I have no knowledge of boards before,there are some capsule toys that can play sound,several of them can only play sound in about 10 seconds,suddenly I saw someone try to change parts in them to let them play a whole song,but they didn't put the whole thing in the toy,I want to try it too but I want put all the thing in it,problem is space is small,something like 22 * 22 * 14mm,or41 * 31 * 12mm,I can consider using other things for the shell,but if it is too big then there is no meaning doing this,things were fine till I found my cell batteries couldn't power it,so what is other option here?
I saw someone using attiny 85's chip to control it too,but I can't connect a micro usb board of this to win 10,nothing change on the pc,but the board can flash,what is the problem?
Also the pins take too much space,I want to take them out but is it safe to do so?
"Capsule Toys" are not always electronic devices (link here).
Which toy do you have? (upload picture)
Does your toy have an interface/connector?
Where did you see someone change parts, or use tiny85, and did they show a working result?
The important point is capsule is small,can't store something big,the space is more or less as above.the toy is piano mascot,there is somebody using a kit for playing other sond that doesn't put the whole kit in the piano.

It is possible by using lithium cell which size is 20 * 25 * 4 mm,but I don't know how charging work,when it goes out I will connect it to a board for charging and see whether it works.
Still can't do much since don't know how to use those chips yet.
It is the same kind of battery as a no display mp3 I bought,but mp3 plays all the songs,or I will just put a mp3 in a shell and connect buttons only,it is also very small,so I believe it must be possible to do so,problem is how hard it is.
I use the micro-usb charger from a "broken" rechargeable LED torch/flashlight for a 602040 (60x20x40).
Anyway there is the result,only using default control next,if all pins are taken out there is more space,but it is hard since it is small,it can hardly fit this way.
