Cleaned my daily drivers, ordered 18M+Ti tip + 18M+M(faf). Yummy Dyna weekend to y'all! :)

Yes.. almost :) However, The organic material inside is COMPLETELY unscathed by the electromagnetic waves swooshing back and fourth through it. This ' microwave' mostly just heats metals, and more so, metals that are in a loop! Like the circumference of the VC tip, where electrons can whizz...

I experimented a little with a piezo electric sensor. Hooked up to an oscilloscope, I could easily see a click, so I'm sure it would be possible to interface properly with a microcontroller. However, the click is an indicator that requires interpretation. It varies a lot depending on initial...

Good luck @RastaBuddhaTao. U know where to find us:tup:I'm keeping some DC converters in my mouser cart anyway. Interesting stuff.

@szai I have considered it, it makes some things a bit easier like not having a weird perpendicular mounting mechanism for the sensor and LED string. It doesnt fair too well with thickness though. The sensor is about 1cm tall, and the coil is just under 2cm long, with a little space between...

So that feeling after moving all the furniture around, then coming up with a (possibly) better way, so moving it around again. Some things we just don't see until we get a chance to sit in the wrong place. So I'm moving it all around again, but I'll eventually find a good arrangement :) I'm...

What issues are you having with your build? Any idea what caused it? In these circuits, it's usually the transistors that go.. DZ1 is a zener diode. It's function is to limit the voltage applied to the gate of the transistors. The gate of theses transistors would get damaged if driven above...

@DataRocks Here is a the circuit which should be pretty much what you have on the little board you're using: from: http://kaizerpowerelectronics.dk/general-electronics/royer-induction-heate I don't want to just go off about capacitors half full of electrons, so to keep this post somewhat...

@DataRocks looks like a beefy supply! What're the specs? What is the gasket on the other side of the wood made of? I'm glad you have a tact switch in there as this circuit definitely needs to be normally off. How many amps is it pulling? As a future upgrade, you can try get a tact switch under...

@Dan Morrison That part reminds me of ceramic tube sockets used in amplifiers. I wonder if you could find one that could be used for the job.. http://theaudiocrafts.com/diy-tube-amps/tube-sockets

Maybe. Specially with single battery mods with slower charging and the only way to get going again is to be prepared with some fresh ones. My guess is that a good 2x ~3000mAH will last most people a few days and almost everyone at least a day. USB chargers are everywhere already, and with a...

Not even with a designated 2S charger with relevant current limitations and an NTC for thermal throttling? built in balance charging? I'm not sure if there are other reasons not to.. ? I've found that 2S batteries stay pretty close even after a bunch of charges. I'd say with a decent pair of...

@oddjobold Battery and heater wiring looks good. The wire from just above B- (where a GND post is on the board) to the GND on the top left is not really necessary as these points are connected internally on the board. These DNA boards look pretty cool. They have a load of useful features...

@Boden load is connected between batt+ and earth. Earth is essentially the batt-, unless the BMS disconnects it.

I'm all for a PMV and costs can definitely be cut on control and feedback features though preferably not on safety. Fortunately, it may not cost too much to be safe :) The BMS design above's BOM would be ~5$. They can also be found pre-built for a few $ on ebay/etc. and come in a variety of...

@RastaBuddhaTao Thanks! I'm looking forward to playing with those! :) I plan to experiment with controlling power delivery to the resistive load. I also want to test how it behaves with the battery protection circuit I'm currently using. Since this project is still open-ended, I'm not sure if...

Interesting indeed. I'd love to play around with some of the heater parts, but I cannot commit to any resulting builds and testing in any specific time frame. I've also got zero experience with these kind of vapes, so I'd have less to contribute there. I don't have any specific design in mind...

I haven't got much wood working skill/tools. I've got a trusty rotary tool though not enough for proper tooling of a case. I can however experiment with electronics, and will gladly contribute chunks of what I've designed so far on my project and have someone else work on casing etc. I've got...

I really need to zzz and then I find this page :science::freak: Kudo's to all involved so far. I've participated in beta builds back in head-fi days and love this spirit so this is sounding like fun. I like the model this project is taking on. I'm busy DIYing my own project and the whole...

@KeroZen looks like good chips indeed though I'm not sure ideal for fast switching IH at logic level. I've played with some logic level MOSFETs for IH and lost plenty of them down at 5~7 volts probably due to slower switching and lockup. I think low gate capacitance and large gate resistor...
