It has been many months since I published this Item and the photos are still not completely showing up. If you want to see this item in full, go to: https://www.youmagine.com/designs/ultimaker-esp32-cam This is a video camera designed specifically for an Ultimaker 3D printer. It utilizes an extremely affordable ESP32-Cam module, which can be purchased from Amazon at the following link: https://www.amazon.com/ESP32-CAM-Bluetooth-Camera-Module-Development/dp/B07S5PVZKV/ref=sr_1_13?keywords=esp32-cam&qid=1566655293&s=gateway&sr=8-13 I prefer these modules because they come equipped with built-in WiFi and can run a small web server. This feature enables you to view video images directly using a browser on your MAC, PC, or phone. There are two types of camera lens modules that can be used with the ESP32-Cam: one is a simple 1:1 (normal) lens, while the other is a fish eye lens. I have provided a case to fit both of these modules. A package of three fish eye lenses was purchased from Banggood at the following link: https://www.banggood.com/3pcs-Fisheye-Lens-TTGO-Camera-Module-OV2640-2-Megapixel-Adapter-Support-YUV-RGB-JPEG-For-T-Camera-Plus-ESP32-DOWDQ6-8MB-SPRAM-p-1493572.html?rmmds=myorder&cur_warehouse=CN The normal lens must be positioned on its side to produce an upright image, while the fish eye lens must be placed with the lens facing upwards. This is why there are two different brackets - one for each type of lens. The fish eye lens produces the most effective results. An example photo taken using the fish eye view is included, which can be found at the end of the list. The brackets fit on any edge of the Ultimaker, but caution must be exercised when placing them. If you position the bracket on the left side, it may get knocked off by the print head. Similarly, if you place it on the front of the printer, the print head will press against the camera during filament change operations. I have provided the web server program for the ESP32 (esp32-cam-streamonly.ino) You will require an FTDI interface to program the board using the Arduino IDE. The FTDI to ESP32 wiring diagram is included in the project files. 8/27/2019 I replaced the original "normal lens bracket" file with a revised version that added a slight (0.36 mm) increase in thickness nearest the base of the camera holder. This modification creates a little friction on the camera, which helps to hold it securely in place on the bracket. 9/3/2019 Added fish eye corner bracket to the project. This one is even better than the front mount bracket because it never gets hit by the print head. 9/4/2019 Added normal lens corner bracket to the project. This one is even better than the front mount bracket because it never gets hit by the print head. 9/22/2019 Replaced (esp32-cam-streamonly.ino) file with a newer version that removed unnecessary header files. 9/27/2019 Added an external antenna bracket to the project. This feature allows you to use an External antenna on your ESP32-Cam. I used Fusion 360 to design this "Thing"... Thank you Autodesk!
