You want a digital scale for What??

[GlennSprigg]

Ha!!  I found this accidentally, on eBay...

Digital Electronic scales, for only $8.50 !!  I can't IMAGINE what prospective purchasers would
want it for, (?). Would be neat for all the 'above-board' uses they recommend, I suppose.   
The pictures confused me for a while, until I realized that the whole thing is the size of a typical
car Remote, and the outer cover makes it 'look' like that's what it is!! I guess there's a market... 
P.S.
I do not condone drug usage. Never have, and never will, except from my Doctor!

What, you never put sugar in your coffee?

That is one very very tiny scale alright. But there are other uses than drugs for small scales.

Some people have chemistry as a hobby in the same was that a lot of people do electronics as a hobby and they do sometimes need to weigh out tiny amounts of stuff.

Very sensitive scales are scientific equipment in general, used for determining the amount of something. For example some of the hermetically sealed ceramic chips in the space program are tested by putting then under water under many bar of pressure for a while and then weighting them afterwards. If they gained a few milligrams of weight that means something got in. Sensitive scales can also be used to quantify tiny forces in experiments, like for example if you are building some sort of electrostatic actuator.

Some vinyl enthusiasts want to measure the tracking force of there record player to make sure its dialed in properly to not destroy records. This also needs a scale small enough to fit under the stylus and sensitive enough to measure down in fractions of a gram.

Ok, that car-key camoflage really is quite sketchy.
But those tiny scales are quite useful for making small batches of spice blends and weighing some food additives or food coloring. Fitness people who're into mixing their own supplements need fairly accurate scales. People who make their own soaps, cosmetics and perfumes.

A precise scale is a must-have for anyone whos into any form of applied chemistry, and then the choice is between the 10-20 € Ebay variant or the 500 - 2000 € name-brand lab scale.

100 g is appropriate for weighing mail:  US Mail prices go in 1 oz av = 28.4 g increments for first-class postage.
However the eBay vendor does not ship to US.

[DrG]

This one is obviously for weighing female to male stereo jack adapters.....I also found it "accidentally"

I was actually thinking about one of those a few days ago, figured it'd be useful for measuring out some epoxy.  I only need a few grams mixed up, and the resolution on my kitchen scales only goes down to grams.  The OP's one is really small though.

[RoGeorge]

I have in total 4 digital scales (and a few other scales with mechanical springs).

- One is a body weight scale, upto 200? kg, resolution 100 grams, good to see how fat I am
- One is a kitchen scale, upto 5 kg, resolution 1 gram, good for food recipes
- One is for upto 100 grams, resolution 0.1 gram - good for small items, medicine pills splitting, weed, gold jewelries
- One for upto 50 grams, resolution 1 milligram, good for chemistry, diamonds, precise medicine or chemicals mixing

Some dude needed a microgram balance to weight an eyelash, therefore he built one himself:

Scales like this are frequently used for measuring the powder charge when reloading ammunition.  They are not preferred for a number of reasons (like reliability) and there are more appropriate scales for the task. But you can't beat the price!

This particular unit measures in 0.01 grams which is 0.15+ grains and we typically want to measure to the nearest 0.1 grain (and try to split that 0.1 gr when using a beam scale).  This unit won't do that.

FWIW, there are 7,000 grains in a pound.

[NivagSwerdna]

I have one of these and use it for measuring panacur for tortoise de-worming... I'm surprised everyone doesn't have one.

[themadhippy]

Ive got a set similar  to those for measuring white powder,and a freezer full of green leaf material.But  having brewing salts and hops in the uk isn't  illegal

[BravoV]

For what ?

Clearly ... obviously .. for you to spam general chat area. 

[SiliconWizard]

Well, I don't know, this one seems very small indeed. But I do have a small (but still larger than this) precision scale that can take up to 2 kg, and it's handy in your lab - when you need to accurately weigh components/boards with better than 1 g accuracy.

100 g max seems pretty low, but it could still find uses in your lab, for weighing electronic components, (small) boards, chemicals when you need to make accurate mixes, etc.

[Siwastaja]

Oh boy was I delighted when I could buy Chinese precision scales in, uhm, 2008 I think? Dealextreme was a fairly new thing, then I found out about Ebay selling this Chinese crap. (Crap being used in positive meaning, this is.)

I got a 0.01g resolution, max 300g scale first, then a 0.1g resolution, 2000g one, and finally, a 0.001g 20g thing. All below $10 IIRC, and they all came with calibration weighs. None of them are as good as $1000 scales with similar specifications, but no ones expecting that. The bang-for-buck is great.

Even the first one still works, after over 10 years of almost daily use. I check the calibration every few years. These seem to be repeatable, I would even dare to suggest accurate, to about +/- 3 least significant digits and have a minimum measurable offset of about 7-10 least significant digits.

What for?

Yes, I did some chemistry as a hobby and later professionally as well. Was developing films and built a motion picture film processing lab. Of course, for the short while as a professional motion lab, I mostly used prepackaged Kodak kit chemistry but I still mixed some solutions like black & white developers or experimental processing solutions from scratch. I also experimented doing the film itself, this is, black&white emulsions from scratch, using food grade gelatine, silver nitrate made from dissolving silver into nitric acid (beware: deadly gasses emerge!), bromide and iodine salts and some other special sensitizing agents I already forgot about. The combo of science + art of growing the microscopic silver halide crystals through careful process control (temperatures, stirring, chemical injection rates), affecting the film's sensitivity, graininess and resolution, was indeed interesting. A strange mix of very low and high tech, when you can produce a 100-megapixel equivalent image by a process consisting of only mixing basic chemicals. This is how it worked for well over 100 years - and of course, it still works.

Now I mostly use the scales for weighing coffee. 24 grams per 0.5 liter of water, oh yes.

[madires]

... for counting electronic components the easy way.

[rdl]

I have a scale similar to that for weighing chemicals. The amounts needed to mix small batches of hydroponic nutrient solutions can be pretty small.

[dnwheeler]

Coin collectors have small scales to help detect counterfeit coins.

[RoGeorge]

Again, my 0.1g resolution was bought for weed checking, very, very long time ago.  It was nothing wrong about it.   

[David Hess]

I use mine mostly for grading cases and bullets and for weighing power charges when reloading.

[james_s]

That looks a lot like the scale I use to measure the tracking force on turntable needles.

[SilverSolder]

Some more use cases here:

1) Weighing ink cartridges (for inkjet printers) so I know when they are running low and ready to refill...

2) Weighing yogurt culture powder

3) Weighing yeast powder

[Alex Eisenhut]

I was weighing quadcopter blades for reasons. Turns out it makes no difference as far as I could tell...
Then I got a blade balancer and the motor was shaking more with a balanced blade.
Now I don't weigh anything anymore. 

[Macbeth]

No drug dealer would ever bother with 0.01g resolution. Before these cheap electronic scales a low end dealer would just use a traditional small beam balance scale and the "calibrated" 1 gram weight would be a single cigarette out of a 20 pack (which would be 1g +/- 0.2g). They would put their finger on the scale anyway.

It's absurd to think these electronic devices are for common drug dealers. 

Having said that, they may be useful to a Carfentinal dealer (usually the CCP) who decides on providing samples to a top level Mexican cartel gang? The kind of people who will do an LD50 test on the local populace before diluting it 10,000 times to sell as street heroin? I'm sure these billionaires are very happy that they can save a few hundred bucks on AliExpress.

no need for fancy weights to check your weed deals,1 uk penny=1/8 and 2p =1/4
