Welcome back on the forum OP!

Very interesting project.

Yeah, personally I'd be interested in supporting your project and would happily buy a few units from you, I love letting little ASICs like those (usually from Gekkoscience run solo).

I'd even like to be a reseller in Europe for you if you're interested, if after I've been able to test them everything's OK, I'd be sincerely interested.

I'm currently in the process of learning how to make Bitaxe myself, a DIY sha256 ASIC based on BM1397 created by Skot (who replied to you above) that reminds me a lot of what you're describing. Feel free to check out this Github if you're interested: https://github.com/skot/bitaxe

Don't hesitate to contact me privately if you'd like to chat, and I wish you all the best!
