Startup idea- market overview

Hello everyone,

I'm a biomedical engineering student and I am developing, as part of my bachelor's thesis, an 8 channel (and a 4 channel, both +2 for RLD and reference) EEG intended to be used as BCI. I am also working on a very simple EMG.

I am interested in opening a small business, entirely managed by me, about simple, cheap but reliable BCI and EMG for makers and students (not "research grade" probably and definitely not medical grade, certification costs are way too high).

I know this is a niche market and there are a lot of products out there, but none of them is actually cheap: the cheapest one is probably from upsidedown lab, a sub-100€ kit with only one electrode, which I find not so good for intermediate/advanced BCI projects involving data training and prediction. I'm planning to stay well under 100€ with the simple 4 channel one, and slightly more for the 8 channel, ADS1299, one: unfortunately the biggest cost, as many of you definitely already know, are the electrodes (that's why OpenBCI sells them separately too. They also have different certification and bureaucracy, at least in Europe).

The idea is to sell the plug-in ready boards (intended for Arduino, possibly with a 12 bit or more resolution and specifically for the R4) with electrodes included, but finding them (certified and cheap) ain't easy.

There are many open-source projects, but I find that not everyone wants to solder some pcb and spend hours making them.

Do you think there is a potential market?

Is there any maker who would actually consider a cheap (related to the market) EEG?

Thank you for your precious advices.

If anyone is curious and finds this idea attractive you're free to dm me ;)

advice for my first earring(/piercing)

EDIT: sorry if this is the wrong community. I will delete the post if needed

(20M) I would really like to ask you if it is normal for it to be slightly "inclined". it doesn't seem perfectly perpendicular to me (basically not "straight": it seems to be pointing slightly downward) . I have done it in a pharmacy, with the pistol. My best friend did 6 there and they are all perfect. I would really like to ask your opinion as my friends are telling me to remove it, wait for it to heal and re-do it again. Thank you very much

hi! complete newbie here

hi! i started my ≈45L/12gal aquarium 3 days ago. the idea is to put some shrimps and some mystery snails inside in the far future

The aquarium was gifted to me by a friend of mine, and so were the plants (I don't know all their names, only sessiflora and bucephalandra for sure)

I would like to ask you if it's normal that the water is still so "brownish" and smell not so good, even if the smell is slightly less perceptible than yesterday

The only thing i tested is the temperature, about 20°C/ 68F

There were at least 3 physa hiding in the plants that were gifted to me. they definitely prefer to stay on the floaters and the upper part of the glass, is it normal? I thought that maybe it's an indicator that the water is not so good.

you can see one of them in the left corner of the tank in pic 1 and another behind the upper part of the thermometer

I used about 2 cm of organic, not fertilized soil and ≈3/3,5 of 3mm black gravel on top of it

the light is 9w, 860 lumens, 4500K. I was suggested to calculate 30 lumens per L, this way i have approximately 22/23, considering the tank is not full and has about 40L, or maybe even less
