Discontinued The Grasshopper

[ragnorokk]

To go back to claims of different flavor- no one is saying (I would hope) that it has anything to do with contamination or even contact with the metal, the idea was that different rates and intensity of heating led to different flavor profiles coming through at different times and amounts. Which is reasonable, but again, hard to definitely ascribe to the materials themselves.

Also tough to tell if that would make one "better" for flavor, or just mean you need to operate them differently to achieve the same flavor.

It could be true of the GH, after all my black solo tastes better than the silver one. On a side note, this guy felt that the SS has a little cooler draw, which I would appreciate.

 

[zymos]

I don't even know if he had production models of either of them then.

Though if difference was easily noticeable, it probably would be the mouthpiece temp against your lips.

What ever happened to Buzz? He kinda just faded slowly away lol.

Oh I'm sure he's FADED

Hey hey hey Just wondering (while I'm waiting) what the discoloration is in the chamber on the left hand side in this pic . . . . it could kinda look like oxidation of some sort such as copper, & if so, as it's in the air path it would be of concern?

Any ideas/answers?

Can't remember if this has already been covered . . .

I need to be a happy little hopper.

Eventually.

Replacement unit is going strong so far, since it's arrival yesterday.
I did notice the previous unit was getting particularly hot at the seam between the clip and the main body, so I'm on the look out.
I've been trying smaller loads and am in total agreement with the brethren who have as well. It cranks small loads as well as a full oven. Very impressed.
Formidable clouds, zero combustion, and killer form-factor.
Fingers crossed for a longer life span on this puppy.

Sigh, I brought this up earlier in the thread. Some earlier models DO NOT have the extra screen at the base of the chamber. This is why you're noticing the color. It's not oxidation.. just the floor of the chamber which has since been modified, with an extra layer in the form of their hex pattern screen.

 

[VegNVape]

Sigh

Sorry to bother you so. You did not have to reply but thanks all the same, although I must admit that I am used to friendlier responses.

O.k, so some models do not have the screen therefore we are able to see the discoloration. You say that it is not oxidation, do you know what it is?

That really was my question.

My apologies if this has all been covered.

No need to reply if it grieves you

 

[sundaddy]

Isn't it just rainbowed up from the heat?

 

[Wzfbaby7]

Its still kind of strange that they are still sending out faulty units instead of just making sure they are perfect from the start, you know? Will the replacements eventually need to be replaced too? Idk seems like they could just avoid wasting shipping costs an device replacement especially this early in the game but whatever, I wish them the best.

This is exactly the issue my GH is experiencing. It's still working, but uncomfortable / awkward to hold because of the heat there. As I told Trevor in my email to him about this, electronics that aren't designed to create heat generally don't like heat, so this can't be a good thing. He agreed, and a replacement back end is on the way

I read on reddit the SS vs TI comparison from slcbdco, very good news.
The TI has better flavour and the time cooling is faster than SS model.
i'm positively surprised about the flavour thing...

I'm actually confident that this is true and also very likely quite detectable or noticeable......

The Chamber is even lined with thermal material, reducing further direct contact with the actual metal.

for mr me 2:
yeah but the chamber of the grasshopper is lined and the weed is not in direct contact with the metal.
a little conduction is there with no doubt, but is less than a chamber with the weed in direct contact with the metal.

you inhale and the hot air pass through the herb, then shut off the device but the chamber is still a little hot and in contact with the herb so there is a little conduction, but the lined chamber reduce the waste in theory...

Absolutely it reduces but heat energy will be transferred.... some materials transfer faster or slower than others but fact is heat knows no boundaries...... there seems to be a strong consesis the Ti is cooler to the touch than the SS.... so that right there tell us something about absorbing and retaining..

It's a fact that different metals have differrent properties, and I'm sure two GH made of different metals could have measurable differences in performances. But how big would these differences be and are they big enough that a person could notice them? I tend to think not, but who knows...?

