Mine are "too hot to touch to get out of the usb slot" only a few
moments after plugging in and rngd starting to do it's thing.
The PCB itself gets hot btw, not just the metal shielding.

They cool down amazingly well when taken out of the port.

They do produce 2400+ of entropy even after whitewashing (the openssl
trick the package does).

I'll wait for the second call as mentioned at:
 https://www.kickstarter.com/projects/moonbaseotago/onerng-an-open-source-entropy-generator/posts/1299117
likely there will be more details then and maybe a "if you do this
they'll stay cool" thingy.


Btw, is there a git repo somewhere for the Debian package & software,
there are quite a few improvements to be made (not depending on 'at' for
instance, and not mailing the output of that whenever it gets plugged in...)

Greets,
 Jeroen
