Hi all, I just had to share this with someone. I built my first 200W mod with LCD display and full control and all safety features a normal VW has.
200W Mod
- Thread starter WestCoastFog
- Start date
It is not pretty, but I just stuck it in this box to test the heat dissipation and efficiency and to make sure my design will handle 200 W for an extended period. I am waiting on a nice box, switches, surface mount logic level mosfets and oled display.
PS: This mod is Afrikaans so it will say “Batterye is pap” “Kortsluiting” “Oop kring” ………

mosfet irfz44n and pic IC as a cpu
using a irfz44n so it can handle 30V 50A
so the only limet is the battery
this one is from 0.5V TO 14.8V
using it in buck boost mode so it can go up to 30 V and yes i am using it in series 8.4V to 6.5V then it shuts down to spare the batts
most is done in the cpu so it is more code than components
so a version upgrade can push the W up or down
I can see so many possibilities with this, imagine....
Touch screen display
Touch screen display
yes it can be done, but then it will be like my phone pressing all the wrong buttons when i pick it up
Very impressive @WestCoastFog, Like the white on blue 2 x 16 LCD. I assume the switching frequency goes quite high as I can't see the output inductor in the pics, most probably behind the Vero board at the top side?
Ya for the boost, buck I am just using PWM from ic and mosfet
and 2 x 16 will soon be replaced wit a 128x64 OLED
working on a nice lib for it
damn dude that is serious impressive work, gooi a dripper on there and klap us some clouds, with vid 
lol I've got a RSST on it with 0.8 ohm and vaped it at 164 W and it is just to hot to get a long draw
But i will try
dont need to go super low resistance coil, throw a 2 ohm coil in the dripper and just power it with watts
