Hey guyz this time i m making a variable bench power supply this is the most useful equipment for a hobbyist and diy maker cause while making or testing circuits it needs different values of voltage and current.
A lot of people use things like modified pc power supplies but i wasn t in favor of this because i wanted something smaller lower current and cleaner from an rf perspective.
An ideal workbench power supply should have both 5 volt and 12 volt outputs with 3 3 volts being a nice option as well.
Access to a high current bench power supply to temporarily act as an input can also be useful.
There is no power out for 12v fan.
In most cases you won t need to troubleshoot at all and everything will work perfectly.
In this episode i will show you in great detail how to create your own bench power supply from a pc power supply.
That s why every diy maker must hav.
Diy variable power supply with adjustable voltage and current.
For the next step i am considering to add current control circuit.
And you can then give yourself a pat on the back for creating a useful piece of prototyping and testing equipment by yourself.
Variable voltage power to the people a good power supply is useful when working with electronics but it can be pricey.
It should be capable of providing several amperes of current for each voltage.
If you want to customize the size or output of your benchtop power supply building your own can be a good option here are the.
A big bad high voltage bench power supply note that the photos are hyperlinked to full size photos in grisly detail i got tired of running into the limitations of my heathkit ip 17 high voltage bench power supply.
