My Arduino RGB light's gone through some major changes. Now, instead of just blinking each light on and off, it fades smoothly through the spectrum. The three separate bulbs have been replaced with one combination RGB LED, freeing up the others for other projects. A potentiometer is used to...

I made this little noisebox at a DIYmakeaway workshop put on by the Swiss Mechatronic Arts Society (http://www.mechatronicart.ch/diymakeaway/). I plan to add more to it, eventually, but for now it is just two oscillators being blended together. Both square-waves, with one having pitch-control...

The horizontal position potentiometer acts weird and it is not fault of bad capacitors, because the problem occurs since I bought the new 8liners chassis and installed it to my 25" Hantarex Polo tube. I have problems with centering the picture in horizontal position. The second issue: after few...

Here you see/hear an audio tube pre amplifier with a ECC83 12AX7 or CV492. The tube is a double triode, I use only half of the tube. In fact I am "amplifying" from line level (0,8-1 V AC) to line level, the schematic is only ment to create the typical tube sound. The signal is amplified to...

watch in HD. I took crob227's advice and put a high voltage transformer primary in series with the cathode. I will try out his circuit in the future. This is a reaction I get at approximately no greater than 480 watts of input power. The whole reaction is centered around the voltage drop...

My brother and I hacked a cheap toy keyboard and short circuited an existing connection with a toggle switch and a potentiometer in between. We drilled holes in the right of the keyboard, which is where you see the switches. The potentiometer(knob) acts not only as a pitchbend, but it creates...
