That was well done, Gerald! I think I may have that same keychain camera, lol. I paid less than $7 for it (including shipping) and I mount it on my planes, as well. I can never remember how to change the time stamp, lol. Great flight video!!!
Into the ROOT of the camera file system. When you plug it into the computer, you will get a popup. Open the file and put the file in there. If you put it in the section with teh videos, it will not work. Once in there, remove it from your computer, shut it off then turn it back on. When you turn it on, it will see the file and set what you have input into it.
Funny thing is I did read the instruction paper that came with it and I did put the current date in it or so I thought!
Will attempt it again at some point.
