    I need to simulate a project involving a thin film transistor using Zinc oxide as semiconductor material with varying channel length of source and drain electrode and Aluminium oxide as dieletric layer. This simulation should be done using TCAD atlas silvaco. I have the file here. I couldn't derive the ID vs VG waveform with larger current. It would be great if u helped me to simulate this project. I need this project by Friday this week (8 July 2022)

    I have firmware for an ESP32 device written for PlatformIO (basically arduino), but it has become very long and messy. I need help removing any redundant functions that are not being used, and creating a library with all the remaining functions. This will alllow the file to be less cluttered as it will call its functions from the library file. The ESP32 firmware controls a device with an ADXL accelerometer, an optional GPS unit, ethernet or wifi connectivity, LEDs and a buzzer. After starting up its peripheral devices it checks if ethernet is connected, if not it uses Wifi with Smartconfig protocol, then connects to AWS. This is done using AWS certificates stored in the SPIFFS memory. Once connected to AWS it collects the ADXL FIFO buffer of accelerations every second and sends them t...

    Looking to build a simple smart weighing scale. Features required are - - Device should be small - shape & size of a coaster (circular, but not very thick) - Should be cheap to make & easy to replicate - prototype can be around $10 - $15, but if it needs to be mass manufactured, we would need to do it around $3 - $4 - Device should be battery powered (flexible on battery capacity, based on cost) - ideally rechargeable battery - Maximum weight expected would be 1 - 2kg - Require precision of 1g - Device should have a button, which when pressed sends the weight data - Device sends data to a web API / via Bluetooth (either is fine)
