WesleyPipes Posted March 17, 2008 Share Posted March 17, 2008 (edited) So my friends and I have been very interested in these electric hookahs. Did a little research and we have found the correct way to use electricity to heat the shisha. A nichrome coil, with a temperature adjusting potentiometer, is used to heat the shisha to the perfect temperature.The coil is placed above the shisha, in the same manner as a coal. We havn't mounted this in anything, but I am thinking mounting it in an upside down bowl might be a good idea. This has to be plugged into a 120V electrical outlet. The cord has an on/off indicator and switch.I'll be able to put some pictures up here soon.So far she has been working superb. Your thoughts on the design?

Canon Posted March 17, 2008 Share Posted March 17, 2008 upside down bowl might make it hotter. if it works you have done something many have tried and all have failed Link to comment Share on other sites More sharing options...
WesleyPipes Posted March 17, 2008 Author Share Posted March 17, 2008 Ya, that is true. If that ends up happening you should be able to just turn it down a little.We will see, but she already works pretty solid so the housing would just be for looks.

mj_b90 Posted March 18, 2008 Share Posted March 18, 2008 Once you get those pic's up get some schematics of that up! I wanna make one!! :-D Link to comment Share on other sites More sharing options...
Voski Posted March 18, 2008 Share Posted March 18, 2008 Upside down bowl would make it act as a wind cover which would cause to much heat. Go with no wind cover type thing so you can add heat if its not smoking. Link to comment Share on other sites More sharing options...
WesleyPipes Posted March 19, 2008 Author Share Posted March 19, 2008 (edited) That is true. Right now I'm just having a problem with finding an easy way to mount the coil to the bowl, while still allowing you to pack the bowl easily.Schematics are very simple...but be careful if you're going to try and make once because you can easily shock yourself.To make it, grab an electrical cord from something you don't need anymore. Strip both ends of the non-plug side. Attach one side to the middle lead of your potentiometer. Now attach your nichrome wire to the left lead of your potentiometer and the other side of the nichrome to the unused lead of the electrical cord...you're done.But I did leave a few things out as I'm trying to be a little entrepreneur and sell a few of these things, so be careful if you're going to experiment and send me a PM if you would like to know some more.

Voski Posted March 19, 2008 Share Posted March 19, 2008 I forget what they are called but you use them in chem labs. Its pretty much an elevated ring with 3 legs that you place over a burner so you can boil water and such. Maybe you can modify that so it fits above the bowl. Then you could place the coil on that?.

WesleyPipes Posted March 19, 2008 Author Share Posted March 19, 2008 Once everything works perfectly, I'll tell the interested people the exact parts which were used. This should also be battery capable, allowing you two run it off lithium double a batteries for 9.2 hours in theory, but we will see how it actually works out.

SimplexCoda Posted March 19, 2008 Share Posted March 19, 2008 dude totally interested. are you considering using some sort of a vacum activated switch on it so that when you hit it starts to heat it? Link to comment Share on other sites More sharing options...
WesleyPipes Posted March 19, 2008 Author Share Posted March 19, 2008 Solid idea. We're just gonna leave the coil at 100-150 celsius so it should stay the same heat as a coal. I heard coals heat up as you hit them, but im thinking if you just set the coil to the temperature the coal would heat up to while it's hitting best, you will receive the best hit and there would be no chance of the shisha catching fire.QUOTE (SimplexCoda @ Mar 18 2008, 11:47 PM) <{POST_SNAPBACK}>dude totally interested. are you considering using some sort of a vacum activated switch on it so that when you hit it starts to heat it?

Bulldog_916 Posted March 19, 2008 Share Posted March 19, 2008 Nine hours would be the equivalent of 2-3 smoke sessions for some of us. Hopefully rechargeable will make that easier. Cant wait to see how it turns out. Coal is still cheaper IMO, unless you find a way to plug it in or carry batteries everywhere you go... Link to comment Share on other sites More sharing options...

Guinea_Pig Posted March 22, 2008 Share Posted March 22, 2008 hi, im new here... Just had some thoughts on this as it seems interesting. How about using a computer PSU to run the nichrome wire... i reckon you would need quite a bit of battery to keep it going for a long time and your average PSU will kick out 200W all day long no problem... Another problem with using lithium is risking over discharging them... if they are rechargeable you kill the number of cycles they will hold a decent charge for quite rapidly... if they even take a charge at all after an over discharge... Also a little googling leads me to believe that an AA lithium battery from energiser holds 2.9Ah so to last 9.2 hours the 2.9Ah lets for simplicities sake say 3Ah battery last again for ease 9hrs it would have to be supply a third of its capacity per hour to last the 9 hours... in other words 1A... So what rubbish is this newbie gassing on about? well what im saying is that 3Volts * 1A = 3w... I have had way too many beers so my calculations *may* be completely off.. im trying to remember school lol, in no way am i putting this idea down but i think the power supply is a little unrealistic... um so hello... and dont think im a complete arse based on this post.. cus it was reading this thread that made me sign up in the first place!

austinthecity Posted March 23, 2008 Share Posted March 23, 2008 my additions: (i have no idea how viable they are)put the wire (heating element) inside the top of a tall windcover. people might say this would get too hot, but you could just have it at a lower temp than a normal coal.have a default "plug in" heat of whatever a non-hitting coal itrun a wire along the outside of the hose with a button to toggle the "hitting" temp of a coalthat way, whenever you hit it, you press the button and it simulates a coal.

WesleyPipes Posted March 23, 2008 Author Share Posted March 23, 2008 I'm not sure how a battery pack will actually work since I havn't tried it. Damn Canada shipping won't let my nichrome get here. But..12V/44 ohms = .272A2.6A/.272A = 9.55 hours of battery lifeAnd to hold the coil, I have one of those flip-top bowls on the way. I'm gonna try to mount it in the top and have the coil where a normal coal would sit. So I figured the nichrome would be here already but it's not. When she's here, you guys will get instant pictures of it in action with a little cherry cola tobacco. Link to comment Share on other sites More sharing options...

Plain Old Me Posted March 24, 2008 Share Posted March 24, 2008 I would advise anyone to be extra careful when doing anything here. I just tried out my nichrome stuff again (see my alternative to coal thread) and it again melted, and using light dimmers the only control I was able to achieve really was just about totally off and melting temp. I think pots may be the better way to go in order to control the temp, but be sure that you get some damn high rated pots if you are using a 120v/15w plug. The direct radiation and contact method this guy seems to be using would definitely need less heat than the convection method I am attempting, and with my experiences of melting nichrome I could easily see running a coil off of batteries, though perhaps a 9v battery might be more able to keep the heat goin.

WesleyPipes Posted March 24, 2008 Author Share Posted March 24, 2008 Haha, ya I'm sure 120V to your nichrome wire would make it get way over the desired temperature fast. I'm using a 120VAC - 12VAC transformer with a potentiometer.There is a chart with desired temperatures and the current needed for each guage of nichrome wire.

*HOT&SMOKING* Posted March 24, 2008 Share Posted March 24, 2008 If you have managed this, I would be very interested, because as canon said alot of people have tried and failed.+1 to pics and walk through of how you did it.-H&S Link to comment Share on other sites More sharing options...
WesleyPipes Posted March 24, 2008 Author Share Posted March 24, 2008 As soon as this damn nichrome gets here, I'll have pictures and video of this beast in action.Temperature equilibrium? Ya boy. Link to comment Share on other sites More sharing options...