Trevor has actually stated that there are performance differences in the anodized Ti GH compared to plain Ti, which again is technically true but probably infinitesimal.

Interesting coincidence I have been involved in some very related testing with the Inhalater mfg were we are testing 2 different sleeves that envelope the heat chamber... well 1 is PBT and the other was PTFE and believe it or not we discovered basically the very same phenomenon.... not only did we notice taste difference but the cloud was also effected.... I think it may have been more noticeable with the Inhalater because of it's Hybrid conv/cond so the effect was quite noticeable.... but I am not surprise at all that the GH with differing shells might also be able to detect minor differences.... It actually made me feel better to read all of this talk of better flavor with a TI.... it was also a better conductor too wasn't it..?

Very interesting stuff .... learning so much here....

EDIT:

A filled oven someone had suggested 15-20 draws. I realize a lot of varables such as heat and and how deep of a draw a person gives. If that's true that would be good. About an evening worth of meds for one person depending on the person. It looks well made by the above picture.

I might want to get a titanium eventually if the colored ones get scratched easily. I do have problems with a short air path being harsh, that is my only issues that I might have.

Listen that heat issue can really be addressed simply by turning it off midway through your inhalation.... just think of it as clearing or evacuating leftover heat from your goodies... of course there is the additional benefit of preserving your flowers flavor longer.... I wouldn't let that hold me back.....

I LOVE THE GRASSHOPPER!

I LOVE THE GRASSHOPPER!

Are you still on the first one?

 

[Stu]

This is strange if true. Ti conducts heat better than SS, so in theory the Ti should be hotter to the touch.

I wish I could shoot some IR pictures/videos of the two versions side by side. Maybe someday...

 

[CarolKing]

Could some of the units run hotter than other units? Maybe we could have some others chime in if you have 2 different styles of GHs.

LoL what m8.. the sigh was more so wtf why does hl still have these in circulation.. yes it was covered, but I wouldn't have responded or provided the information if I was aggrieved..

@Stu - Ti conducts heat better, dissipates heat faster?

 

[zymos]

Could some of the units run hotter than other units? Maybe we could have some others chime in if you have 2 different styles of GHs.

Yes they could, but before anyone can say one way or another, we also need to know if any 2 of the SAME style run at exactly the same temperature. In other words, are any differences due to materials, or due to individual variations, or both?

At this point, the only valid reasons I can see for choosing one over the other are looks, weight and durability.

 

[Stu]

@Stu - Ti conducts heat better, dissipates heat faster?

Ti should move more heat energy through the body than ss, so the dissipation rate would be determined by the flow of heat energy. This makes it hotter, and technically less efficient than ss since it is "stealing" some of the heat energy that could be used to make sweet, sweet vapors.

 

[Snappo]

@Stu - I would love to hear the GH engineer's explanation of the heat dynamics and their effects at work in both the stainless steel and titanium models. Surely they must know the properties of the materials used and their thermal characteristic effects.

 

[zymos]

I'd rather hear about that from a well informed third party...

 

[YaFreekin Right]

This is strange if true. Ti conducts heat better than SS, so in theory the Ti should be hotter to the touch.

Can't say I'm an 'expert'* on the subject but somewhere buried deep in this thread is my analysis between the SS & Ti vapor. Conclusion: The vapor temp of the two units is not appreciably different.

Without knowing the exact alloys used it would be impossible to tell you how the thermal properties affect each style of unit.

The one other factor not taken into account is the thermal mass of the materials.

Using the limited amount of info available I would say.

SS: Slightly lower thermal conductivity, much higher thermal mass. Slower to heat up and longer to cool down.

Ti: Slightly higher thermal conductivity, lower thermal mass. Faster to heat up and cool down.

As previously mentioned , the vapor temp should be approx the same if the units are calibrated identically.

* I have taken upper level courses in heat transfer in the not too distant past.

Edited for incorrectly saying Ti has worse thermal conductivity than SS.
