Question of Peter Gamma from www.petergamma.org:
What is inside this device?
4 TGAM modules?
A 4 ch amplifier?
But the iWorx headband is only around 140 USD. So there must be another principle behind it But can we not make this by ourselves? What is your opinion about this topic? Write it in the comments below.
- TGAM modules start from 23 USD
- 4 modules x 23 USD = 92 USD
- ADS1115 16-Bit Analog-to-Digital Converter is 2 – 30 USD
- The total of the hardware costs of this 4 channel EEG device is around 100 USD
- And the iWorx headband mendioned above is around 140 USD.
- Which means that the iWorx EEG headband is eventually a demo EEG headband built from the components we mentioned, since it is in the same price range. But since it is in the same price range, it is eventually not much more than hardware components without much testing and development.
