Our friend Gio from DIY Audio Projects has sent in a cool Push-Pull Tube Amp Build. This tube amp fits into a 8 X 12 inch chassis and looks fantastic! Now if only we could find a drugstore with a tube tester. With cool equipment like this and tube TV troubleshooting guides popping up there is sure to be demand for tube testers once again? "The basic design has
Surface mount rework stations are very expensive, Openschemes shows us that it is possible to perform Surface Mount Component Removal using a Heat Gun. "Now it doesn’t matter much WHICH heat gun you use, although it should be able to produce a good bit of air at >300C. In our experience, long heating times due to using a weaker gun are the biggest cause of PCB burn, bulge, or
A Nerdkit microcontroller is used in this Capacitive Touch Sensor Halloween Pumpkin for some great effects! Full details are provided so that you can add this cool effect to your own projects. The sensor components are just aluminum foil which is great since you probably have some in your kitchen cupboard. Thanks Humberto. "Capacitive proximity sensors work because people are mostly water, and water is a very polar molecule,
This GPS Hunt Project is very interesting, the box is electronically locked and the only way to open it (without using the emergency backdoor) is to go to a certain location. It gives lets you know how far from the target location you are each time the button is pressed but you only have 50 presses to figure it out. Thanks for the tip Jim. "Major components 1 Arduino
You might remember Michael Saunby, he was the guy that had the interesting clock that we were trying to determine heritage for. The clock was almost featured on Antiques Roadshow but unfortunately was left on the cutting room floor. Michael works with lots of antique electronics and this 1930 vintage amplifier and speaker is a great example of what can be done with a mix of old and new.
Need to get into a tricky lock, why not make a lock pick out of one of your old hard drives? That is what the guys over at sorgonet.com did.
Not your typical player piano where the piano automatically plays a nice tune. This creation plays many notes simultaneously to simulate spoken words. What would be impressive is if a person could achieve the same effect using only his fingers. Via: Anything and Everything
