PiCON-OG
3D Printed Lightgun by iCON
Smaller, lighter version of the iCON featuring a sliding recoil, rumble motor, pump reload, analog joystick, 5-way navigation, OLED display, NeoPixel LED in back, accelerometer, screw in wide angle or fish eye lens connection. All parts (including the one-piece frame) can be printed on an Ender 3. The OLED, NeoPixel LED, accelerometer and analog joystick will only work with OpenFIRE firmware running on a Raspberry Pi RP2040 based microcontroller (Pico, Pico W, RP2040 Zero). However, the OpenFIRE firmware is still in development and a release schedule has not yet been announced. Until then, the PiCON can be used with Gun4IR or Samco firmware without those features. This is the original PiCON that was used by many to build a Gun4IR lightgun.
A new version of the PiCON will be released soon with upgraded STLs to support OpenFIRE lightgun builds.
The author marked this model as their own original creation.
