- The MRIS thinks, that the future of low-cost high-quality EEG, ECG, EMG etc. are software platforms based on InfluxDB such as Home Assistant, etc.
- Chinese electronic hardware developers are very skilled, the offer OpenBCI modules in many variants. But we know of little new EEG, ECG, EMG, etc. developements from China.
- Will Chinese or other developers offer a special variant of OpenBCI which is suitable for InfluxDB? According to William Croft from OpenBCI, a hardware change would be necessary to get all the parameters in InfluxDB. With the current modules, parameters like phase and coherence are not available.
- It is highly desirable that modified modules suitable for InfluxDB come on the market. For InfluxDB, single modules might be more suitable. But since software support for OpenBCI is very good, with OpenBCI GUI; LSL, OSC, Python and Brainflow, an additional variant which is suitable for InfluxDB would be very helpful, to make out of OpenBCI a more contemporary open source platfrom.
- Chinese manufacturer does not publish their Gerber files. But if these manufacturers offer all desirable variants of OpenBCI at a fair prize, do we urgently need an open source product?
- Still the question arrises if such a big update for InfluxDB is worth doing, for instance by adding an additional chip with a cache. These are certainly questions for electonic engineers to answer.
- The question arrises also, if we can do without phase and coherence for our own special projects for the time being, until new InlfuxDB platforms are available.
- We have products like MBrainTrain available on the market with 32 or 64 channels. But products based on InfluxDB could reduce costs of EEG devices.
- For future new modules based on InluxDB, an architecture as the one shown in the following video might be simpler:
- And building arrays with these electonic components. But these are also projects which are more suitable for electonic engineers than for us.
- But Chinese developers have proofen that they are capable of producing affordable OpenBCI components and bring them on the market.
- We should study what Chinese sellers and developers have to offer to us: eventually cheaper low-cost high-quality ECG, EEG and MEG modules, which increase the sales rates of those and increase also the size of the community of users and developers.
