Puck rebooting in RF isolation environment

Hi everyone, I have been using the Puck for a while now as part of my research and I have run into some very, very weird behavior recently. I am trying to do some tests where I put the Puck in an RF isolation box (Ramsey) so I can isolate the signals coming from it and for some reason it just refuses to work.

If I load a program onto the Puck, it works completely fine until the second I close the lid on the RF box and then it appears to reboot continuously until I open the lid, then it happily goes back to running the program that was in flash memory.

I have attached a video showing this happen. I loaded a program that just blinks the green LED when the button is pressed. The red light is, I believe the Puck rebooting? It keeps doing that indefinitely if I keep it in the box.

Any ideas as to why this might be happening or what I could do to fix it?

Figured it out. The gloves were actually shorting out the Puck. They are extremely conductive I guess. When I put it in the housing it worked fine.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
