That is probably the best setup available for a mains powered IH. Variable voltage is the right way to manage power levels. That converter with the remote potentiometer is perfect as it has a 12/24V switch making it harder to over-voltage the IH when you lock it to 12V max output. There is a...

With ya all the way. Those half-bowls tend to be much more consistent and hard hitting.

what @coolbreeze said. Jeff didn't want to run afoul with the law on shipping potentially banned devices.

Jeff wouldn't have minded a temp control challenge but fucking with USPS and ATF was a different story. Juul and others basically won their lobbying pressure campaign and took out arguably the best heater available.

Those unmarked caps are early '18 or earlier. I'm finding a lot of those are pretty decent caps. I only wish I had some THC kief. Mine is mail-order CBG. Pretty decent stuff to help bake more evenly. 'twigs and seeds' we used to say about the waning stash. I have a shitload of sugar stems...

I powdered my flower to get more in the bowl. Then I backfill that with kief. Makes for some heavy draws.

1 and 2 amp versions will work. Be sure your USB wall-wart can handle the higher current. I've pushed my BMS' to about 1.5 amps on the charge side. The 2 amp version will charge at a 1.1 ah rate and draw 2 amps from the USB supply.

No magnetism says it is ti. 2.5:1 gain ratio says titanium is as effective as a weak cap @RustyOldNail Pocket dialing is one thing but pocket ordering just the right thing is a twilight zone phenom. You once asked why some coils are small. You might have it figured out right here. Short...

I have one of those @RustyOldNail - its plated steel. Put a magnet up to it. Also put your Ti tip in the IH without the cap and see what it does. I'll get a gain ratio for ti at some point. Never thought to do so LOL @510vaporent The cap is stainless steel but a different alloy. I don't...

Remember that 'delay' function I talked about? As you put the CV deeper in the coil, you are effectively delaying the click so more heat gets into the cap. Definitely experiment with this but your findings will come to this conclusion. Ingress depth determines the bake at the click - power...

Turning down the voltage at the same ingress will bake it exactly the same, just slower. Make the flat of the cap flush with the bottom of the coil. It won't take you quite as far to the edge. Maybe a 1/16" past the coil will give you a good hard hit. Remember to gauge the second bake, not...

If the coil is 'sprung', you can tie the coils together with some string. It shouldn't get too hot until after you use it a while. DON'T leave it on! Solder is the only guarantee you won't blow the FETs from a transient. That is what makes them robust.

You got a decent cap, as far as induction coupling goes. Also the perfect tip IMHO. My starting point for click level tuning is the bottom of the coil flush with the flat of the cap. Deeper means more delay for heat to reach the clicker. Delay means more induction heat injected into the...

Oh good, no, 10V is often a very good place to land. 60 watts is only 6 amps at 10 volts... Remember that the power supply's inefficiency also has to be accounted for at the wall plug meter. Curiosity question; what cap are you cooking with? Solder that coil to the board as soon as...

Those donut things are inductors, or as we use to call them, chokes. They convert electricity to magnetism and back to electricity again. 60 watts with the vapcap inserted? 10 amps? just checking. 1.5 amps (20 watts) when putting power to the module without the vapcap - may 4-5 amps (50-60...

There is a fairly robust epoxy on the wire that acts as an insulator.

Sorry about the covid DC. Hope you have a speedy recovery. We're still being super cautious on our end.

Typical induction coils for industry do have space in between the wraps. Our tightly wound coils are a matter of putting a lot of copper in a small space. basically, the circuit is tuned to a specific wire gauge at a specific length. In our case, we use 12 gauge at 33" long for 12V operation...
