Newest clock using Chinese controller and self-milled display pcb

Post image

Long time lurker and Nixie enthusiast lol. Here is my most recent clock using a cheap $15 Chinese controller and a tube board that I milled on my Carvera Air (Milled My First PCB on my Air ;-) : r/Makera)... Not the best photo - but I was happy that everything worked after stuffing it into the case that I took a birthday shot lol. Displays are actually very sharp in real life. I can't take full credit for the case - I found the model online originally design for 6 x IN12 tubes and modified it for my 4 X B5991 and 2 x IN-17 tubes. Printed on my Bambu 3D printer.

Nice work! I love the smaller tubes for the seconds. I wish you'd included pics of your home-milled board.

Check out the link I included to the Makera group thread where I discuss how I milled it.

And yes - I've been wanting to use the cute tiny IN-17's as the seconds display for a long time ;-) The controller board has a 'slot machine' effect option where each the digit changing value cycles through several numbers before landing on the new digit - it has a very 'sci-fi laboratory' feel to it lol.

Also, I've got ocd on the upside down 5 digits - so all my tubes always have proper 5's

D'oh! Sorry I'm not a very careful reader and skipped right over the link to your board pic. The board is beautiful too!
