Microcontroller Jobs

Hello, I need a 2-Cells (500mA) Li-Ion Battery charger but also needs to have a battery State of Health (SoH) measurement. The SoH measurement coud be SPI/I2C/Analog/... The most important think to know is you have to put SOHM in the first and last line of your bid. And that the SOH measurement will be on the charger no with the battery so it has to be measured only when charging. Please feel ...

I need RF soundless frequency emitter. Instead of audio it would just emit downloaded music file frequencies.. What I mean is if playing any music file it would just play out frequencies. Sort of radio emitting antenna. The purpose is instead of a sound (perceived by ears and also by the whole body as a vibrations) be exposed to just vibrations. It needs to have internal memory for loading musi...
