OpenCat Nybble DIY

thingiverse

Update 1/4/2020: Added a new STL option for the eyes that should fit a SR04 sensor. Update 12/5/2019: After last night's down time for maintenance, the upload function seems to be working again. I have re-uploaded all 25 files and they appear to be downloading properly again. Please use the regular download function and let me know if any issues crop up. Update 12/4/2019: Thingiverse is acting up and will not let me upload the files properly because their site is broken and buggy and probably completely overwhelmed. Please check comments from today's date for a temporary link to the files stored in OneDrive. This is my Do It Yourself version of the OpenCat Nybble robotic kitten by Petoi (as seen on the cover of Make Magazine, Volume 70 Oct/Nov 2019). You can support the project on the Indiegogo site (https://www.indiegogo.com/projects/nybble-world-s-cutest-open-source-robotic-kitten#/) where you can buy a full kit or even just the electronics board. Source code and schematic is located at https://github.com/PetoiCamp/OpenCat Using only the Magazine article as reference, I have designed my own, duplicate, 3D Printable frame so that you can print your own or even use my design as spare parts to repair your official lasercut kit. Electronics required are as follows: Arduino Pro Mini 5V 16Mhz EEPROM 24LC256 MPU-6050 Gyro Piezo buzzer 1500UF 16V High Temperature Aluminum Electrolytic Capacitor https://www.microcenter.com/product/429755/nte-electronics-vht1500m16-1500uf-16v-high-temperature-aluminum-electrolytic-capacitor Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685 https://www.adafruit.com/product/815 QTY (11) MG90S Metal Gear Servos https://www.amazon.com/gp/product/B07R7PYK9T/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 38 KHz IR Receiver https://www.microcenter.com/product/476345/velleman-1838-ir-infrared-379khz-receiver---2-pack Compatible IR Remote (I chose this 44 button remote from Amazon and modified the Arduino Code to match) https://www.amazon.com/gp/product/B00AF5YOK2/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Ultrasonic Range Finder for Eyes (SRF05) https://www.amazon.com/s?k=srf05&hvadid=77927986214133&hvbmt=be&hvdev=c&hvqmt=e&tag=mh0b-20&ref=pd_sl_89epxwbpkb_e
