openclock

A clock designed to resolve the flaws of every annoying alarm clock that I've ever owned. Large display that can be easily read with uncorrected vision, adaptive brightness based on the time of day, intuitive touchscreen interface, clear feedback on the state of the alarm, intelligent alarm audio. Powered by Arduino. A work in progress. Journal of effort to date at http://clock.bonsignore.com

Questions

How big is the TapMatrix PCB?

It measures 68.6 × 53.3 mm and has 4 copper layers, 1.6 mm thick.

What parts does the TapMatrix use?

31 parts, built around the 74LS125DC, MCP4921-E/SN and DS3231S#. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the TapMatrix KiCad files?

From the cbonsig/openclock repository on GitHub, at the commit this page was made from: the board is kicad/tapMatrix_Slield_4layer/tapMatrix.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the TapMatrix design in my own project?

Its repository states no licence, so its author keeps all rights: ask cbonsig before reusing the design.
