New to the forum and still finding the lay of the land here. Been enjoying some of the topics, especially the free energy ones lol.
So.. Vaping.. also always the focus of much debate. I fear some may steer clear of this discussion in leu of this though I do hope not.
In my view its the best smoking cessation device ever conceived and is capible of saving millions of lives world wide so I'll handle any criticism/questions that might arise.
I've been a vaper for some time, I'm also a fabricator and keen tinkerer. Of course that meant I had to make my own. I've completed a few projects now, some using mosfet switch, various pwm, naos raptor and oklt20 chips, alone and in parallel.
Making these opened up various other possible applications, the first was pyrography. While making a wooden box to house the circuit I decided to decorate it using various branding and carving techniques. Shortly after I added a motor, torch, soldering iron application etc etc. It soon became a handheld power bank with multiple attachments.
I now have several unfinished projects floating around. Seems once I have an idea I soon find a better way of doing it. Most annoying!
I'm here to ask the help of forum in deciding a 'best solution' circuit that will fit all my projects.
Ideally I need an smps system, though I've found some of my applications have very low resistance, this means massive current drains, in some cases they've been over 200A! Way beyond the capibilities of any available smps chip I've seen. Luckily by that point I'd surpassed using Li-ion cells and I'm now using very capible 1s and 2s lipo li-hv batteries. Pwm works quite well, especially 10-25khz, but it's not suited to every application unless I can make it an analogue output, but a 200A rc filter??. Linear regulation works very well indeed, but I cannot use big enough heatsinks in my boxes and the losses hence have a huge impact on battery life, so in retrospect it doesn't work at all.
If any of you have very high current, pretty low voltage (4.2 & 8.4v) variable voltage/current circuit ideas I'd be very open to seeing and considering using them. Or maybr you know of a system containing something I can use? The criteria is for them to be as small as possible, handle massive current, generate least heat and be as efficient as possible..
So basically, all I need is the holy grail, nothing much. lol
Looking forward to the discussions.
