For a moment I thought that it is at worst* again one of those taxidermy cameras. Positively surprised. But the idea is quite old. Here is one building guide https://www.instructables.com/Mouse-Cam/ https://www.instructables.com/Mouse-Cam/ I couldn't find the date of the article but the comments are there 16 year old. And as far I can remember, this is not the original. So can be 1-5 years older perhaps. * I also thought that perhaps they are now able to read what mice sees using some MRI or neural link technology. In that sense I'm disappointed a little.
