    hackaday.com 29 Jul '14, 2pm

    While it’s almost cliché to say they don’t make things like they used to, this week’s Retrotechtacular offers fairly conclusive proof that, at the very least, they used to put more time and effort into manufacturing consumer electronics. Gather your homemade wisecrackin’ robots and se...

    Used to have a larger-scale one of these in my scout troop that we would take to events and have for little kids to come make rope — fixed-length at the start of construction (you ran twine back and forth and hooked it into the machine, then tied it off, IIRC), not spool-feeding like ...
