This idea is an excellent way to control the temperature of your home appliances to make things like a wine refrigerator fermenter. Mikey Sklar from screwdecaf has developed a project named YACT 2 which controls the temperature of most home appliances by using a precise temperature probe and relay to apply power to the appliance when needed. You can watch the video below to see the system in action. Mikey
Kevin Martin and Hyundo Reiner from Cornell University made this Automatic Grapefruit Segmenter for their ECE 4760 Designing with Microcontrollers Final Projects. Watch the video below to see it in operation, the system first rotates the half grapefruit looking for the thick material that divides the segments. This is done by reading the feedback from a flex sensor. Once the entire half grapefruit segment locations have been mapped the
Want a mouse that doesn’t look like the normal soap bar shape? Have a look at these Cool looking Computer Mice. David Allen from Zedomax has a great round up of these innovative mice. “Where would we be without the mouse? Well everything would be slower and as for cut and paste, well forget it! Yet we seem to take the mouse for granted, just imagine life without it
 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!
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
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. Â “In his lab at
 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
