1.3V – 15.5V @ 2 Amps Power Supply
If you find my design interesting, you could make a small donation:
This is a small size power supply with low cost and easy to make that only taking about 5 more hours. I was very happy with it and would share with you.
Power Supply Specifications
Input: 5v-16v/3A DC
Output: 1.3V – 15.5V/2 Amps
Step 1: Materials and Tools
Here is a list of materials and tools I used for this project.
2 x LM2596S DC-DC module link
2 x Voltage/Current DC0-100V LED meter link
2 x WXD3-13-2W-10K link
2 x D3-13-2W knob link
2 x 4MM banana jacks(Red + Black) link
2 x 4MM banana sockets(Red + Black) link
1 x switch 117S 8.5*13.5MM link
1 x Power Jack DC-022 DC 5.5mm 2.1mm link
1 x AMS1117-5V link
1 x 5V 30mm fan link
6 x 2.5mm/6mm screw
1 x DC adapter 16v / 3A, the voltage range between in 9v~16v would be better.

Step 2: Make the Enclosure by 3D Printer
Download the STL file from here http://www.thingiverse.com/thing:1420193
And take about 2 hours to print them.
I have removed the USB slot which the 2 holes on the front panel, the new one will not be any hole on it.
Step 3: Modify the DC-DC Converter
take away the small one of potentiometer which is on the DC-DC module, and replace the big one of potentiometer which shown in the picture. The picture 1 is not correct, please follow the number 3-3, 2-2, 1-1 to connect together as picture 2.
Step 4: Schematic and Diagrams
Refer to the diagram to connect all of parts together
