$2-8 USD / hour

The product is switching an electromagnet on and off to create vibrations at 50Hz. The vibrations are feeded back by an accelerometer and an MCU regulates the amplitude of the vibrations. - review and finalization of schematic. - calculations to prove the schematic. - PCB-layout I have proven the concept with a prototype allready Detailes will be available if you think this is interesting.

This project is interesting for me. I'm familiar with microcontrollers and PWM regulation (I suppose the regulation of amplitude is by PWM, according to feedback), schematic and PCB layout design. I have few questions: - What type of MCU is used? - Power, delivered to electromagnet. - What is the type of accelerometer? - Requirements for design software, if there are? Best Regards, Andrew.
