Open Source DLP-Printer "DLPrinter"

The whole project is currently under heavy development and not even close to being finished. Since about a year now I've been following different sources of DIY DLP/SLA printers and decided to start my very own project. All parts are designed in a way that they're as easy to be printed on an FDM printer as possible! Also, unlike many approaches, I want to use different hardware resources. What's done so far: 1. Hardware setup 1.1. Setup OrangePi with Armbian 5.30. 1.2. Configure Armbian to enable GPIO, WiFi to userlevel roles. 1.3. Get Electron - Electron Quick Start app up and running. 1.4. Setup and configure LCD for UV light projecting. 1.5. Setup hardware (transistor, resistors) to drive 10W UV Lamp 390nm from GPIO. 1.6. Setup Hardware (simple example setting with capacitor and 1/32 micro steps) to drive DRV8825 stepper driver from GPIO. 2. Software development 2.1. Express based webserver up and running. 2.2. Communication between projector/webserver/gpio threads. 2.3. Communication with GPIO working. 3. Design and build 3.1. Design of Z axis parts. 3.2. Build of Z axis parts. 3.3. Design of first draft of OrangePi expansion board (try to keep rPi compatible). 4. Documentation 4.1. Created this thing on Thingiverse. To-Do: 1. Hardware setup 1.1. Assemble all parts together as soon, all case parts are done. 1.2. Finish and etch OrangePi expansion board. 1.3. Some testing about burn time with the hardware setup. 2. Software development 2.1. A damn lot of stuff. 2.2. Do a nice and usable page for the webserver. 2.3. Finish work on projector (different input file types possibly). 2.4 Improve installation capabilities (probably this project will be running on rPi's, BananaPi's, whatever machines and types). 2.5 Upload the whole thing to github.com. 2.6 GCode interpreter planned to reuse slice data from any slicer application (CraftWare, Cura, Slic3r). 2.7 Extensible configuration options. 2.8 BuiltIn SVG slicing capabilities (most likely will integrate slic3r ). 2.9 Build runner (the actual printing process) into projector thread. 3. Documentation 3.1. Write a BOM. 3.2. Create a source code documentation. 3.3. Create a "HowTo Build". Github repository Even though this thing is not even functional yet, I uploaded a repository on github. BOM (Work in Process): * 12ea M3x20 screws * 2ea Smooth rods * 1ea Leadscrew 8mm with nut * 1ea Nema17 motor with driver (recommended DRV8825) * 1ea Motor capacitor (35v 100uF) * 1ea NPN transistor capable of driving the UV LED * 1ea UV LED (10W 390nm in testing right now) * 1ea Computer (Single bord PCs or whatever, shouldn't matter) * 1ea LCD Display (7" 1024x600 in testing right now) * 1ea ATX PSU * 2ea either LM8uu's or Triffid Hunter's Bushings (see below) * 1ea 608z bearing (will probably design a nylon part for this purpose) A couple of resistors (for the led, as well as pull down transistor)
