micro electronics

Basic of this post is where e to buy micro size electronics for micro flying drones which are insect size? I asked arduino and raspberry pi, no answer yet.  in this post : https://www.instructables.com/id/3D-Printed-Ornithopter-Micro-UAV-Drone/     there is electromotor which OP claim that was used also by inventor of little flying drone...regarding arduino uno board i am not sure that was really used by inventor, please see pictures and videos on youtube....so if someone knows please post where to buy such micro size electronics.
Thank you

How small are you trying to go for the drone? What does the design look like? What kind of power does the design require from a controller? (Processing power, gpio pins, etc) Just as a quick answer I'd recommend you looking at Mouser.com, they have a very good selection of whatever components you could want.

I have in library bunch of pictures/images for people to see but For some reason I cannot attach it.

So are you tying to make an autonomous or remote controlled drone of the same size as those?

yes.

That's quite an endeavor, how far have you thought this out? Power source, flight method (wings, props, etc), accelerometer input, etc. I don't mean to rain on your parade, if this is really something you want to do then by all means pursue it, but this may be out of the scope of possible. I mean, no one has been able to do it yet, even MIT has only been able to make them with external control and power. However, if you want to make a small drone, I would suggest the surface mount Attiny85.

I noticed some typing errors in my previous post but I could not go back to edit my post ..sorry about it.

If you want tiny SMD lectronics it si no problem to oreder them as a private person, but the problem is the amount.
Just a simple 100kOhm resistor comes on a roll of 500 in the smallest possible order.
Transistors usually only on rolls of 1000 and more.
That is the only reason why you only see so few people doing it.
Unless you are willing to pay top $ from places like RS components for small numbers you can only order in bulk.

While I was doing my SMD projects I was working in a company producing laser sensors - I simply took the rubbish at the end of the week that the broom collected on the floor.
I do understand your frustration and that you feel left alone but unless you find access to a company in constant need of SMD parts you will be forced to pay high prices or get nothing at all.

All issues that you mentioned exist . I do not know will I succeed or not but I will try, Harward, MIT have many testing to do , many open issues , much more money and resources then me...I am not computing with them. I am just trying..I am sure that I am not only one in attempt to make insect drone out of institutions. There are already micro sized walking drones available for public but not flying drones with flapping wings. No, you cannot discourage me by any means. I am asking people who knows much more electronics and are familiar with all kind electronic components to help with information...I know that micro sized electronic component exist just don't know where to buy them...I hope people will be more responsive to this subject and get answer.

If this is something you really want to do, then do it! I think it's a fantastic goal! It's gonna take some serious effort, planning, and persistence, but go for it.

Usually for these projects on a "hobby" level people tend to use Arduino barebones or just the processor with a custom circuit board that also holds all other components for the project.
To go really small it would mean you use the smalles SMD parts available and design your board accordingly - nothing for people without serious soldering skills and/or the right tools.
Quite often these boards are designed to be a perfect size fit for the battery in use, usually Li-Ion types.
And as a tip for small scale prototyping:
Get yourself a thin sheet of PTFE (Teflon), 3-5mm thickiness depending what you can get.
It is great stuff for mving connections as it is self lubricating and you can use a sharp knife and a drill to get the shapes you need.
For structural framin parts check the supplies for small but expensive helicopters and drones - there is a lot of carbon fibre addons that can be substituted.
All you need is a very fine saw blade, sharp knife, sand paper and super glue.
