Ahh! I am back ! I have been travelling a lot and quenching the inner travel monster in me. According to my calculations largely based on GPS i have done 6444kms in the span of 8 days this month. That an average of 800kms per day. I covered states from Tamil Nadu in the south to Jammu and Kashmir in the north. The travel bug is now on a hangover of sorts ! Quite a while back, i made an adjustable, tiny-form-factor,no space wasting supply as you can see here . I really loved that project and went on to make it a bit better. Since, i wanted to keep that form factor intact. I went on and invested in getting the PCB made professionally. It turned out great! I added the two things to enhance usability :

  1. Ability to measure current on the fly without messing( Ah! Argentina..:/ ) with  whats connected to the supply.
  2. Provided some pads on which you can use a multimeter to set voltage without poking into the breadboard.

Here is the final board and the kit-assembly sequence.
