making my 9v dremel into AC powerd
 

hey guys i have one of the cheaper chicago brand dremels and the thing is great! it has a bunch of pieces that make any job possible.

one problem.

at 9.6volts the thing is pretty weak.... there is no way i could dremel a motor shaft or really anything that is tough...

i was just wondering how difficult it would be to hook it up to the AC power of my house.

i still do not understand why things cannot just be plugged into the wall and call it good but i would like to figure it out.

here are some questions i have..........

-my hyperion 1210i needs a power supply to make it work. i realize it runs off 12v so what does the power supply do with the 120V my AC power puts out?

-if there was a capable esc of holding 120 volts could you run your rc car directly to the AC with an extension cord? i realize this is pointless but i am just wondering. or would it pushing too many amps?

-the old style 15min chargers do not need a power supply... what do they have inside them that alows the use of AC power?

-if i got one of those ac adaptors that allows you to select the output 3.3v 5v 12v would that work for the hyperion instead of needing a massive power supply? since it would only be pushing out 12v?

-last! how do i get my dremel to run off AC power? so it will have more power!

thanks for any help guys.


also... i am searching google for all these answers but have not come up with anything yet... hopefully i can learn a little basic electrics through this thread.

You would need a power supply, motors (that are used in dremels) will not run off of AC current, i wouldnt know how many amps it would draw though.

You could get a a larger battery pack and hook it upto your dremel, say a ~12v item that uses decent cells (A123 or generic versions there of), but making it AC powered is impossible essentially. As for your your charger in need of a power supply, look up AC/DC power supplies to understand how they work; basically take 110v of AC (alternatiing current) and turn it into some useful DC (direct current) voltage, usually 12v or so, which is what your charger needs to function.

thanks neil! will look more into that stuff

i didnt know that motors wouldnt run off ac.

interesting!

AC motors run off of AC currents, DC motors run off of DC current (you can get AC/DC converters, DC/DC step-down voltage converters, and DC/AC converters- those are limited by the current output of the DC source though; sort of thing you can plug into a car cigarette lighter socket to power a laptop or gaming console).

mmmmmmmm i understand! makes sence.
