# Infidel Sensor ## Description The InFiDEL is a cheap (< $5) filament diameter sensor intended for use with FDM 3d printers. The sensor can be calibrated to provide surprisingly precise filament diameter readings in real-time. The main idea is to use the sensor to correct for filament diameter deviations while printing ## Project Details - **Owner:** adrian95 - **Created:** 3/24/2022 - **Last Updated:** 7/14/2022 - **Visibility:** Public - **Stars:** 1 - **Forks:** 1 ## Key Components ### J2 — [Connector_01x06](https://www.flux.ai/adrian95/pin-header-01x06-2p54mm-vertical.md) - Manufacturer Part Number: Conn_01x06 **Pins:** - Pin_1 - Pin_2 - Pin_3 - Pin_4 - Pin_5 - Pin_6 ### J3 — [Connector 02x03](https://www.flux.ai/adrian95/connector-02x03.md) - Manufacturer Part Number: Conn_02x03_Counter_Clockwise **Pins:** - Pin_1 - Pin_2 - Pin_3 - Pin_4 - Pin_5 - Pin_6 ### J4 — [Connector_01x06](https://www.flux.ai/adrian95/pin-header-01x06-2p54mm-vertical.md) - Manufacturer Part Number: Conn_01x06 **Pins:** - Pin_1 - Pin_2 - Pin_3 - Pin_4 - Pin_5 - Pin_6 ### LED1 — [LED 0603 (1608 Metric)](https://www.flux.ai/jharwinbarrozo/led-0603-1608-metric.md) - Part Type: LED **Pins:** - A - K ### U1 — [ATTINY85-20SU](https://www.flux.ai/adrian95/attiny85-20su.md) - Manufacturer Name: Microchip - Part Type: Microcontroller - Datasheet URL: https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-2586-AVR-8-bit-Microcontroller-ATtiny25-ATtiny45-ATtiny85_Datasheet-Summary.pdf - Manufacturer Part Number: ATTINY85-20SU **Pins:** - ~RESET~/PB5 - AREF/PB0 - GND - PB1 - PB2 - VCC - XTAL1/PB3 - XTAL2/PB4 ### U2 — [A1302EUA-T](https://www.flux.ai/adrian95/a1302eua-t.md) - Part Type: Sensor - Manufacturer Part Number: A1302EUA-T - Manufacturer Name: Allegro MicroSystems - Datasheet URL: https://octopart.com/datasheet/a1302eua-t-allegro+microsystems-38945114 **Pins:** - GND - OUT - VCC *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/adrian95/infidel-sensor](https://www.flux.ai/adrian95/infidel-sensor).* --- *Generated from [https://www.flux.ai/adrian95/infidel-sensor](https://www.flux.ai/adrian95/infidel-sensor)*
