Prototype 2 home built quad copter Success

 

Cool! This test of my second prototype worked. This first prototype didn’t. Not bad for an hour of work and less than five bucks of parts.

Next step accelerometer and or gyroscope. I think I’ll try it with Parallax propeller, netdruino and arduino.

IMG_0872I mounted the motors on the top of stronger spars with a glue gun. Dressed the wires too.

(FYI It’s a mountain Dew)

Although highly unstable I’ve proved to myself that these motors have enough lift to experiment with. If you look closely in the video you will note that two motors on one spar or the spare itself is tilted slightly. Hopefully this can be overcome once I add some sensing and logic to the motor control. This is just motors straight to power supply. Might try warping the spar with some steam. I’ll probably wait until after I add the control electronics.

Great second prototype test proving the motors have enough left to experiment with.

  1. Cool tiny quad rotor. Has hint for contra rotating motor prop sets. http://bit.ly/lbd0DP

    Amazon has: http://amzn.com/B004LYDC6U the Silverlit X-Twin plane for $25 x 2 for four motors and props is $50. Still cheaper than 300 – 1000 for ‘store bot’ diy

    I have a couple 2 and 3 axis accelerometers around the shop.

  2. It occurs to me that I can turn one spar upside down and reverse polarity on the motors to potentially overcome the torque problem.

  3. It occurs to me that turning something upside down and reversing the polarity is not gona give me a contra rotating propeller. Considering a prop warp with heat gun now.
