Ok, ive been sitting on this idea for a little while, but its finally bugged me to the point that i want to do something about it: I am incapable of grinding the precise amount of coffee every time. I just cannot do it. Ive been assessing my solutions. Weighing up the perfect amount to grind every time i pull a shot? Too time consuming. Using the gaggia MDF "doser"? nowhere near precise enough.
So, I have come to the conclusion that there is only 1 way to go: I need to find or build a timing circuit that i can use parallel to the existing grind switch in order to ensure that i get exactly the same amount of coffee grind every time.
Specs?
needs to be powered by 240VAC;
needs to be able to drive a decent load (will need the ammeter to check how much current the grinder pulls - will probably need an ssr);
need to be able to adjust the timer as required (pot with a knob)
need to be able to override the timer for "just a little bit more" when setting the thing up (hence parallel with the existing switch)
Put simply, i want a little box with a soft touch button that i can press once that will set off the grinder for a period of time that i can adjust, and at the end i will have exactly the same amount of coffee grounds as i had last time, and will have next time.
Being home to a small crew of dedicated modders, i though this would be a good place to post my general idea, and hopefully with the help of the more knowledgable types i might be able to get this idea off the ground.
So, please, your help is greatly appreciated

able to switch up to 750W; or this one -
able to switch up to 2,000W, and if youre feeling particularly geeky, you could make your own from an old microwave front panel as per
