hi every one.. im doing a project about... fly zapper... wonder if u guys can help me with that...
have to use 12volts as power supply, two resistor, photo diode, op amp (Lm324N), NPN or PNP transistor, ..
:smile:thanx
Here are two versions of the best clipper circuit I could find in a short search of the radio handbooks I have on my, somewhat limited, book shelf. I was trying to find a fairly simple clipper circuit I could use ahead of a good audio filter to help eliminate static crashes, and the key clicks...
Digital multimeters
Multimeters are designed and mass produced for electronics engineers. Even the simplest and cheapest types may include features which you are not likely to use. Digital meters give an output in numbers, usually on a liquid crystal display.
The diagram below shows a switched...
[edit] Resolution
The resolution of a multimeter is often specified in "digits" of resolution. The use of a digit count dates back to the 1970s when multimeter vendors were very proud of how many digits their products could display (this was important, because readout displays were costly). The...
A multimeter or a multitester is an electronic measuring instrument that combines several functions in one unit. The most basic instruments include an ammeter, voltmeter, and ohmmeter. Analog multimeters are sometimes referred to as "volt-ohm-meters", abbreviated VOM. Digital multimeters are...

سلام. روش شما کاملا درسته + مطلبه خيلی جالبی بود اما دقيق نبود
(با پوزش) به نظر من روشه آسون تر اينکه از فرمول zer استفاده بشه تا به ما بگه چه مقدار لامپ احتياج داريم برای هر متر مربع.دوباره ممنون از مطلبتون
N=\frac {E*A} {F*K*LLF*UF}
N= number of fittings required
E= sermis...
