Final Year Project 2 Week 7 & 8
Week 7 & 8
This week, make inverter circuit and charging circuit. The Inverter is use to convert Dc to Ac, since the output that produce in dc, so it need to convert. The charging circuit is use to charge the battery in dc, The battery use as supply. Figure show the schematic diagram both circuit.

Final Year Project 5 & 6
Week 5 & 6
In this week, the component mechanical start finding which is spur gear (Pinion) and rack. The select this component take two week, because it need some research about this component.The both part is function to rotate shaft dynamo. The spur gear (Pinion) will be install at dynamo and rack will be attach at ramp. The selection spur gear and will effect of dynamo.This project the spur gear and rack has been selected.
Spur gear (Pinion)

Final Year Project 2 Week 3 & 4
Week 3 & 4
In this week will be explain the dc booster circuit. Why this circuit need to use?. After test this dynamo it can produce only 0V-4V, so it need to up the voltage to produce 12V. This was design and tested. Figure show the circuit design and tested.
