PID questions

[Lampshade]

I used to use Omron E5CK Temp controllers for near everything. The PID is extreamly smart, and has a communication channel for multiple settings. You can pick them up off ebay pretty easy, I've managed to get most of mine for < $20. Any questions let me know.

Heres a link to a spec sheet:

This Arduino looks intriguing.... I'm going to have to look into it further

If you want to try the Ardunio (or any other micro), you can got to my old company (still being run by someone else) here in Calgary so you don't have to deal with international shipping:

Dude, that's a whole website of fun you got there! who needs to shell out $200+ for a tank control system when I could shop there.

I heard rumors that they are giving away free Arduino to Canreef-ers...

Weeellll...it's just a different form of addiction. If you ever thought it'd be cool to own an aquarium-related business, let me tell you: if you love it that much, don't do it as a biz ! I was nuts for the electronics thing; started and ran that company for 10 years and in the end wanted nothing to do with it.

I still have a lot of equipment and tools but I still dread it a bit. I'm thinking that I'll eventually warm back to it and a fun project controlling parameters of a tank could be just the project to do that.

hmm I'll check thing out.. I was just in victoria for the last 4 days so I just saw these

Ok, so I have been looking, and frankly I am not sure about the Arduino because of the programing thing. But if I was to go with the Arduino, what all would I need to buy for hardware.

here is the requirments.

two temp inputs two controled outputs (one 1200 watt element and one 100 watt element)

some sort of display which could show curent temp, set point and meat temp.

now for function it needs to
-maintain the set cabnet temp by use of the 1200 watt element.
-adjust cabnet temp to predetermined set point when specific meat temp is reached.
-allow different types of programing for different cooking styles. say doing a spicif temp for 2 hours then adding 10 degrees per hour till another temp is reached then hold at that temp.

I also need it to be able to turn on the 100 watt element when a specific cabnet temp is reached.


Now I don't know how much it would cost to have but wireless ability so I can monitor/controle from my laptop would be nice. but not nessaray.

so how much would it cost me to get all the stuff I need to do this?
