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 :
- Ability to measure current on the fly without messing( Ah! Argentina..:/ ) with whats connected to the supply.
- 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.

A diode on the bottom! Do’nt worry it sticks out and doesnt hinder!
Pads to measure output voltage!
The Headers poke into the power rail on the breadboard!
Supports standard DC jack with polarity protection
The pink jumper can actually be removed and an ammeter can be connected to measure current!
The completed board
Aligning the regulator with the silkscreen

Just in-case anyone is interested ! I am providing a DIY kit around it that is available here. Free Shipping(India Only)Yeah! Only additional tools required are just nippers( micro-shear)/cutters and soldering iron+solder. Cheers, Rohit
