A large, Open Source ticker tape #Stocks #FinTech #OpenSource @polygon_io
Polygon.io has put a Wall St.-like ticker tape on top and inside of their office building. Initial commercial quotes were $140k and above, too much.
After much discussion, we asked ourselves if we could make one using commodity hardware and open-source software. Use cheap computers (Raspberry Pis?), normal computer screens and we have all the stock data we could possibly need. We decided to pilot the idea on the inside of the office since outdoor hardware would take additional research.
We wanted to use raspberry pis for the nodes. Although it worked fine running on a Raspberry Pi, making the wiring look nice and clean wasn’t possible. Instead, we purchased some old used Dell OptiPlex 7040 machines for ~$100/ea.
All totaled, the hardware for the setup costs around $6,800 USD. Not exactly cheap, but much more affordable than the alternatives.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
