Now bear in mind this isn't a refined design but more of an initial planning design. Haven't tested the design either (still trying to find a cheaper source of test tubes without having to buy them by the case).



You can get rid of the heating bath, and water filtration to save money and the stove works fine for a heat source. Also you can get similar glass pieces from local places but make sure that any part that is heated is Pyrex. Thrift stores and yard sales are great and you could probably get away with doing this for well under 100 if you are willing to look.

Ok here is the basic design for the cheap model.

Forgot to put in the picture but you'll need tape to seal the balloon to the tubing.

I hope to start work on that in a week but I might not be able to.

How do you propose to control the temperature?

Rather than spend $100 putting such a device together, I'd rather buy a VaporWarez for $119.

Lab heater, a heating mantle with a voltage regulator, or variable power suplly, electric stove, gas stove, electric hotplates they sell at target (needs some modification so the temp is truly variable) any of those will work. If a thermometer is wanted all you have to do is drill an extra hole in the stopper for it (make sure you use a large enough test tube).

Eventually I'll probably cook up a custom heating element with a temperature probe in the weed so the heating can be controlled by a microcontroller, but thats a long way off since I've been spending most of my time trying to get my chem lab off the ground (big thing right now is finding a way to store my experiments and inventory on a search able database).

Also if you use your stove and crap you get at yard sales I'd bet you could pull it off with $20.

Also Edit: One thing to bear in mind about a heating bath, while it allows for more even heating of the marijuana and lessens wear on your glassware it also takes more time to get up to temperature.

Edit: Here's a quick flowchart I cooked up in dia

AK kronic2

To make a 3$$ vaperizor is to hallow out a light bulb and put and tape a bottle top to the top of the light bulb with a hole and a stray hooked up to it. IT WORKS GREAT but if somebody doesn't know your just using it for weed you could be in big trouble..

Noeone

But the point of this is to make a vaporizer that actually vaporizes at a variable constant temperature.

 

HerrSmokes

Haha, AK kronic has the right idea.

Want a hilbilly vaporizer also known as a crack pipe?

Hallow out a light bulb,I've done it... it works.

But if you want to make a legitimate vaporizer, the effort and expense would be more than just buying a small one.

Though i have heard of people using a soldering iron assembly for a constant temp. although it is not variable... just off and on.

*Edit... I HIGHLY caution you from using your beer bottle method. As some one who works with glass and knows what it can do and what it cant. The beer bottle being on a heating element like that is very risky. Your running the risk of it shattering, and i don't mean it just spider webbing. Beer bottle glass is not the glass your pipe is made out of, not even close. When that bottle heats up, there is a chance for a catastrophic shatter with shards of glass flying through the air.

Best stick to tempered PYREX glass if you plan on heating it alot. Or something that gets hot normally (like a light bulb for instance,this shares the same risk, but its heat threshold is much higher)

the cheapest vaporizor i can have made was get a beer bottle drink it throw the cap out it has super glue on it DO NOT heat it up instead get a peice of tin foil fold it over so its doubled up and put it were the cap was bust a hole in the bottom side notch on the bottle with a knife or something be careful of you will shatter the bottle and put the cannabis on the foil inside the bottle cover the hole you made use a bic to heat it up but not to much then when its full just let go of the hole and breath in it costs less then a light bulb

Noeone

1st thing- I have two vapes, practicality is not really an issue.

2nd thing- Rat shack (radio shack) sells variable temp soldering irons, I have one actually, it's fairly nice but a little pricey (got it on a sale).

3rd thing- I was wondering about the beer bottles and the heat. Wasn't sure what kind of glass they were made out of.

I might put off the cheap one and just work with the labware I have. I can work out the bugs without having to buy/dive extra stuff.

HerrSmokes

haha, Thank you for keeping the facts right! I was wrong, i guess you can get soldering irons with a varible temp! I'll surely have to look into that... When you say "temp" do you mean "high,low, off" or like an arbitrary number?

Beer Bottles are in simple terms a "hard" glass I'm not sure of the actual name, but PYREX is a hard glass we all know. Any glass your pipe, art, and other random things are made of is whats called a "soft", called "soda lime" glass. I'm not a molecular scientist,so i cant tell you what exactly causes it.

Soft glass will melt at a lower temp, and stay soft for longer.
Hard glass melts at a higher temperature, but due to its uses it is often time very thin, so it relative heat threshold compared to your piece(pipe) is a lot lower.
Hard glass is also not as flexible. Heat hard glass and hit it, it will shatter, heat soft glass and hit it.... it will just bend.


Now you mention using the lab ware you own. My guess is that its all PYREX. Thats fine, as a Pyrex beaker/flask/jar, is usually always thicker than a beer bottle. For a high heat application, as some vapes are. I'd prefer a hard glass as long as its thick enough.

Noeone

Full range, even has a display that shows the set temperature.

Yah it's all pyrex and the test tubes are corning brand name (expensive but ever since I got that video of a nitric acid distillation going pop I've been shelling out for good glass).

Anyhow the whole design is changing into a hot air system, just not sure how I want to heat the air (I'm leaning custom heating element so I can toss a temp sensor with the weed to maintain temperature). So the test tube is looking more like this

and the heating element is up in the air (might try to make it self contained so the test tube can just be attached and plugged in)
