I have looked through all the autodosing threads I can find and all require electricity. Has anybody built one that doesnt require any power other then gravity. Would it be possible to just use standard lab apparatus to stage a couple of 1000ml seperatory funnels above a tank with a suitably low drip rate to equal a daily dose. Other then clogging, why would this not work. I realize it might look unappealing to some but I would find it sort of attractive in an apothecary window sort of way.
