inertial propulsion with gyroscope

[sm0ky2]

IC's allow for a more simplistic stepper motor control


Especially if you only need a few steps


You can time it with a sensor input, photosensor, reed switch, etc.
mechanical switch or what have you, to allow for multiple events
with a degree of synchronization.


The IC can be used to create a timed event in a cycle
or in response to an input to one of its pins.
Or both if you wanted to.


You can tell it to deliver a pulse of x for time T1
and a pulse of -2x for time T2
where x is whatever voltage and current you are using.


All this is done with the prefabricated gates and switches
built into the integrated circuit. This takes the software out of it.
You just connect the pins the way you need them
and supply the appropriate input powers.

If you want to use software control there is no need to
write your own software.


Hard drive control modules can be used.
The code is already there for us.
Sort of fill in the blank location that handles
both 360-degrees of rotation in tiny tiny increments
with extreme accuracy
but also the radial distance from the axis
It's already set up for complete arc-radial control.


There's a built-in speed function
and most of the rest of the code can be cut out


we can remove the additional hardware and attach our
devices directly to the motor.
Has a pretty large footprint and more inertial mass
and probably more power requirements than just an IC
But any way you go with that will require an advanced chip
memory storage and higher power requirements.
And possibly knowledge of software engineering.
Seems like the extra package of an old hard drive
could be worth carrying, for the time may save.

@Laurent: your part 12 video is great (clever test) and it taught me something new (at least new for me). It is also instructive that the gyroscope must have a minimum high turning speed in order to exhibit its strangeness in a real world contraption. I learn very much from your videos and it makes my replication more directed in the right research direction. You are the forerunner into the wilderness paving a way for me and others to follow.

I uploaded a video to my YouTube channel https://www.youtube.com/watch?v=8ObaUz8sqkY (it is just idle talk, a presentation of the components that go into my replication, nothing moves yet)

I just learned that it is not a good idea to upload a 4K video to YouTube, it takes ages. But YouTube will present the 4K quality version if you have a high speed internet connection. (I use the Panasonic HC-VX989 Camcorder which I like a lot. For its price of about EUR 560.-- it offers a lot. But some smartphones can now do similar quality videos.)

Hi conrad

very well done video, and i can't wait to see the progress. I will learn also a lot for sure.

Thank's also for your propositions for the stepper motor. I have found in my drawer an old freeduino v1.16 and a arduino MEGA 2560. i will probably have to order the motor shield.

Will have a visit to the arduino retailor.

And out of topic you made my day when i have seen your video on the boyancy wheel. Very clever and so simple.

There are some Arduino Motor Shields and a lot of different Arduinos out there in the world and in drawers of enthusiasts. One has to investigate which works with which. I once bought the Arduino Due, but was annoyed by several compatibility problems specially with libraries. Now I use the Arduino Uno REV3 (only EUR 21.--). The Uno was always the most widely used Arduino and therefore most things (shields, libraries) worked with it.

You can now program the Arduino with the web browser https://create.arduino.cc/ . The library for the Adafruit Motor Shield V2.3 is #include <Adafruit_MotorShield.h> . Once I am confident that my Arduino Program works, I will of course share it with whoever wants it. If you harm yourself or if you become rich or if the men in black come to you is then your problem.

The Adfafruit Motor Shield V2.3 should work with the following Arduinos: cited from https://learn.adafruit.com/adafruit-motor-shield-v2-for-arduino/faq

==============================================================
What Arduinos is this shield compatible with?

It is tested to work with Duemilanove, Diecimila, Uno (all revisions), Leonardo and Mega/ADK R3 and higher.

It can work with Mega R2 and lower if you solder a jumper wire from the shield's SDA pin to Digital 20 and the SCL pin to Digital 21

For use with the Due or other 3.3v processors, you must configure the board for 3.3v logic levels. Find the set of 3 pads labeled "Logic". Cut the small trace between the center pad and 5v and add a jumper from 3.3v to the center.
==============================================================
#include <Adafruit_MotorShield.h>
Adafruit Motor Shield V2 Library library (written for ANY architecture) supports:

101, Adafruit Circuit Playground, Adafruit Circuit Playground Express, Due, Duemilanove, Esplora, Ethernet, Industrial 101, Intel x86 Boards, Intel x86_64 Boards / IoT Gateways, Leonardo, Leonardo ETH, LilyPad Arduino, LilyPad USB, Linino One, littleBits w6 Module (Leonardo), M0, M0 Pro, Mega ADK, Mega or Mega 2560, Micro, Mini, MKR FOX 1200, MKR GSM 1400, MKR WAN 1300, MKR1000, MKRZERO, Nano, Primo, Primo Core, Pro or Pro Mini, Robot, Star OTTO, Tian, Uno, Uno WiFi, UP² Board, Windows 10 IoT Core, Yún, Yún Mini, Zero

For powering the Arduino on a spacecraft I use the following AA battery or AA rechargeable battery box:
https://www.amazon.de/dp/B078HDGBJC/ref=pe_3044161_189395811_TE_dp_1
It might be a problem to power the stepper motors from the same batteries (if power for the motor shield comes via the Arduino) because the stepper motors might draw too much and the Arduino resets because of a brownout (Voltage drops too much). So, the stepper motors (the motor shield) might need their own batteries. A lot of batteries on a spacecraft, that is why it has to stay on earth for now.
I have not yet looked into the rechargeable LiPo accu packs, which might be much smaller (but more expensive and one needs a different charger).
