I am curious is the media blitz over a bitaxe finding a block has resulted in a tidal wave of new orders or not. I’d imagine that’s better advertising than could be bought and there’s a lot of folks dreaming of their own Bitcoin lottery win today. Anyone in the know care to share if this news did result in a tick up in sales?
From what sellers tell me, the uptick in sales has been significant
July 25, 2024, 01:31:36 AM
Maybe not. At least in my opinion, this equipment remains a bit expensive if purchased ready to use.
Yeah most of the time, a ready to use bitaxe is sold ~$150-$200 online.
Still cheaper than Gekkoscience ASICs, but indeed quite expensive.
I hope that the lucky miner can have the pride to have assembled the bitaxe that found his block himself

may take a week to know this. Maybe they will let us know.
200k plus is a nice hit. for the winner.

First (known) block found with a bitaxe guys! 
Congratulations to miner bc1qk4czgwtfhxwfd9r696kzledtmlu8yukdzpzn3u with the first bitaxe and only a tiny 3.1TH for finding the 290th solo block!
This much hashrate only would find a block once every 3500 YEARS on average, or one in 1 million per day!

Hello, I have a question, I have bitaxe ultra board 204 sw v2.1.8, I can't mine anything except btc, I tried new projects with low difficulties, bch, microvisionchain, ecash as well as other coins that use the sha256 algorithm with different set difficulties , I get many rejected shares or cannot connect to certain pools and I would like to know where I am wrong, what is missing from the equation, why does it only work on btc and not on other currencies with sha256 algo even if I set the same difficulty as btc?

I can confirm this will work with the LuckyMiner LV06 units as well but you must be patient and let the upgrade complete. If you try to leave the page while the units say working you very well may brick the units!
If you upgrade esp-miner on your lucky miner it will set the stratum user agent to Bitaxe and nobody will be able to tell you're running a shitty knockoff
The best part is they now put stickers on the LV06 warning you not to update the firmware! Yeah.. That leaves me with great trust!
lmao..feels good to have it "original"... god knows what pesky code they put in there

FWIW this bug only affected the best difficulty being stored to the non-volatile memory. Nothing to do with shares
yea amount of 32 bit buffer overrun bugs in our new UI was fun tracking down...
btw hope you guys have simulated a very high share in your firmware...early miner firmware was notorious for bugs like this but in the actual shares, so the miner would crash/submit an invalid share for an actual block find...
May 24, 2024, 01:08:07 PM
FWIW this bug only affected the best difficulty being stored to the non-volatile memory. Nothing to do with shares
The display didn't match up with the pool data on best share which is what I was referring to.
If you only look at the display for best share or the UI then you really wouldn't have accurate best share info.
I am glad to see this fixed!
we could use your good luck to test this fix out!
Fingers are crossed and all systems are a go!
BTW... The "LuckyMiner" LV06 which is a complete rip off of the Bitaxe Ultra can also make use of the newest firmware version.
https://github.com/skot/ESP-Miner/releases/tag/v2.1.4
I found that the OTA update works fine.
Just make good and sure that you do the esp-miner.bin first. Wait at least 20 seconds after the "working" disappears. Restart and then do the www.bin and also wait for 20 seconds and then restart again and you should be up to date.
DO NOT RESTART WHILE YOU SEE WORKING ON THE SCREEN OR 100% YOU WILL BRICK THE LUCKYMINERS...

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).

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.

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?)

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!

We should be careful when we buy our Bitaxe, there are already scam websites.
For example, here's a message from the OSMU Discord aboutbitaxe[dot]de, which we should all avoid. You can find legitimate resellers here: https://bitaxe.org/legit.html

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.

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

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

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.

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.

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.
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.
Mostly happens when this Air Force plane flies above me.
https://en.wikipedia.org/wiki/Boeing_E-3_Sentry
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.

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.
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.
Mostly happens when this Air Force plane flies above me.
https://en.wikipedia.org/wiki/Boeing_E-3_Sentry
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.

-The BM1366 has a different footprint and pinout from the BM1397 and BM1387 in previous bitaxe.
-The BM1366 appears to roll more than just the nonce on the chip. This is great news, because it allows much longer serial chains of ASICs and new work doesn't need to be sent as often.

