Moderator's pick Moderation Update

117 Upvotes

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

22 Upvotes

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!

Studying while being a full time stoner

12 Upvotes

Hey all, I'm currently a 2nd year mechatronics student who loves a bit of ganja before bed and tbh I'm not getting the greatest grades ATM. I didn't really develop a study habit in high school as I found most of the concepts quite straight forward, while I was still blazing up, but it's obviously not the same in uni so this could be the cause of my problems.

I find the brain fog and the lack of memory retention has gotten quite concerning but I'm wondering if there's anyone out there who completed a degree as demanding and involved as this while being a full time stoner, and if so, how did you find it affected your studies?

Prototype Microplastic concern?

Post image
33 Upvotes

Is the main concern with 3d prints and accessories and or displays, and the concern with microplastics when a smoking surface or tool surface that makes contact with plastic ?

I tried to mitigate plastic contact with a cork base in front.

the tool holders are interchangeable so contact is dependent on tool used and stand paired with.

The cap and marble holder was enlarged to accommodate 35.8mm glass wax containers to use as a cap holder. Its what I had been using for years but can now fit in display.

Prototype My custom made stem for my Dynavap

Thumbnail

7 Upvotes

This is a repost, I had to delete my previous post and I am reposting it for reference when I refer to my custom stem experiment in the future.

This is Gr2 Ti, 10x1mm. If you intend to make your own do note that Dynavap tip is not exactly 8mm and your tube's inner bore might also not be exactly 8mm. So ready your sanding tools because you will need to widen the bore a little to fit the tip in. I'd say it takes about 20-30 min to widen the hole enough for the DV tip.

The sizes: 62mm, 115mm, 180mm. Condensers are of the same length.

62mm: I have 2 of these. I thought I would be using these the most but it gets a little too hot for my convenience. Flavour wise this is the best.

Flavour: 9.5/10

Portability: 10/10

115mm: This is my daily driver. I didn't think I'd like it this much but it's the best balance between flavour and vapour temp. I'm planning to make the airport longer though.

Flavour: 8.5/10

Portability: 8.8 (not palmable, needs case, but still fairly portable)

Cooling: 9.5/10

180mm: This is just something I needed to do. I didn't think it would be great. I made this for one specific objective: cooler vapour. And yes the vapour is very cool. But the tip also loses heat too quickly and a lot of flavour is lost. This is pretty much only used for the wow factor and is only one step above wet bong. I bet if you put a heavy tip and armored cap this can be a beast too. At 180mm the heat is too far away to reach the airport which i made close to mouth area so it can cool the condenser along the way.

ALSO at this length, the 5x0.5mm tube can be very bendy. Exercise caution.

Flavour: 6.5/10 Portability: 4/10 (but 10/10 if you're LARPing as a techno wizard) Cool factor: 10/10 (just bonk those who disagree)

Original plan was to update the airport, sand it to smooth finish, anodize the outside to aqua green and the condenser to gold. But if that's to happen at all it will take a lot of time as I work a finance job and don't touch power tools at all in my day to day life.

My next project is a couple custom Miniwynds using native woods grown in my land. This will probably happen a lot earlier than anodizing my Ti stems lol.

Thank you to everyone who posted guides on how to make our own Dynavap stems.

Thank you to the couple of people who suggested the Dynavap Maker's Kit instead of the M7. It kick-started all this and I enjoy this journey very much.

Edit: more info for the 180mm stem

Hello, fellow stoners. Friday is here, and so is another crazy bong setup.

Today we have basic engineering with basic shapes: a circle, a square, and a triangle. Three shapes, three bongs, three rings for the elven kings ... oops, I got sidetracked.

Enjoy the day, enjoy some weed, enjoy life. Happy tokes. ✌️

Former stoner here- I share this bong cleaning tip whenever I can.

Post image
179 Upvotes

Puro Caffe (Puro) commercial espresso machine cleaner is the absolute best thing I have ever used to clean bongs. Cover both holes, add 2 tbsp of the powder, and add hot water to fill the beaker. It will begin to foam up and spread throughout the bong. Let it sit for a while and thoroughly rinse. Minimal shaking required. It makes your bong literally brand new, and it is completely food safe. I figured this out while working at coffee bean when I was 18. If you give it a shot, let me know. I smoked moles everyday so my bong stem and bowl would get gunky fast. Because of this, the salt and alcohol did not work as well for me. It got it relatively clean, but not brand spanking new. Bottle of this stuff lasts for ages.

I love how the clamp from the set works so well as a joint clamp between the bowl and the 14mm male piece

Neat No more messy stoner 😛

I've had enough of everything being everywhere and I have therefore decided to actually start to put things in places where I know they'll be. a simple concept, but a lot of work has been put in to understand it.

A messy room is like a negative feeling to me. a loss of excitement coming back to my room.

I would clean but the mess would come back because I had no organisation.

Not much stoner engineering going on but I am very proud of my box box box made of my vape boxes which is now for rolling papers. I also believe that there is no harm in applying my creativity to improve not only my smoking experience but my life itself.
