Why does adding a capacitor in series to an AC motor increase its speed? The capacitor does boost the voltage somehow because the input voltage is 132v (mexican mains) and coming out from the capacitor are 230v. This has to do with the inductance because it wont work without the motor. I made...
I got a damaged ATX PSU with primary transistors (13007) blown. When opened to repair I found that it doesn’t have EMI filter (markings present on pcb). I decided to include one and designed as attached pic.
As not an expert I’m not sure about the required values of X caps and inductors. The...
Hello,
For my project I need to build a variable frequency emitter, with a frequency between 100MHz and 3500Mhz.
I saw some simple RF circuits on the Internet but I don't think they can reach such high frequencies.
Here is a circuit I've found :
I don't need to transfer any information, so...
I have bought a capacitance and inductance meter from a 2nd hand shop and there is not manual. So I don't know how to use it. I don't want to damage the device, so I have searched in the net and I have found some information about the mode 6243. My model is 6243+, so I attach some pictures and I...
Hello,
I have seen numerous Youtube videos on super high voltage Joule Thief projects. They are using small one inch ferrite toroids and from single 1.5 volt AA battery power a 3-5 watt 110-220 volt cree LED brightly consuming merely 200 mA of current from the battery! The following link will...
