Seized Bottom Bracket Removal, the Knuckle-friendly Way.
Thanks for the idea. I had a lot of aluminium lying around so used that for mine. Piston was epoxy putty using the cylinder as a mould. I didn't balance the flywheel well so it walks!

Thanks for the instructable, I'm currently using this as a basis for my own clock. I'm using 4 modules, so only showing time and temperature. To save space, I'm trying to display 12h time format. I've tried a simple if statement to subtract 12 from the hour, however the display shows '09' instead of '9'. Any ideas how to modify the code to make it work? Its totally beyond me!
