Would really like to see things going the other way with less expensive lower hash lower power miners. Something more powerful then the 4TH Avalon Nano 3 but smaller then these 'mega miners'. Something you can run at home that really would work as a space heater but not needing so much power & cooling that your electric bill goes nuts from the power requirements and your ears bleed from the noise.
But this is still cool so.....

Yeah. the best that I have seen in 400-1000 watt 120 volt are the Loki spoofed s19 models I built 3 with parts from altairtech
I will be trying to build a t21 one board this week. waiting on parts. finding the right psu was hard.
I found a 1500 watt 13.8 volt psu which allows settings in the 12.4 to 15.2 range.
I would set it to 14.2 volts and see if I can get this build done this week.
