This old 24-pin dot matrix printer has been converted by some boffins/guys with too much time on their hands into an oddly awesome speaker.
You might not be old enough to remember the old school days of noisy printing, feeding in paper with holes out the side to the chattering noise box. Tearing off the paper from the edges was always an enjoyable, if not terrifying experience. Remember when you ripped past the perforated holes directly into the important document you’d just printed?
Anyway, watch on below for Survivor’s Eye Of The Tiger played via a MIDI file via the printer. Hobbyists, engineers and those also with plenty of time on their hands, read on right down the end for the more detailed explanation.[via]
