Havent been lucky the last weeks. Things just goes to it's maker. So my charger to an old camera as I use to digitizes magazines broke down. With that routine digitizes magazines I get some more space by throwing the paper Issue away. BUT my PS50 doesn't have a power jack. Hm.... Ok I'll print a battery a bit larger in size, not a problem as I don't have to close the lid on the camera. Big enough holding a variable regulator. Encloses scadfile so you can adjust to what power regulator you want and what kind of powerjack you like. Happy scadding and printing.Bought a bounch of these 3A variable regulators. Stable and powerful. http://www.ebay.com/itm/Power-Supply-LM2596-DC-DC-Switching-Adjustable-Voltage-Regulator-Buck-Converter-/351085800400?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item51be582bd0 Fits into the printed "battery" circuit board against the flat side of the "battery". Don’t forget to Isolate the outgoing + ( picture ) with heat shrink tubing. And put some isolation above the battery terminals before inserting the regulator. I show in the picture how I soldered another temporary wire to guide the battery terminals through the case.
