These are ancient asic technology by today's standards and woefully inefficient. They'll cost you 10x more to run than they mine. Salvage the cubieboards, power supplies and cables and toss the rest.
Thanks -ck.
I actually want to get them mining again if possible. I know they are high watt devices for low hashing power (approximately 1GH/s per watt) by today's standards, but aside from my S7, they are what I have. My budget is these or nothing. I'm currently on an electricity plan with my energy provider, so electricity prices are not an issue at the moment. I would like to use some of them alongside the S7 for an extra boost in my hash rates. They also make great room heaters in winter...
