Gunchuck – Nunchuck Arduino and a BB-Gun

at 11:26 pm. Filed under Electronic Hacks, Insane Equipment


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 control work to allow him to say fire when the gun should shoot.

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 great applications.

“The NanEye 2B sensor provides a true system on chip camera head with fully self timed readout sequencing, AD conversion to 10 bit and bit serial data transmission over LVDS. AWAIBA’s proprietary data interface technology permits cable length’s up to 2m with out any additional components at the distal end. Due to the low energy dissipation on the interface no complicated shielding is required to meet EMC norms. With it’s 250 x 250 pixels at 3um pitch the sensors provide clear and sharp images with outstanding MTF in a very compact size. A frame rate of 44Fps permit synchronization to any type of display. The NanEye sensor provides delay free, smooth video operation resulting in a safe operation and a clear diagnosis. The sensors are connected to minimal diameter cabling solutions. As an option, a small lens an be assembled to the chip, this option does not increase the total diameter of the sensor, making it the world most compact digital camera.”

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 top of a vibration sensor. Papydoo is waken up by a sufficiently strong vibration. Two eyes are then displayed on the LED matrix, wandering randomly around. After a few seconds with no vibration detected, the eyes close and Papydoo goes back to sleep. Also once in a while (odds: 1/5), a parade of “Space Invaders” is displayed, which bounces up with vibrations. There is a button at the back to manually switch through different modes: Eyes, Space Invaders, Vibration bar graph and batteries voltage. The project runs from 4 AA batteries and draws around 150uA when sleeping, and around 150mA when awake.”

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 broadcast an FM radio signal about 30 feet.”

Diy Solar Tracker using spare parts

at 4:30 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


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 actually uses a remote control that can have time programmed events to send signals to the original remote control box for the antenna motor. It just slowly moves it all day to follow where the sun should be. Nice simple design, I automatically jumped to a solution which was overly complicated.

Watch the video below to see the other panels in his system and how everything is connected. He is using grid tie inverters to allow the power that he is generating to be sold back to the electrical company.

How People Think – Motivation and Inspirational Leadership

at 5:45 am. Filed under Educational


These videos aren’t exactly directly tech related but many of us will have ideas which will require hiring employees to make them come to life. At that stage you will find the information useful.

Inductive Current Sensing

at 10:50 am. Filed under Complex Hacks, Electronic Hacks


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 so if you like it please vote for him.
