I was one of the unlucky few to be scammed by KNC back in the day, buying into the Titan miners and never getting one until it was pointless to mine as I would never see my ROI, even though they were (I want to say) nice enough to send me a second batch of Titan miners that I never took out of the box. And they weren't so nice shipping the second free batch as it forced me to pay the duty on something I was getting for free, which was a lot of $$. (sigh)

When I finally did open the second box and attempted to power up the Titan cubes, the controller board was bad, no reset or FW update could fix it. And not all the miners worked.

Fast forwarding to now and I wonder if anyone attempted to build a new controller board that allows you to connect two batches of miners on it? I know a lot of people who use PCBWays to build their boards after they design them are doing a lot of retro projects.

As far as the minners not working it could be the caps they used aren't good quality ones. My first batch of Titan's are having similar issues now as the second has, were they don't start up. But I have some ideas for them as a project when my son is older.

Thanks,
