One DC-DC circuit board per project box
Original item on the left - finished item on the right
I found that the 1000ma converter is insufficient for my Canon PowerShot A40 digitcal camera
when the flash operates. A 1500ma converter is sufficient in this use.
Circuit board from the purchased "cigarette ligher" package placed into the project box.
At position T6 the voltage selector knob has been removed and a jumper soldered into place for the
desired / set voltage.
Closed box. Air holes for cooling air.
Power LED just visible.
Project box, mounted via Radio Shack SuperLoc / 3M unisex fastener.
Air holes positioned so that rain does not directly get into the box.
Boxes may be easily removed when not needed.
