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 ...

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 ...

Trying to get 5 V using MT3608 (step-up boost) but without success
I designed a circuit to generate 5 V using a 3.7 V battery and an MT3608. The main problem is that I can't get 5 V but just 3.5-3.9 V, even after changing resistors.
I tried everything:
Changing R1 ...

Input of 20~23v, need output of 24v [closed]
I have a supply that outputs either 20v or 23v, I need to step that up so it is always a fixed 24v no matter what. How can I make sure it is always a fixed 24v?
Edit: This is for a coin hopper. It ...

How does the step up booster in the attached schematic work?
There is a 3 pin SOT-89 package IC DC step up that converts 1.5 V to 3.3 V as shown in the picture.
My questions are:
Does anybody have a link to the datasheet of the 433p?
How does this circuit work?...

Converting a fast-switching 0-2.5V input to TTL signal
Dear fellow engineers,
I am attemping to convert a fast switching (~ns) 0V - 2.5V pulse from FPGA into a TTL-standard (0V - 5V) signal. I have been browsing for voltage regulators online. Most of them ...

Step Up Circuit does not work
I am using an IC as a step-Up converter in my PCB.
It is supposedly to increase voltage from 12V to 30V.
This is the chip that i used.
