There is already a kit [1] for a 555-like circuit (I think Dave [2] says there's some reason it can't be used in place of an actual 555) made of discrete components.
But there's no indication that it's Open Hardware, though. :-(

- pjc50 12y agoNice teaching tool, but even if was electrically identical and Open there would be little point in using a de-integrated circuit in actual production, surely?
- jpwright 12y agoThere's a really detailed description of that kit (including full schematic) here: http://shop.emscdn.com/KitInstrux/555/555_principles_revB3.pdf http://shop.emscdn.com/KitInstrux/555/555_principles_revB3.p...
