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
The US President Obama has one sweet ride that is guaranteed to let him safely ride in style. There are still lots of details that have not been released but from what we know and can see it is one amazing vehicle. This Cadillac is made by GM but it is not based on the Cadillac, it is actually based on the huge Topkick truck! The 8 inch doors
This Household AC Power Monitor idea is similar to what I have wanted to do for years. Jason Winters has taken two clamp meters and connected them to both phases of his house electrical panel. This allows him to monitor the entire electrical usage of his house. He is collecting data and creating a spreadsheet to monitor usage over time. What I was thinking of doing was to install
Stephane Melancon (DoctorBass) sent in a very compact battery pack that he uses to jumpstart his car. There are lots of systems that can be purchased that can produce the same results however none of them can fit into your jacket pocket! "In this video i finally decided to show you how IMPRESSIVE are these A123 cells. During the test, when the starter ran for about 2-3sec, the current
We have all seen the amazing Tesla, it is a beautiful electric car that has some huge off the line power. When I first saw the Tango I thought it was s joke, but on second glance this Tango has some surprising power hiding under that strange body style. This car is half the size of a normal car but has faster acceleration than the Tesla roadster! Even though
We had a number of beehives on our farm years ago. Monitoring the health of the hives was a big job and when neglected could spell disaster. This Beehive Monitoring System could mean the end of that problem. Have a look below for a short list of system features. "This project provides a means to monitor honeybee health parameters in a hive, to allow efficient bee management and research
Since this Electric Trike was a school project there were lots of cool tools that were are the disposal of Smegger. By the looks of it the electronics and motors are top notch. Video after the jump. "- I used two 12v 32amp batteries – A 75amp 24V speed controller made by 4QD in England- quite pricey but really reliable – 5 LED battery condition meter – Plunger pot
