Yeah home built and programmed smart devices are the way to go. I’m addicted to the rush of making dumb appliances automated.
The smartphone controlled aircon for $150 extra? Slap a $4 Esp in that. $400 to get sleek control of your central heating? $4 Esp. Turn on the ice maker on the commute home? You guessed it, $4 Esp.
Yeah it’s good.
This is proof of citizenship. Not drivers license or proof of age. Passport, birth cert plus supporting, citizenship cert and supporting. Discrepancy between the latter two options resulting from change of name could disqualify voters.
“Nine percent of American citizens, or approximately 21 million people, don’t have ready access to citizenship documents.”
Then you have my country where you enroll to vote, which requires id, lasts forever and you only have to update your address. On the day the volunteer looks up my given name on a ledger for my area, asks for my address and phone number, then explains how to write my vote.
not carnelian? was so close
You need electrical experience, I wouldn’t recommend anyone to work with high voltages unless they knew what they were doing. The method depends on the device, every one is different. For the aircon unit the esp is an internal remote, so I spent time decoding that model’s IR codes and building a platform for reliable control via home assistant. I have fans around the house that use mains voltage motors with 3 speeds, those got an interlocked 3 channel relay board. The ice maker used digital logic, so the esp sits between the control board and the rest and intercepts button presses to keep track of state and the injects its own commands for remote control(not my work). If you are lucky there will be a guide on the internet you can apply to your specific device, otherwise you’ll have to work the project out solo from smaller guides.
