The bitaxeUltra: Open source Bitcoin miner based on the BM1366 ASIC

[philipma1957]

Yeah but I am near an Air Force base which routinely knocks out my wifi for 20 or 30 minutes at a time.

I would want to run a few of these with an eth cable.

Like, knocked out from RF interference? That's wild.

It would be a big job to add ethernet to the Bitaxe. It's built for WiFi from the ground up. I wonder what would happen if you directly connected the ESP32 wifi to a wifi router with coax... Espressif makes a drop-in ESP32-S3 variant with a u.fl antenna connector. I assume some attenuation would be necessary.

. I was stunned the first time it happened.

Mostly happens when this Air Force plane flies above me.

I would think it is the radar that does it. I live about 15 miles from the base. It does training sweeps every now and then.  Really fucks wifi up whenever it doe the low flying tests.

This is interesting because I've never seen anyone else say this besides me, but I too have some experience having wi-fi knocked out from airplanes...  They do some F-35 testing near me and I am an avid drone flyer.  I used to use wi-fi for my drone flights because I liked the idea that I could setup a giant wi-fi mesh network in my area with large antennas and boosters (shhh, don't tell anyone).  My original idea I was testing was to have a set of drones taking turns 24/7 circling my area as a type of surveillance to be controlled by a computer running a program (the challenge is in the automated recharging process).  Whenever they would be testing F-35s in my area I would notice that I would completely lose connection with my drone until the plane had flown away.  It happened enough times that I actually abandoned my giant drone wi-fi network and switched to other technology.  Now I use radio signals and for long range flights I would IN THEORY use the cellular phone network.  I would bet quite a bit that next gen fighters are able to disrupt wi-fi signals either purposefully or via a biproduct of however they operate.

Yeah if they are running the large spiral pattern at say 2000-3000 ft the wifi dies and only a hard reboot will fix it.  worse yet never do a firmware update in my house via wifi I bricked 2 printers and a Mac mini all due to my buddy the us Air Force .  I was navy so it becomes more annoying that the Air Force is doing it to me.

I wanted to let everyone know about a new revision of the bitaxe miner being developed based on the Bitmain BM1366 ASIC from the Antminer S19XP. Like the previous bitaxe based on the BM1387 (S9) and the BM1397 (S17) this is fully open source hardware and firmware.

HW development GitHub repo: https://github.com/skot/bitaxe/tree/ultra

Let's get this party started!

Hi, do you have datasheet of BM1366?

I don't think such thing exists.

I learned about this project today, it seems very interesting! Congratulations on the project!

I remember in 2013/2014 here on the forum there were schemes to create ASIC miners. At the time I analyzed them, and I even thought about putting something together. But, I ended up not moving forward. More recently, I looked for these schemes again, but I couldn't find them. I still know about this project to this day.

That being said, I would like to ask the following:
- What is the link to the technical drawing? ^{I would like to print it and show it to my father, he is the one who knows how to analyze these drawings.}
- Can I find all the components I need to buy here? - https://github.com/skot/bitaxe?tab=readme-ov-file#hardware

Happy to see you here my friend.

For your questions:

-From the drawings, do you search this link or something else? : https://github.com/skot/bitaxe/blob/ultra/bitaxe%20schematic.pdf ?

-Yeap for components, + the PCB https://github.com/skot/bitaxe/blob/master/assembly.md  
and some tools of course (tips : https://github.com/skot/bitaxe/blob/master/assembly.md)

If you want you can join our Discord community, it is very active and people are always happy to give more specific infos: https://discord.gg/sfHm9GRV

Thanks! It will be useful.
My father having the schematics and the parts should be enough to put everything together.

Are the components easy to buy?

The programming part will only be more complicated, which is something I've never done.

I'll try to visit this group on Discord.

I hope that you will have some time to learn from your dad skills, this is so satisfying to build your own asic!

Yeah the components are (more or less) easy to buy. Chips can be complicated because of minimum of order for quantities etc... On the discord group, we have someone selling chips frequently (in case you have difficulties to order via chinese websites).

You'll see, the programming part is not complicated, pretty straight forward

I have no problem buying from Chinese websites, as long as I know which components to buy.

Is there any step-by-step tutorial?

I am currently working on a text tutorial on building Bitaxes. I will need more months btw

There is D-Central who did some very nice videos on Youtube:  FRIDAY WARRIOR Special Livestream - Learn how to make Bitaxe v2.2 Open-Source ASIC Miner - 063

Another one:  Live Assembly and talk about the Bitaxe

Without a doubt, this is not an easy task, and it takes a lot of time.
It will be good to see your tutorial.

Thank you for the tips.

All of the PCB components (except the ASIC) can be bought from DigiKey. I have “DK” part numbers in the BOM. You can get the ASIC in single quantities from Chinese sellers on AliExpress. PCBs are cheapest from China. Links for these things are in the readme.

[paid2]

We should be careful when we buy our Bitaxe, there are already scam websites.

For example, here's a message from the OSMU Discord about bitaxe[dot]de, which we should all avoid. You can find legitimate resellers here: https://bitaxe.org/legit.html

So I did find some interesting things out today as I got to tinker a bit more.

ASUS ROUTERS:
Do not try to assign a "manually assigned ip" on a Asus Wireless Router to a BitAxe. For whatever reason the units seem to crash out sporadically and don't reconnect correctly. Remove the manually assigned IP from wihtin the router UI and all is good. It is recorded as de-authed device in the Asus router log when the units try to continually reconnect. So do yourself a favor and let DHCP handle the IP addressing which should help keep things more stable.

This seems to happen with both v201 & v204 pcb boards and the "Lucky Miner LV06" which is a complete and total rip off of the BitAxe. (I did share a breakdown of the hardware of the Lucky Miner LV06 with Skot)

Now... I bricked a Lucky Miner LV06 so please read this if you have one and try to update the firmware.

The Lucky Miner LV06 can in fact run and use the esp-miner.bin V2.0.7 firmware file from here: https://github.com/skot/ESP-Miner/releases but if you try to update the www.bin from https://github.com/skot/ESP-Miner/releases it bricks the miner and the UI is inaccessible.... So update the esp-miner.bin but DO NOT UPDATE the www.bin file on the Lucky Miner LV06!

Enjoy!

Love the Bitaxe so far.

Been playing about with interface designs and possible updates for additional information in the dashboard.

1. Possible to add a realtime bestshare value I noticed it shows the overall bestshare this is good to know but if I restart the miner it would be good to see a rolling best share from restart below the overall best.

2. Further peak and min voltage values on the dash would be nice.

3. Debug mode (show more information in the log window when debug mode is active (possible?)

I've got two Bitaxe 201 boards. One of them is happily hashing away after applying esp-miner-factory-205-v2.1.3.bin directly to it over USB.

I was unable to connect via USB to the other one, so I updated the firmware to 2.1.3 (successfully) via the web interface. However, when I tried to update www.bin, it hung for about 10 minutes. After power cycling it, there's no display and I still cannot see it via USB.

Any ideas on how to get this working again?

Thanks!

It's not a good idea to apply the v205 factory firmware to a v201. I'm glad to hear it's still working though!

As for your other unit; Did USB ever work? Make sure you are powering the Bitaxe with the 5V main power and not just USB. If that doesn't work it sounds like faulty hardware.

[thak777]

Oops. Didn't realize I was doing bad things by applying the 205 to the 201. Should I flash it back to a 201 of some flavor?

I've never had USB working on this second device. I was able to see the device on it's provided wifi at first, but it could never connect to my wifi (so it could never connect to the internet).
