Aluminum is not fully transparent to RF but it definitely helps. Remember that there is an RF field along the legs of the coil. Typically you want the design to route the two wires close together. You might be disrupting the field around the two chokes.

@maremaresing - you're problem is that you have a metal box. You are inducing current into the chassis. It also appears you have shortened the coil wire significantly. They are tuned for 3S with the wire being 33" long. You're coil-wire length could be sufficient to try a 2S arrangement.

That mouthpiece isn't working for me esthetically. Too small and a poor blend.

There is such a thing as 'RF-transparency' which determines the interaction between a material and how it reacts to the RF field. This is fairly easy to test. Measure the current with an 'idle' IH and then insert the material in question into the coil and see if the current changes. A good...

This is correct. The cap shields the inductive field.

Watts is watts. Eventually everything will heat up, so the question is, wat rate of heating do you want. 120 watts based on the standard module is nothing to sneeze at. I find 60-70 watts to work out perfectly for a DV. This says you can easily double the mass of the tip/cap and still have a...

My last measurements were of some 419 caps I got a few years ago with the 3rd batch of cap materials. They came in at a GR of 5:1. The '3rd batch' was of the original source. Learned since then that making 304 stainless steel magnetic requires work hardening the material. That means is it...

I think this requires a center-tapped coil @kokolokokolokon since it only has one choke.

@132ikl - Your low power draw may be your cap. The weakest cap I ever had came in at around 2.5 amps on a M'20. Also check the voltage at the input of the module to see you have at least 10V. The way you make the power level a bit higher is to remove a loop from the coil. Of course, winding...

That's disturbing as ebony is one of the toxic species.

Click would take a little longer The click would come a little sooner Number of turns seem to have less effect The multiple layers is simply to use the complete wire length The ingress depth moves the clicker further from the sweet spot. This delays the click allowing more heat to build up...

@highvaper - coil wire impedance can be modified with limitations. If you are staying with the 12 awg magnet wire, it is pretty easy: The stock coil is 33" for 3S operation (12V). The stock coil is 10 turns; This equates to approximately 1V/turn, or 10 watts increase for each turn removed...

My iron is a 20/40 watt RadShack special with a 1/8" chisel tip. Solders 12 gauge coil wire to the plane with ease.

You can tame the heater a little by removing one of the black capacitors. If you want to use a high temp shrink tubing, look for PTFE shrink tubing. This minimizes outgassing.

If their readings surpass 0.3%, they don't except it. The growers are usually the contractors so they have a vested interest in meeting the test requirements. I don't trust growers to deliver top shelf flower. I prefer a reputable reseller. I buy strains so I am limited to who I buy from...

@deadsouthernblake I have purchased a lot of variety packs from reputable resellers. This is a great way to see what different strains taste like and how well they vape. I find that the farms that sell direct are not really targeting consumers like us. My first foray into CBD sucked. I have...

Check out Jaxon [buyoregonhemp.com]. I get my blue dream CBD from them and it is always a good deal.

Hobby King was a bit of a pain. I tried checking out with PayPal and they held my order because something didn't match up. PayPal was charged but the order was put on hold. And, of course, there is no one to contact. I worked with CS, such as it is, and it took over a week to cancel the...

More capacitors should do the trick.

Oh no, @rvarick . I was only saying that LiPo cells are more robust. Li-Ion cells are very touchy about how they are made.
