This project guides you through building a real working Star Trek Communicator using FONA Feather and 3D printing.
• The prop can make real cell phone calls using the FONA Feather!
• The device features a vibration motor, speaker, and microphone mounted inside the case.
• You can customize the buttons to call any number you want.
• The 2500mAh battery is rechargeable over USB and will provide several hours of energy.

Kresmo is an Arduino sketch that uses an OpenAI-compatible API to generate a random and brief pithy saying. The sketch uses the U8g2 library for displaying text on an OLED screen, and the WiFi library for connecting to the internet. The ESP32-C3-0.42 module combines all this hardware into one tiny board.
Using a sine to binary 16 bit number generator I programmed those numbers into a pair of 2716 eproms to get the 16 bit wide sine number 'lookup table' or in this case 'conversion table'. It works incredibly well and my sine/cosine generator drives a large X/Y C.R.T. P.P.I. (Plan Position Indicator 'think radar'). The display has 64K of pixels and the memory storage has the feature of OR'ing old data with new data that will leave a trail behind any moving object. Best wishes on your project.
