Repurpose USB block eruptors?

Hello All,

New to the forums.

I was wondering if anyone could give me any ideas regarding my old USB ASIC miners. I have about 12 of the 333 GH/s block eruptors and obviously there isn't much in the way of bitcoin you can make on them except for hobby or fun.

Selling them is pointless and other than them continuing to run on a USB hub with rasp-pi i feel like they are just fun to look at now for my kids.

Is there any other use for them? another crypto-currency perhaps?

Thanks in advance!
