I'm all for Andre-K's idea.
I have lots of spare parts, electronic components, etc.
I can hack in a logic converter, or a power supply, or pop it open and solder a jumper, or a cap or diode or whatever...add whatever component is required - if it's possible. I'd even help with the instruction to do so.
My issue with cost, is that I have a perfectly fine, stock factory Solo.
I don't much feel like paying 170 US to test, and waiting 2 months for the thing if I did.
I guess in the end, I'm hoping the intention for the Solo on Master project doesn't require us to do so. If that's the intention, I'm thinking you have a pretty small group of people you're doing all this work for, but that's my opinion
If the intention is to actually use the stock PH2, even if a bit of DIY work is required I'm thinking you've got a good amount of folks who'd be willing to use it.
I'll willing to help anyway I can, I've been putting my craft at risk, and on more than one occasion, crashing them, for a bit of time now. That's not my issue.
I can't contribute much otherwise, and there doesn't appear to be a large amount of people willing to risk it.
I'm happy to do it for what I'm receiving out of it. Just don't wanna pay another $200 to do it is all I'm saying
