I am looking to sell my complete 16-channel OpenBCI setup (Cyton + Daisy + All-in-One EEG Cap Bundle).

I originally got this for a project that ended up changing direction. As a result, the equipment has been barely used and is in pristine, so I'm letting the whole bundle go for $1,800 OBO (Or Best Offer) (which is well below the ~$3.5k retail price) to move it quickly.

The equipment is in "like new" condition and has been very well taken care of.
Here is what’s included in the lot:

• Cyton 8-channel board + Daisy 8-channel module (attached)
• OpenBCI USB Bluetooth Dongle
• Complete EEG Electrode Cap (pre-wired)
• All standard adapter cables
• Bonus: I'm including a hard-shell tactical carrying case, a gel syringe, and a cleaning brush.

I have attached some pictures so you can see the condition.

Logistics: I am located in San Diego (CA). If you are local (e.g., around UCSD), I would love to meet up for a safe, in-person cash or Zelle transaction. If you are further away, I am happy to ship it via USPS/UPS Priority (we can figure out shipping costs in DMs).

Feel free to send me a direct message if you are interested or have any questions!

Lot includes:

Cyton 8 channel board
USB dongle
9 electrodes (6 wired into home made head gear, plus three extra electrodes)
One set of electrode ear clips
home made head gear (not research grade, but it works for fun experiments
battery holder,
USB cable with Cyton size power plug (to run off external battery or wall charger)
original boxes and sticker

I'm looking to buy a used Cyton + Daisy
Biosensing Board (16-channels).

About the project: I'm the founder of
StrokeRehabOS Inc., developing a multimodal
EEG + sEMG platform for post-stroke motor
rehabilitation. Currently initiating a clinical
data collection pilot (n=40-80 stroke patients)
in preparation for an NIH SBIR Phase I
application (September 2026).

Preprint: doi.org/10.21203/rs.3.rs-9450294/v1

Requirements:

• Cyton + Daisy (16ch) together
• USB dongle included
• All 16 channels functional

Budget: ~$800 shipped to US address (Delaware).

Happy to request impedance test video before
purchase. Please reply here or PM me.

Thank you!

Just thought I’d jump on here to see if anyone was after an 8CH Cyton headset. Bought it for a uni project but don’t need it anymore.

I’ve put it on EBay:

https://ebay.us/m/N6yqLz

Or, alternatively, you could email me if you have any questions or would prefer to chat that way:

reecealex230503@gmail.com

Obviously open to offers since it’s a second hand piece of kit.

Cheers!

If you want to sell a used Open Bci cyton board. Please contact me.
Thanks. Looking forward !

I was a part of a startup where we were building a software tool utilising EEG data. The company went under and so we are selling our equipment. Adding a link for the available equipment, pictures and prices. We are based and Denmark but can of course ship if needed. Prices are negotiable

My name is Tajamul Islam, a passionate student developing an innovative Brain-Computer Interface (BCI) model aimed at helping individuals who are unable to speak by translating brain signals into speech or text.

The model includes powerful features such as:

Real-time brain-to-speech conversion

Offline Mode for fast, local communication

Multi-language support

Voice-free activation using thought triggers

The vision is to build an affordable and accessible solution for the speech-impaired community and beyond. While the idea is strong and development is underway, I am currently facing financial limitations.

I am looking for interested investors or collaborators who can help bring this vision to life. If you're interested in supporting this project or would like to know more, I’d be happy to share a detailed pitch, concept design, and roadmap.

Your feedback, mentorship, or support of any kind would mean a lot to me.
Thank you for your time!

Warm regards,
Tajamul Islam

First of all, I’d like to express my appreciation for the innovative work you’re doing in the field of brain-computer interfaces and neurotechnology. Your contributions are truly shaping the future of this field.

I wanted to propose an idea that could significantly expand OpenBCI's reach and impact: creating a pair of OpenBCI-compatible smart glasses and a TGAM-based OpenBCI version. I believe both of these additions could provide practical, portable, and user-friendly solutions for real-time brainwave data acquisition.

Smart Glasses Integration: With the rise of wearable technology, integrating OpenBCI with smart glasses seems like a natural step forward. Imagine a device that allows users to wear lightweight smart glasses embedded with EEG sensors that can:
Capture brainwave data discreetly in various real-world environments.
Integrate augmented reality (AR) elements for neurofeedback, allowing users to interact with their brainwave data in real-time.
Pair seamlessly with existing OpenBCI hardware/software, opening up new applications for cognitive monitoring, mental health, neurofeedback training, and even gaming. This could make neurotechnology far more accessible and adaptable for everyday use, beyond traditional lab settings.

TGAM OpenBCI Version: TGAM, as a single-channel EEG module, is cost-effective and widely used in consumer brainwave headsets. An OpenBCI TGAM version could target hobbyists, developers, and those in education or early-stage neurotech exploration who may not require the complexity of multi-channel systems like Cyton or Ganglion. It could provide:
A lightweight, easy-to-use, and affordable option for entry-level neurotech enthusiasts.
The perfect bridge for integrating OpenBCI with the existing TGAM-based devices or DIY setups.
An opportunity to encourage innovation at the intersection of consumer-grade EEG tech and OpenBCI’s open-source community.

Both of these ideas would offer a great balance between affordability, portability, and usability. They could attract new users, developers, and researchers looking to experiment with brain-computer interfaces in more casual and non-laboratory settings.

I’d love to hear thoughts from the community on this! Do you think these devices would be a good fit for OpenBCI’s ecosystem? Would there be interest in a Kickstarter or community-driven campaign to get something like this in development?

Thanks for considering this suggestion, and looking forward to the discussion!

Best regards,

I lost the wireless USB dongle for this thing.

I don't know if it actually works.

It lights up and apparently they work if you use SPI (?) in a wired configuration, but I can't vouch for that.

I bought this on AliExpress a couple of years ago and messed around with it for a while with no success.

Then it sat in a box until now.

I don't really care about the money I spent, I just want someone to put this to better use. So, send me an offer that isn't nothing and I will send it to you.

Email is nicky at eegworld dot com

It's not damaged, so if they generally work while wired then this one probably will too.

my experiment seeks to know the effect of listening to sounds and frequencies in the human brain.

Lot includes:

• Cyton 8 channel board
• USB dongle
• 9 electrodes (6 wired into home made head gear, plus three extra electrodes)
• One set of electrode ear clips
• home made head gear (not research grade, but it works for fun experiments
• battery holder,
• USB cable with Cyton size power plug (to run off external battery or wall charger)
• original boxes and sticker
