Hodl Rocket (Revamped for coinmarketcap api pro)

thingiverse

Hodl Rocket Cryptocurrency price ticket displays up to 10 currencies of your choice from Coin Market Cap. Simply print, glue in place, and wire it up. Load the Arduino sketch plus libraries, and you're good to go. I got this idea from a rocket model I saw on Thingiverse: https://www.thingiverse.com/thing:2317773 I remodeled it to fit a screen display and a nodeMCU for cryptocurrency prices. Both obj and stl files are uploaded. It's a bit rough, but it gets the job done. A button is included if you want to play countdown/takeoff sounds. ---------------------------------------------------------- Here's the list of parts: nodeMCU: an Arduino board with WiFi capabilities ISD1820: a speaker that can record and playback 10-second audio files OLED Display 1.3: a high-resolution display screen 8MM Momentary Tact Button Top Round Head 4PIN: a button for playing sounds ---------------------------------------------------------- Here are the links to videos for instructions: Display: https://www.thingiverse.com/thing:2607585 WiFi Setup: https://www.instructables.com/id/Avoid-Hard-Coding-WiFi-Credentials-on-Your-ESP8266/ Sound for takeoff: youtube.com/watch?v=ckq_CP3ra7g ---------------------------------------------------------- With the sound board, I simply wired up the switch with two wires. One wire connects to 3v and the nodeMCU, while the other (signal wire) connects to the ISD1820 "play_e" terminal. You may also need to connect a 10k resistor between the signal and ground wires, although I haven't done this yet. I used a hot glue gun to attach the display and button in place. I placed the speaker at the top and wrapped it in a sheet of paper for insulation. It's good enough! In the code for the nodeMCU, I also used the log-in manager library to enable logging into the WiFi modem via web browser.
