Low-cost Talon SRX computer?

[Greg McKaskle]

Your project is still shrouded in mystery, so my suggestions may not be that applicable. Here are my tinkering $.02.

1. The cheapest stuff is what you already have.
2. SRX are quite nice, but it is not hard to do PID on almost anything, and you'll learn and understand it better if you can see the response plots and understand what the control terms do.
3. A key part of engineering is transferring from a scale prototype to a full implementation. Or from one domain to another. You don't have to meet all constraints at once, especially if this is risky, so using a laptop and building a big one with the tools you have may be the quickest way to prove it works.

Then take what you learned and grow/shrink speed it up, make it cheaper, etc.

Yes, you can skip these steps, but many times, the optimization and lack of iteration drives you off course and gets in the way of other discoveries.

By the way, CTR provides non-FRC firmware that has no tokenization for safety.
