Re: 28nm ** 1T ** 900W【JingTian miner】 in production !!!

Got it. It's a monstrosity with 3 external power supplies that I have to wire in myself... however even the power side needs to be screwed in with bare wires, and that's basically illegal to do in my country unless you're a certified A grade electrician... so I'm not sure exactly what to do with it yet Undecided

External power supplies?? Got a picture?

It's as per the opening post, but with one extra power supply (presumably a spare/redundancy). Here's some photos, including a baseball cap for size comparison:

Uggh.. wouldn't be an issue for me to wire it up here in the UK but I thought it was gonna look more like the Dragon miners (massive black box with two ATX PSUs) like bobsag got.

Sure it's easy to wire up. But it's also illegal to do mains wiring yourself here. PSUs would have been much simpler, but in fact these are much higher quality and more expensive than regular PSUs.

yes, I know our company has arrange someone to pick it up, wire it up ,and send it back to CK.

Also , i like to point out. JT miner spend lot's of effort in the firmware and Pi side. they use the ST MCU. the firmware is written from 0. after JTminer use the ST MCU. some vendors' solution seems to have interests in ST MCU too:)

The Pi board can drive up to 8 boards (in lab we do), and each MCU to control the two SPI high speed chain. in this way, give the whole system more flexibility and scalability. it's not a small job can be done in a very short time, actually they spend one month in hardware and software with 3 high profile engineers.

so please show some respect, JTminer are the firmware author and some Pi's controller code talking to the ASIC boards
