1.25 TO 25VDC POWER SUPPLY

Hi,just an easy instructable to show you how to make a 1.25v dc to 25v dc power supply.

Step 1: Epuipment

We will be doing a lot of soldering for this project,so get a full roll of solder at least!So, with all that,we need

***************************
Soldering iron
Desoldering iron
Solder
Lead trimmers
Wire stripper
Helping hands[unfortunately i didn't had them,but still a recommendation]
***************************

Step 2: Parts

As you can see from the schematic, there are plenty of parts to this circuit.
So, lets get started with the parts
*******************
Load switch[120vac,6a]
3a fuse
28vac transformer
2a bridge
1000µf electrolytic capacitor
10µf electrolytic capacitor x2
LM317T IC
TO 220 Heatsink
0-5k potentiometer
240 ohm 1/4W resistor
Prototyping board

Step 3: Final Step

Solder all the parts and you are done.
If you power supply works without LM317T smoking,then you re successful. If not,there is something wrong.
