I am not sure if this was sorted but here's Mamu's quotes on that...
Alright guys, having trouble with one f these. I am building one for a friend, and I have built ~10 previously.All wired up, fires for a second and then sort of crackles. It'll turn on and off and crackle in between.I tested for V starve. When fired it drops to 7.9 but that should be fine.It's got me scratching my head because I have built around 10 this exact same way.Help me out?
got 2 for testing from a shop interested in my work...Something pretty coming soon...
after looking at schematic does the 2 caps wire in series to pin 4 & 7 (counting from left) or paralell to 4 & 7? and if this is for myself there would be no need for p-fet and led correct just wire in fuse protection.**edit**I think I found answer in page 1 to wire in paralell...my other question considering min input is 4.5 it can only be powered by 2-18650' in series for 7.4 or will it work in parallel @3.7 has anyone wired it that way to see if it fires
Yes - caps and fuses are in parallel.The Raptor is a buck converter - needs a higher input voltage to step down the output voltage. Buck converters require ~ 1v (it varies depending on the converter some require as much as 2v or so) higher input to output - meaning output needs to be around 1v less than input.No one vapes at <3v, so 3.7v input is not feasible, plus you're not going to get 4.5v (min input for the Raptor) from an 18650 batt.
S: VinD: Batt +G: Batt -1. This is a teeny tiny smd part and needs mounted. I used a 3x4 piece of veroboard and removed areas of copper as shown below...
what did you use to remove the copper of the strip the board tired a razor blade and its a bit ineffective also i got these caps http://www.digikey.com/product-detail/en/CL31B226KPHNNNE/1276-2769-1-ND/3890855and was wondering how i would parallel these tiny smd type caps would it be the same method as the pfet
so for the pot I see its wired with 2 wires only....trim- & trim+, so trim- goes to wiper and trim+ goes to one of the outer legs or do I have this wrong. I cant figure out why chip wont turn on. reason I ask is most pots are wired with a ground correct .
Thanks mamu. This thing is awesome! Tough build. Took about 6 hrs.
Mamu, yes far left pin#9 is connected to wiper trim pos to outer leg of pot. Switch is reading continuity also. There is just something preventing module from turning on. I have 3 raptors and did it to 2 of then which came right from GE. 3rd(digikey) caps are storing energy also. It has to be somewhere in the on/off remote. Cut it should still turn on even if pot is not connected correct?
So here it is..lots of sweat, blood & tears. But she's a vapin. Turns out sleds were bad not allowing full voltage thru. Thanx for all the support..what a powerful mod. 6v very hot...lol not gonna use at full output. 4.5v is good enuff.
