Really good?
Who says?
How about a display module that uses deeply embedded filament lamps for various rather important indicators on a combine harvester. Dealer claims the unit can't be repaired and has to be replaced at a cost of thousands of pounds - in a week's time.
Well, the small engineering firm I used to work for made some discoveries. It became obvious that the reason the lamps were so deeply embedded was to stop people taking them out - but that was solved with a bit of rubber hose and a vacuum pump - they were ordinary bi-pin ones, only not quite ordinary. the pins were slightly thinner than normal and slightly further apart.
We solved that problem (and the deep embed) with an LED and a resistor - also resulted in a much brighter display.
Oh and as for the 'short' working days, round these parts they harvest well into the night using high powered searchlights attached to the machines.
Biting the hand that feeds IT
