Ni200 coil calculator

Can produce.....and use whatever wattage is required to achieve the desired Temp setting.Now if you want big clouds from TC..... you probably won't get there using a factory made coil head.... as TC is more about flavor and consistency than big clouds. Gonna take some building trial and error to get super big clouds from the tank using TC. Clouds are about maximizing power usage. TC really more about minimizing power.Sent from my SCH-I605 using Tapatalk #5 Many thanks for your answers, guys. I understand now! #6 Use boost or punch preheat to ramp up faster and then tc holds the temp to keep your coil at the temp you set. If 500 seems comfortable and you dial in watts to get there it will level at the set temp and only apply enough power to maintain that set point.Sent from my iPhone using Tapatalk Just Frank Platinum ContributorMember For 5 Years #7 I don't understand why a bunch of the tanks from yesteryear used nickel coils. I mean if a person didn't know any better they would just use it in wattage mode. I have tanks that have Ni200 coils and I haven't put one in. They're like garbage to me because I don't trust nickel. Am I being too cautious and missing out by not using them nickel coils? #8 Not sure Frank. I believe there are a few ppl that are allergic to nickel so it fell from favor. Also the nickel is softer and doesn’t hold up as well. I don’t believe you’re missing something huge though.Sent from my iPhone using Tapatalk #9 I don't understand why a bunch of the tanks from yesteryear used nickel coils.

Am I being too cautious and missing out by not using them nickel coils? Simple early TC devices couldn't regulate other wires.... harder to regulate wire with resistance like SS. SO TC STARTED with Ni200. Then Ti.... then just recently SS...NI200 is safe enough if you dont get it hotter than about 800 degrees.. or red hot. Only time those temps are approached is when dry burning.Sent from my SCH-I605 using Tapatalk

#1 Hi there,Usually I vape on ijoy 5s RDTA tanks (love them) but now I decided to try temperature control for the first time with my uwell crown and a Ni200 0.15 ohm coil. I am using a tesla 200W WYE mod (had issues with it, would not recommend it). The thing is I don't understand well how all this T control thing work. If I am setting a given temperature, why would I modify the wattage? (not good at Physics). My other question is that I read most people use 50-70W and 400-500ºF but I tried that and found it too cool, with only modest clouds, not a warm vape as I am used to. Should I go to higher temperatures or is that risky? Should I increase the wattage? That seemed to make no effectThanks!Federico MrMeowgi The Vapin' Drummer VU DonatorDiamond ContributorMember For 4 Years #2 I used those same coils in a crown tank years ago. The wattage is the ramp up of how fast you get to the desired temp. I ran about 40 watts and 500°..Sent from my LM-Q610(FGN) using Tapatalk #3 Hi there,Usually I vape on ijoy 5s RDTA tanks (love them) but now I decided to try temperature control for the first time with my uwell crown and a Ni200 0.15 ohm coil.

If you like warm vape with tons of clouds TC ain't going to do it for you .... If you have to vape at 500 degrees and 80 watts on Temperature Control and still not hot enough then stay on wattage power mode..... Get a Yihi..... Amazing TC.... Sent from my Pixel 2 XL using Tapatalk #4 As long as you keep the coil wet... you can vape at any temp the mod

