I can't say you're wrong, but is there a person who more than 50% of citizens would actually be happy to vote for? The options we're presented aren't great, and I'm certain a better one could be chosen. But reaching a full 50%+ seems like a tall order in the current political environment.

I could be mistaken, but many years ago I believe I learned that plywood is generally made by spinning a log while slicing a thin veneer off the surface, then stacking multiple of those veneers into plywood. The grain on the surface would be notably different when cutting wood with this method compared to sawing planks

I'd also like to hear what your idea is. I don't know of a platform to solicit someone building your device at a price you'll be wanting to pay, but there are forums to help you learn how to do it yourself if you're motivated enough.

If it's cool enough to pique interest, you could try posting the concept in an electronics community and seeing if anyone's interested in the challenge, or an ideas community and just floating it for people to choose to run with.

It's also possible the device already exists and someone can suggest an easy option for you

Well, I'll admit it might be poorly suited, but I know it supports comments, posts, and user signups. Users would sign up with a sbscriber role, you'd verify them somehow, and then you'd update their role. It would be a little janky but should work with little adjustment

Easiest? I'd say WordPress on a Digital Ocean droplet if you're going super small. Allow people to sign up and vet them, and you have a functional standalone platform pretty much as soon as you can get users. I don't know that it would take off or have a sustainable userbase though

If you are able to function independently, then you probably won’t be clinically diagnosed even if you have some struggles here and there.

I disagree. I have official diagnoses for both ADHD and ASD and am mostly functional most of the time. If I earned enough, I'd be living on my own. I was diagnosed as an adult within the past few years while working nearly full time and I made it on time to each of the several appointments that went into getting that diagnosis. If what you say is true, I doubt the assessor would have been willing to give a diagnosis.

Thanks, that's good to know! The datasheet doesn't seem to include the word "duty" anywhere, so I think that must have been omitted. Ostensibly that means the maximum duty cycle is unlimited, but I don't have enough experience here to say that with any confidence.

Thanks, I don't think there are any external settings for the power supply, but it does provide a few more volts than I strictly need. Toggling a single relay hasn't caused me any issues in the limited testing I've done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I'm getting dangerously close to the upper limits for the power supply's current rating. I'll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.

I haven't worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.

With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I'd need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.
