    Hey Guys

    CivEng grad interested in building small wind turbine. How tough would it be to build (or how much would it cost to order) one of these

    No idea because you're in the wrong forum :o Off you go! :)

    Apologies in advance if this is too electronic-y for you Tom/muffler, shove it into Electrical or somewhere if need be :o

    Oh, and as for "order" if you mean get a small wind turbine, oh, only €1200-2000 plus installation! :eek::eek::eek::eek::eek::mad::mad::mad:

    If you mean the PCB, well, I'm guessing it would be €50-100 for the board if they were being produced in actual (small) volume and €100+ for board + components, higher still if you wanted it assembled. And you'd need to find someone producing (or willing to produce) these DIY DC generator controller modules in question first! :o:o

    My wind turbine came with one of these low voltage controllers with op amps and so on on a board, but I'm in the process of chucking this and writing a programme for a PLC instead.

    I first started using the PLC as a controller for a turbine we were designing, and as I got to use this I realised that for about €100 you get a fully programmable system with relays, gates, voltage comparitors, timers, boolean logic etc., giving much more flexibility, so I'm retrofitting one onto our other (24V) turbine at home. You also get the option to write menus, and the one we use has a four line LCD so you can tell the user what's happening.

    Best of all, you can customise it later without taking out the soldering iron.

    You may still need a small board with a resistance divider and capacitor on it to measure the voltage, but that'll cost about 10c for the components.

    You can get PLCs that work on 12V or 24V DC, PM me if you have trouble finding one that you can work with.
