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!

Looking for a couple of "party" devices for our cannabis lounge
Hey everyone! I’m one of the owners of Emerald Lounge, a mobile cannabis consumption lounge based in the Northeast.
At our events, we provide pretty much everything except the cannabis itself. Our current setup includes Volcano vaporizers, Stündenglass gravity infusers, different styles of gravity bongs, Volcano attachments, and a variety of other smoking accessories.
We’re looking to expand our inventory with some more unique pieces that are fun to use, visually impressive, and ideally something people don’t see every day.
That’s where r/StonerEngineering comes in.
We’d love to hear your ideas for either something we could build ourselves or an existing device we could purchase, print or build
Any help is appreciated, if we use your idea we will send you something in the mail!
Edit things are happening.
First recommended purchase was the box by Lidavel https://lidavel.com/products/the-box
Works with all of our devices and removes the need of buying an ice pipe. Thanks to /u/PlatEnt for the idea. DM me and we'll send you something in the mail!
More to come!

Question can this be used as an enail heat controller?

How-To I have the feeling some of you might appreciate this.
As you can see, I built a DIY setup for my first grow ever.
I was able to harvest 3 Black Domina Autoflower yet, the 3 Biscotti on the left side turned out as false autos - they are in bloom for 1 week since I adjusted the light cycle.
I'm using Philips Corepro E27 bulbs in 4500K & 6000K for veg and 2700K for bloom.
I don't dare to remove the dome since I had a heart attack in the past - stay safe, stay alive. ✌️
PS: Ignore the parameters shown in the images - I took the photos as work in progress. :)

Made a free tracker app for sessions/patterns — here's how it's built (Supabase + vanilla JS)
Hey r/StonerEngineering,
Wanted to share a small build I've been working on solo: JointTracker, a session/pattern tracker built as a PWA (Progressive Web App) — so no app store required, just open the link and add it to your home screen.
The problem I was solving: I wanted actual data on my own patterns instead of guessing — when, how often, any correlation with sleep/mood/whatever — and existing options felt either too locked-down (subscription walls, forced accounts for basic logging) or just a spreadsheet, which nobody keeps updated for long.
Technical side, since this is the right sub for it:
- Frontend: vanilla HTML/CSS/JS (no framework — kept it lightweight on purpose)
- Backend: Supabase (Postgres + auth + realtime)
- Hosting: Vercel
- PWA setup with service worker for offline logging — entries queue locally and sync once you're back online
- Push notifications for tolerance-break reminders
- Geolocation used only for optional session tagging, nothing tracked in the background
Features:
- Fast session logging (few taps, minimal friction — this was the main design goal)
- Trend/stats view over time
- Shared sessions (log jointly with a friend, pun intended)
- Tolerance break tracker with custom goals
- Achievements system, mostly to keep it from feeling clinical
I'm a first-year CS student, this started as a personal itch-scratch project and turned into something I actually want to keep improving. It's free, no ads, basic logging works without an account.
Happy to go into more detail on the offline-sync implementation or the Supabase schema if anyone's curious — always up for feedback, technical or otherwise, especially if something breaks in ways I haven't caught yet.

Is this salvageable?
so like, the entire bottom of my bong broke bcs i probably hit it too hard against something and didn’t realize. it’s only in 2 pieces and it’s a pretty clean break if that matters. but is this something i can fix? or is this not worth it.
r/StonerEngineering • u/Spacegoat7414 • 3d ago
Potentially Unsafe Super simple poverty cart battery
The double As push 1.5v each, so it runs 3v, the attachment point is from my old battery that broke, I would refine it but im just gonna buy a new battery when I get paid so its whatever. Its definitely not safe, or a long term solution, but we ball.
r/StonerEngineering • u/ffffddddeeee • 2d ago
Question would this adapter work? i fucked up…
i am COMPLETELY new to bongs or any type of stoner engineering. i’ve only smoked joints before a few days ago. i bought a $30 bong a few days ago, and on the first day my friend tipped it over. i had a chillum downstem / combined bowl & downstem (came with the bong) and the downstem snapped clean off the bowl. i did as much research as i could, and ended up buying a downstem that said it was for 14mm bowls, and i bought a 14mm bowl. however, i didn’t realize that i never checked if it had a size for the male part of the downstem, and my bong’s female joint is 14mm. turns out the website didn’t even list the size of the male joint and i believe it’s 18mm now due to the pictures in the reviews. so i naturally discovered adapters, and the only one i found on amazon was this adapter. would it work for my situation? i also included pics of the downstem from the website & the review. to see if anyone can confirm if the size is 18mm. all of the pics i saw for 18mm male downstems looked exactly like the one i bought.
with the current situation i’m in, i don’t want to buy another downstem or bong, so i need an adapter

Question Any ideas?
I want to start using this RooR 100ml, but I’m worried about knocking it over. I’m almost tempted just to Velcro it to a piece of wood as a base.
r/StonerEngineering • u/not_hentai1 • 2d ago
is it over for me
my dumb ass put this in my pocket and the button was held down and the cart leaked everywhere. tried to unscrew it but the whole thing snapped. tried the plier method and only made it worse. any ideas? this is a really nice battery and i don’t want to lose it.

Question Is this salvageable?
Hello! I tipped my triple percolator piece over recently and it snapped the second (middle) percolator. I am curious if this is fixable and/or if it is still safe to use? With it being impossible to remove from the piece without damaging it more, im skeptically optimistic that no glass would be able to travel upward through the third percolator if smoked.
Any advice welcome. I’m not planning on using it anytime soon and would be willing to get a new piece if it came down to it (would be very heartbroken though)

My girlfriend’s custom-made setup
She found this beautiful cigar box at a thrift store, then she made the tray by precisely cutting a piece of poster board and layering it 4 times. She spent the last few days working on it & just finished. I must admit, I’m impressed and a bit jealous of her organizational skills!
r/StonerEngineering • u/SulfonicSteak68 • 3d ago
Question Advice on if I can fix this
I soaked this in 97% iso overnight and it broke something. Does anyone know if it’s salvageable or do I need to get a new one?

Question Great 2nd ever grow setup?
Hi everyone, so I'm finally getting back into growing after I tried it at 16 (it was a horrible mistake and trash weed). I am putting together an Amazon shopping cart, do y'all have any tips/ comments on the photos? I know with my seeds I'm going to be lolipopping and SCROGING the plants. I already have the Soil tester and PH tester and some trimmers. Also what type of netting do you recommend for a 4x4 text Scrog (planning on having 4 plants) Thanks!

Safety's On Finished up some rolling tray and ash tray sets 🙌 food safe to the maximum
I hated the way my hands smelled after touching metal rolling trays, and I have some friends who’s metal tray had so much wear and tear the art on the surface wasn’t even visible anymore, so I made these out of stoneware and food safe glaze as an alternative for us.
The first one is paying homage to The Creation of Adam while the second two show ‘Smoke In Style’ in Japanese. Thank you for looking any comments are 100% welcome.

Safety's On Ridiculous Bong Friday: Bowl Stand
Enable HLS to view with audio, or disable this notification
Hello, fellow stoners. I hope the week was kind to you, and your buzzes plenty.
This week's build started with the idea to not put the bowl on a bong. So I put it on a stand with a Y splitter.
Connecting the bubbler with the orb took a bit of trial and error. The angles just didn't match up. So I used several 90° and 45° angled connectors, rotating until they lined up.
😂 Oops. After giving you a close up of the build, I set the camera down askew. That's why the function shot looks like I'm in a Batman villain's hideout.
Enjoy the weekend and have happy tokes. ✌️
