Mailman 3 Makecode Arcade, pybricks/pybricksdev, LEGO PF/PU, open source Robots with docs, wokwi - Edu-sig

11 Dec 2023


      A few cool tools for Python (and STEM) in application, OTOH:

## Makecode
Makecode Arcade has Blocks <-> Python <-> JS
- New Project > Blocks > +Extensions > Robotics > ~List all
[Makecode-compatible devices]

### vscode.dev
- https://vscode.dev/
- Install "python" extension
- Install "pyodide" extension
- Install "jupyter" extension
- Open from GitHub
- Run the Python in the Jupyter notebook locally
- Save to GitHub


## Pybricks
- Web: https://pybricks.com/
- Src: https://github.com/pybricks
- Code and Flash LEGO smart hubs with Python
  - Flashes Python to the device WebBluetooth

## Pybricksdev
- Docs: https://docs.pybricks.com/en/latest/
- Src: https://github.com/pybricks/pybricksdev
- Flash LEGO smart hubs with Python
  - USB,

## Modality Integrated Learning
- Lights (Bits as Voltage to Photons)
- Sensors (Physical phenomena to Bits)
- Servos (Rotations in radians or degrees,)
- Motors (RPMs)
  - Things that spin; things that have mechanical angular momentum
    - All power tools, basically

        > I Put 44 Mechanisms In 1 LEGO® Machine! You'll see the
testing of more than 40 Mechanical Principles/Mechanisms using LEGO®
Technic parts


### LEGOs with voltage; PF, EV3/NXT, PU

IIUC:

- There are at least 3 connector specs in the LEGO(R) ecosystem:
  - PF: Power Functions (2009+)
    - LPF2: LEGO Power Functions 2
      - Technic
      - WeDo 2.0, SPIKE Prime
  - NXT/EV3 (2006/2013)
  - PU: Powered Up (2016+)
    - Boost
      - Move Hub with 2x Ports, 2x embedded motors, and BLE
    - City Trains
      - Hub with 2x Ports, and BLE

- (e.g.) LEGO Boost Creative Toolbox has 1x LEGO Move Hub (which works
with their apps, pybricks, and pylgbst,), has 2 ports, and 2
integrated motors
  - https://www.google.com/search?q=building+instructions+for+lego+17101
    - Sometimes, PDF Building Instructions are easier to work with
than an app on a tablet that keeps going to sleep.
      - https://trevorsandy.github.io/lpub3d/
        - This looks like a good way to document 3d building instructions.

- Is there a way to connect LEGO PU motors and sensors to a Pi with a
2x20 Pin (~IDE) HAT
  - https://www.raspberrypi.com/products/build-hat/
    > The Build HAT also supports motors and sensors from the LEGO®
MINDSTORMS® Robot Inventor kit, as well as most other LEGO devices
that use an LPF2 connector.
    - Does that mean it works with PU,
      or is there no product to connect LEGO PU motors from our one
kit to our one Pi ?

      - https://uk.pi-supply.com/collections/all-raspberry-pi-hats-and-phats/product...
        - USB to 2x20 Pin GPIO

### Wokwi Simulator
- https://wokwi.com/
- https://wokwi.com/projects/new/micropython-pi-pico
- What is PWM? How to fade an LED on and off, control a servo, control
a case fan with variable speed
- In the Wokwi simulator, when you pause || the circuit that runs your
{Python,} code, and then hover over a pin, it shows the pin state;
high, low,
- Makecode Arcade and TinkerCode are also a simulators that don't
require actual devices


## Actual work tho,

- https://github.com/marketplace/actions/setup-micromamba
  - [ ] Write a Dockerfile that installs your stuff
  - [ ] Make sure that your repo with an /environment.yml works with:
    ```sh
    pip install pipx; pipx install jupyter-repo2docker  # or just: pip
install jupyter-repo2docker
    jupyter-repo2docker --no-build --debug .
    jupyter-repo2docker --no-build --debug
https://github.com/binder-examples/conda
    ```
