5V Power supply unit (PSU) Part 3


Further to the previous post on this.  I have now made a new version of the 5v power supply unit.  This works nicely, other than for the lower voltage out.  But that could be due to using cheaper 7504 modules.

Due to using strip board the overall build cost is significantly reduced,.  Bluetack currently holds the leads for the Voltmeter in place.  The leds need cutting to size and soldering in place.   However this is is my last volt meter module until I order some more.
