I made this DIY kalk dripper for dosing kalkwasser. I got the idea from this link:

I just finished it today, this is draft #1 and i used a pepsi bottle as im not done drinking the 2.5 gallon jug of water i planned to use . Heres a few pictures of the finished product.
The total cost on this was something like $5 compared to the $30 i was going to spend on a kent version.