At the moment I have no problem with the 2.07 firmware.
Reverting back is possible with the normal website from the miner? Or do you flash the miner per USB?
Just interested to be prepared if I have also step back to a older firmware.
Best regards,
Willi

Yes you can revert back from miners UI / Website.
For me V2.0.4 seems to be more stable.
You guys make sure to report an issue here:
https://github.com/skot/ESP-Miner/issues
It's much more likely for the maintainers of the firmware to see it there.
Do include as many details as you can (e.g. after how much time exactly something happens, what happens, ...) to help them get it fixed.

Got the same issues that Sledge is reporting.
Cannot address the exact problem but getting reboots in the same time frame or the hashrate is decreasing to 0TH/s and is stuck until I do a manual reboot.
Will flash back to an older version and will monitor it.

Hi
Has anyone tried using a voltage value of 1300mv for a few months? could it be exaggerated or dangerous for a long time? Thank you
I don't own the BitaxeUltra, but having worked with similar chips on stick and pod miners in the past, it's generally safe to run any voltage, as long as the chips stay cool enough.Has anyone tried using a voltage value of 1300mv for a few months? could it be exaggerated or dangerous for a long time? Thank you
In some cases, industrial miners run their chips at substantially higher voltages than the ranges we use on micro-miners, even when using the exact same chips, simply because they have better cooling solutions like high-flow, high-pressure - but very loud - industrial fans, or liquid cooling setups.
Do keep in mind that there's a point where your efficiency starts to decrease, simply because the increased power draw from the higher voltage stops yielding substantial improvements in stable clock speed (and thus maximum hashpower), so keep an eye on that as well.

feedback: please make a ethernet vesion. Due to privacy and security issues, i dont use wifi. Hope the bitaxe HEX makes it or atleast has a USB Type C so one can use a ethernet to type C adapter.
The ESP32-S3 we use in the bitaxe does not have a Ethernet MAC, so this is not an easy change. What sort of privacy and security issues do you have with WiFi?
Great project, inline with the Bitcoin spirit! Skot, did you try to use a PWM pin connected to an RC filter, can even be two stages of RC filtering, to get rid of the DAC IC? Let me know if I can help.

I can understand that, and I am thinking the same way.
There is a development kit for the esp with phy but you have still the firmware and tcp stack from the vendor, with all the "goodies".
Anyway, there is a fork of the bitaxeultra named Pi-axe.
I pointed that allready out here in the german section:
https://bitcointalksearch.org/topic/m.63279811
The design is as a "hat" for the Raspberry-Pi and you use the Pi Network, LAN or WiFi for comunication and it runs under a normal Linux.
The User Mampf of the electronic forum mikrocontroller.net has made this as a hat for the Raspberry-Pi and provided the files for it in github:
Pi-axe Hardware:
https://github.com/shufps/piaxe
Miner software in python for the Raspberry-Pi:

You’ll need Linux and host mode USB for that to work — both a long shot for the ESP32. I think there is another ESP32 variant that has an Ethernet MAC, so that would be an easier place to start. There is a company called Olimex that make some ESP32 Ethernet dev boards (PoE too, I think). That would be a reasonable place to start.
PoE+ miners would be insane! :~)

Has anyone pointed out the equipment required to attach a BM chip to the board?
Yeap,
Buying equipment, if you don't already have it, would be expensive for a single Bitaxe, but that depends on who it's for. If you see building it as a hobby, the cost shouldn't bother you too much either
Anyone got any idea how much that is?

If you only want to use one Bitaxe, it's a good deal.
If you want more than one, and you have the desire (motivation + skills ) and the time to build them yourself, it would probably be much more cost-effective to buy the tools needed to assemble your own ones than buying them like the link you shared.

Depends on ur skills. If you got some free time you can invest it in building it on ur own. Way more fun and you would save more than 100$.
In addition to saving money, you get so much more into the matter and keep yourself busy automatically.
But as mentioned before, you have to see for yourself whether you have the time + desire to do so. Otherwise, the offer is of course an alternative, but of course you pay.

