PCB for MEGA SUDOKU is done! It's 8" x 5.3" !
They're bigger than I had imagined.
I might have to get smaller displays to make the custom PCB affordable. :-(
I've successfully individually control each segment of nine digits using two shift registers. I still need to implement POV so more than one digit could "appear" to be on at the same time. My current path is to have one shift register (and transistors) to drive the column of digits, and nine more shift registers (one per row) to "draw" the desired digits on each row for the current column.
Code in progress is at GitHub. Videos coming soon at my YouTube channel.
There are a lot of nice LED segment controllers out there.. check out the TLC5920, HT16K33 and more! It can also be cheaper to make a bunch of small PCBs an connect them together vs. one giant PCB.
great project man. you know i said it will look so cool it should be acrylic or epoxy dipped .
protected and guts visable .
Saw your project on youtube, any progress yet? Any ideas about a case/cabinet to house the game in? would be a cool coffee-table-game...
Oh that would be cool! As big as the displays are, they're not quite coffee-table sized. That's a great idea though...
My current plan is to make it a handheld. It's the size of a large iPad.
As far as progress, I've been learning EasyEDA PCB software because the EagleCAD that I have had cannot handle the large PCB without purchasing the next level license.
Building a Sudoku device has been on my backburner for a long long time now. I actually bought 100 pcs small top-view nixie tubes (not sure if it was IN-2 or not, all my stuff are boxed up and put in storage) to build one with a nice retro orange glow.
But as usual a bunch of other projects got ahead in the queue of things-to-build. Maybe one day... If you finished yours maybe I feel compelled to make mine ;-)
I love it! Keep up the good work, I can't wait to see your game completed.

Great project. Just one questions: what is that IC on the top of the breadboard?
