I want to make a vaporizer without al light bulb because i've heard of a lot of negative feedback about the light bulb and I don't even want to waste my time with it. I want it to be cheap and fairly easy to get the parts for it.
There has been a number of vapourisers for room "freshening" made using common carbon resistors of 1/2 or 1W dissipation, supplied by mains power.
At the other end of the scale, I was working for a company that built vapourisers for asthmatics. The "element" in them was just 2 stainless steel electrodes, connected to mains power. Of course, the insulation had to be good!
Really, how to build a vapouriser depends on how much heat you require.
The method of heating does not have to be electricity.
Go to buy a resistor at 1000 ohms 25 watts. Feed 120 volts AC directly to this resistor. It shall give you 15 watts heat power. Tie this resistor to an aluminum case to expand the heating area.
in a large pot get some water boiling with the lid on. bring to a rapid boil then add a few table spoons on vapor rub reduce heat crack over lid to keep water at a consitent boil yet allow plenty of steam to escape. set up a cott in the kitchen and close the room off if you can. stay there for the duration of the steaming mixture, try not to fall asleep with a fire on the stove, make sure your smoke detector is good and the stove vent hood is off. I'm assuming your not feeling well but other reasons would be that the air is dry causing nose irritation, chapped lips and so on...again assuming! this will help, also a healthy collection of tropical house plants and watered everyday will help keep the humidity up in your home as well. If using a gas stove you will need fresh air ventalation.and remember dont fall asleep. hope this helps.
- VaporGenie . a hand held pipe with a method of indirect heating. Easy to carry, cheap to own. check your local headstore.
buy a big glass bowl and a heat gun at Harborfreight.com . or any heat gun for shrinking tubing or removing paint. Unfortunately they are not as good as a real vaporizer, because they're made out of plastic and have metal heating elements. But they'll do ok. Big hits.
Use a magnifying glass on a sunny day, adjust distance to bowl, try not to burn.
Use a glass bat and heat it lightly from outside the glass, try not to burn the material inside, because that's smoking, not vaporizing.
