This project include Teensy LC breakout, MPU, LiPo Charger and NOR Memory. It is a board with special request of the customer and the pins can be taken out and adjustments can be made as desired.

The sleep apnea device operates with a vibration motor. Whether the patient enters the apnea is checked with the 9-axis IMU motion sensor and the vibration motor works. The patient is prevented from entering the sleep apnea position.

Functional electric stimulators that produce near-ideal, charge-balanced biphasic stimulation waveforms with interphase delay are considered safer and more efficacious than conventional stimulators. The developed circuit was tested on stroke patients affected by foot drop problems. It was tested both under laboratory conditions and in clinical settings. The key building blocks of this circuit are low dropout regulators, a DC–DC voltage booster and a single high-power current source OP-Amp with current-limiting capabilities. This allows the device to deliver high-voltage, constant current, biphasic pulses without the use of a bulky step-up transformer. The advantages of the proposed design over the currently existing devices include improved safety features (zero DC current, current-limiting mechanism and safe pulses), waveform morphology that causes less muscle fatigue, cost-effectiveness and compact power-efficient circuit design with minimal components.

PCB layout with ALTIUM for a low power control board • $75 USD
I spent more time with him and after 7 example of design he gave me something that I modified to be a professional work. I will never work with him again.

Voltage gain amplifier design • $70 USD
Awesome work ! Cem created the conceptual design and fully implemented with simulation. He even delivered PCB design as a bonus :) I highly recommended Cem for all electronic design and implementations.
