Displays input voltage, output voltage, ohms, amps, and batt charge level. Just need to get it in a Raptor 20A mod now. woot! :laugh:

The build is the same for the three versions with electronics down the center and dual 18650 batts, just a bit of a design difference... Avani v1 design - black buttons, 3D printed bezel, maroon Hammond 1550P, have also done this version with 3D printed case using CopperFill Avani v2 design -...

This project was the request of a friend (dancing disco Dino :laugh:) 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...

Features: 16A, 88W Input: 4.5 - 14V Output: 0.69 - 5.5V Adjustable UVLO 2 versions - PTH08T220W and PTH08T221W. I chose to work with PTH08T221W (ceramic cap version). Datasheet here: PTH08T221W Tiny profile for a 16A module (23mm x 20mm x 9mm)... Size comparison with the OKR-T10...

For this project, I used Hammond 1455D801BU (80mm x 45mm x 25mm) and modded the Omnitester's volt-ohm meter and circuitry to fit inside the case. Source input to power the volt-ohm meter can't be done with using an 8.4v source or a 12v power supply - the higher volts will fry the circuitry...

Got the OKL2-T/20-W12 in yesterday and got it breadboarded this morning. So far, so good with testing (i.e., it's doing what it's suppose to :laugh: ). Size comparison with the Naos Raptor 20A 120W board... Min output voltage (I'm using a 1K ohm POT + 1.43K ohm resister - for a lower min...

I found a few AC to DC power supplies that are suitable for use with a DNA passthru mod I'm working on. RS-75-3.3 is 0-15A, 3.3v (adjustable from 3.0v - 3.6v mine adjusted up to 3.7v). Input voltage drop 0.23v running the DNA at 30W: HSP-150-3.8 is 0-30A, 3.8v (adjustable from 3.4v - 4.2v...

Anyone put one of these in a mod yet? Looks like it needs a separate low volt power source or a 3v LDO to power it if using in a buck converter. Parameter of Digital Ohmmeter & Voltmeter: Range for tested resistance: 0.01 ohm to 9.99 ohm Range for tested voltage: 0.01 V to 9.99 V...

I've been wanting to do this project for a while and kept putting if off because of the time involved with stopping the build to take pics and take notes then gather the pics and notes and then make sense of it all when writing the tutorial. But it's been calling my name so I gave up and...

I bought a 3x 18650 (89mm x 58mm x 21mm) DIY aluminum power bank kit a while back and converted it into a dual 18650 DNA30 mod. After doing the build, I have a few do-overs with the next build: I used the ss 510 connector from fatdaddyvapes and although I really like it, it was a pita to...

aah yes fuses :laugh: With seeing quite a few questions and posts here and there about fuses thought I'd start a reference thread for modders to get help in understanding fuses as well as how to choose an appropriate fuse for the converter you've chosen to work with. Some of my knowledge is...

Or maybe I should call it Yinyang. :laugh: Infinity DNA30 has 2x LG 18650 30A 2500mAh batts in parallel for a total of 5000mAh 60A plus 2x 5A fuses in parallel wired to each batt. 74mm x 50mm x 22mm (2.91" x 1.97" x 0.87") Maybe a bit top heavy with a Kayfun lol...

Been testing this DNA30 off and on for the last few weeks and so far so good. I love the new watts lock feature! :toast: With the range of 7W to 30W, I got 0.1 - 0.2 voltage difference from what the DNA display showed to what the watts meter showed with the watts meter displaying the lower...

ok... I worked up the nerve to test reverse polarity with the DNA using just an external fuse without a FET in line. It took me a while thinking about if I really wanted to try this though. I was thinking 40 bucks down the clinker for a DNA if it doesn't work out. Adding an external fuse...

Features: Naos Raptor 20A, 120W dc/dc converter output voltage range 3.3v to 6v external 18A fuse external zener diode for low voltage cutoff of 6v external 2x22uF input capacitors dual 18650 batts This Raptor mod definitely has become my fave mod since getting it done last week - most power...

Aluminum case 3.54" x 1.25" x 1.25" (90mm x 32mm x 32mm). Cricket has 2, 1200mAh 15A round nano-tech lipos for a total of 2400mAh, 36A. I used the transparent material for the display frame/cradle. This is it - I'm hanging up my soldering iron and taking a looooong break from modding...

Aluminum case 3.15" x 1.77" x .74" (80mm x 44mm x 19mm). The 19mm depth with 2mm case thickness was a challenge as it didn't allow fitting the DNA board along the side like I did with Max, so I put it as well as the up/down watts buttons on the front. miniMax has 2, 1000mAh 15A round nano-tech...

I've been tinkering trying to solve this issue with my mods that have user replaceable batts. Not having much luck so far. :( First up - I used a schottky diode. Works great for reverse polarity protection, but is not feasible due to the input voltage drop. With the narrow vaping voltage...

I know there's modders, and vapers, that are up in the air (read: confused :laugh:) on which to choose to mod with, and which to choose to vape with. After modding with, and vaping with, both the Nivel and the DNA20D I have likes/dislikes between the two that I thought I would share...

Dual 18650 AW IMR 2000mAh batts in parallel - 4000mAh total. I switched out the batt contacts that come with this case and used C battery contacts by Keystone. I went for the total black ninja look. :laugh:
