have you got one clear light I would love to know
if they give you enough info to code your own interface.
dont want to use there code if possible otherwise I will
make my own.
not to expensive either.
nice one :)

remeber its not about the drugs mate its about the music

  Yes I have one, actually more than one... they are very slick, program in basic, there's a ton of stuff on the web, check out the site... you can do just about ANYTHING with them... I build instruments and use them for the A/D conversion and stuff.. one of the one's I'm working on is a temperature/vaccumn controller with gas inlet that will allow you to run your pump full bore, adjust the picoliters of gas you need to keep a constant pressure, and take the temp off the condensor head... push a button and you get the  time/temp/pressure for your fraction...I call it a fraction cutter... $19.00 for the pt temp resistor sensor, I got the absolute vacumn gauge as a sample ( normally $45 ) and the picoliter air valve is about $75.00. LCD screen runs $7-125 depending on how much graphics you want...

  Use fuzzy logic to code it, so you don't have to do PID loops and other nasty differentials in your code..

CL: When your design is finished, I'll GLADLY buy one of those things for you!

I dont like basic much though :)
it does seem to be the way most plc's go though
its just so limited when you want to hook it to other
peices of software like sql servers ect.
were do you get vacum gauges from ?
and do you insert your electronic therm in a glass tube
or some other way.
found a site full of schematics dont know if it
is of any use to any one but what the heck

thanx CL this will save me a heap of time :)

Sql Servers???
« Reply #45 on: May 24, 2002, 07:42:00 AM »

  Right, well then you'll buy a board on a chip, but hey, wadda ya wanna do? Run a server farm or collect data...besides access is easier to program than sql, and you get it in office...can't get sql for free anymore...

 Vacuumn gauges are all over, omega sells a bunch, and then you can try sensym as well...

  Therm is in a sand packed thinwalled glass tube, use the 3 wire so you can measure accurately...

Want a cheep source of rugged, solvent-resistant 12V solenoids? look no further than the junkyard. Fuel injectors! They can be triggered by a square wave from a one-shot timer for any length of time. If timing is real critical use a power transistor instead of a relay for switching the 12V power from the 5V signal pulse.

That paralink product is about too cool! Been wanting a lot of instrumentation and control equipment and a couple of those daisycahined to my PC via RS232 is just the ticket. Since the documentation and software is free all you gottas get is the board of your choice and add some programming experience and WHAM .... automated  lab!

The product is really good and the documentation is great

Thanks dude!

I dunno, but I been told ... You never slow down, you never grow old!

These articles on automating various operations in the chemical laboratory will undoubtedly help many bees  ;)
