This LC Meter was built using a Microchip PIC 16F628A. It would make life a bit easier when attempting to identify a few of those components that are always left over on the desk after building a project. Mine are often dumped into a miscellaneous box with other various components which makes it even more difficult to identify later… I think this meter would make a great addition to my
My daughter Alexis and I worked on this Karate Chop project as an entry into the Avnet Dog Days Summer Contest. She had the idea to make a game to enter in the entertainment section of the contest. The game she came up with was a reaction game where you have to quickly move to the correct indicated position. Four infrared detection circuits was the resulting method used to detect
It seems that you can build anything with LEGO, this LEGO Pan Tilt System built by James Catan sure demonstrates that. Sure this could have been built from metal brackets held together with nuts and bolts but it would take 10 times as long and be just as functional. I am now wondering if I need to add a box of LEGO to my workshop? Watch the first video to
If you like to get woken up with a bang this Bomb Clock is for you! Watch the video below to see what happens when you don’t defuse it correctly. This will be available as a kit soon, I can just imagine the hack to come which includes a small fire cracker to signal a failure to defuse the clock.

I have built a few speaker enclosures over the years. Mostly sub boxes that are made from square cuts of MDF on the table saw. A bit of handy work with a jigsaw and a drill usually results in a speaker box that is functional but definitely doesn’t look as good as a store bought speaker cabinet. This DIY 2-Way Loudspeaker that Adam McCall built isn’t a budget build since
This Portable Car Alternator Charging System from The Back Shed solves quite a few problems when it comes to portable power. If you have a dead battery and no plug close by to charge it what do you do? Get a boost is one option but if you would like to be self reliant this alternator charging system is a cool idea. It uses a small gas motor to turn
Check out this RGB Viking Helmet with LED Mohawk. If you are looking for some attention this is guaranteed to get it. It uses OctoBrite LED boards to make the magic happen Via: Build Lounge “The control box was a pain, but such things usually are. There was barely enough room for the parts and wires I was using…and it turned out that the electret amp was picking up too
