Spoke too soon on them working.
I put it all together and I have a problem. It fires continuously without pressing the switch...
Checked that switch thinking I had used the wrong two posts but it is correct.
Docked it to a lipo pack 11.8v
Output 3.97v should not be showing if the switch is not pressed. Pot working fine fro 3.3v to 6.04v

The 7.5K resistor is too high for a 12V+ source - so need to replace the 7.5K resistor with a lower ohm resistor to prevent auto-firing. I've replaced the 7.5K with a 4.7K for the 12V source passthru I'm working on.
You want a resistor low enough so not to auto-fire, but not too low that would draw too much current when idle. The 4.7K resistor is also fine for the 8.4V source, so I'm switching to that for future builds.
Try a 4.7K resistor or something in that range BJ and let me know how it works out for you.

I could not figure out my problem. Replaced the 7.5K resistor but that didn't help. Went manual and put a high amp switch direct.
truck has a 20 amp source.

thanks mamu, I figured it was that resistor but I just tried replacing it with a new one same 7.5k thinking first was bad.
It is working fine manual for me so me thinks I will leave it manual... If I find a 4.7k in my stash I will change it in the future. For now I want to see if the raptor will hold up wit any voltage peaks in the truck.Good to hear it's aok now. Love the big clicky button!
I got surprised too by the auto-firing when I was tinkering with the 12V source for my passthru mod. The Raptor datasheet calls for the 7.5K, but the 4.7K is doing aok for me with no auto-firing with the 12V source, but it's still all on the breadboard.
The hold back for me for getting my passthru done is finding a high amp male and female DC jack. What's readily available are only 3A rated and I don't want to use a barrel connector. Finally found 11A dc male and female jacks made by Switchcraft that I got yesterday, but that seems as high as they go. Is good for me though since I only pull around 5 amps under load anyway so I have some current cushion with the 11A jacks if I want to vape higher amps.

looks nice bj !
just thinking out loud....its been a long time since I played with voltage regulator ic s ...mabe the in out difference would have to be bigger ? would that help with voltage spikes from your cars system ?
also just wondering how much current an rca connecter is good for ?

they are rated 24v 3amp so most of my vaping is around 5 volt and less than 5 amps. I will be getting some of the 24v 11amp that mamu found.
My 5 and 6 amp ac/dc 12v power sources use this plug.

Just an update to inform, have been using this in my truck and the raptor seems to handle any voltage peaks over 14v fine.
Imput v was only displaying when fired. Wire to slide switch was connected to wrong side of fire switch. Corrected.
4.2v on a 1 ohm
12.4v from a 12v 6amp brick 11.9v loaded...

On the ECD meter.
cur 3.72 amps
Batt v 4.15 v
Res 1.03 ohms
Power 15.5 watts
Sure wish someone would come up with a new ECD for higher amps. Come on guys.

We could mod that Turnigy 7 in 1 checker and add 510 battery and atomizer connectors.
I'm going to get one and do it... another toy to play with.
Thanks bap!!
Only problem is that it needs a secondary 2S to 6S power source. A 9v battery works, you just have to give positive voltage on two of the balance connector pins.
Somewhere I have some pics......will find and add
