I'm pretty good with the feature creep on ultrasonics, but not on now needing to get a building permit, digging around in walls and maybe a short trench to run wires. The building is commercial space, so it's conduit for the AC. Low voltage is easier, but will need plastic flex to meet local code.
But I'm sensing a clue train (*) here, I had come trying to get some ideas on best practices on battery power for an outdoor project. but I'm getting lots of cycle back to AC power. Should I go back and say "Sorry, this isn't going to fly since I don't have a reliable power source. Battery is a short term, you'll get bored with changing the battery packs and the bench will die."? I'd like the project to fly, but don't want to see hours sunk into something that isn't going to be really viable.
Thanks
(*) Clue train reference is from a person that used to walk up to me and go "Clue train now departing to Smartville. All Aboard" and hand me what ever document she had to prove that I was being stupid.
