Raptor coil build/test mod...

[mamu]

This project was the request of a friend (dancing disco Dino ) who does a lot of coil building and testing.

I used a Hammond 1590YBK case (92mm x 92mm x 42mm).

Features:
-Raptor 20A 120W
-Output voltage: 3.3v - 6v
-Reverse polarity protection via externally added p-channel mosfet
-Input overcurrent protection via externally added PTC fuses
-6v (loaded) low voltage cutoff via externally added zener diode
-Power connect/disconnect switch
-Volt/ohm meter power connect/disconnect switch
-LED power on indicator
-LED low battery indicator

Dino needed an ohm meter that it is accurate, reads less than 1 ohm, and reads ohms to the hundredths. I initially was going to use a separate volt meter and ohm meter, but then went on a search to find a combo volt/ohm meter that would meet the requirements I needed. I ended up using eleaf's combo volt/ohm meter and am powering it with a 4v 250mA LDO.

Beautiful rig mamu!!! I absolutely love the concept of it. And the look of it is so clean! !

This was my next project very cool. I was going to use a cheap 5v step up board for power and a ldo for the meter. I never thought of using a Raptor, I finished my 10a raptor 3 weeks ago so it would be easy to use one for this purpose and they are so affordable. Thank you for the information, I will probably have a question or two in a few days lol.

Not sure if I like it yet prolly cause I love it. Except the part about made for that Dino guy. haha when's mine..
I have two beanie babies and an old comb that Elvis may have looked at for trade.


very nice testing rig Mamu..

Hope he shares the ultimate coil he finds

Buddy of mine Rolf built this http://www.e-cigarette-forum.com/forum/modding-forum/608273-coil-winder-tester.html if you wanted to get real creative you could incorporate all of this together and have a coiler and high power test station.

Nice

Mamu would you happen to have a diagram of this build.

Just insert the eleaf volt/ohm meter wiring into the circuit similar as you would for a standard volt meter, except you need a separate low volt power source (you can use 2x AA batts or the 4v LDO like I did).

I used a DPST switch to power on/off the volt/ohm meter instead of a SPST switch so to match the power connect/disconnect switch. I also used the LTC1440 comparator as a low input voltage indicator set to activate the red LED at 6.2v.

Thank you very much. I have a eleaf ohm meter that I am going to remove the board from and maybe shorten the width to use the sled for the two AA batts. Is there somewhere to buy the meters by them self for future use. I quite like them they are very small and seem accurate.

Nice job Mamu! I made something similar to this about 2 years ago but this makes mine look primitive at best.

Put these into production and I believe sales would be insane. Do you ever make anything for sale?
