I have been wanting to build a Adjustable Constant Current Load project and I have a couple questions ... The schematic is listed below and do you guys see any problems or anything can be upgraded or should ??? My idea was to change the mechanical switch to a soft latching power switch ... Then I will be using dual display instead of using the single display and a switch... I was thinking about using battery power powered but I have not done the math to see how long the battery will last or was it even worth or just build a power supply board ??? Whats your thoughts ???
