MY PORTFOLIO

Procedures;

1.Cut a piece of stripboard to 13 tracks x 35 columns (assuming the use of the 50mm heatsink given).

2.Drill four 1.5mm holes for the thick legs of the terminal blocks, two 2mm holes for the thick legs of the fuse holder, and two 3mm holes for the heatsink and 7805 bolts.

3.Fit the four wire links.

4.Fit the four 1N4001 diodes, taking care that the polarity of each one is correct.

5.Fit the two 0.01μF and the single 470μF capacitors. Ensure that the polarity of the 470μF capacitor is correct. The leads will be marked with '+' or '-'.

6.Fit the two terminal blocks.

7.Fit the fuse holder and insert the fuse. Clip the cover over the fuse holder.
8.Bolt the heatsink to the board.

9.Bend the leads of the 7805 and position it. Bolt it into place before soldering the leads to the board.

10.Cut the copper tracks where an X is shown. Cut any tracks under the heatsink that might short out the 7805 or other stripboard tracks.

11.Connect up a 7V - 35V AC power supply and test the circuit by placing a volt meter across the DC Output terminals. The voltage should read approximately 5V DC.




“ I chose this project because we worked on it as a team and besides, we spent more time, effort but at least we gained more knowledge upon assembling the parts of the power supply. Since I'm taking up TLE, I know I can use it it to my field of specialization.”
