POWERING STUFF WHEN THERE IS A POWER OUTAGE Imagine everything is off and the output voltage is zero at the beginning. When input is applied correctly, the supply voltage passes through the body diode of the MOSFET raising the output voltage. As the output rises the gate-source voltage of the MOSFET rises through R1-R2 resistors and so Q1 MOSFET turns on. MULTIMETER | ELECTROBOOM Every battery has some internal resistance, and that increases as the battery depletes. While the internal resistance of a car battery can be less than 10 mOhm, the resistance of a AA battery is around 250 mOhm. This means if you draw 2 A from the battery, its voltage drops by 0.5V out of its total 1.5V. So ideally if you short the AA battery INDUCTION HEATER WITH ZVS CIRCUIT Final Circuit.

HOW TO MAKE A TASER (STUN GUN) I make it simple here: a typical transformer is made of two wire windings around the same core (air, metal, ferrite, etc.). When you apply AC voltage on one side, you create magnetic field which passes through both windings. Now changes in magnetic field will move electrons on the secondary and hence create current flow. JUMP START A CAR WITH SUPER CAPACITORS This means the capacitors have 7/460 = 15.2mOhm resistance which is better than expected. As you see from the plots, while the battery could start the car in less than 600mS, the supercaps started the car in closer to 800mS, which means as expected the crank motor is turning slower. But that is good enough to start the car. THE PAIN OF ELECTRICITY (AC VERSUS DC) But you should know that RMS means the effective AC voltage, meaning that from power consumption point of view an AC signal with specific RMS value is equal to the same value DC signal. But the actual peak of the AC voltage is the RMS value times 1.41. So a 6.5V RMS means that it is oscillating around 0V with 9.16V peaks in a sine wave form. WHICH IS THE KILLER, CURRENT OR VOLTAGE? There needs to be an electrical force or pressure, and that is the voltage. Voltage in electronics is the same as pressure in mechanics. So in order for electrons to move, there must be some voltage difference between the two wire ends to push the electrons from one side to the other.

HOW TO MAKE A COIL GUN I think the explanation is a little wrong here. When the switch is pressed (say everything initially 0), the capacitor’s voltage will slowly rise up to V2 (around 3 to 4 seconds based on the values), while the voltage across the 1M to the right of the capacitor will immediately start off at V2 and slowly go down to 0 (this is how any RC circuit would behave in response to DC switching).

CHANGING SIGNALS INTO PULSES, TO DRIVE THE TESLA COIL Posted on December 21, 2018 byMehdi Sadaghdar
32
I designed a circuit so I could make my oneTesla Tesla coil make sounds with my voice: Well as you saw in the video, typical Tesla coils like oneTesla generate sound and music by interrupting the output arcs at a given frequency, usually programmed by a micro controller. If you like to see my videos on oneTesla and how it works, here they are: * How to Solder (OneTesla): https://youtu.be/f2biiEgIsF0 * All you need to know about Tesla Coil: https://youtu.be/Og9j5Wk0Di4 In my case the micro controller was outputting pulses between 14uS to 54uS. The wider the pulses, the longer the arc and so the louder thesound.
So what I did was to replace that signal with my own. I used a regular electrec microphone and fed it into the amplifier circuit I had designed before for my Wireless Lavalier circuit. The circuit I used as amplifier looks like below. See that page for component details. As I found out later, my circuit is susceptible to electromagnetic noise from the Tesla coil output. If you have designed a circuit for consumer use, you would know battling EMI (Electromagnetic Interference) can be a very hard task to do. But SPRINKLE CAPACITORS everywhere you shall be fine, if you are lucky! What I would do is to add capacitors, one parallel to MIC (let’s call it C3) on the board side of the wire to get rid of noise picked by the microphone wire, one parallel to R4 (C4) and another parallel to POT (C5). C4 can be large. For high frequency 100nF could be enough, and if EMI still sucks then maybe another 10nF in parallel to C4. But for C3 and C5 you need to consider the audio frequency and make sure you don’t filter it much and ruin your audio frequency response. For C3 don’t go above 10nF and for C5 no more than 200pF (in case of my circuit, other circuits have different properties). And then I fed the output of the amplifier into the circuit below. Here’s what every component does: * R2 and R3 provide a DC bias of around 1V that the audio input willride on.
* R1 combined to C1 provide signal filtering to prevent high frequency to get in. * POT1 provides a threshold voltage that the audio + DC bias input will be compared to by the U1A comparator. If the input signal is above the threshold, U1A output is high and otherwise low. The closer the POT1 threshold voltage is to the DC bias created by R2 and R3, the more sensitive the circuit becomes, and U1A can trigger on noise ifthey are too close.
* C2 is to filter noises on POT1 threshold voltage. * U1A creates square wave output. * C3 and R4 are a high pass filter and only send out the edges of the C3 input square wave and C3 output always discharges at a fixed rate determined by the time constant RxC. * R5 and R6 create a fixed voltage around 1V filtered by C4, which the pulses are compared to. * U1B cleans up the input pulses into nice looking square pulses. * C5 is to filter noises on the power supply. * The entire circuit is powered from the output of the 5V regulator on the interrupted board. And so below are the waveforms through this circuit. From the top, we have the sinewave input, U1A output, C3 output, and U1B output. Below are the component values:* R1 = 3.3k Ohm
* R2 = R5 = 82k Ohm
* R3 = R6 = 18k Ohm
* C1 = C3 = 100nF
* POT1 = 100kOhm
* C2 = C4 = C5 = 10uF * U1A and U1B are in one chip MCP6562. But any comparator with push-pull output with proper frequency band (over 1MHz) would do. * R4 = 180 Ohm (for around 30uS pulse) You could use a potentiometer to trim as you wish. If EMI is still an issue smaller capacitors like 100nF parallel to the 10uF capacitors should help. Remember each capacitor has an operational bandwidth and won’t filter well above that frequency. The higher the capacitance the lower the functional frequency. That’s why we put smaller capacitors parallel to larger ones, to increase the filtering capability to higher frequencies.
