Krisztián developed an OpenBCI setup with Greentek Geelfree S3 EEG cap for people wo cannot let go:
High alpha means our mind is in a relaxed state. If we cannot let go, we can use Krisztiáns device.
Unfortunately, the Meditation Research Insitute Switzerland (MRIS) was not able to test all the devices we introduced in our journal. We managed to let go with a Fenix 6 and respiration rate, and it was not necessary to test all of those. Is the code for the Fenix 6 from Peter Charlton, PhD? Whatever. Unfortunately, the Fenix 6 does not deliver a respiration rate which is usable for scientific studies. As many of the sensors we introduced in our journal do not deliver data suitable for scientific studies.
We can buy a similar setup from g.tec medical for estimated 50 – 100 000 USD with 32 channels and all parameters. The setup we review here is mainly an open source project. If the people who developed those devices wanted to sell those, they would eventually cost as much as a g.tec medical devices. But open source devices for people who do not need the support from companies like g.tec medical are missing.
Meditation research is a research topic which is quiet new. If we are physiologists, a musicians, computer scientists, sports men, post-doctoral scientists in molecular medicine who tests 100 smartwatches or other persons who cannot let go or want to be a quantitative scientist who wants to measure physiological parametes, try one or the other device we introduce in our journal, we mainly reviewed those. But if we manage to attach those sensors to a single platform as a community project, based for instance on Home Assistant, the device would be much more affordable than g.tec medical devices, and would have a community which is much larger. .
It is a setup which can be used by sports men, but also by people who want to develop devices for clinical applications, such to develop devices which can be used by medical doctors as Cody Rall.
If we look closely at the above video, we can see that Krisztián Hofstädter uses only two channels of EEG. But the alpha signal is quiet good. We can have the same with the Muse Headband and the Mind Monitor. Also there, we can see our alpha waves. We do not have the same graphs there, therefore it is diffult to compare these two devices. The Mind Monitor uses 4 channels of EEG.
These devices are little investigated. But OpenBCI modules with WIFI from Chinese sellers currently cost less than the Muse headband. The Muse SDK is not available anymore. We therefore suggest to use OpenBCI instead of the Muse Headband for developers.
It is also a pity that Shirley Zhang from www.OpenBCI.com does not repair the OpenBCI WIFI shield. Eventually someone new joins the www.OpenBCI.com team to repair it? Currently, an issue-free OpenBCI WIFI shield is only available at eBay Switzerland:
we suppose because the Meditation Research Switzerland (MRIS) was very committed to an issue-free WIFI shield.
But the MRIS does not take any warranty for it’s function. Until now, no users have confirmed that there is an issue-free WIFI shield available, and delivered a proof of it’s function.
