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
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
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
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 device which had been used until 70s when it was replaced
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
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 was to create the best place online for learning electronics and making
