Automatic swear machine
An ingenious and practical invention shared by IMGURian @GuzziGuy.
The post became so popular, that the maker has decided to offer them for order from Etsy.
I realise the price is a bit high, but there's a lot of work and materials in it, it's as sensible as I can make it!
About the making of:
Read the restThis is a project that goes back a while. About 9 years ago, I got interested in nixie tubes and built a few clocks from kits; during which I learned of the FLW - Four Letter Word, a toy created in the 70s using huge B7971 nixie-type tubes. The original creator had made a new, updated kit - which I ordered (and obtained the tubes elsewhere), but he went AWOL (causing some drama in the community) and it never arrived.
So worked on my own version with an Arduino - and got it running, but ideally I wanted to make some more for friends etc but a) my electronic skills were not up to converting my breadboard into a PCB; and b) the tubes were expensive even then and not practical to obtain. Not to mention that by then, other folks had made this better than I could. Project shelved, indefinitely.
Cut to late 2019, when I discovered Scott Bezek's split flap project. A lightbulb moment - a splitflap display is arguably the only thing cooler than giant nixie tubes; I'd always wanted to make something with one, but new or old ones are difficult and/or expensive to acquire.
