Screen arrived today. Will hopefully have time to play a bit.

Oh, just noticed that's an esp32 board. So more like any MicroPython-compatible cpu/board that has the right display driver support?

Is it safe to assume that just about any RP2040 board with a few gpios should be compatible?

Raspis just aren't long-term reliable. My Raspi4 node died twice and completely corrupted its ssd each time. They would almost certainly do better with a UPS, but at that point the arguments in favor of repurposing an old laptop get stronger (laptop's battery is effectively a UPS).

And sure, "use what you have" but you said above that you ordered a new Pi 5.

Just trying to make the point that there's better bang for the buck (esp if it's free if you have an old laptop lying around!) and better reliability and performance out there.

Like I said above, the pleb culture has ingrained "node" = "Raspi". Trying to encourage people to seek out better (and often cheaper) options.

Help me out here nostr:npub1pfezegswrn8lpt0aerp2hvyhj4lsuzln9kcccs5p7qch2m2sawxsxcelvf!

I think you're misunderstanding what nostr:npub1r7psmkr4zv93xnal8un6d8hvmpsn5jvhfzn3kk38rfcel6awznks7znspg is arguing for.

When he says "hunt for used equipment" he just means an old laptop or a miniPC.

Most plebs mistakenly think "bitcoin node" = Raspberry Pi.

But the point is that even an older used computer is still way more powerful and WAY more reliable than a Raspi. It's a much better starting point for spinning up your own node.

So Dimi is saying: "Yeah, I sell refurbished used computers that are set up to be awesome bitcoin nodes OR you can absolutely do all that yourself."

Just don't do it on a Raspberry Pi!

Ah, there ya go.

Just need a vpn for SideShift (all these similar names are impossible for me to keep straight) if you're in the US.

I don't have any interest to venture out of Liquid and into shitcoin land, but I suppose that swapping to Tether on another chain in order to get it spendable isn't a crazy use case.

That I have no clue. This is the first time I've ever held any Tether at all.

If you want to interact with non-Liquid Tether tools/apps/sites, you're probably screwed. Liquid support on both sides (sender and receiver) is a prerequisite for using it (unless there's an atomic Tether-for-Tether swap out there to cross chains).

Yeah, I'd be scared to try to park any real value in USDT. Partially because Tether can rug you/lock you out at any time and partially because of the tax evasion-y-ness of these unreported txs. Just all the wrong sorts of trouble for a US citizen.

I tested btc to L-USDT: Peg-in onchain btc into SideSwap to receive L-BTC (you pay standard btc miner fee + 0.1% on the swap).

Then you can instantly swap L-BTC to L-USDT.

Liquid blocks are guaranteed every minute and they consider two confirmations (so 2 minutes) as finality.

Doing everything in reverse should work, too:

* swap L-USDT to L-BTC

* peg-out back to btc

* OR use Boltz to go straight from L-BTC to your LN wallet (pretty f'n mind-blowing!).

This feels so weird to have non-kyc, permissionless(ish?) access to Tether.

SideSwap instantly converted my Liquid btc to Liquid Tether with a ~1% spread (effectively a fee).

Nothing being reported to the IRS. Dunno if SideSwap has a limit on how much you can convert.

Regulators will eventually get around to locking US users out of this.

This shirt just happened to be at the top of one of my many t-shirt piles. Got it at some point at a conference.

Seemed apropos since I've been digging back into Liquid for the first time since my first go-round 2+yrs ago.

That being said, what I really need is a nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n t-shirt...

I was pushing it into a card reader and it must have gotten torqued against the slot, though I didn't think I was shoving it all that hard nor at a bad angle. I think it was mostly just a manufacturing defect.

Ought to be "SHOOT HERE" target practice for max security, no?!

Whelp, I guess there's a first time for everything.

With all the microSD cards I've manipulated over the years (and esp the last 2.5yrs working on nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl), I've never snapped one in half.

Super-clumsy moment or bad card? Dunno

Yeah, when I was reading about FPPS in general, there was just a vague explanation that the transaction fee share is estimated over some time period.

Dunno if Braiins has published any info about how they estimate and share the fees (their link in the dashboard UI is a 404 right now).

Braiins Pool is now FPPS (guaranteed regular payouts).

I had only mined in their previous PPLNS* system.

Braiins could go days without finding a block, so FPPS feels like an improved experience.

Statistically it shouldn't(?) make a difference which payout system you're in (assuming no pool shenanigans), but the guaranteed ongoing payout is psychologically more comforting.

I didn't realize that hashing credit would accrue every 5 min(?) or so. That's nice. If you popped in and hashed for 20 minutes and then shut down, you'd still get paid out for that span of work (unlike PPLNS where you could easily yield nothing, depending on luck).

---

*(PPLNS: paid only when they find a block, highly variable, and your hash participation credit dwindles quickly if you stop hashing--i.e. you get nothing if you mined for a while but dropped out before the pool found the next block)

Woot! Collagen chew stick so good!

Good question. A fixed voltage/freq probably isn't ideal here (I hadn't thought through that for this setup).

I'm relying on Braiins OS autotuning to step in and reduce hashrate if the chip temps start getting too hot. That could happen if my house's ambient temp gets too warm or if I dial back the external fan.

I've done the same with S9s w/external fans. I set a higher Braiins OS wattage target, but run a quieter, weaker fan in front of it. Braiins eeks out what hashrate it can, but modulates to stay under the target chip temps.

Have to manage it on that side since the control board has no control over the external fan.

The 4 case fans (2 front, 2 back) have been removed. The 6" inline fan is doing all the work. It has a manual speed dial which I have been tweaking while Braiins OS autotunes. Trying to keep the chip temps below 75°C.

A little disappointing, but basically having to run the fan at full power to keep up, so a little noisier than I'd like (~59dB @ 1m). But still way better than the high-pitched case fans.

The S9 power supply (APW3++) has its own small fan, but it doesn't contribute anything audible when the 6" is pushing this hard.
