    Design pcb to house an esp32 module and associated electronics to make distance measurements from 10mm to 140mm. Accuracy within +/-10mm. The ultrasonic sensor needs to be mounted external to pcb via a connector. Do not want ultrasonic modules on pcb, u must design that circuit yourself. The esp32 will be going into deepsleep, so u must shutdown any current that will drain the battery. Pcb must accept battery holder. Deliver the following: pcb, schematic and libraries (kikad or eagle) Manuf gerbers Excelfile with bom (digiket, mouser or RS links)

    Medical Amplifier 1 Avsluttet left

    This project is part of a medical device prototype. It is a 110V output amplifier, capable of delivering between 100-3000 watts into an 225 Ohm load electromagnet, operating at frequencies from 4-300 Hz. The ELF parameters made the oscillator circuit of special interest. A simple R555 chip setup may be adequate, though several may be necessary to for complex waveforms.

    Hi all. Using the Arduino IDE, I need to use a microchip SAM L21 MCU in my circuit, with a Watchdog feature. Unfortunately , the watchdog setup is well documented on the SAMD21 chip (lot of tutorials and sample code online), but not on the SAML21, which differs on the internal clock used (if I understood correctly). So the project is the delivery of a functional watchdog code for a SAML21 in arduino, including any necessary original or modified libraries (a good library example of WDT library for the SAMD21 is ) You don't need to have access to a SAML21 hardware, just to provide a functional code that compiles with no error.
