    Hi all

    I was wondering if i could recieve some advice/ knowledge. I was wondering if it is possible to step down 110v to 6v dc on a miniature scale and how to do it. i would be grateful for any know how on this issue.. it is a personal project in which i hope to use a miniature 6 v actuator tomove a small plastic cover over a connector block on a unit i work with daily.

    Thanks for the help

    Much appreciated

    Also would it be ossible to power the actuator by stepping down the power with resistors

    I have a casing of 7cm long by 5cm wide and 4 cm high. the actuator takes up very little space its 2cm by 2cm n 1 cm high... the actuator needs 250mA with a 5v DC supply

    most mobile phones chargers are 5v and they can deliver currents in range of 300mA to 1 amps.. and they also very small .. if u open the case of charger ( it some ti,mes opens but other times u woukd have to break it ) thwre is a small pcb .. realy small u can hide it in mpst places.. i have been using this way in many places..

    regarding ur question whetjher a single resistor coul be used to step down voltages .. NO .. because it will still be u need dc..

    Just a note - USB supplies 5v - If you have a computer that is always on ( as I do ) - You use a USB cable to your circuit. Uncertain if you need the exact 6v.

    Yep. USB= 5v @ 500ma.

    Even if you don't have a port handy. You can get wall plug USB power supply for real cheap on ebay. Or if you need it asap. Pay a bit more at your local electronics store.
