Hello, I agree with s.b on the principle of searching for yourself (at the beginning) but nothing prevents you from asking for advice, technological evolution is the product of communication, the smartphone was not invented on a single worktop...
The priority is to establish specifications:
- Function of the machine: we get it, cracking almonds
- Financial means: don't go for a solution that is too expensive if you are only a student unless you want to make it drink but between us a good nutcracker is enough for the average person so avoid a product that is too complex, it has little chance of being marketed on a large scale unless it becomes multifunctional.
- Motorization or not: Do you want to make a product like Senseo with two buttons or manage a system manually?
- Observation of similar products: today there are a bunch of nutcrackers or almonds on the market and it costs nothing...
The question you need to ask yourself is: What can I bring to this product in addition?
My idea for you would be to make it an element to incorporate in the kitchen, discreet and linked to other kitchen utensils all usable on site or dismantled for "portable" use
An example: a small tower with corkscrew / nutcracker / pepper shaker etc. all dismountable.