Emphasis will be for short coils where the lumped circuit approximations fare best. When building an antenna trap, self capacitance can be a very good thing to cultivate, since the self resonant point can can be produced with lower inductance (and wire length) when in resonance with more coil self capacitance. To begin with, lets look at the arithmetic for single layer coils. Single layer coils have the advantage that they are well studied and hence we have the best chance that we can come up with a way to design them accurately for our needs.Single layer coilsWe start with an expression for the inductance of a coil using the current sheet approximation and corrections for magnetic fringing fields.[1] Where is called Nagaoka’s coefficient which is a well tabulated function of the coil aspect ratio. D is the winding diameter, N is the number of turns, and l is the length of the coil. We can express the wire length of the coil as[2] in terms of the number of turns and the winding diameter. Rearranging we can express the inductance compared to the coil wire length as[3] where is the pitch angle of the winding. For close spaced windings, the cosine term will be very close to one.If we call the spacing of the windings, then the number of turns will be[4] where is the coil length.We use Knight’s formula for capacitance.[5] where[6] and is the permittivity of the interior coil former, and is the permittivity of the exterior environment of the coil.For the purpose of building trap coils we are interested in the resonance condition for a particular wavelength . Resonance will occur for a set of inductance and capacitance values that satisfy:[7] Now we can substitute equations [3] and [5] into [7] to obtain the following expression:[8] With a little rearrangement and cancellation we arrive at[9] This shows explicitly the basic dependence for a resonant length of wire modified by a “geometry term” that depends on the shape factor of the coil, and the dielectric constant in and around the coil.Spreadsheet Trap CalculatorThe user will specify the resonant frequency, the winding spacing, and the dielectric properties. From equation [9] we can generate a set of coil geometries, and , that will satisfy the resonance condition. The spread sheet then calculates the rest of the specific parameters for the set of coils. The self-resonant coil calculator spreadsheet can be found here.Example output of the calculator is shown above. Most commonly, you would pick the frequency of the trap, knowing your wire size you can set the wire spacing for a close-wound coil, and then choose a geometry based on that meets your other requirements (e.g., the winding form diameter you have on hand).Dealing with Dielectric Coating on WiresKnight does not include any corrections for dielectric wire coating. However, his expression for coil capacitance does include which is the external dielectric constant, nominally 1.0 for air coils. This is a handy “fudge factor” that we can use to achieve

Little more difficult because there can be higher harmonic resonances that make assignment less reliable, but combined with the low frequency inductance and the self-resonant frequency, an equivalent parallel capacitance can be calculated. Since we know the coil geometry and its self-resonant frequency, we can use the spreadsheet calculator and see if we get agreement. The one unknown for the calculator is what to use for . Hence, we can vary so that the calculated results best match the experimental results. The data for several coils is shown in the table below along with the required fitting parameter.CoilDescription 𝜖jckt𝜖x best coil Dia. (mm)coil Len.

At resonance, the coil has about 24 kΩ resistance with a modest bandwidth that would allow such a coil to be effectively used as a trap for a typical ham band. The measurements give good guidance for the value for needed for the coil calculator spread sheet. Using somewhere near 60% to 80% of the jacket dielectric constant seems appropriate for coaxial cable. With the test coils on the bench there were a couple of other questions to explore. I want to understand how a hard rain would effect the performance of the coils as traps, so I soaked the coils with as much water as they could hang on to, simulating a rain-soaked operation, and measured them again. I also wanted to know what would happen if I wound the coils on a layer of aluminum foil to enhance the capacitance. A summary of the four measurements for each coil configuration is shown below.CoilDescription𝜖jcktf_sr Dry (MHz)f_sr Wet (MHz)𝜖_xdry𝜖_xwetf_wet / f_dryf_sr Foil Dry (MHz)f_sr Foil Wet (MHz)Foil f_wet / f_dryR_mx Dry (Ohms)R_mx Wet (Ohms)R_mx Foil Dry (Ohms)R_mx Foil Wet (Ohms)Q Dryf_sr_Foil / f_sr_NrmlAPE-RG11 on PE bucket2.39.158.721.92.20.9534.964.740.95637500375003730018700330.54BPVC-RG6 on PE pot form~418.9218.172.352.600.96011.3611.000.968152001580080907100170.60CPVC-RG6 on PVC pipe form~422.621.422.63.000.94812.9912.260.944173501310085007100180.56D#14THHN on PVC form~412.8612.381.922.130.9635.425.010.924190000919002290014300750.42These measurements allow us to make a few observations. First, water wicked on the coils lowers the self resonant frequency about 5%. This could cause some de-tuning in the rain, but could probably be mitigated just by choosing the “dry” resonance a little on the high side. Which brings us to the second point; at resonance the real part of the complex impedance can be large, typical 20 kΩ or more. It is know than polyethylene has a much lower loss tangent than PVC insulation. That may be part of the reason why the large coil made from the PE-jacketed RG-11 had higher resonant impedance than the PVC-jacketed RG-6 coils. All of the coils tested have a large enough 5 kΩ bandwidth to cover the typical ham band. Winding the turns over a sheet of aluminum foil generates substantially more self capacitance so that much shorter conductors with lower inductance can be
