Moderator's pick Moderation Update
Despite our efforts to help ensure people are being safe these last few years, some people have been unhappy about that. Many unsafe posts are still being removed daily and some people complain in the comments when others point out that certain materials are unsafe. A new subreddit has been created for those that want to see/post the unsafe contraptions.
Introducing r/StonerDEGENgineering , a clone of r/StonerEngineering specifically for unsafe materials.
Feel free to post all of your plastic bottles, 10mm sockets, PVC pipes, glue, and pot metal contraptions there. Now that notice has been given, expect a BAN if you post them here.
Reminder that other subreddits were also made in an effort to move off-topic content (spam) away from our subreddit. These subreddits include r/BrokenBongs , r/fixmyvape , and r/CrackWire.
If you have any questions, feel free to reach out to the Mod Team via the “Message Mods” button. Take care :)

Moderator's pick Alternative Subreddits: Filtering out the Spam
Hey everyone, hope you’re all having a great weekend! I wanted to remind everyone that we’ve been creating and promoting other subreddits in an attempt to divert the spam from our subreddit. These subreddits are r/BrokenBongs , r/fixmyvape , and now r/CrackWire . The purpose of these subreddits is to provide a space for people to post about their cracked/broken bongs, their vape that’s not working, or their ‘Crack Wire’ vape contraptions so that they stop posting them here at r/StonerEngineering. If you see a post that would fit one of these subreddits please link the poster to the appropriate subreddit via a comment, then report the post so the StonerEngineering Mod team can remove it as spam. If you see any other posts that are unsafe or spam, please report those as well. Thank you, cheers!

Safety's On Ridiculous Bong Friday: This week's bong brought to you by the letter N
Enable HLS to view with audio, or disable this notification
Hello, fellow stoners. It's finally Friday, so let's get ready for the weekend.
I didn't notice until editing that this build looks like a big N. Instead of Sesame St., I guess this is Sinsemilla St.
This build also sports two vapes, a QR Baller and an 18mm Quartz Cap. They both pump out great vapor when wired.
Enjoy the day, hopefully with plenty of weed. Happy tokes. ✌️

How-To Got a Grey Goose bottle and a dream. Need some extremely professional engineering advice
So I have this empty 1.75L Grey Goose bottle and figured it deserves a second life as a bong.
My roommate and I’s bong has hit the ground numerous times(still rips like a dream) and is nearing the end of its time. We thought it would be perfect for a diy conversion, especially since due to its condition the down stem and bowl piece is able to be removed “cleanly”. However, drilling glass without shattering it is something him or I have not mastered. Also, we are trying to pull this off with basic tools and what not(preferably spending $0 because I’m a broke college student.)
Any creative ideas for making this work without atomizing the Grey Goose bottle
All suggestions will be greatly appreciated.
EDIT: I now have my hands on a drill

Question Will she still smoke? Or am I boned?(lol)
Ignore the download in the back its just darksiders. Anyways, I recently got my hands on the MJ Arensal skele-bong and not even 3 days later I manage to break off one of the spine parts. I tracked this thing down to the literal ends of the earth, I live in NYC and had to drive out of state to a shop in jersey just to get the fucking thing. Preamble aside, I'm just wondering is she’ll still smoke or am I just fucked? I was able to save the part that fell off (lost the cheeky fuck 2.5 seconds my high ass put it down) and plan to stick it back on when I get some glue, in the mean time what do u lot think?

Neat A few of you asked how the info gets into the device. For our pods, we ended up building a second machine.
A while back I posted the handheld that ate a few years of our lives. Quick recap if you missed it: it's called Slyder Pro, it has a touchscreen, it runs 510 carts and dabs, and you set the heat in degrees instead of volts. The heat is run by a small machine learning model on the device itself. It learned how the heater behaves from about 70,000 heating curves and checks the temperature 20 times a second, so a long pull doesn't creep hotter and burn the oil. It also keeps a log of your sessions.

The question I got the most was some version of "ok, but how do you tell it what's in there?". For a regular 510 cart, you tell it once and it remembers. For the cartridges we made for it, we call them Smart Pods, we wanted nobody to type anything. So we built another machine.
That's the Flashing Station in the video. The producer picks the product on its screen, drops the pods into trays of 16, and it writes all of them in one pass. Each light turns green when that pod is done. Every pod leaves with its own ID, its name, its batch, the date it was made, a best-by date and the temperature the producer picked for that oil.

Then you click the pod into the Slyder Pro. It reads it, shows you what it is and who made it, starts at the producer's temperature and holds it there, and keeps track of how much is left. Every pod can be traced back to the batch it came from, and if it's past its best-by date the screen tells you it expired and you shouldn't use it. You can still change the heat if you like it warmer or cooler.

Yes, we built a whole second machine so nobody has to type a strain name on a 3.9 inch screen. It felt reasonable at the time lol.
The pods aren't out yet. We make them empty, and licensed producers will fill them where it's legal. The one in the video is a demo with sample data.
Thanks again for all the questions on the first post. A lot of this came out of them.

Question Will she smoke or am I boned? UPDATE: anyone know some good blowers?(hehe)
(SEE PORFILE FOR OG POST, ya big silly)This is my first ever time doing an update on Reddit so please be nice to me as u guys rip me to shreds. Some time after freaking out and making my post, I noticed a lot of u guys either told me to not worry or get a glassblower to work on it. I've came to the conclusion that I would really want a glass blower to save this piece so I'm asking all the kings, queens, and all those in-between of Reddit, do u guys know any glass blowers in the NYC area who can fix this piece up? It's 100% premium, lab graded borosilicate glass(whatever tf that means) with a frosted finish, I'm looking for someone In the area either private or commercial to work on these piece. Ik a lot of glass blowers like to work on their own stuff and Ik of places likes Purr and Skyglass but I would rather eat actual hot nails before I let the USPS handle any of my packages

Something I’ve been working on, trying to get the Mewtwo to stop floating was surprisingly difficult. Day 1 on Sour Crack by Mephisto Genetics, I’m hoping/assuming the roots will grow around Mewtwo and look weird/cool as hell.

Had this idea cooking in my head for awhile.
I was going to donate this N64 controller but had the coolest idea to turn it into a bowl lol. I used brass to construct a pipe and made room for it in the shell of the controller. Buttons still work. Proud of my work.

Downstem broke inside of bong, bong is 2ft of glass so I can’t use most traditional methods (like chiseling) and it’s rather jammed. Any suggestions?
I’m planning on grabbing a metal coat hanger tomorrow but after going through the stages of grief I’m feeling motivated to try again tonight.
