    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 would like to have a phone call with a PCB board designer for approximately an hour or less to figure out what is possible for a board I would like to eventually create. That call is all I’m looking for in this project. I want a PCB board designed that is based on the Wemos D1 Mini and has a couple inputs, a 3.5mm stereo jack and a temp/hum sensor. I know the size the board needs to be, ap...

    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...

    This is a re-launched project as the last one was unsuccessful. We need a circuit designing for a simple dual mic-amp-speaker set up so a store member can speak with customers from behind a safety screen, and customers can talk back. 10w 8ohm at 12vdc is fine. It's basically an intercom with volume controls. As well as this, we need to include an induction loop on one side so that custome...
