Silver loaded epoxy..where?
Anyone know of a cheap source of SMALL quantities of silver loaded conductive epoxy for sticking microwave leadless diodes in place? Most suppliers seem to sell it by the bucket load at huge cost and

Jupiter-T Signal aquisition
You could engineer the RS232 output on the module ...I think it needs a MAX232 device ...and then use a downloaded prog off the Internet, like Syntac, to monitor the NEMA output which will show on is
