APV Electronics

Right, so I'm a fairly new user here, and I've got an awful addiction to electronics. The whole world of PV electronics interests me a lot. What I've found quite interesting recently is a lot of the conversation around the Provari&DNA20/800Hz vs 33Hz chips in a lot of the Chinese mods. Is there any info on the chips the Provari or the DNA20 use? 800Hz seems fast compared to 33, but both are quite tame in comparison to what can be achieved with a £2 microcontroller. I do realise there's a lot more to the boards than just the PWM, but there seems to be a lot of misinformation and audiophile style hype around certain devices.

I suppose eventually (when I get the time) I'd like to build my own controller board, and there's a good chance I'll open source it when I do, so I'm kinda looking for anyone who's looked into this before, or who has a Provari and a desire to pull apart £160 worth of kit.

You could spend £160, pull it apart & clone it or build another one based on it. If it's a success you might make your money back.

I like you're idea of an open source circuit.

I liked the "audiophile" association.When I was younger,we had an electronics retailer in the town & I would spend hours within his "try before you buy" area,in which was a large assortment of various audio systems & a large bank of switches so you could attach any speaker set to any of the systems on display.I eventually decided that God had only given me 2 ears so there was little point in buying a setup that had dozens of speakers,although I did appreciate the thinking that each speaker could be set to deliver a particular audio range.More recently I bought a 5.1 system for my PC & confirmed my suspicions that no matter what system I used,the acoustics of a room mean that a nice sound could be created in ONE spot(aimed at my ears sat here on the PC)but if I go to any other seat,the audio changes and loses some of the quality.

When vaping,there are so many other variables that change the resulting vapour that it would be difficult to define the PWM as the cause.That said,I'd love to know how to build the controller board so I could experiment especially if it could be incorporated into a device unrestricted in its sub-ohming ability(eg:could power a quad coiled 0.2 ohm device without melting itself through the case as it got so hot)

I actually don't know how to do it but if someone made a pcb kit i could solder it. I've done a few simple synthesizers although they were not smt based micro component. More old school analogue style, standard resistors & caps etc..
