Week 14 Fyp 2 : Prepare for presentation

Week 14 Fyp 2 : Testing functionly and take the result

After making the connection on my project, it's time to see how this works. Video below shows how it's work.

From that i get the result for input/output voltage, current load, and solar output.

So, Vin(from battery) = 12.22V
      IL(Load current)   = 0.86A

Solar Output (Time versus Voltage)

Time (H)	Voltage (V)
0800	10.21
0900	10.43
1000	12.35
1100	17.63
1200	18.54
1300	18.52
1400	17.41
1500	15.52
1600	10.41
1700	8.32
1800	7.21

Current load

Calculation for charging the battery.

Battery rated 7AH

Current load, IL = 0.86A,      7/0.86 = 8.14Hours / 8H 14min (for load).

Charging time, 

Solar 12V, 10W

Solar Current, Is = 10/12 = 0.83A

So, 7Ah(battery) / 0.83 = 8.43Hours / 8H 43min to charge the battery.

  

Week 13 Fyp 2 : Making a pole of my project

This pole height of 10 feet and can be adjusted. Placed above the solar poles can also be adjusted and is under the control circuit. Pictures below shows a picture of my project.

Week 12 Fyp 2 : Soldering the component on my PCB

Soldering the component on my PCB.

Lamp circuit

Charging circuit

Week 11 Fyp 2 : Start making the PCB for the circuit

I used OHP paper as method on my PCB circuit. After printed the circuit on OHP paper we iron it on PCB for 30 minutes. It's take long time to do for one circuit and the result from this method is very satisfied. Pictures below shows how it's made.

This is the result.

After that we etching the PCB to remove the copper that no need on PCB with Acid call Ferric Chloride Liquid. It may take 30 minutes to remove the copper.

This is the result....

Week 10 Fyp 2 : Modification of my LED Lamp.

This LED lamp rated 4W for each LED light. For one lamp have 4 super bright LED and i use 5 lamp on my project. Below is a picture of my LED lamp after modification.
