If at any point you ask yourself how does this part stay in place, a dab of hot glue works great, and is easily removable.Preface:My friend asked me to make this FilterCam for his Saturn 2. I never really wanted one for myself, but it was fun to make. I sent him the only one I built. When he installs it I will upload pictures of it.ESP32:This adds the ability to change the WiFi connection settings using the SDCARD and a config.txt file. Make sure your sd card is formatted FAT32.SSID=YOUR_SSIDPASS=YOUR_PASSWORDYou can download the ESP32-Cam SourceFILTER-CAM32_for_ELEGOO.rar in thing files.If you want the source where the only thing changed is the sdcard WiFi, then look here::https://github.com/retnel-designs/FilterCam32-with-WiFi-SDCARD-ConfigLED Lamp:With the LED, if you look in camera_pins.h, you will find:"#define LAMP_PIN 2//4 // LED FloodLamp."I connected the LED I specified in the pictures to Pin 2 as the on-board led floodlamp (or flash led) is on Pin 4.Additionally, you will only need to barely turn on the led brightness. Very, Very Bright.The led can get a bit hot, but not too bad if you use reason with the brightness. Brighter means more current, which means more heat. You can put one of these heatsinks on the back of the LED.https://www.amazon.com/gp/product/B07FDWCR12/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Power:The USB filter plug port on the Saturn 2 is 24vdc, you will need this buck converter to step it down to 5vdc to supply the ESP32's 5vdc pin. I also added a small electrolytic capacitor to stabilize the power to the ESP32 to prevent low power brownouts, 47uf / 50vdc - More than a than enough..https://www.amazon.com/gp/product/B076P4C42B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Filter:On the filter part :I included both Short and Long Filters.If you print the short filter you can just put the activated carbon from the elegoo filter."IF" the Long Version, then:I cut a few squares of this filter material to put on the top and bottom, then I filled it with some of the activated carbon from the elegoo filter, and the charcoal filter media.https://www.amazon.com/gp/product/B085H8P6V8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B01GFOORYE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Printing Notes:https://youtu.be/n2tmCohrnkoWinrar:https://www.win-rar.com/start.html?&L=0ELEGOO Heater Probe Resin Tank Clamp:https://www.thingiverse.com/thing:6298823!
