Wall-E Engagement Ring Box

    We have seen lots of Wall-E designs built by fans of the movie before. Most Wall-E designs have some DIY electronics like the custom Wall-E track build we saw earlier this year. This Wall-E Engagement Ring Box may look similar to some of the DIY projects we have seen in the past with one big exception, it was built for the sole purpose of presenting an engagement ring!

Mini Sumo Robot with no Microcontroller

  This mini sumo robot was developed without using a microcontroller. Using circuits as an alternative to a microcontroller makes its implementation cost efficient since there isn’t much to it. Watch the video to see the machine demonstrated against a stationary object (I guess actual robot testing is the next step). Best of all there is no programmer needed to make a change, just tweak the detection wings a bit

Flying Robots that can Cooperate Autonomously

  The video above demonstrates what Vijay Kumar and his team are building. We have seen some toy quadcopters that have some impressive capabilities but I can’t wait till a tiny and smart quadcopter as agile as these are available. If you don’t have the time to watch the entire video make sure you see the flight demonstrations at 10:05. Thanks for sending this in Matt.  “In his lab at

Name the Thing Contest – 198

    The prize this week is a pair of ESD Tweezers, just what you need to work with those tiny SMD parts. This contest will run for one week (March 4 – 9, 2012). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send an email to contest

Hair Band with LEDs and an Arduino

  Becky Stern from Make magazine shows us how to make a cool hair band with LED lights. If you want to get this hair band for yourself then you can make one by watching this amazing video and follow the steps! “Build a pulse-sensing headband that flashes a heart-shaped LED display to the beating of your heart! Uses a scratchbuilt perfboard Arduino build from Mintduino parts, the Open Heart

Transforming a Hg Lamp into a powerful UV Light Source

  Giorgos Lazaridis from PCBheaven has transformed a discharge mercury gas lamp from his workshop into a powerful UV light source. A UV lamp usually generates UV radiations that cause the internal coating of the surface to glow and produce light. If you have any discharge mercury gas lamp out there in your storage room don’t throw it in the garbage since you can follow Giorgos’s steps for changing it into

Identifying Resistor Values using iPhone’s Camera

  Are you  color blind? Then it would be hard for you to recognize the resistor value while working on projects. Rich Olsan from nothinglabs developed a cool iPhone application for you guys which helps identifying the resistor values through its camera. All you need to do is install application on your iPhone and follow these steps. “Using resistor ID is easy: 1. Take a photo of a 4-band resistor
