Solo mining into a multisig is an interesting idea. I suppose you don’t need any special pool software to do this.. any solo pool will do. If you want to host this yourself, the easiest way is public-pool on Umbrel.

We have a pretty break neck release schedule, so there is always a “next generation” around the corner! Hopefully they are cheap enough to dive in whenever you’re ready.

Cheapest by far is to manufacture them yourself. Details at bitaxe.org

The Bitcrane is a Antminer controlboard replacement hack/tool. It has USB, but is not a higher-power device like a Bitaxe.

2024-09-13 15:38:17

- reply

This is the issue exactly. Even USB-C PD with the chip you mention can’t provide enough power at 5V. I’m working on this for larger multi-chip Bitaxe though.

2024-09-13 15:36:21

- reply

Standard USB-C PD does not provide enough current at 5V for the Bitaxe 😭 so it’s a little more involved change. But we’re working on integrating this into a future model!

@npub1vwf…lxtw and I did a teardown. It’s well built. ASICs are a bit dated, but noone really cares in home mining. The only thing I can’t figure out is how they made it so crazy cheap.

2024-09-13 15:25:35

- reply

They were talking about the Canaan Avalon Nano3. It’s not really $99; they charge extra for the PSU. And AFAIK those cheap units are back ordered.
Solid machine though!

This shouldn’t be happening. (It doesn’t on my end). I’d like to figure out what it is about your setup that is causing this. Are you on the OSMU Discord?

No that’s not normal! Do you have multiple bitaxe stopping at the same time?

2024-07-03 23:08:44

You need to setup a VPN to home network to access the bitaxe remotely..

That does not sound good! Initially I’d say you have a bad power supply, but you said you replaced it. Please speak with the seller about a replacement.

The big mega miners can’t move though.. they’re publicly traded, govt-regulated companies. Their shareholders will require them to comply.

2024-03-27 03:22:13

Sigh, same here. I think a lot of miners didn’t fully realize what it takes to run these machines, and so they think they need a pool with lower variance.. another decision they’re not fully thinking through. 🤷‍♂️

"I would personally love to see a well documented Bitcoin-specific ASIC that is sold by reel (or in smaller quantities to hobbyists by a retailer). This way there could be many companies developing and offering products from "coffee-warmers" to 4U Terahash-class racks."
