Meeting notes
What we did last week

1.manasa watched the video about this project. She found that they buy a generator 30 dollars and they did a small battery charge. She thought about how to make the budget less.

Question: how to reduce energy loss.

We can get highest speed of bicycle.

Make the output bigger.

Use AC-DC converter.

What we need to buy and what we need to design?

Hess: it depends on what we want to learn. We can buy battery change and design a generator.

Oliver: if we can change AC-DC converter to DC-DC converter.

If we can use Mosfet to amplifier the voltage.

Hess: we can change the voltage to the 1000v. we can use mosfet absolutely.

Jack: when battery is full of charge. How to protect the circuit.

Hess: we can use capacitor to protect the circuit.

Type of Meeting: third team meeting for senior design project

Meeting Facilitator: Shi Chenghao

Notetaker: zou meiyuan

Invitees: Manasa Pothamsetty, Zhu Chensheng, Shi Chenghao, Zou Meiyuan.

I. Updates -5mins

II. Discussion

a) Different ways to reduce the power loss -10mins

b) Which parts need to be done by ourselves, which parts need to be bought directly. -10mins

c) Questions -5mins

III. The goals to do the project. -5mins

IV. Conclusion -5mins

Total time: 40mins

Meeting Notes
1.An idea about voltage stable, DIY generator(design by ourselves)cheaper

2. Decide three parts of the project: generator, solve problems about voltage, battery

3.Oliver:We can't design the battery, so we will focus on generator. 4.Battery: cell phone battery

5.Big problem: how to keep voltage stable, be weak in coding

6.Just need to focus on the first and second part

7.An idea: Use small wheel to get higher ω.

8.Talk about some prices about generator on the Internet and brush DC

9.DC-DC

10.not need consistent current, just need to consistent voltage

P=VI 11.Design a switch to protect the circuit
