Well, its $18 for a hot dog and a drink, and also the cost of labour and transport to get them to your door, and little bit for admin costs.

So if, say, the delivery person can do one every 20 minutes, that's $54 of revenue an hour for the company, minus, say, $10 for the actual food/drink items, $20/hr to employ the person, plus 3 x trips at, say, 5 miles per trip at like, 25 cents/mile for fuel and maintenance, so $3.75 for that.... so about a 80-100% markup on cost for basic labour and expenses, which is where businesses generally need to be on markup to keep afloat.

The other option is to go get one yourself I guess, but if you value your time the costs end up being approximately the same.

Working in IT/OT, It's a neverending battle:

OT wants to open things up. A huge amount of utility is gained when things can be monitored and operated remotely.

IT wants to lock things down. Access to systems should be reduced to the minimum amount possible to lower the risk of Bad Things happening.

The battlefront shifts back and forth depending on business needs and budget.

Depends what software and build system you are using on the 8266. I've had ESP32 modules that had flaky wifi in Arduino run fine when running a project built with ESP-IDF. Maybe grab the 8266 RTOS SDK from Espressif and build a test wifi example with it and see how it goes. The SDK is quite old though, so your results might vary.

I would be cautious about using these models (or, any general purpose LLMs really) for mental health or companionship chats.

They're all generally agreeable to your point of view, which can reinforce the wrong things in your mind. I'm not sure if prompts in the harness could make them generate dissenting or outright adversarial/challenging responses, which are the things that people often need to get out of the rut that they're in.

Looks fine. Mayyyyyyybe the 1k resistor is a little high, depends on the gain of the transistor. 5 volts would feed it with 5mA on its base, which might not be enough to fully switch it on. However, as it's only driving the relatively high resistance coil in the relay it's nothing to worry about if it works.

If you were driving it with 3.3V, I'd probably swap that transistor out for a Darlington pair to make sure the gain is high enough to fully switch on at that kind of drive voltage. You can get Darlington pairs in the same pinout as normal transistors so it would be a straight swap on the board.

Having said all that, if it's working in your application, leave it. 🤷

You can only flog off grandma's fine china to the pawn shop once. And then how are you going to buy smokes next week?

Everything costs billions to construct these days. We're going to sell already built and depreciated assets for that sweet cash injection now, and then a few years later it'll be all surprised-pikachu-face when we discover we're renting all sorts of fixed infrastructure at exorbitant costs.

(squints)

Looks fine up to about 6 amps I reckon, judging from the size of that relay. Not a huge high power coil on that so a simple npn transistor switching the coil to ground would be fine. Got a diode across the coil to catch the back-EMF, looks like all the basics are covered .Would only bother adding extra solder to the tracks for the relay contacts if I was doing it but that's neither here nor there.

Dunno what those eevblog folks are on about 🤷

I dunno, it's been like, 5 years..... I'm not sure if this whole world-domination-5G-injection-communist-new-world-order-plandemic-slavery thing is working out.... Maybe it's time to update the car with the next Big Conspiracy?

All current datacentre hardware is being run at power and density levels that hover somewhere between "operational" and "pile of glowing silicon slag".

I'm sure some enterprising Chinese companies will take all the surplus hardware and create underclocked "consumer-capable" versions for inference. I'd happily pick up a couple of cards that are 75% of cutting edge performance if they're a hundred bucks a pop.

But it's the sport of kings!

Careful research and knowledge of the horses, jockeys, and track is needed to select the optimal competitor for that cheeky $50 punt you put on while trying to use the self-checkout at Woolies. Don't tell the Mrs, she'll lose her shit again.

Ooooo wait, maybe it's the AI going rogue and trying to spread itself around, as foretold by the mad priests of Anthropic!1!1!!

We've got to lock down all AI models now!! Keep all the RAM in the datacentres for safety!! We can't allow this to happen! Not without a lot of money getting siphoned into billionaire's pockets! Won't someone think of the billionaires!?

I work with embedded devices that use canbus. Last week it was happy to read the manufacturer's published .DCF files for a couple of joystick panel interface boards. Not anymore, conversation flagged and halted any time I get near them.

Claude. You can download these files from the manufacturer's website. They only describe how analog and digital inputs get converted into canbus packets. I am not trying to hack Adobe here. Nope.

Oh well, DeepSeek, Mistral, GLM, Beam et. al. are all happy to read these files and continue work on the project. Anthropic's usefulness to me has ended, it was nice while it lasted.
