Arduino: TKs FFTDuino 4: Color Organ Final Form
I made a couple of circuit boards, including a “color organ shield”, and found an ideal enclosure for the Color Organ. The project is now a stand-alone FFT Color Organ that works from ambient…

6.5 watt portable solar panel for emergencies, backpack camping. Frame was made from acrylic plastic. 6x IXYS SLMD481H12 Individual cell specifications – Vmpp – 6.06v Impp – 178mA Pmpp – 1.081W η – 22%…
I found a wonderful implementation of the Fast Fourier Transform that runs in Arduino code, and since it uses the ATmel’s native ADC commands it can work very fast, actually in realtime, to decompose…
The Imhotep Lite in a box using a solid state John Bedini circuit now instead of a relay. It’s a portable lighting unit ready for camping, the boat or an emergency. It charges internal…
On May 1, my kids ride their scooters down the sidewalk in front of our house, which is slightly inclined, giving them a great ride, just from the power of gravity. I makes me…
In this video I try to show how to repair a sealed leac acid battery. I got this battery from a friend, who used it in a portable Flash lighting unit and he has…
Hi all going on the experiment on the electrolysis, i have created this “thermos ” reactor. So i have inserted the reactor itself in a second bigger jar completely sealed. so i get a…
