Peter Gamma from www.petergamma.org
needs help from final year engineering students from India
Or from other experts. He wants to build a 3 channel gold standard ECG device with a spirometer. This requires 4 channels with at least a 16 bit A/D conversion rate. OpenBCI Ganglion would full-fill these requirements. OpenBCI Ganglion is around CHF 459.00 which is around 500 USD in the www.openbci.com shop. Shipping and import taxes included, this gives around 700 USD for Swiss costumers. Components like the Ganglion are sensitive. If used everyday, they can easily break. But warranty time of products from www.openbci.com is short.
Peter Gamma from www.petergamma.org was looking for alternatives to products from www.openbci.com. There is OpenBCI made in China and PiEEG. But no one could convince Peter that it is worth buying those, since no one could proof in a convincing way that these modules work without issues.
So should Peter go back to products from www.openbci.com? Are these not an outdated concept 10 years after they have been launched? There where some attempts to use products from www.openbci.com for ECG in the www.openbci.com forum. But why does no one from top universities like the Swiss Federal Institute of Technology in Zurich use products from www.openbci.com? Right, there is one exception as far was we know, if you have a deeper look at it. But is this exception even worth mentioning it?
The alternative would be to be courageous and make a big step forward. There is an interesting video about the ADS1115 16-Bit Analog-to-Digital Converter from How To Electronics who is a guy from India:
And do Indian guys not fit well to Peter Gamma from the Meditation Research Institute Switzerland (MRIS)? Better than some guys from the United States such as former OpenBCI enthusiast A. J. Keller from Neurosity?:
Peter does not know if the ADS1115 is suitable for physiological devices like 3 channel ECG devices. But why should it not be? And in the end, if the final year engineering students from India do no help Peter, is there another way than starting doing experiments by himself, to see if he finds an answer? And eventually testing both architectures and comparing the results to each other is also an option. Since doing things like these is Peters lifetime journey. So comparing both architectures is an option for Peter, and hopefully also for the final year engineering students from India.
