It’s just a matter of time before you spill some liquid into your computer keyboard or it naturally gets full of dust and dirt. When this happens keys can stick or may become intermittent. Keyboards are priced to be disposable but that doesn’t mean you should just toss it and buy a new one. Chances are you can take it apart and clean it out. The process should take about
Fellow Canadian Rick Crammond demonstrates how effective shielding is using a fun demonstration. Have you ever stripped some shielded cable and found the foil wrapped around the wires or looked in some electronic gear and seen some some copper paint on the inside of the cover and wondered how effective it is? Well this demonstration shows you that a bit of thin metal can really do some amazing shielding.
Have a look at the Dune Bug E project. Looks like the warm weather kicked the build into high gear! You know you are dealing with some serious power when you need to cut your cables with bolt cutters and solder on lugs with a blow torch. 🙂 “At this point the Dune Bug-E is up & running, and has had 8 or 9 test drivers without any issues ie;
The prize this week is one of my Electronic Component Coaster Sets, these make a great addition to any coffee table. This contest will run for one week (May 8- 14, 2010) . Ending time is based on central standard time. To enter, identify the item pictured above and give an example of what can be done with it. Please do not give the answer in the comments. Send an
The new batch of Cornell University ECE 4760 Final Project are in! There are tons of cool projects as usual, everything from Human Tetris to this MIDI Glove Controller project by Anson Dorsey, Eric Gunther and Jonathon Smythe. The project is based around an Atmel Mega644 microcontroller which has lots of processing capability and all of the projects are developed in WINAVR/GCC. Since the system is outputting MIDI you are
If you need to do some temperature monitoring over a long period of time this is the device for you. It can store 32 thousand measurements and has a current draw of only 50uA. The top picture is version 1 and below is a shot of the surface mount version 2. Via: Electronics Lab “The PIC software is written in assembler and based on earlier projects using I2C interfaces. The
So you think your meter is tough do you? Dave Jones of the EEVblog took a few cheap and a few high quality meters and subjected them to some high energy discharges. If may have seen a component let out its magic smoke but it is something else to see a meter literally blow apart. This destruction is all thanks to a machine that Doug Ford built.
