inertial propulsion with gyroscope

[conradelektro]

Laurent, nice build. And I am glad that you are also using an Arduino. The way forward with these strange gyroscope machines is precise control by microprocessor. It should be possible to find what is really going on.

It would also be good to controll the speed of the gyroscope. The speed of the gyroscopes should somehow correspond with the speed of the arm.

I am collecting materials for a super machine with strong stepper motors, good stepper motor drivders  and the beautiful gyroscopes from England, which come with their own DC motors. At least I can let these gyrosopes turn with different speeds by varying the supply Voltage (2, 3 or 4 AA batteries).

Great plans but slow work, greetings Conrad

Good stepper motors https://www.amazon.de/Schrittmotor-40mm-4-Leiter-3D-Drucker-Verdrahtung/dp/B01KJOM7KC/ref=sr_1_18?s=industrial&ie=UTF8&qid=1520699654&sr=1-18&keywords=nema17+schrittmotor


Good driver (one for each stepper motor) https://www.amazon.de/TopDirect-Stepper-Schrittmotor-Treiber-Controller/dp/B0711J1K66/ref=sr_1_1?ie=UTF8&qid=1520699539&sr=8-1&keywords=Stepper+motor+controller+9V

Hi conrad

thank's for info, will read  for my new build.

I have just finished the new proto and have some very positive results.

It seems that the rower system is promising, and sure the arduino will be used for the improvement.

Will go on the test those next days

Greetings
Laurent

How to speed up two servos (each 1 degree step happens faster than the previous):

#include <Servo.h>
Servo servo_0;
Servo servo_1;

void setup()
{
  servo_0.attach(0);  // attaches the servo on pin 0 to the servo object, different pin can be used
  servo_1.attach(1);  // attaches the servo on pin 1 to the servo object, different pin can be used

  servo_0.write(0);          // send servo_0 to position 0 degrees
  servo_1.write(0);          // send servo_1 to Position 0 degrees
  delay(2000);                  // wait 2 seconds (2000 ms)
}

void loop()
{       

for(int i=0;i<=170;i++){     // servos step from 0 to 170 degrees
  servo_0.write(i);
  servo_1.write(i);
  delay(25 + 170 - i);           // 25 ms minimum delay, could be less, has to be tested,
                                            // delay is decreased from 25 + 170 ms to 25 ms
  }

for(int i=170;i>=0;i--){     // servos step from 170 to 0 degrees
  servo_0.write(i);
  servo_1.write(i);
  delay(25 + i);                  // 25 ms minimum delay, could be less, has to be tested,
                                          // delay is decreased from 25 + 170 ms to 25 ms
  }
}

One has to test the minimum delay needed for a particular servo to complete a 1 degree step  (in the above example it is assumed to be 25ms).

The problem is that a servo is inherently slow.

hi conrad

Just tried your softs and they work well thanks

But today i got lost in all the testing with rowing or not rowing and i decided  to get a reference for my future work.

So i redo my best fiala system with a better motor and a regulator for different gyro setup and this one will not be dismantled for other experiments

I have ordered a bunch of those figdget spinners with outer brass ring because they seems to be very close to what Fiala describe in the patent.

it will be MY SCALE for comparison with other experiments, because it works so well.

hope this helps

Laurent
