Hi I have a project that will be necessary to turn 1.5 volts into 6 volts to power a 6v electric actuator. The actuator amperage consumption is unknown but will be minimal (it has a small gear reduction motor) I was initially thinking about using a relay but it's been hard to find a 1.5v relay. Can I use a transistor instead of a relay? How would I go about doing this? Thanks.
