#402 pips

Rolling the BoldportClub Pips (Project #23) - a classic Elektor die circuit using the CD4060 ripple counter.

Notes

The Pips circuit is based on “Dicing with LEDs” by Elektor (December 2006), but with a new PCB designed as only Boldport can (and a flash red baggie).

The ripple counter toggles through all die states at around 8.8kHz. Diode steering is used to light the appropriate LEDs for each state and reset the count when it gets to “7”. This runs fast enough that it appears all LEDs are on at the same time.

When the button is pressed, the counter stops - this is a “roll”.

This is a similar concept (but quite a different implementation) to the LEAP#229 Dice project, which uses a 555 and CD4017 to also achieve a slow-down effect.

not for cryptographic use

I think I’ve fixed that. Can I interest you in my ICO?

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
