## Caution! Dangerous! High voltage! Observe the safety rules!

**Part one is the circuit of the generator.**
To get a high voltage, I suggest using a car ignition coil, from the ignition contact system. Other coils do not fit, for them you need to use a different control. The main idea of ​​the scheme is simplicity.
The generator circuit is described below.

To start the coil, we need to apply electrical impulses to the primary winding. For this I suggest using a cooler from the computer cooling system. A cooler is needed in which the hall sensor is installed. Such a cooler has three or four outputs. Conclusions as a rule have the following sequence. "-", "+", the hall sensor. "-" is usually black. In my case, the "+" is yellow and the hall sensor is green. Important! In order not to solder the transistor, the connector from the cooler perfectly fits as a mounting place for the transistor, so do not throw it away. When the cooler motor rotates, the hall sensor will generate periodic pulses when the magnet poles are changed. But this signal will not be enough to pump our coil. To increase it, we use the N-channel mosfet. The transistor will increase the signal to the required operating voltage of 12V. In fact, it is said that the signal increases. But the signal applied to the control electrode of the transistor and the signal output from the transistor have completely different origins. They are bound only by the same form.
In order for the transistor not to burn, it is necessary to limit the current supplied from the hall sensor to the gate of the transistor, using resistance R2. With the help of the pull-up resistor R1, the transistor is locked in the absence of a control pulse.
Ignition coil activation is indicated on the diagram.
List of parts.
Tr1 - ignition coil from the ignition contact system.
VT1 - IRF640N
R1 - 10 kOm
R2 - 100 Om
Cooler cooling system with built-in sensor of the hall.
Penny details. To me all has managed 2,5долл. The coil and cooler were naturally already in use. Also, for installation, a heat conductive paste is needed for the transistor and the cooling radiator. As a radiator, I decided to use what was available. A piece of aluminum is perfect. Connecting wires.
A transistor can be used either for a voltage of at least 50V and a current of 5-10 amperes.

Resistance I used a power of 0.5W.

I will explain the installation of the circuit the next time I start the assembly. Today, only preparation and verification of everything necessary. Yes, I need a mounting board, I cut a piece of plywood 180x170x10mm.
Soldering will naturally require a soldering iron, but in principle everything can be done on twist, for one-time use.
