    Hi Burt I looked at doing one & by the time you get any probes & features the cost is the same if not more to do :(

    if you are looking for basic on off stuff you could build some thing cheaper

    yes there is a way, you can use an old pc, right the software yourself and use a PC board 8 way relay control board to control analog and digital devices.
    i am using one of these Parallel Port Relay Board
    and custom software i have written. there are plenty of options, one is ardunio boards

    Thats a good idea Dallas, using an PC to do the work is a much better option than trying to build you own free standing unit.

    Yip, it probably would be.

    and for a Programmer like yourself, I'm sure you could write some nice codes to allow viewing over the net etc.

    Vatso, without saying too much, I've actually built a controller which I'm running on my tank, worked out alot more than I intisipated. The problem comes when you want to have PCBs made, unless you can do them yourself they not cheap, and to do them yourself, you need all the equipment, never mind all the fustration when thinks don't work out as planned.

    If you wanting to do something like this, the method that Dallas mentioned would be the best.

    I went through the same as you started adding all the costs & then had a lego set by the time I was finished price vs function was not really worth it.

    to control simple things yes it's a good idea DIY like switch this & that on & measure temp as soon as it's PH & Redox & & & it's just a mess

    well my pc cost me nothing i had it already, same for software
    the board cost me R300, and 8 more relays cost me R400.
    the multiplugs for 2 were R120, and all the other stuff was about R300
    and i have the same features, plus i can control via email and sms

    i can test for temp, ph, orp, or any other probe that is available etc.

    Thats the thing you can't say well the PC was free - what would it cost if it was not? & how many people can program & do what you can? what would it cost if you charged to do this including hardware?

    Thats what we need to compare

    well any pc with a parallel port, so from about R3000.
    i use an old pc about 5 yrs old. i am thinking about selling the software, and prob would give it away for the first 50 clients etc, i am in the open-source areana...
    but if i have to make a serious product etc i am sure i coould sell the whole thing for under R4000

    Yeah that Arduino Board has some pretty cool capabilities. And coz its open source there are plenty of programs that have been already written and loaded onto their site. The crux comes in where you want something specific for your tank controller. In my opinion if you've got a little know how and some professional advise (aka Dallas) you can have a lot of fun. Plus its customizable to what you require.

    I want to use an Arduino to do some home automation stuff - already been chatting to some guys who are using PIC for their home automation.

    the secret to home automation is choosing the right relays for the jobs required.
