You can build this DSLR Camera old Flash Adapter for a few dollars and still use your old trusty camera flashes on your new gear. Looks like a nice simple and robust circuit. "This instructable shows you how to make a really easy and simple circuit, that protects your new camera from high trigger voltages in old flashes. It is completely safe and will not damage the cameras circuits!
Matthieu Deru and Simon Bergweiler from the German Research Center have put together an impressive hack that allows you to Fly in Google Earth using the Wii Balance Board "After hours of testing and C# coding, you can now use your Wii Balance Board as a new input device."
I love the look of the old fashioned Box Simpson Meters. Have a look at this project that turns three meters into a functional clock! If that wasn’t enough it even synchronizes its time using NTP. "Each meter driver is a single opamp used to sum two signals, scale them and output the result to the meter. One signal is a voltage set between -12V and +12V (actually less
This Turbine Jet-Boat is one fast ride. Looks like 1370 horse power is just enough for a wild water ski ride that you won’t forget. "The T58-GE-8F turbine that is going in Squirt 2. It weighs 350 lbs and produces 1,370 hp @ 6000 rpm. That’s about 1,200lbs-ft of torque! The hull shown in the photos below is a 21ft aluminum white water race boat built by Eagle Power
Ahmad Masri has used an inexpensive ethernet chip called the WIZ5100 to create a simple but flexible ethernet based security system. The low cost of the ethernet chip makes connecting projects to computers or other microcontroller based devices very appealing. "I have constructed a TCP based security system using the Ethernet module offered within the contest , an ATmega16L microcontroller , a PIR as a sensor and few other
This Montegiro Lusso Turntable is something else! I love the style, I think this recreating this concept would make for a great DIY project. "This creation from Germany exemplifies that vinyl is still alive. Targeting audio excellence, it features three height adaptable connected cones developed via alternate layers of aluminum and black acrylic. Whilst its one cone is supported by a lately developed ultra precise synchronous motor, the other
I have been thinking about some green ways of depending on the grid as much as I do. There are so many things that can be done but most are very expensive unless you use some build some of it yourself. Have a look at this solar and wind system that uses some home made sun tracking units. "The systems tracks the Sun using a controller from Red Rock
