Hey Guys,
I hate to spam the list like this since I haven't posted anything in a long
time, but I know you're a good group of people. Times
are tough and it's time for me to sell off some items that I don't really use
or need. I would rather have these items find a good
home and just break
All of the PICs I ordered came in on Friday (Mouser ships FAST!) so it's a
matter of programming them and getting them out this week. Just an FYI
guys, I'm leaving for southern Arizona for three weeks for work. If I don't
get them out this week I will do my very best to get them out while I'm on
Here we go again!
The TS272ACN has just gone 'non-stocked' at Mouser. Will the TS272CN
degrade the performance? It looks like the difference between the two
is the TS272CN has a higher input offset voltage.

The TS272CN is an acceptable substitute for the TS272ACN in the
PICTIC II but as noted has a higher input offset voltage. This
can be compensated for in the second stage by adjustment of
the offset trimmer. I selected premium parts for temperature
stability in the application. Sorry the
Hi Richard,
Yes, used to feel that way - until acquiring a surplus dissecting
(stereo) microscope, now I actually *prefer* surface mount. Much
easier to move parts around, it's easy to apply paste solder entire
boards in a $50 toaster oven, and access to all the latest parts.
Hard to
Not to mention not having to drill holes anymore. I built a 15Ghz
prescaler over the weekend. Total time from concept to completed (and
operational!) prototype was 2 hours. No muss, no fuss, just design
the circuit, print out the toner transfer, paste it onto the board,
etch, apply paste parts,

Hello. I'm new to this list but have 3 Rb standards and am looking at
measuring time (or drift between them). What is the most important piece of
NIST calibrated test equipment I need to own? Is 3 enough using two Rb
standards as a reference/control group (considering the 3rd can vote before
