Hi everyone, The 1st revision (beta) of the FC E-Nail by JCat is now complete. I decided to start a new thread for this, since it's really a project of it's own (what I envisioned for a better enail controller). Features - Easy temperature adjustments with rotary dial - Easy on/off of heater both on device and remotely - Quick temps from mobile screen to go to a temperature with 1-click - Save/Load profiles (PID settings) for different devices (can use auto-tune to generate) - Run scripts for fancy up-temp procedures and the like - Full mobile access including: * Remotely start, adjust temperatures, and monitor * Run scripts * Manage/create/edit scripts with the script editor (drag/drop GUI) * Manage profiles and launch auto-tune to generate - Ability to connect device to WiFi network through device UI - Automatic discovery of device on local networks, but ability to configure if not found or on different subnets Cost to build these is ~$200. Cost will come down if doing batches, but this is the cost sourcing most parts from Canada, and the Omron E5CC-QX2ASM-802 from AliExpress. So here's some pictures! Video to follow Device itself: (this is a first version, I would like to see a standardized 3D printed case built, with "slots" for components to fit in). Also coil button can go away so only one illuminated push button should remain. So going to go to a single "push button" (not switch) like the nicer looking button below. Should be able to cut the device size by 1/3 this way. (ie. screen above and button/rotary encoder side-by-side below) Mobile App: Source code is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License It's free to use the code for personal or educational purposes, but not for commercial ones.

Source code repository location: https://github.com/J-Cat/fc-enail I may in the coming months have some kits available, as I would really like to see these get into the hands of some community members Cost for these kits would likely be $250-$300.