Let's get this party started!
I'am in!
Got the KiCad drawings downloaded and I will Post changes also open source (or send it to you, as I got no Github account).
My time is limited until end of september, but then I can produce a batch of boards.
I mean fully assembled SMT and THT. So I can start to do some work with Hard and Software.

it would also be cool if Skot would team up with crypto cloaks to make a nice case for their ultras, which would also be available in different colors.
cc has already printed/manufactured the matching boxes for some hardware in the past.
what about the cooling - how hot do the chips get? as i can see on the picture, a noctua nf-a4x10 would be enough, right?

Can help you out with some 3d designing for ur bitaxe if needed.
It doesn't necessarily have to be a business and might be easier. Atleast for the individual and personal design. If you are satisfied with their prints you are good to go!
There are already a few simple solutions for cases if you look around on

Yes, it’s very possible! There are a couple designs in the works that I know about with both BM1397 and BM1366. The BM1366 is especially well suited to chaining multiple chips together.
The ASIC is the hardest part to solder, by far. I suspect once we get into multi chip boards, soldering beginners will be left behind.

As long as both versions exist, I think it could be of interest to everyone. Those (like me) who are new to chip soldering will always have the basic version to get the hang of it and build their experience.
Having an open source multi-chips board would be great, and I actively support this idea!

But still curious if its possible to use boards with the possibility of using more chips.

Hi seek3r!
Thanks for your support! It’s a daunting project for sure. Have you heard of d-central? They are a miner repair shop in Canada that has been a big supporter of the bitaxe. They are selling partially assembled kits that sound like what you are looking for. https://d-central.tech/product/bitaxe-diy-kit/
Currently d-central just has the BM1397-based bitaxe, but that is a great place to get started, IMO. I haven’t ordered from d-central myself, but I know of several people who have, and no complaints!
Thank you for ur reply. Yeah. I watched the 3 hour livestream video on YT when they assemblied the v2.2 a few days ago!
Would wait for Kit with the BM1366 chip instead of buying one of the S17 chip.
But still curious if its possible to use boards with the possibility of using more chips.

Thank you for your efforts, skot!
I've been following your project for a while.
I have thought several times about building my own miner with the help of your detailed instructions. Unfortunately I haven't had the courage so far.
Wondering if it would be possible to get a few chips attached to a single board? Would this be a thing for the future?
I know that there are some Gekkos out like the R909 but your project comes with a lot of benefits like:
- Open-source
- Standalone Miner
- way more efficient

- how much hashrate you've manage to get out of bm1366?
Initial tests are sitting just under 500 GH/s and 22 J/TH. plenty of optimization left to do.

- I think you should somehow arrange your tree branch in github someway. maybe sort them by chip kind. its a bit confusing by their names IMO. hex, ultra and some number based branches...
I agree.. things have been moving a little fast for organizing just yet, but it does need to happen sooner or later

- did you see gekko compac f? it's using much less components as far as I know, like doesn't include any microcontroller or esp for mining and solely depends on usb, right? any thought on doing something like that?
yes, definitely. GekkoScience is cool stuff! I'm probably not going the usb stick miner route myself, but all the design files are out there, so you could easily adapt it if you'd like.

AFAIK there are no datasheets for these parts.
August 22, 2023, 03:41:11 AM
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.

First, Thank you for all your efforts.
Did you find any datasheet on 1397/1398 yet?

Let me start with 
I'm watching this for sure! I've got a few remarks after looking at the schematics. I presume you've got the bm1366's connections from tracing the signals on a hash board and not from an 'official' repair guide? There are a few things that stand out to me and might be worth looking in to;
- the mode_0(in) and mode_1 signals are connected together.
&&
- the decoupling caps c4 & c16 are connected to to these pins
To me it seems as both pins are actually ground (vss). You can check for connection of these pins with the big ground pad to see if that is correct.
- the mode_0 pin is left floating for mode0
Antminer has previously defined mode0 as mode_0 pin connected to ground.
Changing the description of these pins and of the mode does not change the functionality of anything but seems more correct to me (if the 2 connected pins are actually vss).
Did you find a way to log the communication with the hash boards or are you going the software disassembly route first?

Thank you Skot for proposing great projects like this one! We need more open source ASIC projects!
I hope you'll be able to produce something as cool and clean with bitaxeUltra as you did with Bitaxe!
I wish to you and this project a great success! As always, don't hesitate to let me know if you need funds or components, I'd be happy to contribute to the project!
