Hi all,
Here's some links to info on this new single channel serial ADC, its a
little over 4 bucks
in Digikey.

Looks kinda neat, I'm going to try to get to it next weekend.

:Hi Mark,
:
:> Trouble is now the '530 won't go off.
:>
:> I put a 150k pot in series with a 100 ohm on the emitter side to try to
:> crank down the beam a little, but '530 still won't turn off relay.
:>
:> The 150k pot maxed out makes the OMRON give out a 3.5v signal, but then
:when
:> I break the beam the signal goes back up to 5v?!?!?
:>
** I am not familiar with the OMRON or your circuit, but the '530 should
:turn off if the Stamp pin goes low.
:
:> Strange about the ESD, its raining here now, somehow I always thought ESD
:> was mainly a concern in dry weather.
:>
** That's true, rainy weather helps stop ESD, but humidity could still be
:low if the furnace is blasting, or you have a chair like mine with covering
:material that charges big time when I get up.
:>
:> Seen those new MCP3201 one channel 12 bit serial ADC's? Little over 4
:bucks
:> each. Seems like a real winner for the BS2.
:
** Thanks for the tip ... we will check out that part. Right now I am
:using the LTC1298, needing one channel only, which costs $9 from Digikey.
