A control head from an ancient Brother BAS-311 sewing machine emerged from a recent Squidwrench clearing-out session:
The sturdy metal enclosure ought to be good for something, I thought, so I rescued it from the trash.
One of the ten button-head screws galled in place and resisted a few days of penetrating oil, so I drilled it out:
The PCB has no ICs! It simply routes all the LED and button pins through the pillar into the sewing machine controller:
The ribbon cable alternates the usual flat strip with sections of split conductors:
The split segments let it roll up into the pillar, with enough flexibility to allow rotating the head. I’ve seen segmented twisted-pair ribbon cable, but never just flat conductors.
Maybe the control head can become Art in its next life?
