Hello All:
There are several electrical noise based random number generators, but most
were concieved in a time when there was a lot less EM pollution of the
airwaves. There are no magic/secret frequencies any more. I got into
time-nuttiness from an interest in Radio Astronomy, and all Radio
I like to use a site called www.findchips.com It searches 21 US
distributors for parts. It's billed as a finder of ICs, but it works well
for anything electronic with a part number. No advertising, no frills, just
gets the job done.
Unfortunately, there are a lot of parts that start with the
A really good way to handle the pad on the bottom of the part is to put a
hole through the board right there. You usually need a bunch of vias to tie
the pad to the ground plane on the bottom of the board anyway. Put one hole
large enough for your soldering iron tip to reach in and touch the
My usual choice for dual schottky in an SOT-23 is the BAT54. It comes in
four flavors:
BAT54 - single diode
BAT54A - Common Anode
BAT54C - Common Cathode
BAT54S - Series
It's rated at 30V/200mA.

The NTP built into Windows is very poor. A couple of the versions are not
even compliant with the standard, and some servers will reject their
requests. You have to use better client software, at least for your master
controller.
The CMOS clock only matters when you lose power. NTP should only

I highly recommend this magazine for all the tinkerers out there.
