icchalmers/WordClock_v2.02This is a work-in-progress build of a word clock. It was originally my final project as part Fab Academy 2015 at Fab Lab Strathclyde. You can follow the inital evolution of the clock on my class website.
PowerDistributionBoards is an open-source printed circuit board by icchalmers, from the icchalmers/WordClock_v2.0 repository on GitHub. It is a 2-layer board of 209 × 209 mm with 35 parts on 36 nets, routed with 145 tracks and 0 vias.
Its parts include 22 ICs, 8 connectors and 1 capacitor.

This clock is an evolution of WordClock_v1.0.
The 'Model' folder contains all the Autodesk Inventor 2015 CAD files for the clock.
The file Model/wordClock.ipt is VERY customisable, but has no mounting holes for electronics or any mechanism to support the LED strips.
The 'Model/SolidifiedClockToMake' folder contains a locked down version of the clock i.e. it uses a grid of 11x11. Some parameters may or may not still be adjustable. It has additional holes added to the middle plate for mounting control electronics and holding the LED strips in place.
The main file for the clock is wordClock_NonParametric.ipt. The other .ipt files are the individual pieces and are derived from wordClock_NonParametric.ipt. They have been compensated for laser kerf using the "kerf" parameter in the master model.
The file PartsForExport.dwg has a layout of each of the individual parts. If you change a parameter in the master model, update the individual parts and then update the .dwg.
The lettering is added in CorelDraw - Inventor is a bit rubbish at handling text. I used a modified version of Source Sans Pro i.e. I added little structures to support the internal parts of letters.
The 'hw' folder has the KiCAD files for the two PCB designs: the main control board and the power distribution boards. The power distribution boards also help hold the LED strips in place.

35 parts. 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.
From the icchalmers/WordClock_v2.0 repository on GitHub, at the commit this page was made from: the board is hw/PowerDistributionBoards/PowerDistributionBoards.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask icchalmers before reusing the design.
