Parallel-controlled circuits operate as self-controlled, variable resistors, connected in parallel to the load impedance (parallel loads). They react extremely fast and also control immediately pulses and very short mains break-downs, resulting from strong loads....
“My hobby has been a present occupation as it is because I liked electronics relatings since I was little. Railroad, anime, comic and TV game as well. As for programming in the hobby, because...
This is dual 555 multivibrator like power oscillator. This is my contraption and conception but couple of decades old. It appears to have errors. It worked but the document fixing after design worked, not...

A Low cost A/D with a Potential of 5KV Isolation from Computing elements by use of Normal/Special Opto-Couplers. This can give better resolution and accuracy than a 8 bit A/D. may be close to...
The only way to improve the reception of FM-signals or particularly of stereo FM-signals under disadvantageous receiving conditions is to amplify the antenna signal. This should be made directly at the antenna, since the...
PCB Thermal Design Care for Analog Circuit Stability – If you have a hot power chip near a DC analog circuit, the values will drift, take time to stabilize, this happens even if you...
I was enlightened about this Battery Less wonder. This is a boon for rural areas and an emergency tool which depend only on your will and your tendons. I found this bright flash of...
