Here's the method I use for weighing out powder with my Gemini-20:
Using this method and a set of calibration weights I confirmed my scale is usually accurate to within 1mg.
Edit: Also if you add only very small amounts of powder at a time and the scale does not register it, you can touch the paper lightly with your scoop and then allow it to settle back to an accurate weight.
costco should get an amazon account:

Fold these diagonally twice so that you form a point in the middle of the paper, put it on top of the bowl, weigh powders. I can weigh all my powders directly onto this paper (by taring in between powders) and then ingest the powder off the paper. Great stuff, holds at least 6-7g total of powder.

i've used these in the past they're great. plus you basically get lifetime supply
Will last you a long while
These might be of use:

Sparkfun also sells an assortment of things:

Any of these will probably require you to write a GPIO interface program to get the data. You might also use this board: https://www.sparkfun.com/products/13261 if you don't mind paying a little bit more to have a microcontroller interface between the Pi and the load cell

Definitely MDMA or speed if you're in the college scene. 20g amphetamine paste (So around 15g dried) for $60 and you can sell that for around $100 a gram as powder or $10-$15 for 80mg in a cap.
So $65 for the tools to make good capsules. From here you can either spend $60 on 20g of speed paste or buy some ecstasy. If you do the 20g of paste you'll likely wind up with 15g of powder, enough to make 187 80mg speed capsules. If you sell for $10 each, that's $1,870. Minus the initial investment of around $140, you're left with at least $1,730.
It was actually really cheap - just $10. Here it is on Amazon. I bet you the Arduino would cost more, but I had one lying around for years so I can't give you an exact cost.
Here ya go
I have no idea why the price is up to $15. I know I paid $5 and got 500...but it really is a lifetime supply (or at least 2 years for me). Best investment for powders aside from a mg scale for sure.
Cellulose based btw
Please don't do this. Get some good weigh papers from Amazon. They work even better and are super cheap.
Maybe you don't use receipts for this often but there's no reason to subject your body to the chemicals that coat them any more than you have to.
If you are just packing the capsules full of powder, you can use a capsule filling machine. I recommend the capsule machine as I've used it to pack powdered shrooms into size 00 capsule (0.5g in each).
If you are working in smaller quantities then you'll have to fill each capsule individually with a spatula. It is time consuming, but there's something tranquil about the process. I'd put some weigh paper onto your scale and add powder with the spatula to the desired weight. Fold a crease into the weigh paper beforehand so you can use the paper to slowly drop the powder into the capsule. Repeat.
I filled about 13 size 5 capsules using creased weigh paper. The capsule machine can also help with smaller quantities by holding your capsules and minimizing spillage (put some tape over the nearby holes). Unfortunately, there are no affordable size 5 capsule machines so I had to hold them very carefully.
I believe you are talking about [stanchions] (https://www.amazon.com/US-Weight-Sentry-Stanchion-Retractable/dp/B01ITDEB2C).
You should also do volumetric dosing (im sure someone else will tell you how to do it), but check out this deal on a chemistry scale: https://www.amazon.com/x0-001g-Analytical-Precision-Electronic-100x0-001g/dp/B0761H8F5S/ref=sr_1_24?crid=1MO8NC39AB2Q3&keywords=mg+scale+0.001&qid=1569344156&s=gateway&sprefix=mg+scale%2Caps%2C-1&sr=8-24
$65 bucks and you can weigh samples that are a couple mg. That model is a slight hassle to use. If you get a chemistry scale also get micro scoops and weight boats. Lastly you have to leave this model on for a few minutes to get a good measurement.
What most people here probably use (doesn't do well below 10mg, can't be used for less than 5mg) costs $40: https://www.amazon.com/American-Weigh-GEMINI-20-Portable-MilliGram/dp/B0012TDNAM/ref=pd_cp_328_1/143-8917797-1216210?_encoding=UTF8&pd_rd_i=B0012TDNAM&pd_rd_r=d9733b71-dabe-41b1-aba8-9b7671b2eef3&pd_rd_w=I34Yl&pd_rd_wg=FrGju&pf_rd_p=ef4dc990-a9ca-4945-ae0b-f8d549198ed6&pf_rd_r=FKZGZCE0N01YZ1CY713N&psc=1&refRID=FKZGZCE0N01YZ1CY713N
