Did I hear right? There's a chance your original Herring Aid attempt may still exist?
ReplyDeleteYou've got to go dig that up and get it working! Or at least diagnose the problem.
With two cats whiskers and a winter green lifesaver you can achieve amplification!
ReplyDeletehttp://members.shaw.ca/swstuff/esrmeter.html - Just a little something for your Tek 465.
ReplyDeleteI understand that if you heat the altoid in a microwave oven for about 20 seconds, it will enhance it's crystaline structure and improve detection.
ReplyDeleteI can't believe I forgot to mention that! Yes, indeed, 20-22 seconds in the microwave helps a lot, but only if salt is sprinkled on the Altoid. The salt introduces impurities into the crystal structure, turning the curiously refreshing mint into a semiconductor. Thanks for reminding me OM!
