To Install 12 gauge solid copper wire between all four resisters, connect resister(side) to transistor by using 12 gauge solid copper wire. By following the Circuit http://upload.wikimedia.org/wikipedia/commons/3/34/Power-supply-tester-diagram-2_26_13.pdf

Going to connect two resister(middle), and also connect 2k potentiometer to transistor.

 File:Going to connect two resister(middle). just like i soldered all four together..jpg|The distance between two middle resister is 1.5 inch so decided to connect both resister by soldering 12 gauge solid copper wire with same measurement. File:Cutting job done by wire cutter.jpg|Cut 12 gauge hard copper wire by 2 inch File:Overview of how copper wire looks on those two resister.jpg|2 inch solid copper wire supposed to connect both resister File:Both resister connected without solder by copper wire.jpg|2 inch copper wire bent by quarter inch on both side in order to connect both resister File:After soldering job was done.jpg|Successfully soldered of solid copper wire in order to connect two resister.

Going to mount all potentiometer to power supply box and use some more 12 gauge copper wire to connect different parts.  File:Side view of soldered 12 guage solid wire to different transistor.jpg|Black wire goes to ground where white wire goes to 2k potentiometer. File:Bottom view of 12 gauge copper wire soldered to different transistors..jpg|E=(1st transistor) emmiter (white 12 guage wire) connect to 2k potemtiometer and B= base(another transistor) goes to ground in the power supply File:Drilled small hole(green mark)..jpg|Drilled small hole beside the 5k potentiometer so that potentiometer gets locked and the hole prevents it from turning around File:Drilled and tapped hole in the Power supply box.jpg|Drilled big and small whole in order to mount 2k potentiometer. File:Made up hole by drill machine to install 2k potentiometer.jpg|Overlook of 2k potentiometer's after drilled hole. File:Open potentionmeter(unknown ohm) for the knob.jpg|Since this potentiometer's ohm was unknown so decided to not to use it for the power supply. File:Overview of ring crimp wire connector.jpg|Top view of all three potentiometers with its knob. File:Ring crimp wire connector used as a knob on 2k Potentiometer.jpg|Use ring crimp wire connectors as a knob on 2k potentiometer. File:Connection between 2k potentionmeter to emmiter and base of different transistor.jpg|The long white wire connect 2k potentiometer to base of transistor, where small white wire connect 2k potentiometer(same) to another transistor's emitter.

Going to Check the capacity of the Ammeter before connecting to the power supply project. Here is the video of testing ammeter. http://www.youtube.com/watch?v=sQmRdolNwOQ
