(WIP)\n\n## Features\n\n* We can use signal device with 4 ports.\n* For example, port 1, 2, 3 assign signal light's \"Green\", \"Yellow\" and \"Red\" leds. Port 4 assign buzzer.\n* Signal device has to have one kind of commonly regulated voltage. I use +24V-0V based signal light.\n  * Final output switcher is open-collectored transister using TOSHIBA \"TD62064.\" https://toshiba.semicon-storage.com/info/docget.jsp?did=2229\u0026prodName=TD62064BP1G\n  * I use ARROW Electronics \"AUSG-24\" (In japanese): https://www.proface.co.jp/signaling/product/product_detail.php?unique_id=AUSG\n\n## Schematic and artwork\n\n* I'll order PCB to [Fusion PCB](https://www.seeedstudio.com/fusion_pcb.html).\n\n![Schematic](images/v1/Schematic.png)\n\n![Artwork](images/v1/Artwork.png)\n\n## License\n\n* Under Apache v2\n\n## Background\n\n* At first, I was exciting agile software development weaves. I made XFD device in 2006.\n  * It was very standard formal style, using the signal light.\n  * I did have no idea how to communicate easy way between PC/Server and devices. So I made with PC's printer parallel port.\n\n![Old XFD by parallel interface](images/OldParallelXFD.jpg)\n\n* Today, we can communicate easier using a lot of procedures, USB/LAN/Wifi/Bluetooth and more. The parallel port obsoleted.\n* I'm beginning to redesign for modern-style device communication. The ESP8266 totally better balanced module for IoT platform. I use ESP8266 and redesign XFD for basic boilerplate :)\n\n## History\n\n* first_pcb: Designed output signal with darlington transistor array. It's very simple board, contains only ESP-WROOM-02 and TrA.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkekyo%2Fextremefeedbackdevice","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkekyo%2Fextremefeedbackdevice","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkekyo%2Fextremefeedbackdevice/lists"}
