Kerry Wong shows us a project that allows for accurate Milliohm Measurement. For day to day applications your trusty hand held multimeter will probably do just fine, but when you need to make a very accurate low resistance reading this circuit is sure to help you out. “I used the reference design for the unity-gain difference amplifier AD8276 and a precision Op-Amp AD8603 from Analog Devices to form the precision
A walking robot like MABEL might not look that interesting to many people since humans do it all the time with no effort but when you think of the complexity behind what is being done in the video above you have to admire the machine! Thanks for the tip Fahd Via: Engadget “MABEL runs free for over 110 steps! In our opinion, this is the most realistic, human-like running achieved
This project by Robotics / Electronics / Physical Computing is an Airsoft RC Tank that Tracks the Enemy and Fires at them. Using IR LEDs on a target and a LEGO NXT brain the robotic tank drives around looking for the target. The tank doesn’t hit anything because it has an ultrasonic sensor in the front to sense the distance from objects. A Wiimote camera is used to look for
This would be a good time to hack your Apple TV to use the Couch Surfer Browser since you will then be able to make your Apple TV play HTML 5 Games! Please note that you will need to jailbreak your Apple TV first. Via: Slashgear and TUAW “A hacker installed the Couch Surfer browser on a jailbroken Apple TV and was able to demonstrate an HTML5-based game, Casino BlackJack.
We have seen quite a few Nintendo Nunchuck hacks. The Nunchuck is a great piece of hardware for hackers since it packs lots of great sensors and switches in a nice looking, functional package and best of all they are cheap! The LVL1 Hackerspace decided to use a Nunchuck in a Fire Breathing Pony project that they brought to Maker Faire Detroit. There isn’t much details on the build yet
This DIY Animatronic Eye tutorial by PyroElectro might be just the thing your next Halloween project needs! “This tutorial will present a single method for controlling 2-axis of robotic eye movement using an improvised gimbal system. This will give us control for the animatronic eye to move up and down as well as left and right, just like a human’s eye. Four micro Servo Motors will be used to acuate
I remember before small CNC machines became popular I would see engraving pantograph system in all of the small engraving stores in the mall. They had large letter blocks which could be traced and the result would be a tiny accurate letter engraved onto whatever was under the cutting head. When I first saw the picture of this Electronic Sketching Pantograph by Laura Harris I was wondering what the wires
