Xellers shows us how to build a DIY Spark Gap Tesla Coil in this Instructable. When you are done looking at the Tesla Coil have a look at the DIY CRT he built! “Shoot foot-long bolts of lighting through the air, light fluorescent tubes without wires, and power your other high voltage experiments with the aid of this tabletop-sized Tesla coil! The key to this coil’s performance on such a
Our friend Pete Mills sent in his latest project, it’s a DIY Guitar Pickup Winder. There have been quite a few DIY Winders build before but this one automates quite a lot of the steps. “Here is a feature list: -Pickup Winding with turn counting, RPM, ETA and auto stop -Stroboscopic guitar tuner -Ohm meter for coil resistance measurement -Gaussmeter for measuring polarity and magnetic flux density of pole pieces
Koen has just completed his 8X8X8 LED Cube which is powered by an Arduino. This is a really impressive looking build! “I finished my latest project. I wanted to build a led cube. It had to be big (8x8x8) and easy to build! I found a way to do it! 32 meter of stainless steel, 128 meter of wire ,8 meters of heat shrink, 8 max7219 chips later. It all
Malte Ahlers from Germany sent in this great Microsoft Kinect controlled Delta Robot (translated to English). We have seen quite a few Kinect hacks recently but this one represents something that interfaces very well with an external device like we have seen in the past with quite a few Wiimote Hacks. “I built a delta robot and tried to control it with the Microsoft Kinect sensor. My aim was to
The LM35 Temperature Sensor is a versatile and inexpensive sensor that could be useful in many projects such as a PWM Fan Controller or this LCD Thermometer project. In this case a ATMega8 reads the analog value and updates the LCD to show the current temperature. The code is provided so you can build from this example. “In the circuit the LM35 is connected to the ADC port of the
Annie (Wei) Dai from Cornell University sent in this Vowel Voice Decoder System she did for the ECE 4760 Class. “The audio input is sampled through a microphone/amplifier circuit and analyzed in real time using the Mega644 MCU. The user can record and analyze his/her speech using both hardware buttons and custom commands through PuTTY. In addition, the final product also supports a simple voice password system where the user
We saw a project earlier this month that worked like an Ambilight system but this open source Light-Pack USB Ambient Lighting System seems to have much better effects. And since it’s open source you can get all of the info you need to make your own. I can’t wait till there is a system that doesn’t requite a computer to process the image. “The software analyses the image on your
