Seriously! They work great. I have reflowed a lot of prototype PCBs over the years in a $50 toaster oven... The only reason to upgrade to a fancier reflow oven is so you don't have to sit there and manually adjust the temperature.

there is a small update from Skot and his project. yesterday he sent the following tweet in which he tells us that the development of the bitaxeUltra miner is as good as finished. the orders should be placed in about 2 weeks.

at the same time they are also working on a 'multi' solution. this is called bitaxeHex and as you can see on the following picture, up to 6 chips can be used.

Unfortunately, delivery only to the US 

That's one more reason to make some DIY bitaxes in Europe

i picked 2 of these up from opensourceminer.com at $125 each. the performance is extremely impressive and the set up was pretty brainless too. insane work.

Thank you for the link, just watching that right now.

Edit: Suprise, a bottle of champaign is stronger than a Bitmain miner LOL.
Ocean, aha, time will tell.

that was crazy the bottle beating apart that miner!

im curious about the esp32 im not a fan of unknown radios which is what kept me from messing around with the bitaxe stuff can you remove the radios with some snippers or are they in the main chip?

[cygan]

here is the first picture of a bitaxeHex compared to a bitaxeUltra - in my opinion, not much bigger than the 1-chip version
here you can see the difference in size very well and what you can also see are the 6 built-in asic chips
fingers crossed!

This looks epic! 6 chips!

Have you had it running yet? any temps hashrates?

Looking at getting a few of them myself the S3's really need to retire.

Waiting for the HEX version Pulling about 100w is enough for my electricity bill ^^

Great 
You'll see, they are very nice products!

But the screenshot you shared show a price which looks expensive to me. You can find them already assembled for 130-150 usd.

Yeah but these are in the US and come with a nifty little case!

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?

[willi9974]

I am very happy about the project. I already have two bitaxes running in our small solo mining pool project and there are more and more.

Can't wait until the bitaxeHex is available, I'll buy one or two if the price is right.

If anyone would like to support us, please feel free to join us on the hunt for a block.

We mine under a common address. Details in the two posts either in German or in English.

I dont like wifi due to health issues, You can atleast have a V2 or USB type C so that users can buy their own ethernet to usb type c adapter.

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.
