add another hole for better mechanical fixing
add local component library
opamp Schmitt trigger version
mention gEDA in the readme
discrete components and opamps were hacks anyway, rise/fall time too slow, much soldering; will make do with quad schmitt trigger NAND gates and grumble at the waste
get rid of cruft, update schematics
re-shuffle IC slots to ease PCB routing
add schematics, connector for LED board
PCBs
put both boards on the same panel
