Sorry about the missing videos, I deleted my youtube account...
There's been a few updates with this project anyway and more to come too.
The interface is now handled trough touchscreen + PC (the LCD + arduino's keyboard are still there for backup, but not for long, it's so much easier to do things trough Meguno). MegunoLinkPro just came out with a new version of their Interface Panel http://www.megunolink.com/
. I just had my 1st go with it and it's just great, ok, there's a few minor hick ups still to fix and the documentation is on the thin side at the moment, but still big thumbs up for them :
I need to add another page or tab for all the mash temp settings etc.
Here's how it looks in the real life:
The plotting has improved too since the last pictures I shared in this thread:
Another cool gadget that I've added to the system is a scale under the mashtun. There'a a small amplifier/AD-module available to the Arduino that makes it easy to do this. http://www.elecrow.com/sensors-c-111...711-p-715.html
I used load cells from a cheap digital scale, they work just fine. It's a really accurate way to measure volumes, a lot better than the flow meter that I used before (it had to be calibrated, if the flow changed). The plywood triangle is the scale:
I can measure the grains with it too and I guess I could calculate a ruff estimate how efficient the mash was based on the weights before and after it.
The HERMS is now CF-HERMS and it's controlled with PID's (Arduino), but that's been covered in the other thread.
