My name is Alex Precosky, and this is my public spot on the internet to show whatever personal projects I may have been tinkering with.
Check out some programming projects on my GitHub page.
Also there is my BitBucket page, which I used before GitHub, and have a few things left there too.
Selected Projects
LED Tile
An Altera Cyclone IV FPGA driven 32x32 LED tile animated display with a Nios II Core soft CPU, complete with an HTTP API served over WiFi by an ESP8266. It hangs in my hand-stained wooden case above my workstation.
IoT Temperature Sensor System
Sensor, gateway, database, and dashboard showing off a complete IoT system for monitoring the temperature...of my refrigerator. Based on Zigbee mesh networking for the sensors, an Eclipse Kura based gateway for which I wrote a Java OSGi applications to host the data on an MQTT server and send telemetry to a MySQL server, and a Python/Flask based HTTP API serving historical data, displayed on a simple web dashboard. The gateway's MQTT server is bridged to that of the AWS IoT service, which then JSONifies the representation of the sensor via an AWS Lambda, which goes into an AWS IoT Analytics pipeline to make longer term averages and also raise an alarm if the fridge gets too hot.
Dead Man's Switch
An Ethereum blockchain based distributed application that will release a block of private information such as an important secret or an encryption key to a trusted third party upon your death or capture. Team project done at the Bluzelle Decentralized Database hackathon. It is deployed as a smart contract on the Etherum network written in Solidity. The front end is written in HTML/JavaScript and uses the truffle and web3 libraries. In about 36 hours our team got it fully working and fairly well polished!
