DIY magic flight box help

Discussion in 'Vaporizers' started by happyhuman528, Jan 15, 2014.

  1. So I've been trying to make my own magic flight box but it hasn't been working out right. For some reason the mesh isn't hearing up like it's supposed to. I have a 2500 mA NiMH battery, what I'm pretty sure is a copper wire, and a mesh that I cut from a kitchen strainer. I don't know why is not working correctly. I'm wondering if the kitchen strainer is the wrong material or if the copper wires are too thin. Do any of you guys know what might be wrong or how I might figure it out?

  2. No one's got any ideas? Or have I posted this on the wrong section of the forum? Sent from my HTC6500LVW using Grasscity Forum mobile app

    You posted in the Vaporizers section. I suggest the Toking Tools Q&A for this. You might get some helpful answers there.
  4. Ahh I see. Perfect thank you Sent from my HTC6500LVW using Grasscity Forum mobile app

  6. your problem is a lack of basic engineering knowledge...
    you are not making a pipe or bong with cardboard tubes and tinfoil, you are using known electrical properties/rules/laws and materials that have known electrical resistances/abilities...DO THE MATH!
    you want me to do that for you then pay me..
  7. Thanks cball. You are enormously helpful. Thanks to you pointing out my incompetence, I've decided to pay you the modest sum of 50 dollars to share your wonderful knowledge with a scrub like me. I hope this is enough for an artisan such as yourself

    Schematics, bro.
    From what it looks like, you're pushing a battery against what you hope is copper wire in the hopes that the wire will conduct in what appears to be NOT a circuit in the hopes that the wires resistance will allow it to heat up and then heat up the mesh(Or I guess, have the mesh be resistant/heat?)?

    I don't know much about electrical engineering, but as Cball said this is nothing like a 'homemade bong'. Is the circuit closed (does the mesh conduct?)? Does ANYTHING heat up?
    Idea's? Go back and take electricity and magnetism. Or, plan to take that class in the future.
  9. The circuit goes as follows. Negative end of battery to curly end of first wire to mesh to other wire to positive end of battery. I figured out my previous problem was simply a dead battery. XD I used thick copper wires because that has low resistance. The thin mesh should have high resistance which would cause it to heat up, thus vaporizing whatever plant matter happens to be in the mesh trench. The issue is, I think, that either the mesh is not actually stainless steel, or that the copper isn't thick enough or is too long. The screen is heading up too slowly right now. Nothing like the real mflb. Sent from my HTC6500LVW using Grasscity Forum mobile app
    Now we have something to work with! Your circuit works, which was my main suspicion (that it wasn't) so, moving on!
    Troubleshooting: energy flow
    Do your copper wires get hot at the same speed as the mesh? Could be not enough current is reaching your mesh (I don't think this is it, but lets hit every aspect!)
    Hook your DIY MFLB to a stronger power source. See what happens. Could it be your new battery is still too weak to power this?
    The coppers thickness/length wouldn't have anything to do with it. They should be thick enough to conduct the electrons to the mesh with minimal resistance - they look thick enough. Length ought not matter too much here.
    Sounds like your mesh is what's messing you up. Cball has said that all these materials have properties; look them up and do some rough calculations to determine resistivity and what ought to happen. Instead of cannibalizing materials from around the house, buy some of KNOWN composition for projects. Remember, you need this to be a certain temp! You dont just want to heat the wire up until you turn off the system.
    Also, go here.
  11. Thanks that's really helpful! I'm going to go out right now and try to get the right kind of mesh at the hardware store. I'm going to start with a new piece of wood too. I found a better design. Once I try with a stainless steel mesh (highish resistance) I'll let you know how it works! Sent from my HTC6500LVW using Grasscity Forum mobile app
  12. Okay so the hardware shop was closed so that will have to wait until tomorrow. But I'm wondering what this kitchen strainer could possibly be made out of If not stainless steel.. Sent from my HTC6500LVW using Grasscity Forum mobile app

    Be careful with that contraption
