Something to note is the impermanence of the final product, as thermal paper does not have longevity (only ~1 year). I have not found a similar solution (printer + media with a similar form factor) where the print lasts longer, so open to suggestions for such use cases. I suppose in the short term, including a QR code in the print job that links to a perma/deep link online might work from a publishing perspective for…

I really have fallen for impermanent art. I display slide/color positive film on my windows. Yup they will fade and that’s totally ok.

Huh, that's very interesting. I've always considered Art to be timeless, bc it is, all of it. Davinci did a lot of cool stuff but the Mona Lisa made him the most famous person and I really don't see that changing. I have a painting hanging over my head rn whose artist died in the 1680s - the painting is over 100 years older than the Declaration of Independence and was brought over here on a ship with sails that took forever.

Impermanent art. That just bothers me.

An artist that dedicates their life to such a thing is like swimming in the fountain of youth without ever taking a drink.

> you should not make a pipe out of a coke can because of the plastic liner I'm fairly sure it doesn't make much of an health impact considering the hot smoke you pull into your lung, but when I was kid and we made pipes out of cans in "emergencies" we'd use the outside of the can as where you put anything with fire, you don't have to turn it inside out to be able to smoke out of it.

> we'd use the outside of the can as where you put anything with fire, you don't have to turn it inside out to be able to smoke out of it. This is what I pictured, but now I'm curious how you'd use the inside of the can.

Some stoner-engineering could hook up two cans with each other, one is the cup you use for burning the material and the other one the "water-passageway". Obviously not recommended as there is plastic liner on the inside, but in that way you could use the inside :) Basically a bong in two pieces made out of two cans.

I have wanted to do experiments with a receipt printer hooked up to a Raspberry Pi, with some simple controls... but every time I look up the cost of the printer I balk. It's probably not fair, but I guess in my head it feels like they should be cheaper. Or at least the cost then makes me question how much time I'm really ready to put into stuff like debugging the printer drivers and putting together a case, etc etc.…

I recently bought a thermal ESC/POS printer for 25 Euros on Aliexpress but I saw the sames ones for 30 Euro on Amazon. I connected it to my linux server and without any drivers I can print with e.g.: `echo "Hello World!" >> /dev/usb/lp0`. It also supports bar/QR codes.

You have a make/model/link?

If you do this be sure to buy BPA free receipt paper Handling receipt paper is what turned out to be the cause of the high BPA numbers when boba tea was tested https://x.com/natfriedman/status/1899641377002025252

You do know that BPA-free just means they use BPS or some other bisphenol plasticizer, right? Right? Because all of the research was focused on BPA and nobody tested BPS even though they're quite similar chemically.

You just can't polymerize plastics without a plasticizer. It's just not allowed by chemistry. No free lunch.

If you want something that's not going to leach huge amounts of plasticizers onto your fingers, use an inkjet or a laser toner printer or a laser marking machine.

They don't really make those for receipts, though, because fingers tend to be wet and powdered toner is expensive.

Heating up plastic gives off all kinds of really nasty organic compounds, far worse than the drug... doesn't need to be direct flame.

Heating plant material also gives off lots of carcinogenic stuff, tar and so on

Cheeseburgers are bad for you, but you shouldn't put motor oil on your cheeseburger...

My wife has a little thermal camera (Vivitar Instant Camera) that she takes to parties and events. The picture/print quality is a bit better than a gameboy camera, certainly not HD, but also fractions of a cent per picture rather than a dollar like you'd pay for a Polaroid. Fun stuff.

I bought some for my nephews (age 3-4), it's a lot of fun, because it's instant physical feedback.

Also if you buy a pack of BPA-free paper rolls, you get a crazy amount of pictures for $20. Granted you'll have to re-roll them into smaller rolls to fit the camera.

I wonder if the author is aware of the health effects of handling thermal paper. https://pmc.ncbi.nlm.nih.gov/articles/PMC5453537/

There are alternatives like Blue4est available, though. They don’t use bisphenol or other chemical developers.
