Ah. Ok.

FWIW, I wouldn’t assume there’s extra space. The batteries will be within 1-2mm of the lid. There isn’t going to be room for them to bounce “out.”

Thank you, @stardustsailor . I mean that sincerely - that advice you just shared is worth a hell of a lot more than two cents. I don't feel that I'm in over my head with this project - there's still time for that, lol - but I'm new to many aspects of this adventure and am constantly being...

Thanks, @ClearBlueLou . I get it now, and I can also imagine a way to make it work. As @Fat Freddy said, This. You folks have given me some things to consider, and now that I'm thinking about it...I have a few thoughts on how I would do this, lol. I'll see what I can do. One question I have...

Thanks, @pxl_jockey ! WRT to @stardustsailor - if you read this thread's first few posts, you'll see that SDS schooled me pretty effectively within minutes of my initial post. :lol: And he was right to. I'm kind of just a dilettante with this stuff, whereas he brings an engineer's knowledge...

OK, thanks for explaining that a bit more. I guess I never considered using/heating the DV that way, so it's good to become aware of another blind spot, lol. I'll mull it over. I think the batteries make a vertical, axial, belt-worn orientation challenging to pull off...but I won't rule it out...

Thanks, @phattpiggie ! “TIL”. Oops. :doh: I’ll fix my earlier answer when I’m back at a computer!

Oh ho! Got it!! :tup: I approve, lol! Thank you!!!! :rockon:

Hi @Fat Freddy . For both devices, the boxes will be oriented so the lids face UP, and the Dynavap is inserted in via a hole in the lid. I'm waiting for the next circuit boards before I build out any more devices, as they will be the final designs or very close to them. I'll definitely post...

Wow, @stardustsailor - a new debounce circuit?! If I may ask, how does this one differ from the previous one? I just ordered the parts and a small run of PCBs for the other circuit on Friday, so I am very curious, lol. In any event, THANK YOU!!! for sharing your innovations with the rest of us...

Hi, Thanks for the great questions, @pxl_jockey ! I'll answer as many as I can at the moment. > Can you please explain how the Mother Fluxer and Flux Deluxe differ? What are their respective use cases? (paraphrasing) That's a very reasonable question. I see these devices this way: The...

Hi, Thanks for the reply. The short answer is that this orientation is a LOT easier to develop, especially for an initial release. Also, tbh, “belt wearable” was not a use case I considered. :shrug: Sorry.

Thanks! If you have a few minutes, there are some updates throughout this thread. The most significant is that the 2x 18650 model in your quote is actually going to be a 3x 18650 in the same size case: The Flux Deluxe. I am waiting on some circuit boards to arrive - it's pretty close. I also...

Hope everyone had a good weekend. A few updates for the curious: Flux Deluxe (3x 18650 IH): I'll be honest, it's been challenging to package the heater and supporting components in a way that safely fit and function inside the 1590B enclosure. I like these sorts of challenges, though, and after...

Thanks! Looking at the data for these four MOSFETs: Ideal MOSFET Spec NTD5C446N NVD5890NL IRLR7843 30N06 1 ) VDS >= 40 V 40V 40V 30V 55V 2 ) ID cont. >= 40 Α 110A 123A 161A 30A 3 ) RDS(on) =< 10mΩ 3.5mΩ 3.7mΩ 3.3mΩ 13.3mΩ 4 ) QGS =< 25 nC 12.2...

Cool! Glad the LR7843 is a good one in your consideration. :tup: I'm very eager to check out the alternative FETs you listed! Thank you for the suggestions! I'm in the US, and a quick check shows I can get the NVD5890NL and NTD5C446NT4G from Mouser and probably others, so I'll give those a try...

Thanks again for sharing all of this information, @stardustsailor ! Two quick, preliminary questions: 1: I've read several of the articles to which you linked, and went looking to buy some IRFBL17N50Ls to play around with. Unfortunately, I can't find them anywhere. The article you linked to is...

Thanks for pointing me to your thread, @stardustsailor, and for accumulating, assembling and especially sharing so much useful IH knowledge! Wow, there is so much here to digest! LOL - this thread truly makes me feel like a dilettante. Thank you! I believe I have some reading ahead of me :brow:

Sorry, I was offline for a bit, and it seems like @stardustsailor has dropped more knowledge while I was away. And now I need to run into a meeting. Tell me more - I'll reply when I have time!

Noted! And thanks!! I was not aware of this issue, but it looks like it will be straightforward to fix. And the device will be much better for it. A genuine thank you, I appreciate the help!
