    The purpose of this project is to design a 760V to 12V DC/DC converter to be used as an integrated auxilliary power supply within various products operating from a nominal 760 VDC source. A possible converter design could be based on off-line power switches but with the main difference that the input voltage is higher than what most off-line switchers on the market can handle. A staged project se...

    The smart charger allows a user to switch the charge process of e-bike lithium batteries off earlier: at 40% (winter storage - degradation is minimal), 60% - 70% - 80% (save lifetime and decrease driving range) and 100%. Switching off takes place based on the voltages that correspond with the 4 "save" positions. As this is not 100% accurate, the switching points are recalculated by mea...

    I’m looking for someone to design a PCB board that is essentially a Wemos D1 Mini board connected to a few inputs and outputs. The board would need to be about 58x34mm in size. Inputs are temp/hum sensor, 3.5mm stereo jack, and button. Output is a buzzer. I’m new to PCB board design so I’m sure I will need to speak with the designer to explain further. I know I don’t need a...

    My circuit is consuming 18mA at standby and 24mA when activated (LEDs twinkle) - at 3.3V based on the code that I wrote. I want you to use my code and introduce low power techniques such as sleep mode, low power mode, PWM, Gamma correction, etc, to reduce power consumption. I want to document the progress of the power consumption from the initial value of 18mA at standby (24mA when activated) to...
