Polygon.io has put a Wall St.-like ticker tape on prime and within their workplace constructing. Preliminary business quotes have been $140k and above, an excessive amount of.
After a lot dialogue, we requested ourselves if we might make one utilizing commodity {hardware} and open-source software program. Use low-cost computer systems (Raspberry Pis?), regular pc screens and now we have all of the inventory knowledge we might presumably want. We determined to pilot the concept on the within of the workplace since outside {hardware} would take extra analysis.
We wished to make use of raspberry pis for the nodes. Though it labored effective working on a Raspberry Pi, making the wiring look good and clear wasn’t potential. As a substitute, we bought some outdated used Dell OptiPlex 7040 machines for ~$100/ea.
All totaled, the {hardware} for the setup prices round $6,800 USD. Not precisely low-cost, however far more reasonably priced than the alternate options.
You possibly can learn extra within the article and see the code on GitHub.
