Does anyone know some simple and cheap microcontroller with two
RS232-interfaces and perhaps also a CAN-interface?
Often you can get a cheap mc but have to pay a lot for the development
tools which are of course needed to write software for the

I'm tired of people mooching my resistor supply.  I'd like them to
get their own.  I thought I had a lifetime supply; now I'm gonna have
to die a lot sooner.
In searching for resistor 5% 1/4 watt assortments, I find two kinds.

I'm looking for the name of a particolar amplifier, if it exists, that
has a saturation voltage different from voltage supply.
In particular, I'd like to set this saturation voltage externally...
Does anyone know if a components like this really exists?

Brand new parts, in original anti-static tube. Minimum bid
1 dollar each, buy it now for 2 dollars each.
100 pices of this part sells for approximately 2.66 each at Digi-Key

Anyone know of any solar cell vendors that sell
solar cell modules that put out 6-9volt @ 100mA?
TIA,
Remove "HeadFromButt", before replying by email.

I see ads for wide-bandwidth amps with what seems like very low noise
compared to the amps I'm used to.  For instance, I just got an email flyer
from TI touting the OPA695, a CFB amp with 1.4GHz bandwidth and 1.8
nV/root-Hz.  Contrast that with the OPA134, a low-noise audio opamp at ...

There is a stockist out there who owns a stock of old custom
chips (ULAs) that were used as a memory controller and CRTC in
an old, relatively obscure, 8-bit microcomputer).
He asks 8 euros apiece.

My neighbor brought his 25A (12 volts) power supply over for repair
last evening. I found the bridge rectifier shorted and one of the 2
pass transistors shorted. The 20A fuse in series with the output was
not blown, the 4A line fuse was blown.

I need to replace a M5229P graphic equalizer chip.  Basically it's
just 8 opamps with internal resistors configured so that 2 pins of
each amp connect to the outside world to make inductance gyrators for
a filter bank.  Here is a diagram:

*** Semiconductor Data Books -- Mostly like new.
 Probably can't order anything from these but,
they may be useful to service a 2nd Millennium relic

I'm looking for a laser diode driver IC, SMD, minimal external components
For use with 10mW 3 terminal diode with feedback photodiode
Dont need modulation, just constant current

I'm loking for a supplier of 37.9kHz IR remote control receiver modules that
will run from 3.3V supply (90 degree legs if possible). Suitable ones
include:
Vishay TSOP34838

The part number I need is Hitachi HM628128LP-7 or equivalent. I'm
looking for 24 pieces.

Looks like this lot of transistors is gonna be a high dollar item on
Ebay.   Only ten yours left, tho, so get your bids in real soon.  ;-)
Yeah, right....
