Very badly outdated by now.
thanks good to know. is there a current version that's similar?
sidehack is making usbsticks using more recent chips... However, if you calculate the hashrate vs the power usage plus the extra costs for a controller and a powered usb hub, i don't think they can compete with an S7-S9 (didn't bother to do the math)...
Sidehack does a great job, but AFAIK, his sticks are best for hobby miners, education or playing blockchain lotto.
