Once the design settles down a bit, we'll do an at cost group buy of assembled PCBs so people can start hacking on them. Stay tuned!

Finding a reliable (and affordable) supplier of BM1397AG for this is on the to-do list!

A mí también me interesa la compra de mineros. Si estáis interesados, tenéis alguno y queréis venderlo ponedlo por favor. Soy de Madrid https://descubremadrid.net/ así que si alguno es de aquí mejor que mejor.

thanks a bunch to all --- that was very helpful
will stay away from s17

I found an interesting project about creating your own ASIC using two BM1387 chips. The cool thing about it is that it's all open source: KiCad design files, BoM, software, etc. Basically an Open Hardware project.



Github with sources here: https://github.com/skot/bitaxe

Here's a reddit discussion about it: https://www.reddit.com/r/BitcoinMining/comments/uymwj3/experimental_bm1387_bitcoin_mining_machine

It's not finished yet, but it's something interesting to have a look if you're planning to make your own ASIC miner, or you want to help create an Open Source one.

Also, the person who created this is now looking to make it work with cgminer:


This would be great to tinker with, specially with cgminer.

Dear miners, It's taken a while to find some time to organize this with work and life duties but my goal was to share this. Hope you'll be able to find some use.

What is this? Functional 3D printable exhaust capturing both hash board and power supply end for S17 series. (possibly others, unconfirmed)  
What the hell? This mining community has really allowed me to develop my passion for mining over the years and in concert with that, I can in some form return this knowledge by leveraging my design and engineering skills for those running S17 series miners on air.
What miner was this design based off of? S17Pro 53TH
Project Timing: 1 month+
CAD program: NX
3D printed process/material: Duraform PA SLS glass filled Nylon with a heat deflection temperature (HDT) of 134C, also chosen for it's strength (baseplate and clips).
What other additive manufacturing processes and materials can I use? FDM: Carbon-reinforced Nylon, ASA (HDT) is 102C. SLS: 100% Nylon PA. SLA not recommended.  
Outlet size? 8" for unrestricted thermal flow and common duct sizing.  
Where can I see images of the process/prototypes? https://drive.google.com/drive/folders/13pxwNq3i_UbBT4-HtUTQX8JJ3rYCMvaU?usp=sharing
Applications of scale:  It's scalable from apartment mining to smaller mining operations where rack space isn't at a premium.
Will it fit S19's and T17 series? It was designed for an S17Pro so to confirm I'd recommend pulling dimensions from your machine chassis and fans to reference. Screw slots on the base plate allow for adjustment room only in the Z direction
File format: .stl (x2), BASE_PLATE.stl and SHROUD.stl
Where can I download the .stl's? https://drive.google.com/drive/folders/1w3BvUKmdP96TeiACywiTfjAslpd6fWGN?usp=sharing
Installation tips? The miners fan through screws don't need a lot of torque, just a soft tightening. SLS PA is one of the most robust materials to work with so cracking and shearing of the base plate from over-torquing wasn't an issue. Be careful to slide the shroud in and out parallel on-axis with the base plate clips for reasons of shearing those off. If something does break on the base plate for some reason use 2 part Plexus MA310. Or just reprint it  

If you have any questions about 3D printing processes or materials please feel free to leave a question. Any other questions or issues I will do my best to answer.

Whether big or small, if you at all find these parts useful or helpful, I will not say no to tips via the address in my profile. Hopefully, this can be put to good use and it would be cool to see this working for other miners, as it does for mine.

Best,
