The beginning of the circuit
At this point, we made leds and photodiodes working correct and reading data from it.
Babysteps of circuit
We have built our first working hardware system.
First Tests On The Head
The design had been tried to see if it the results are accurate or not.
Pulse Oximeter
We have designed a pulse oximeter circuit and its box for reading data correct. And elegant style seems nice.
Our handmade powerbank circuit
We made a powerbank for mobility and it is handmade powerbank lasts longer then other powerbanks and much cheaper.(It is not mandatory to buy but please do not buy another powerbank because it produces the voltage that circuit needs others can cause damage for circuit)
Now we are taking data from hardware.
After we put hardware to headband we are now taking data from user.
The last figure of Headbang
It is not the final design and despite this, it can checks data correct.
