Very nice work, that is so clean wanareef, I've seen some nasty ones out there, like the ones I use to diddle with long ago! I'd like to see the functions & what it can controll as compared to the already premade units you buy.
"Well, the way it is working out currently is you will have up to 21 outlets controllable by anything on the controller...16 X-10 outlets and 5 direct Relays.
So you can have fans, heaters, pumps, lights or whatever controlled by Time, Date, pH, ORP, Tank Temp, or Room Temp. So you will be able to set it up however you like.
Hope that is good news...
"Well, the ballpark is still under construction lol, but my best guestimate at this point is about $75 to $125 if you build it from the ground up yourself. This does not include the $30 internet interface or the X-10 interface(also about $30).
The code is coming along...don't hold me to this, but maybe by mid January the main code for everything except the internet interface will be finished. Then Mark is going to lay-out the actual board.
What amperage rating are the relays, or is this something I can add myself? That sounds awesome, and better than the pre made, as long as it can handle the power of all that equipment loaded. I'm guessing you will also have to sort of protection built into it, breaker/s or fuse/s. That is the type of controller I'd really be interested in, I was thinking of buying a PLC and let one of out programmers do the logic for me, I'm sure I could twist their hands into this neat project, I'd also wanted to add an HMI, it would be so nice to have direct access, I could do the graphics myself. I really like what I've seen so far & can't wait to see the complete package, The Internet stuff is cool but I'm not as concerned with that as much and the control system itself, remote access later can be dealt with but glad your planning and leaving room for it also.
I'll have to dig into that, I thought they were 20amps but could and probably am wrong. If you look on his home page, about 1/4 way down, he has a site for q&a or you can email him here: Kevin Carson <email@example.com>
I was never the eminjeer, just a draftsman that redrew schematics and did board design- when I was in the field.
Ok, thanks! I do a lot of drafting also, I'm a high paid cad operator or Electronics designer as they call me, lol with a electronics technical degree, I've been working with Electrical engineers about 16 or so years now.
Hey not lookin to steal the thread but.........Do any of you Big Dog engimineering types know of a "Simple" pc drawing program? I'm just a sheet metal worker with basic PAD (pencil aided drawing) skills. I'm trying to draw the plumbing for my 150 gal.
