Intro: Tri-Regulated 1A Power Supply
I'll help you if you want to make a power source that can deliver 5 volts, 9 volts and 12 volts.
This basic but probed and functional instructable will help you to print make de PCB, edge solder and probe your Power supply.
It can deliver 1A max for basic electronic circuits in the future i'll make more Amperes power supply.
BUY A FUSIBLE THATS PUT IN LINE WITH THE CABLE
THERES A TERMINAL BLOCK ESPECIALLY FOR IT, IF DON'T WANT TO PUT A FUSE ONLY BRIDGE THE TERMINAL BLOCK OF FUSE (NOT RECOMMENDED).
ALL RESISTORS 1/2 WATT
THE TRANSFORMER WAT YOU SHOULD USE IS 15V @ 1.5 A OR MORE, WITHOUT CENTRAL TAP IF YOU HAVE ONE WITH CENTRAL DERIVATION USE ONLY THE SIDE SECONDARY CABLES! :)
You can add a discipator for everyone Regulator there's space for a little aluminium discipator. YAY!
Step 1: SCHEMATIC
The basic schematic for you can see the array of electronic components.
If you want to modify the proyect send me and email and with very very pleasure i'll send you the .brd file for pcb and the .sch file for the schematic
my email is: email@example.com
Step 2: PDF Files C:
There is the files thta you want in .PDF file all ready to print! :)
One is for the art work and the other is for to print the pcb components mask Yay!
Remember use a toner transfer for circuits
DON'T PRINT IN NORMAL PRINTER PAPER
IT HAVE TO BE IN SPECIAL CIRCUIT PAPER LIKE COUCHÉ, PERIODIC OR PLATISTIC SHEET FOR
Step 3: FINAL PCB Circuit
I made my own and obviusly works fine
Only for representative :)
If you want to put your in a little box it wouldbe better
*REMEMBER TO PROTECT THE DOWNSIDE SOLDER AND NETS FOR SHORT CIRCUIT
THE CIRCUIT CONTAINS DIODES FOR PROTECTION BUT IS BETTER NO TO PROBE MORE
Enjoy this basic and functional instructable.
