Tell us about yourself!
This is one of the applications that the notorious 555 was designed for in the first place, and that it is a good design is proven by the fact that it is still in production after almost 50 years ! ;-)
Neat Idea !
There is nothing ¨digital¨ to your design, the LM358 is just a dual analogue opamp !Also the diagram is a bit straggly, if drawn from left to right (and top to bottom) it would look much better and be easier to understand, and power lines in a small diagram like this are no overdoing !
1. First make one with a pot2. Adjust the pot to the desired level of sensitivity3. Measure the upper and lower value of the (disconnected) pot4. Replace pot by two approximating resistorsand Bob's your uncle !
Sorry, but I see no milling here !Milling is the machining process of using rotary cutters to remove material, have a look at: https://en.wikipedia.org/wiki/Milling_(machining)

I completely agree with your warning and think your reaction is the only sensible one to this hazardous "Destructable" !
Paper Mache Class
The only thing I found on this page is a component diagram, do you have a real schema of this project ?
Many thanks for the data.
It would be nice to have info like estimated size and diameter (top and bottom) of cup and angles of cuts (related to top rim). I tried to make the thing but it came out unhandy (probably due to wrong size or angles).
Instead of vinegar I use a few teaspoons of Tartaric Acid (purchased from a local drug store) diluted in some water, better result and no odour or taste residue (this can also be used to clean a coffee- or tea-maker).¡ Beware of using glass marbles to prevent building up (as mentioned below), the can break into small an sharp pieces by the heat, better use a steal (bearing) ball !
I already tried that, but than it takes much much more time than 2 minutes and it still gets burned inside before it is done on the outside. :(Could it be caused by the fact that my microwave is not working on a lower constant power but is switching on and off (at lowest power it switches on for 3 seconds and than off again every 30 seconds) ?
When I try this recipe the cake gets burned black inside but stays raw on the outside.Does anyone knows what to do ?
