Phantom v4.3 High-speed Camera

Details on how to use the Phantom v4.3 high-speed camera.

Specifications

The Phantom v4.3 (specs) features 2100 fps at the full resolution of 800x600. Features a global shutter, auto exposure control, 2GB storage. Our camera has the standard 1" C-mount, so adapters will be needed for other lenses. Phantom is expensive, with used cameras going for $30k. Lower-priced competitors such as Chronos and Edgertronic are more competitively-priced at under ~$15k, while Photron come in the middle somewhere.

Lens considerations

Invoke Python from PowerShell

Invoke Python from PowerShell including pipeline variable input from stdin.

A slightly different approach/workaround looks like this. You can pass an array of strings, or, say an array of filenames into the Python script if you dot-source common.ps1 below and hello.py is on your PYTHONPATH or is a module. You could make the -Module parameter more flexible, and expand the example further, but that's the gist of it.

Of course there's no real parallelism here, the Python interpreter fires up and runs with every input piped to it, there's no benefit of setup/teardown e.g. begin{} and end{} clauses in PowerShell's pipeline orchestration mechanisms.

The upside is you don't need to do anything special to your Python module, since all logic is handled on the shell side. The downside is with multiple arguments you're gonna be constructing arrays of arguments on the shell side in order to pipe in. Not sure exactly how that would look, you could probably do some [splatting

`raw.py`

Modification of pycine raw.py to be able to read older files. Monkey-patching BlackLevel and WhiteLevel

Copy/paste may not work as expected in the VSCode integrated terminal when running flit publish and pasting a password/token. You should create a one-time token on PyPi, with entire account scope, then in an external terminal window, run flit publish. There you can paste your token, you may have to do "Ctrl+Shift+V", or "Win+V" and click the token in your clipboard. If this step fails, you have to go to "Credential Manager" and delete the http://upload.pypi.org/legacy credential and try again. When done, be sure to delete the local credential, AND remove the credential from PyPi. You don't need to keep an account-scope credential around forever, just make one when needed and revoke it right after.

Leads

From Reddit comment by u/mpt977262 regarding the "bogus" course InspiritAI, and better resources for learning artificial intelligence and machine learning (AI/ML) below:

Amazing, free, high-quality ML education is easy to find online; there's in fact too much out there and it's hard to know which ones to stick by. The ones that I have used and can personally attest to are the following:

Andrew Ng's Coursera courses (https://www.coursera.org/collections/machine-learning): these are the classic ML courses that many people swear by. I skipped my college ML courses and just watched these myself). I'd recommend starting with "Machine Learning for Everyone" (https://www.coursera.org/specializations/machine-learning-introduction). The other courses are built on top of that and will give

Windows dev machine setup

It is recommended that you install "Windows Terminal" from the Windows Store to get a more sensible terminal experience. Be sure to visit the "For developers" menu in your Windows machine settings and toggle some important flags:

Change settings to show file extensions
Change settings to show hidden and system files
Change settings to show full path in title bar
Choose the default terminal app (I suggest "Windows Terminal")
Change execution policy to allow local PowerShell scripts to run without signing. Require signing for remote scripts.
