hi @polykoma Thanks to you and many others for sharing your enthusiasm for this project and sorry all for an overdue update. I'm still working on this VC IH. I've made great progress on the modularization redesign. My main three objectives above have been accomplished I built up a board from the first modularized design and got everything working after a little modifications and have a few minor things fixed for next PCB cycle already. I have to figure out how to ramp up production of these as the hardware is getting to a satisfactory point. I still haven't done any enclosure work. I'd love to work with select few makers in the community and eventually provide them with a few boards to dress up. I don't think I'd offer completely blank boards as a kit unless you're very confident with SMD components like QFP-48 and can deal without any documentation (yet). I'd prefer to offer assembled devices without enclosures as I can at least make sure they work out the door. There are a lot of parts that need to work right for it all to come together properly. I've been eyeing those addressable RGB LEDs just like in that awesome looking Dr Dabber vape @Hogni I don't think end users really need the OLED so there are things I need to simplify before larger production runs. I'm mostly doing this as a hobby but it's costing a hell of a lot to develop so I have to recover somehow and I really love this tech so I have been involved with other projects which will bring IH to the ppl quicker but for feedback controlled vapcap IH you're all going to have to hold on a little longer Stay tuned!
