I think the best ideas come when you make something that you really want for yourself.
In 2020, I really wanted an eink calendar to hang on my wall.
Still, many people built one for themselves and never turned it into a commercial product.
It’s a lot of work and some of it is boring. And you have to pay for certification and worry about all that paperwork that comes with a business.
It took me 3 years:
I just love the maker's mind.
Making things has never been so accessible, if you don't know how to start, join a community and ask, if they are hostile, just ask chatgpt and start from there.
3d printers are 200$, esp32 is the same cost as arduino nano.
Want to make AI things? Make them. Want to make coat hangers? Make them. Want to make a book stand? Make it.
I have few bank PCBs, and every day I hold one and I ask it 'what do you want to be?' and just wait and listen, it doesn't tell me, so I make it into what I want, and then try again the next day.
As David Lynch says, ideas are very quiet, you have to learn how to listen, so far I have not heard one, but maybe some day..
