Does the oscillation frequency of my step-up (boost converter DC-DC) depend on the characteristics of my motor?
I have to step up a 4V supply (the generator is a button battery) to a 12V voltage to supply my motor.
How do I size the components of my step-up converter? To compute for example the inductance and ...

Zener instead of resistor divider on dc-dc converter feedback pin
This dc-dc converter steps up voltage from 3.1V to 7.5V. I'm curious about the unusual D2 zener + R3 resistor to set the output voltage, instead of the traditional resistor based voltage divider. I ...

How to conveniently generate variable programming voltages (12V, 12.75V, 14V etc.) in an Arduino context?
I'm playing with EPROM/EEPROM's and I need various voltages. For one, EEPROM I need to be able to generate 5V, 12V and 14V at around 30 mA. Question is how I do that the easiest. I'm thinking I could ...

Can very high voltage and very low current AC produce strong magnetic flux in the coil?
I have done some research and also conducted some experiments and found that the magnetic flux in a transformer or a coil mainly depends on the number of turns and current flowing in it and not the ...

Creating higher voltage from DC motor
I have a DC motor (5 V, 600 rpm). I use it as a generator. It produces near 1.5 V max.
This voltage may differ while using it in the application and I can't control it. I want to raise this voltage to ...

What is the "best" way to make a diy 7v rechargeable battery?
I have a device (the wii "sensor" bar, basically an IR LED array) that the literature says takes 7v. I can't find any battery offerings that come in 7v, but many that are 3.7v, so I am stuck ...

Step-up like logical "inverse diode" operation [closed]
In the same way that a diode lowers the voltage typically by 0.6V/0.7V, I would like to understand the minimum and simplest circuit to obtain the reverse, i.e. raise the voltage by 0.6V/0.7V compared ...
