Polling list wisdom here...
Hmm, any suggestions for anything creative to do with around 450 or so
5V relays? I have a bucket full here (literally).
Form? Contacts? terminal type?
I can't help thinking I should be able to wire up some sort of
interesting computer-esque demonstration with them! (Something nice and
power-hungry, noisy, and with plenty of obligatory status lights :-)
Yes: Let's postulate that your bucket is populated with a Generous
Quantity of 5V 6PDT relays with sockets. Look up the schematics /
articles for the Simon Relay Computer from (I think: others will please
correct me) a mid-50s issue of "Popular Electronics", or "Electronics
Illustrated", or maybe even "Better Homes and Electromechanical Brains",
or some such periodical... anyway these relays would make a dandy Simon,
or two, or perhaps a Simon with a Relay Floating Point Processor....
If you use sockets and a PCB layout program like Eagle or ExpressPC -
you could even eliminate most of the tedious wiring - depends on just how
'authentic' you wanted to get.
