Balloon Experiments with Amateur Radio- Launch 4

  Sending a balloon into near space has been done quite a few times by the BEAR group in Alberta Canada. Have a look at the details of their 4th launch where Tomoya Kamiko from Japan came to Canada with his HD camera to take it into space! "The balloon and camera were launched at 7:44 AM, the balloon burst at 10:51 AM at 107,145 ft. and the camera landed

Ignite talk - Adapting with Technology

  Mark Argo put on a great Ignite talk at Ignite Toronto about our DIY environment. "Since the dawn of humanity we have fashioned objects to help extend our basic capabilities: see better, walk farther, speak louder, soar higher. More than ever we depend on these ‘gadgets’ to navigate our environment and culture. ‘Adapting With Technology’ explores the origins of modern gadgetry and looks towards their future role as personal

USB to RS232 Adapter Hack

  Openschemes shows us how those $10 USB to RS232 adapters can be hacked to provide us a valuable tool. Nice thing about soldering some wires to a few test points on a finished circuit is that the circuit can be put away for use in the future. That never happens to a circuit that was built on a bread board since it will probably be ripped out to make

Arduino GPS Game

  This Arduino GPS Game that won the Let Arduino Play contest over at Brico Geek looks like fun. Unlike normal games where you simply interact within the imaginary game space this one uses GPS to bring the game play into the real world. If someone would like to provide a few sentences that describe the game a bit better I would love to publish that. 🙂 ADDED Sept 23

Micro LED Controller - Light Chaser

  Before you say this LED Controller doesn’t look micro, have a look at the board in the picture below with a 9 volt battery snap to compare it to. This board is tiny! You could hide this thing in model cars, train sets, props, this list goes on an on. Also the interface is a single button, it doesn’t get much simpler than that. 🙂 Via: HG Forum

Dice Reading using an Arduino

  Steve Hoefer has completed version 2 of his Dice Reading project (Version 1 can be found here). I was surprised to see that only 5 locations of the dice are looked at to determine what number is present since there are actually nine locations where the pips could be located. It obviously works but for some reason isn’t obvious to me at this moment!  "This version uses 5 IR

Name the Thing Contest - 101

Thanks to the Ohm’s Law Calculator Website for sponsoring the contest this week. They will be providing a useful Resistor Color Chart Mug to the winner. The site provides an Ohm’s Law Calculator, Ohm’s Law Wheel, E24 Resistor Sizes, Resistor Color Chart, LED Resistor Calculator, AWG Wire Sizes and mcd to Lumens Converterinformation. This site is sure to be useful when you are designing your next circuit, might even be
