.. input capacitors, or approximately 2 nF) of the Q 1 oscillator determine the frequency of the search oscillator. In this design, the frequency is approximately 370 kHz. For years, this frequency has prevailed in metal detectors, because ...
.. set-up of an antenna. Placing an antenna in a close proximity of a large metal object helps generate additional power. The wire of an antenna should be more than 150 feet long, which has to be placed horizontally on a higher platform to ... .. µF/25 V electrolytic Improving the free energy device The following more comprehensive free energy deriving circuit design was forwarded to me by one of interested readers of this blog Mr. Prashanth Dhonde (Figure 2). Figure 2. ...
.. of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power. It integrates an LM317 positive regulator with a simple 8-bit ...
.. uncomplicated, inexpensive, and fairly fast (1 MHz), low power voltage to frequency converter (VFC) “Voltage inverter design idea transmogrifies into a 1 MHz VFC” ( Ref. 2 ). See Figure 2. Figure 2. Modified voltage inverter ...
.. 3 , R 4 , C 1 , C 2 , and C 3 , forms a band-pass filter that sets the oscillator’s resonant frequency to 2 kHz. The design uses a Wien bridge with values R, C, R/2, and 2C because it the oscillator needs an inverting gain of 1. ...
.. hotter than the others, its gain increases, and it takes more current and gets even hotter until it self-destructs. This Design Idea shows how you can avoid this problem for pulsed-current-mirror applications. Figure 1. A pulsed-current ...
.. that I was working on. I found lots of ideas on the internet, but they all lacked in one area or another, so I decided to design one. The following lays out my easy-to-build ultrasonic mist maker. It works fine and is, by far, the easiest ...
