If the balloon is spinning, John is probably right.
15 x 2 would use 17 pins.
6 x 5 would use 11 pins.
If you don't need any amplification, why do you need any circuit at all?
Maybe it is time to tell us where this signal is coming from and where...
An op amp. @Bordodynov's circuit is nearly as complex as a basic op amp.
The reason op amps work so well is that they use very high gain and a...
You won't do that with a single transistor. Use a friggin' op amp, despite what you learned on someone's youtube video.
Or a hall effect switch and magnet.
AC is easier because transistor amplifiers need a bias voltage to operate. You just stick capacitors at the input and output, and this removes...
You can make a decent small signal AC amplifier with one transistor. But a DC amplifier is an entirely different thing.
Wll, not in DIP IC's anyway :)
As an aside, if the battery is 8.1V and the device is drawing 1.3A and the LED is 3.5V at 1.45A, the the efficiency is:
1.45 * 3.5 / 1.3 * 8.1 =...
I propose the deductor. It is a logic element that can deduce what you are trying to do and do the right thing.
Your term EM field is contradictory. If you really mean field, there is no electric field component, so it is a magnetic field. If really you...
What is a monopolar field? Last I looked, magnetic monopoles are a theoretical object that has not been found in nature.
No, actually. General relativity is not compatible with quantum mechanics. Trying to fix this is one of the most active areas of theoretical...
Really? What is this then:...
