Thousands of mods out there. Some can be really small, but yea.... I'm a more power type guy. The smallest most capable mod I have is the Target Mini (these will only handle the resistance of the Muad Dib though the mflb is lower resistance than this one will handle)

With diy you can only go so far really. When I start making stuff for sale will definitely keep pocket friendly in mind. The cost for going beyond a simple power adapter would be more though, especially given I would have to work with electronics and such. Here is a sample of something I had in mind with a battery on the side and chip on the bottom. These would be CNC machined too so quality will not be matched. I would give time estimate on a simple power adapter 6-8 months and beyond that just touching a year (corona will probably screw with these estimates though) Sorry, I hate taking so long but, these will be made by me personally so, I need to setup the gear to be able to make these.

Also, I made a second video around the time I made the first one. The first video was more of a demonstration of the short pulls you can take the second is on more tame settings (350f temp control 40w max) I had to vape through the moisture on the herb so the couple first seconds of the video may be underwhelming but, if you wait through, you can definitely see the potential. especially given that I could do 800 pulls off a charge.

You can really abuse it a lot without worrying about ever going over set temp more then 10f. The whole pull would be around +-10f in fact.
Edit: for those interested in diy, please keep in mind temp control relies on accurate ohm readings. I can't comment on how well a diy will do on temp control as the mflb in general does not focus on tight connections. On wattage mode the mod will always adjust to the (maybe poor connections by upping the volts) So you "should" be good.
