It is nice to see the youth of today being inventive. For his science fair Charlie Sobcov designed a plastic film that is in the shape of a falcon. This plastic is tinted with a color that humans can’t see under normal lighting conditions but birds can.

DoctorBass showed is that he can jump start his car using a powerful battery pack that can fit in the palm of your hand. He is also into building Powerful Electric Bikes. This is one impressive battery pack with some wheels bolted to them. 🙂 Have a look at the battery pack specs below! "432 Sony 18650V (known as Konion).used in Makita, Bionx an, 3.75 Volt, Lithium-Ion 2.21 Kilowatt-hour

Here is a nice new shield for the Arduino. This Audio Shield allows you to record and playback audio using the popular Winbond ISD4003 chip. One thing that looks like it was a bit of a pain was having the 3 volt Windbond chip to interface to the 5 volt Arduino. Windbond ISD4003 datasheet (PDF). "The Voice Shield™ (VS) is an analog audio shield for the Arduino that allows
NerdKits has put together a video that describes how a LED row/column matrix is wired. This comes in handy when you have limited pins and need to control lots of items. Another popular method is to use a serial to parallel latch. "This project makes use of row-column addressing, which lets us control lots of LEDs without having one wire going to each one. We also use one
The next phase of the Suzuk-E has been completed , it is focused on the Suzuki Electric Bike Motor Rebuild. The result is a three fold increase in power! “The objective for the purposes of the Suzuk-E project is to lower the no-load RPM of the motor and increase it’s torque. This typically would be accomplished by winding more turns of lighter wire into the same physical space available. In
If you have an iPhone are watching some long video holding it in your hand will get old fast. Here is a quick and easy Pencil and Rubber Band Stand that you can build from some office supplies in a few minutes.
