  • “YIPPEE KI YAY MO” must be silk screened into this board!

  • I alone, also have that many bikes, though most are mountain bikes.

  • We would do it for money for $5000. We spent $1500, and about 350 man hours… a lot of work!

  • We never let ourselves be afraid, never succumb to the idiocy of the world. We always have a plan if Police/FBI/CIA show up, mainly just talk to them properly and clearly and remember: they don’t know what a zigbee/arduino/breadboard/hackerspace is - dumb it down for them and don’t use words like “hacker” haha. Do what you like and be happy! Then work a ton to make your money back….

  • Of course we built in safeties, I mean we had to test ride it! We wouldn’t trust it without any. The programming was skeptically checked for logic errors by many people and several hacker spaces. If wireless button transfer fails at any point and/or either of the two arduinos fail, the motor controller goes into off mode and electronic braking commences. There is a physical disconnect to the batteries as well we can reach from outside the ride. Seat belts aren’t even necessary as the g-forces push you deep into the seat, but I wouldn’t ride without them anyhow, we check them on people like roller coaster operators do. And last but not least, there is an emergency drum brake we can pull from the sidelines if ever necessary.

  • You can watch a youtube of the video here: http://www.northstreetlabs.org/TheCentriFury.html

  • No code or schematics? I’d love to know how to hook and arduino up to an IRC chat and listen for key words! This could be extremely useful for other things!

  • great write up! Did you ever find out what caused a fried mega2560?

  • a Porter Cable tool user arrives and laughs

  • in virginia on the east coast I would suggest two:

    www.priestelectronics.com - They have all the harder to find stuff from low to high power applications, even some really old looking velleman kits. I go here whenever I can because ratshack sucks!

    http://www.debbiesrcworld.com - an epic RC store!

No public wish lists :(
