It also has worked very well at catching skunks which I don't always</p><p>like having in my trap.</p><p>This is an automated door that opens on sunrise and lowers on sunset to prevent</p><p>the night time creatures like skunks and possums from getting caught.</p><p>I took a RC servo and modified it to just a geared motor drive and put on a</p><p>22 tooth gear that raises and lowers the door. The servo listed was easy to</p><p>convert to full 360 rotation and use the metal gear to press fit to the printed gear.</p><p>I used a ESP32 feather from EzSBC to monitor a photo resistor to open and close the door relative to the light level. The Aideepen motor driver draws very little current when both input pins are low so I powered the hole unit from a 18650 cell. It should run for month's without charging the battery. Power to a hall effect sensor and the photoresistor are provided by a IO pin pulled high. The unit draws less that 25 microamps when asleep. Not all ESP32 boards are created equal so if you use a different board you might</p><p>check the current. More info in the source code provided.</p><p>A fun electromechanical project for the advanced maker. Assembly is shown</p><p>in the photo, fit everything first to make sure your ok. I printed the rails laying</p><p>down and had to drill out the rail holes with a long 1/4 inch drill bit. I put a rod</p><p>down these to secure to the trap but you probably don't need too. The doors slide</p><p>on and off very easily but the weight seems to keep them in place.</p><p>I hope this is of some use even if you don't have a Squirrelinator trap.</p><p>Parts used</p><p>Aideepen Dual Motor Driver</p><p>https://www.amazon.com/gp/product/B075S368Y2/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&amp;th=1</p><p>EzSBC Feather</p><p><a href="https://www.ezsbc.com/product/esp32-feather/">https://www.ezsbc.com/product/esp32-feather/</a></p><p>DRV5013AGQLPGM</p><p>TI hall effect sensor latching <a href="https://www.mouser.com/ProductDetail/595-DRV5013AGQLPGM">https://www.mouser.com/ProductDetail/595-DRV5013AGQLPGM</a></p><p>https://www.amazon.com/Uxcell-a13060300ux0519-Unipolar-Magnetic-Detector/dp/B00IFD0F7M/ref=sr_1_5?crid=36PCCTWMWQE1H&amp;keywords=hall+effect+sensor&amp;qid=1642287541&amp;sprefix=hall+effect+sensor%2Caps%2C87&amp;sr=8-5</p><p>PhotoResistor</p><p>https://www.amazon.com/gp/product/B01N7V536K/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1</p><p>Servo</p><p>https://www.amazon.com/gp/product/B00M8TXSBO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1</p><p>Sorry I don't go into more detail but it took me longer to type this and make the</p><p>video that to make the thing.</p><p>Cheers</p><p>Kisssys</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p><strong>Printer:&nbsp;</strong></p><p>I3 MK3S</p><h3>How I Designed This</h3><p>&nbsp;</p><p>Category: Outdoor &amp; Garden</p>
