LIFI – AUDIO TRANSMISSION THROUGH LIGHT

  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...

Rubik’s Cube Solved in 0.38 Seconds

  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...

Circuit Breaker Works in Slow Motion

     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...

Binary Clock Build

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...

Coin Cell Jump Starter Project

  Ted Yapo is designing a crazy project idea, it is a Coin Cell Jump Starter! Just think next time you need to jump start your car you simply need to locate a coin cell and use this system to suck the power out in a usable way to start you car. Is it practical? Not really but it is cool is this theoretical idea would work. It is a total work in progress,...

SMS Message usage with GSM Modem and Arduino

  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...

Water Meter Cloud Monitoring Interface

    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...

Making of a New Nixie Tube

A Nixie Tube is an old piece of technology, Dalibor Farný has resurrected the old technology by working through the techniques to build new tubes by hand. The video shows the tedious process of the low volume creation of them. Lots of complex mechanical steps are needed from spot welding to glass blowing is needed. “The nixie tube is a vintage display...

Food Robots

  We have seen some food robots before. Looks like we might be on the verge where the robots are going to be used for what they are good for such as show in the video where the robot spreads pizza sauce perfectly or can finally pick apples as good as a human. Just as in any industry when simple tasks such as flipping a burger is automated some of these...

Adafruit PCB Manufacturing Line

  The Adafruit PCB Manufacturing Line is quite impressive. Ladyada (Limore Fried) goes through the entire process start to finish describing what each piece in the line does. Questions from the MIT students at the end are interesting also. “Ladyada is the hacker @ Adafruit, founded in 2005 by MIT hacker & engineer Limor “Ladyada” Fried. Her goal...
