Gunchuck - Nunchuck Arduino and a BB-Gun

Have a look at the Gunchuck, it comprises of a Nunchuck, an Arduino and a BB-Gun. This would be lots of fun if the gun was changed out with a super soaker and mounted on the peak of your roof. You could use a Web cam to watch the dot at night and terrorize the kids that might be out past their bedtime. I think Quicksilverhacks should use his voice

Tiny Awaiba NanEye Camera

Wow camera technology is getting small! When attaching the wires to the camera is one of the main challenges you know you are dealing with something that is very small. These cameras are build using VSLI production just like chips are made. Awaiba has been working on perfecting this camera for a long time, it is best suited for the medical field but I can think of lots of other

Vibration Sensing using a Tweeter

Fellow Canadian Laurence White from Electro-MCU-Stuff has built a neat looking project which uses a piezoelectric element from a tweeter to detect vibrations. He is using a Zilog eZ8 series microcontroller which breaks the Atmel, Microchip or TI norm for the projects we have seen around. I remember Zilog seemed to be very popular years ago but in recent years I haven’t heard much from them. “The enclosure sits on

Micro FM Transmitter

Sean Michael Ragan from Make built this Micro FM Transmitter. If you are looking to get some audio onto the radio over a short distance this project could be for you. The copper layer of the board looks very cool. “This circuit is commonly credited to Japanese multimedia artist Tetsuo Kogawa. It takes audio input through a 1/4″ phono jack and, constructed as shown, without the optional antenna connections, will

Diy Solar Tracker using spare parts

This solar tracking system uses an antenna motor which is normally used to spin an old school roof mounted antenna around. The structure is home made from some satellite dish parts and unistrut as the main frame of the solar panels. I was expecting to see several light sensors and some circuitry to see where the sun was and constantly follow it like we have seen before. But fanman1981 actually

Inductive Current Sensing

How do you detect the actual current from your 22,500uF, 450VDC capacitor bank when you pulse discharge it? Well Norman from Procrastinatus shows us his method. Inductive Current Sensing is done using a Rogowski coil which is wrapped around the high current output of the capacitor bank. A DSO is used to capture the data so the short event can be analyzed. Norman entered this into the Tektronix scope competition
