HOHM Wrecker 151W TC ?

Is this, or is this not the chip used in the G2? Be sure to look at the specs AND the pictures.

It looks the same and the chip is manufactured in China, I would say it's probably the same.

They are open about the board being manufactured in China. My understanding is board is designed by hohm tech and outsourced to China, the aluminum housing is machined and the device is assembled in the US.

Found some more interesting information.

It supports triple battery configuration for 200 watts output, it's why they say it's capable of 200 watts.

I will definitely be looking at increasing the 510 tension if it gives me a problem, thanks for the input.

Its not the weakest I've had but it isn't the most stiff either. I am tempted to replace the 510 but it works with the crown and now a hurricane V2.

Nice. Thanks for that 411.

Well I removed the floating pin and same thing. So I removed the coil cartridge and put the rba section in, same thing. I augmented the center pin length with a 2mm screw that I honed the head flat on so the pin would protrude from the bottom a couple mm, same thing.

But the good news is, the hurricane also works just fine, 1.25ohms. Limits, like it should.

Though the problem wasn't the floating pin or the cartridge, it is definitely in the subtank somehow. Tomorrow I'll fabricate a new center pin.

I'm curious as to why the say it will fire a 0.007 ohm coil.

Let's apply ohms law:

1 volt @ 0.007 ohm = 142 amps/watts

Board is 40A safe so with that in mind.

280mV @ 0.007 ohm = 40 amps/11 watts

So what's the point of this claim Hohm Tech?

You're not in a watt war so you say yet the board was designed to do 200W with three 18650 batteries...?

Are you in an Ohm war?

@350ZMO

Good luck fixing your atomizer, hope you get it figured out.

 

[350ZMO]

Well I made a center pin for the subtank out of copper and it works now. I did make it 2 mm longer.

Nice work.

That's not the amp drain on the battery though. Resistance doesn't matter on a regulated device. The calculation is:

Watts (+10% to account for device inefficiency) / battery cutoff voltage (due to the amp draw being highest at that point) = amps

On a series mod the voltages are added (so 6.4 for two batteries), on a parallel mod the amp draw is divided between the batteries, so the amp draw per battery is identical in both cases.

From Phil Busardos website:

"
1. EPT: Electrical Ping Timing - As the coils are heated, it is pinged) just like using the internet or when an officer using radar gun). The amount of time it takes for it to get from point A (starting line) to point B (finish line), determines a value. As metal gets hotter, the ping timing changes (in case of the radar gun, means you're travelling at X value speed).

2. Psycoil - this feature is designed to read the gauge wire(s) within a build. It does this by reading the volume and level of current applied to coils. It takes the collective fluctuation of volts/watts to the 1000th position, and pools this information together and compared to EPT values. This results in delivering precise volt/watts to the 1000th position. Future updates will further fine tune and go to 10,000th position of accuracy.

3. Ohm H/L Spread - using resistance spread (basic values of ohm change as metal heats). This spread is calibrated to pull back once coil(s) achieve any value outside of ohm spread as a safety measure to reduce risk of cotton burn.

All 3 values are used to determine and evaluate temperature and aim to prevent cotton burn. Kanthal is without a doubt the most complex of them due to its tremendous sensitivity, but very doable. We'll continue improvements as time progresses.

just throwing this out there. the dna 200 will fire down to .002 before it says "shorted". hey, does anyone know a good comprehensive site for looking up SMD IC part numbers? i'm trying to find out what certain ic's are responsible for on the wrecker g2 board.

 

[350ZMO]

Yeah that's spin doctoring for marketing, unfortunately everybody does it. Unfortunately though, crap like that sells in every product area not just vaping or mods. I have become insensate to it. Past even amused or amazed anymore. I think Phil does a good job uncovering the electrical performance in his videos.

What I don't see listed that might be important to some is reverse battery protection and atomizer short protection.

I haven't found one. Sometimes digikey sometimes Newark etc, I just google for them. And not all will be out there though you can probably get close Ie narrow it down to flash memory versus a pic.

HOHM tech think they're being cute by sanding off as many of the smd markings as they could. i dunno why they would do that. nobody is going to rip off the board. even with the sanded ic's i can still tell what there functions are! why bother to sand the switching mosfets or reverse batt ptn mosfet? they even sanded the voltage regs and gate driver clean, lol. as far as i can tell nothing special, hardware wise, stands out. software/firmware.........dunno.

 

[f1vefour]

Got the hohm wrecker today but am just too sick to do any testing.

Threw my Zephyrus on it which has dual SS430 coils, put it in XXX mode with the FSK curve set to 13 and it vapes perfectly. 420°F @ 30w.

I wouldn't say no one will rip off the board, every device out there has been cloned. What I will say is hiding the component markings if that's true won't stop cloning.

What's funny is some of the clone boards out there are probably a clone of a clone.

Hope you get to feeling better.

The device isn't as ugly as I initially thought, it is a Yugo though.

Those aren't scratches on the screen, I haven't peeled off the screen protector.

 

[f1vefour]

The indication is the accuracy in Nickel, Titanium, and in power mode.

You never saw Phil adjust the XXX value which is TCR, the device is already relatively accurate when setup properly. Problem is they are trying to generalize (dumb down) the settings to handle all SS and this is what Phil was using..SS mode.

Switch to XXX mode, adjust XXX value (TCR), profit. In trying to simplify the modes they are actually making it less accurate and harder to use.

I was right about this.

In the general SS mode it is quite overpowered at least on the SS430 I have.

I switched it into XXX mode, put the FSK Temp curve directly on 13.5% and it vapes the same as a device with TCR set to 13 but somehow the wrecker is a smoother vape. (Subjective as I'm sick)

420°F @ 30w is a nice warm vape, 440°F @ 35w is much warmer and dense like it should be.

I'm happy with the device in SS mode thus far (11 hours with the device), kanthal may be a different story but I'm only going to test for posterity since I have no interest in this feature.

 

[f1vefour]

So SS mode isn't too overpowered, my ohms had drifted causing it. Overall the automatic SS mode somehow does work pretty well.

I can't find my kanthal (or even my wicking) since I moved recently, I only have one 0.3 ohm stock coil for the Zephyrus. I will test it tomorrow and see how temperature control for kanthal works out.
