Maker Faire

May 17th, 2007 — 9:26am

Here are some photos of project I was working with Jay Bain for Maker Faire this weekend May 19th and 20th. It’s a double tandem bike pair (for 4 people total). They are going to do final assembly and welding on the event. I won’t be there because I am traveling to Philippines.

Tesla Motors

May 4th, 2007 — 9:07am

I went to see presentation of Tesla Motors. It’s an electric powered sport car. It can do 0 to 60mph in 4 seconds and has radius around 200 miles. Most important is their battery pack which is composed of several thousand standard Li-Ion battery cells and weights around 950 lbs. It takes 3-4 hours to fully charge using 70 amp current (that means, with ordinary home plug, at ~12 amps, it would take you around 24hrs to fully charge the car). Another interesting thing is that, since electric motor (that weights only 70 pounds) can produce enough force at low rpm, it doesn’t really need gear. Tesla roadster has only two speeds and is completely electronically controlled.
