Did anyone use the heat transfer of a frying pan to transmit a transaction yet?

Would be a nice weekend project: create an air-gapped transaction, build a little device that heats up a frying pan on one end, and once it hits a certain temperature threshold (measured at the other end) you book it as a binary ONE, and if it doesn't hit the threshold in a certain timeframe you book it as a binary ZERO.

The frying pan would literally act as a transmission device, and once the binary string is transmitted through the pan, you broadcast it to the network by whatever means. Bonus points if you broadcast via ham radio, just for the heck of it. And also because you could give it a nice name like "Ham in a Pan" πŸ₯“πŸ³

Stainless steel or cast iron?

Asking the real questions!

Sending is doable with a PWM signal to turn an electric stove on and off. I’m not sure about reading the address part though, maybe an LM35…

I'm glad I'm not the only one that was thinking about this.

Heat transfer as a low time preference binary signal. Or find the resonant frequency for faster transfer.

This is the kind of content I had been craving

Can I cook some ham in pan at the same time?

It won't work otherwise.

Or even better: spam!

Reading this I realised you kept thinking if you could… but never stopped to think if you should x)

Fun fact, this is a post exploitation data exfiltration method for airgapped devices.

Not so much the frying pan, but more CPU and room temperatures.

Unrelated but I see you pixelated your avatar. Wise choice, who knows how crazy their military grade facial recognition is gonna get.

Your friends in NYC had the same idea!

Love to see it πŸ”₯

I once wanted to build a system with taggers and janitors. Each scream of the janitor would be a bit. Needs some error correction though because of interfering skaters.

What is the carbon impact of this?

Modern day smoke signals!

On a related note, this guy has a project to transmit #ecash over Reticulum so it supports HAM and LoRa as well as WiFi:

donΒ΄t forget to register the frying pan as a money transmitter

Do I need a hot wallet for this? No pan intended.
