Seeking Proposals for Capacitor, Inductor or Resistor Projects

rscasny

I am looking to sponsor passive components projects. It can be anything involving capacitors, inductors or resistors.

 

If you are instrested, please offer your project ideas in the comments below. Also, give me a rough idea of the BOM.

  • Hi Randall,

    I am working on an rfid chessboard project I designed utilizing 125 Khz rfid technology. The main chessboard, for each of the 64 squares, has passive components consisting of a coil and capacitor and fast switching diode. The chessboard scanning is accomplished by multiplexing a few active components, capacitors, and resistors and only requires a few GPIO pins from a micro controller (esp32). The micro controller takes care of deciphering the data stream, chessboard scanning, and signal generation. The micro controller really could be any out there but I wanted to utilize the built-in Bluetooth and wifi that comes with the esp32 later in the project.

    So far approx BOM:

    (64 1n4154 fast switching diodes

    (64) coils ~ 275 uH,

    (70) capacitors

    (15) resistors

    (1) LM324

    (4) 74hc4066

    (2) 74HC595

    (1) 2N7000

    (1) ESP32 sparkfun module
