I ordered a coupe of these to work on as a Christmas project with my two sons. I ordered it on Dec 11, thinking 14 days was enough time for it to arrive. Not only did it not arrive in time for Christmas, it didn't arrive before my kids winter break was over, and as a result we never got to work on it. It was completely inappropriate for Tindie to feature this in a promotional email sent out during the US holidays.
Regarding the item itself, it's a very simple PCB with some self-flashing LEDs. I've soldered it up myself (kids are no longer interested), but since there are no instructions, I have no idea what kind of batteries it takes. I guess I'll have to see if I can figure that out on my own.
