Robot, micro-UAV, 3D printer - what kind of hardware startup to start from scratch and win?

Question

Iron

Hello!
Dear Toaster users, can you advise how to choose the right idea for a startup in the field of hardware?
I can’t program all day, I need to be distracted for 3-4 hours a day, otherwise I just start to “hang out”, at this time I would like to work on something that could grow into a serious project and business in the future. Nothing worthwhile comes to my mind. But, most importantly, having no experience in entrepreneurship, as well as not very much life experience, I understand that I cannot soberly assess which idea is worth taking on, and which one is better not to start.
Advise how to solve a problem that will affect my future life:
Given:
1. Enthusiast (at the junior level who knows PHP, HTML5, Lua, Photoshop, copywriting) = 1 pc.
2. Direct hands that can solder and assemble projects with Arduino = 2 pcs.
3. A room in an apartment with a solid table 1.20x0.80 m = 1 pc.
4. Free time, every day, without days off and holidays = 3-4 hours a day
5. Small monthly budget for components = $30-40 per month (the rest of the income is spent on living, because I am a junior and do not earn very much )
Task:
The maximum goal is to become the new Elon Musk or Richard Branson in 5-7 years.
The minimum goal is to build a business based on a startup so that you can only deal with it, because. it will be possible to pay monthly living expenses (food, utilities, housing, etc.) from the profit.
Decision:
_HERE_NEED_TO ADVISE_ I
imagine it this way:
1. The optimal project is selected (i.e., implemented as a prototype, but without machine tools, "on the knees", Arduino and parts cut with a jigsaw from 3 mm plywood in an apartment).
2. A working prototype is created.
3. A project is being created on boomstarter.ru for a prototype to search for investments for redesigning the project for mass production, launching production and fulfilling obligations to bakers.
4. Further development of the project, building an independently operating business, albeit a small and narrowly focused one, but not just a hobby, but a full-fledged system with a professional hired manager.
5. Repeat iteration for an already new startup, having more time and money for research and prototyping.
Thank you all very much!
Criticize, suggest, help. :-)

Answer 1

Study electric motors, invent transmissions for them. Get an electric bike.
or go the other way, collect the drone. Experience he and in Africa experience. All of a sudden, you start to cheat and hit engineering, and here you are so handy, you know how from firmware to a jigsaw.
I myself tinker with networks at work, and my hobby is to sculpt crap on arduino \ avr, paint and marafet ATX cases and understand the device and gadgets of various cars.
IMHO ofc
