First of all, I would like to thank Mr. Xin for joining the team. I have written to Allan Young about you, and I had every intention to use my connections of a Y Combinator company I have invested to present you in front the best incubator in the Valley. I was very grateful that you agreed to join us as a co-founder. You attention to details in your design philosophy impressed me. You are easily the best and most talented mechanical and industrial designer I have come to know in my life.

2nd of all, I would like to thank my team. I can be too logical and too demanding sometimes. And I understand humans are, after all, humans. And we are not machines. I hate debating and I thought my study of Buddhism helped to control my temper. But it still got to me from time to time. And I would like to say thanks for your tolerance. I hope that we will build a great company, that don’t care much about money but a company that will allow us to leave something we are deeply proud of and affect this generation and the generation coming after us.

3rd of all, I would like to thank my family and close friends. You are my support in my darkest times. I believe that I am still in a difficult time. And I rely on your understanding and support. Thank you for believing in me. I need that.

I lost my track of thought when the cab pulled over, but I think that should be about all that I want to say for today. Happy Thanksgiving.

A lot of modifications are required per this test’s conclusion. The current version uses a commercially available ESC with sensorless drive. This results in terrible uphill start and completely unpredicatable braking behavior. We will first try a commercial ESC with Hall Effect sensor control. If still not working as desired, we have started looking into custom ESC for closed loop acceleration and deacceleration control.

The main controller was a Punchthrough Bean Arduino BLE board. We made an simple iOS app to control the throttle.

We also got to borrow 3 x 3D printers from a hackerspace nearby. They printed overnight for our wheel and fixture.

Before presentation

And it worked!

and first place! (we ‘acqui-hired’ another team during hackathon :D)

• Much more elegant
• Added search bar which is not available in first version
• It is rewritten in Ajax
• Much faster response
• Completely client side
• Single page app hosted on Github Page

I again posted on Hacker News and Reddit. This time, I received almost no traffic from Hacker News but significantly more traffic from Reddit. As comparison, I received huge traffic from Hacker News but almost no Reddit traffic from my 1st MVP.

There were several things I think I did wrong in running this test

• The new version didn’t have capability to track user behavior at search bar (which could be significant)
• I didn’t post on HN on the same day of the week and at the same time, which makes the HN result inconclusive

Possible Assumptions

• Does Hacker News only recognize new material?

Conclusions

• Reddit seems like the better UI design than my last version
• Reddit and HN are probably different type of users.

The Most Important Lesson: The Fame is Only Temporary

And I will keep reminding myself of this fact.

HN Can Really Drive Traffic

Thanks Guys~

HN Has a Lot More Global Readers Than I Expected

Few People Discovered API

Top Tech Cities in U.S.

And Around the World

This is my first popular Github project, I got on Github trend probably due to the HN traffic. I have since updated the UI and release 1.0 stable version. I hope you guys like it :)
