AdeV:
It's my doorbell!
https://madmodder.net/index.php/topic,12284.msg146395.html#msg146395
I couldn't make the stripboard version small enough, whilst having the sideways pointing LEDs. Even now I've had to go for the 3mm versions... not yet sure my blue ones are bright enough, I may need a smaller resistor. I don't mind overdriving the blue one a bit, as it's only on as the bell is actually ringing.
I'm also not sure what effect having the computer bits outside the door (in the switch box) will do. They may fail due to environmental issues; but equally, I wasn't sure if the capacitive sensor would work at the end of a long run of cable. Worst case scenario, I'll compromise and have the switch/LEDs outside, a small box inside with the chip, and the long wire running back to the bell box.
I'll post a writeup on the doorbell once I've got the box sorted, unless I get a flood of PMs' saying "for god's sake nooo!" :scratch:

I think I'm excused for forgetting - it was September 2017 you started on this project!

Totally excused... I thought the forum must have it's years wrong at first... 15 months since I figured it'd "only take a weekend". Oops!
I wonder how many visitors I've missed....? :scratch: :lol:

Well I stood there pushing the bell for hours hoping for a brew, but gave up and found a cafe :doh:
