"We have a thermal printer hooked up to the internet, you can send us a doodle"
- JohnMakin 3y agoBold. I imagine they get a lot of phalluses.
- quectophoton 3y ago... that would still be one of the best case scenarios.
- binarymax 3y agoI've had an open doodle program at https://max.io/bash.html https://max.io/bash.html for 10 years. About 5 years ago I realized all the shared doodles went into the nginx logs as urls. So I extracted them to see what people were drawing. 90% phalluses.
- jstarfish 3y agoEverybody acts surprised about this, but nobody bothers to cater to what is clearly an underserved market of men who want to draw and exchange crude drawings of penises. Rename the app to "Gloryhole" and watch as all interest evaporates despite explicit permission.
- GTP 3y ago502 - Bad Gateway. Is the whole internet trying to print on their printer? ;)
- rpastuszak 3y agoYeah, I think they got hugged to death. I took a screenshot of the page: https://imgur.com/a/5mYanzV https://imgur.com/a/5mYanzV there's also this twitter thread: https://twitter.com/goodenoughllc/status/1714780523011121340 https://twitter.com/goodenoughllc/status/1714780523011121340 They cut and scan each message manually, so this is labour of love.
- dizzydes 3y agoSurely they could grab a digital representation along the way? I see scaling issues, will struggle at Series A...
- deleted 3y ago[deleted]
- tetrep 3y agoNot sure how this is hooked up, but there can be quite a bit of heat generated if it's possible for people to print (lots of) fully black pages, like wasting someone's fax toner/ink but with a risk of fire.
- bArray 3y agoI imagine the engineers of the printer thought of this and that there is a thermal cut off.
- rpastuszak 3y agoI think this is just a regular thermal printer. No risk of fire. Source: I'm doing something similar with a Cat Printer: https://untested.sonnet.io/TIL/weekly/40#Cat+printers https://untested.sonnet.io/TIL/weekly/40#Cat+printers
- mdrzn 3y agoRecently bought that same printer on Temu for like $5 so this is very interesting. Would love to connect it to something allowing me to control it remotely.
- rpastuszak 3y agoThis might help: https://untested.sonnet.io/Cat+Printer+–+tools+and+resources https://untested.sonnet.io/Cat+Printer+–+tools+and+resources Easier to set up if you're using a PC/Linux/Intel Mac as there are some issues with ARM/Apple SoC. Start with the repo in bold.
- internetter 3y agoOh, you did https://sit.sonnet.io/ https://sit.sonnet.io/! I love "useless" websites like this, there's just something comforting about them that I can't quite place. For whatever odd reason, this particular one randomly reminded me of this brilliant package: https://www.npmjs.com/package/emdash-extending-forever-into-the-universe https://www.npmjs.com/package/emdash-extending-forever-into-... Keep up the good work :)
- Simulacra 3y agoI hope safeguards have been put in place. Immediately, I thought about "black faxing." https://en.m.wikipedia.org/wiki/Black_fax https://en.m.wikipedia.org/wiki/Black_fax
- dale_glass 3y agoNot much of a danger. Thermal printers don't use ink, only paper, and are typically for industrial uses so should have no problems with that.
- shaunpud 3y ago[flagged]
- quickthrower2 3y agoReminds me of 20th century web! Nice. Not working on iOS :-(
- mat_epice 3y agoiOS didn't exist on the 20th century web, so... ;)
- sumtechguy 3y agowe called it macos then :)
- mrshawnliu 3y agoIt should work on your phone. But the site is being slammed right now... Sorry about that!
- rodlette 3y agoFor backup purposes, I'd like to print some encrypted secrets as QR codes. I don't have much room for a typical printer. Could a small thermal printer print a QR code that encodes 500-1000 bytes? If not, anyone know of a decent, durable, low-volume alternative?
- dddw 3y agoThermal prints fade pretty quickly
- user3939382 3y agoYes although any thermal printing I've ever done creates a print out that fades over time, so probably a horrible solution for backup codes.
- lazyatom 3y agoIf you just want to watch the live stream, you can see it here: https://guestbook.goodenough.us/thanks https://guestbook.goodenough.us/thanks
- toxik 3y agoThe guy spamming all black is funny, as if it's going to run out of ink. It's a thermal printer.
- DanAtC 3y agoMight cause it to overheat
- JBiserkov 3y agoOr fall over http://www.penzba.co.uk/GreybeardStories/TheBlackTeam.html http://www.penzba.co.uk/GreybeardStories/TheBlackTeam.html
- jstarfish 3y agoThis used to be a fax machine "prank"/DoS-- put black construction paper into the hopper, then tape the out end to the in end as it emerges so it forms a "drum" of black paper that continuously feeds. Fax that to someone and it ties up the phone line while wasting all the receiver's ink and paper.
- fullstackchris 3y agohaha incredible! for every single system out there, always seems like there is someone trying to exploit it :)
- ge96 3y agoSo interesting everyone's unique doodle like the split centipede thing

- mrshawnliu 3y agoHi guys, thanks so much for all the love you're showing our thermal printer project! As you've probably seen, the sudden HN traffic has been a bit overwhelming for our site. I'm with Good Enough, a small collective of six friends. We're not venture backed, and our guestbook is really just a little art project. We honestly made it for the fun of it, and it's not for profit, and it wasn't designed to scale. :) Please take it easy on our little printer! And do take a moment admire all the lovely drawings people all around the world have created. Each print has to be manually scanned in (I put the prints over old comics and scan them in on a flatbed scanner), so it'll take a while for today's drawings to show up on the gallery. The technology behind it is quite cool and you can read about it here: https://guestbook.goodenough.us/info https://guestbook.goodenough.us/info (Sorry, but the site might be slow right now...) And if you're curious about our other work, here's our site: https://goodenough.us https://goodenough.us Thanks again, and hope the rest of your day is fantastic!
- naikrovek 3y ago> Each print has to be manually scanned in Seems like it would be easier long-term to just keep a copy of what the browser sends to your server, then display that instead of the scanned print itself. Even if you generate the printer bytestream in the browser and just `cat` whatever comes in to your printer device, it would probably be faster (again, long-term) to write software which can render that data stream to an image. but as an art project, it's perfect. is the source code anywhere?
- lazyatom 3y agoWe can indeed do that, but as you correctly identify, a purely-digital copy would undermine the aesthetic :)
- lazyatom 3y agoThe code for the guestbook is not open source, but it's built on this open-source platform: https://github.com/exciting-io/printer https://github.com/exciting-io/printer
- anfractuosity 3y ago
- alnwlsn 3y agoWow! That's much fancier than the one I made. I got bored and never implemented anything other than text. [http://alnwlsn.com/printer/ http://alnwlsn.com/printer/]
- plastic3169 3y agoIs the time(zone) coming from users? Would make more sense if it was local to printer.
- capitainenemo 3y agoThe guestbook images load very very slowly. Probably because they are quite a bit larger than their preview boxes and also PNG. Simply re-encoding with mozjpeg at 85% (which still looks darn good to my eyes) without rescaling in case you wanted the larger size for retina displays. $ ~/git/mozjpeg/cjpeg -quality 85 ge-printer-231017-zenwheel.png > temp.jpeg $ ls -lh temp.jpeg ge-printer-231017-zenwheel.png -rw-r--r-- 1 nemo nemo 439K Oct 18 19:04 ge-printer-231017-zenwheel.png -rw-r--r-- 1 nemo nemo 77K Oct 19 09:20 temp.jpeg Aaand reduced a touch so it still should look good on HD, and cranking up the jpeg compression slightly. $ convert ge-printer-231017-zenwheel.png -scale 75% temp_smaller.png $ ~/git/mozjpeg/cjpeg -quality 80 temp_smaller.png > temp_smaller.jpeg $ ls -lh temp_smaller.png temp_smaller.jpeg -rw-r--r-- 1 nemo nemo 41K Oct 19 09:23 temp_smaller.jpeg -rw-r--r-- 1 nemo nemo 268K Oct 19 09:22 temp_smaller.png IMO that would help the page load 10x faster, if you just piped the images through a bit of scaling and jpeg compression.
- mrshawnliu 3y agoYou're right! Thanks so much for pointing this out, capitainenemo!
- SSchick 3y agoOpened stream, immediately saw goatse, you might want to detour `drawImage` and booby trap it to ban anyone using it on the canvas (this is what another website did for a similar project).
- SSchick 3y agoThe backends accepts raw HTML markup and people have (unsurprisingly) busted it now, you need not trust the client to send sane data.
- lazyatom 3y agoHey folks, the live stream of doodles is shut down for now. While some of you created some really beautiful doodles, or silly doodles, or both doodles, some other folks decided it was a great place to spew racist and vile imagery, and it's not right that we broadcast that back into the world. This is why we cannot have nice things.

- dirtybirdnj 3y agoIt appears I'm about five hours late on the internet hug of death you guys are experiencing. Looking forward to reading when I can access it :) Congrats on making something interesting enough to cause you this pain.
- dirtybirdnj 3y agoUpdate: I made it in! I added a drawing! Hello from Vermont :)
- bcjordan 3y agoLmao I love this. Is there a collection of these sorts of real-time experiments? Every so often a remote control robot to printer will come up on here/back in the day Slashdot/Reddit/Fark and it's loads of fun. I remember having a great time as a kid trying to flip the Plantraco remote control car by driving up the corner of the wall

- asoltys83 3y agoI went on a bit of an odysee creating "smart" thermal printers this summer in an attempt to build something suitable for giving Bitcoin payment notifications to merchants. I started with battery-powered Bluetooth-enabled printers but found that the ESP32 microcontroller I was working with had trouble connecting to both WiFi and Bluetooth at the same time. I ended up going with another printer model that supported TTL serial connections and landed on the ESP32 C3 board which has a very small form factor and was able to squeeze inside the case that comes with the printer. Here's a video showing the end result: https://www.youtube.com/watch?v=JiGoOJZUrP8 https://www.youtube.com/watch?v=JiGoOJZUrP8 Skip ahead to 2:40 if you don't want to hear me talk and just want to see the build video where I connect the ESP32 to the printer.
- tanseydavid 3y agoWith my WACOM tablet and stylus I cannot "lift" the pen off of the page. Once I start marking with the pen, it continues to draw continuously from point-to-point even when lifting the pen. It acts as if I never lift the pen, once I have made contact and start drawing.
- greeniskool 3y agoSame here on my Android phone running Bromite. As a workaround, you can switch to the eraser tool and then back everytime you lift your pen/finger — although its not really ideal ^^' Edit: Pressing the "Redo" button also works
- briandilley 3y agoWhat was the TTP for this experiment?
- red-iron-pine 3y agobetter hope 4chan doesn't get a hold of this
- sen_armstrong 3y agoKinda like the old oekaki boards, eh? Forums where you drew your posts with tools embedded on the page. The pen here ought to draw without anti-aliasing for authenticity ;) Here's a page from a Japanese board, 20 years ago to the day: https://coolier.net/oekaki/173.htm https://coolier.net/oekaki/173.htm From the nearly sequential unmoderated post IDs, one surmises its visitors were a little more... civil than HN has been today. ^_^ Here's a western one, 2008-2015: http://archive.tewi.us/tegaki/showtags.php http://archive.tewi.us/tegaki/showtags.php This forum had no text entry! All comments were handwritten and drawn. Its last days saw what might be the most expressive biddings of farewell ever posted on the web: http://archive.tewi.us/tegaki/sortbytag.php?t=1&p=2 http://archive.tewi.us/tegaki/sortbytag.php?t=1&p=2 Is it a coincidence both sites are Touhou-themed? What we can see is that the second had a lot of tumblr users... Right! 4chan still has an oekaki board, one of two boards with special UI. The editor (tegaki.js) records lossless replays as proof that posts are original. Fitting the theme, you can watch a Reimu being drawn here in 39m51s: https://boards.4chan.org/i/thread/699320#p737995 https://boards.4chan.org/i/thread/699320#p737995 - That kind of linework with no anti-aliasing is something special when displayed unscaled at the right DPI. I think it's the crispness that makes it pop. Same with Easytoon animation: 1-bit 160x120 GIF can look this good?
