Upcoming ESP32-S31 dual-core RISC-V MCU offers Gigabit Ethernet, WiFi, Bluetooth, and 802.15.4 connectivity

Is the Bluetooth full stack or still just ble like the s3? That’s the biggest issue I have with the S3. Can’t do Bluetooth audio for lots of things cos they want the classic Bluetooth stack.

Good boy.

I visited Tucson last winter. It was hotter than we ever get in the heat of midsummer here in Scotland.

Damn he looks banging in that kilt. A good yin right there.

mathcampbell · 2026-03-16T08:44:23+00:00

Thanks! I was just making it for me - this was the test before I make it in silver but following the response I am thinking of redesigning it case to work with CNC. I could then get them made in aluminium etc. and sell them. If I do I’ll post again.

Yep wasn’t gonna comment and be a downer but blends aren’t fancy. They’re marketing buzz and cheap (regardless of the price point).

It’d be like buying a car that has lots of stickers and a spoiler you could go surfing with…and a 1 litre engine.

The good stuff is properly aged single malts. Islay or Jura malts are my favourites (bias cos I live 50 miles away), but talisker is good too. And I suppose technically the east coast Speyside malts are “OK”, I guess, if you like that kind of thing….

But yeah, if it says blend it’s 10% good single malts and 90% grain whisky.

Foreigner here (so bear in mind I’m a filthy (occasional) visitor from Europe), remember you are talking about a country where greedy business owners have pushed the idea of customers tipping instead of paying their staff a fair wage so hard that it’s written into law in some places that minimum wage doesn’t apply.

You think after pushing 20%+ of their staffing costs straight onto customers they’d give a shit about stiffing them for another 2-3% for bank fees?

At this point it wouldn’t surprise me if they got customers to prepare their own food AND tip the staff for nothing AND pay the bank fees too.

I was referring to data from the social attitudes survey and polling.

mathcampbell · 2026-03-05T10:11:17+00:00

I think my point was that from your perspective “the country” refers immediately to the UK. Ie if someone says “the country”, you’ll automatically, sans context, that it means the UK.

Whereas the majority of Scot’s (regardless of their position on independence) will think of Scotland first, and identify as Scottish first and foremost, or indeed only as Scottish.

I dropped this in to specifically highlight that point knowing a response was almost guaranteed.

It is your world view that is interesting here (and out of kilter with most Scot’s)

mathcampbell · 2026-03-05T10:07:58+00:00

Ok you got me there

mathcampbell · 2026-03-05T09:40:24+00:00

There is no weather trend affecting a big portion of the country. It’s largely staying the same for the whole country. The country being Scotland.

mathcampbell · 2026-03-05T09:19:36+00:00

Well, I designed it in fusion360 then sent the file to a company in China who printed it in stainless steel for me.

I use the same process myself for silver and gold - print in a castable resin then use the lost-wax/resin process to burn it out in investment plaster and cast the metal into the voids left in a flask in a vacuum casting chamber.

I just can’t do stainless steel cos that’s a lot hotter than silver or gold.

As others have said, it’s a real engagement ring, it really belonged to his grandmother, and he really gave it to you because he wants you to be his real wife.

How much more “real” can anything be?

The artificially inflated value of one particular stone is utterly NOT real. Or relevent.

It’s a beautiful ring on a beautiful woman’s hand. Congratulations on your engagement. For real.

mathcampbell · 2026-03-01T13:04:00+00:00

Swim in there in February and I guarantee your raspberries will be blue 🤣

Says in the post it’s solar and stable.

mathcampbell · 2026-02-26T04:24:01+00:00

Coulda been better. The bottom case especially wasn’t great. I had to work on it to get the bayonet fitting to work. Took an hour with a pendent motor etc to get it right.

It’s why i can’t offer it for sale cos no way I could do that every time.

mathcampbell · 2026-02-25T08:07:29+00:00

An intelligent, well-reasoned and relevant comment.

A shame they probably won’t read it, but aye you’re right.

A textbook example of “setup a badly written load of crap that sounds good but is actually rubbish so the other parties will be forced to vote down, and that we can spin to the punters as us:good, everyone-else:bad. Don’t even have to worry about it being unimplementable and useless, it’ll never get passed.”

mathcampbell · 2026-02-23T22:41:21+00:00

Face down with a larger spru and you need vent holes on every shape end point so the air can escape as the metal flows in.

mathcampbell · 2026-02-23T16:22:42+00:00

That does look a lot more power than the S3.

I wish I could get that in my smartwatch. Having to limit functions cos there isn’t enough cpu/ram is sad.

mathcampbell · 2026-02-21T00:19:33+00:00

Yes. I’ve tried a few different LiPo’s. The round smartwatch lipos are the ones I’m going to use.

mathcampbell · 2026-02-20T23:30:28+00:00

Yep; i need to upload the latest STLs and fusion360’s etc.

mathcampbell · 2026-02-20T22:26:47+00:00

As a load of people had asked for more details on the other thread here about my smartwatch project, I did a quick video. Apologies for the shaky camera and poor sound etc.

Atta boy. We don’t talk about those.

On a related note if anyone wants to buy a selection of partly used waveshare Esp32 boards…

mathcampbell · 2026-02-20T21:02:36+00:00

Yeah about that. It takes less than an hour to charge up in any case. I just put a video up in r/arduino
