The bad one
Well-known member
Was doing a bit of pottering tonight looking for some connectors to fit my computer speaker up on the wall in what passes for my office. On the bulk(why's it called a Bulk? No idea at all!) above the stairs I have boxes of electronic stuff, wire, resistors, project boxes, pots,buzzers and many more electronic things that haven't see the light of day for many years.
Not since I stoppedmaking all sorts of electronic pike back biters and conversions forall manner of electronic bite indicators.
In the box I cameacross these, that I kind of knew I still had but couldn't have toldyou where.
Anybody remember them?More to the point still use them?
These two I modifiedfrom the original Optonics, the ones with a short wire from the headto a sounder box that was best used open to hear the GPO speaker.
These Optos really got beaffed up, the buzzers in them are 110 dbA buzzers, bought from Maplins Electronics when their shops were specialist Electronics shops. The nob on the side is a volume control pot as the buzzers would wake the dead when they went off.
Did I find what I originally went looking for? No as with all pottering I got sidetracked with all this fascinating stuff I rediscovered :confusion:
