve them much faster than people can. Well this new system is crazy fast. Less then a half second to solve the cube. The motors need to be very strong and fast to push the system to this speed. This means that the moves have to be exacting or else
 We have done a teardown of a 100 amp breaker in the past but it is really interesting to see how they operate in slow motion. Warped Perception has taken a common 15 amp breaker and filmed the 2 states in slow motion. Breakers trip with a slow overload condition which takes a bit of time and a short circuit where the circuit breaker trips almost immediately.
This Binary Clock Build project by JD is enclosed in a custom acrylic enclosure. 3 buttons are used to adjust the time, the binary clock is displayed for your leet friends. For the regular folk there is also a time display on the LCD. The System is powered by a Parallax Popeller. With 40 pins the Propeller has enough pins to drive each LED direct, the buttons are also all
iforce2d has a great demonstration of how to play with SMS Message usage with GSM Modem and Arduino. He goes through lots of interesting AT commands that do the actual transmission and read of the SMS messages. I can think of lots of useful uses of this type of device since an SMS message can be long enough to pack some interesting data chunks such as temperature issues (low temp
In some areas water meters have methods of connecting external monitoring equipment to determine water usage over time. This is normally done by a switch that pulses after a certain amount of water consumption. This was the case for sfrwmaker. He has a water meter that has an internal reed switch which closes once per revolution of the last metering wheel of his water meter. He has created a Water
