NIDAS

NIDAS is an acronym for Networked Information Display & Automation Software. It's an OpenComputers HUD program written by Sampsa, capable of running in-game as a control for power networks, fluid/power monitoring, ore processing, notification of Maintenance issues, AE2 auto-stocking and infusion automation. The source code for NIDAS can be found on GitHub, and its documentation can be found here. Progress into late HV-tier, preferably EV, is required to setup NIDAS as T3 components use Titanium.
Most people set up NIDAS when they unlock the Lapotronic Supercapacitor.

NIDAS requires a top end OpenComputers computer or server to run, with the specs listed below. It can also be configured as a main/local server setup with multiple machines for larger bases. In that case only the local devices will need component busses.

- Computer Case (Tier 3)
- Central Processing Unit (CPU) (Tier 3)
- Graphics Card (Tier 3)
- Memory (Tier 3.5)
- Component Bus (Tier 3), possibly multiple
- Internet Card
- Wireless Network Card (Tier 2)
- Hard Disk Drive (minimum Tier 2, Tier 3 recommended)
- Screen (Tier 3)

Install OpenOS

Install NIDAS (copy into the shell and press enter).

wget -f https://raw.githubusercontent.com/S4mpsa/NIDAS/master/setup.lua && setup

Run a length of OpenComputer cable to the Lapotronic Supercapacitor and set down an Adapter next to it connected to the cable line. (The Adapter has to touch the LSC controller, the cable doesn't have to.)
Get a glasses terminal and a pair of AR Glasses; set down the terminal connected to the computer (range on it is infinite, don't worry) and right click the glasses on the terminal (there won't be any immediate feedback but the glasses' tooltip will have updated).
On the NIDAS machine, click on "Primary Server" under "Available" and click "Activate"; do the same for the "HUD" module; click on "Save" at the bottom.
Click on "Primary Server" again and select "Configure"; ensure that "Main Server" is enabled (should be by default) and click on "None" beside "Power Capacitor"; if you see a long string, that's your LSC, so select it; click on "Save Configuration".
Open the HUD module's config page in similar fashion and select the UUID from the list; enable the HUD elements you want.
Check what your GUI scale is set to in your options and set the scale accordingly (1=small, 2=normal, 3=large, 4=auto).
Check your screen's resolution; if you're playing in fullscreen it's easy, but if you're in windowed then you might have to subtract a bit from your Y resolution.
If you care about the time display, check your time zone's UTC offset and input that.
Save configuration; reboot for good measure; hit "Run".
If everything's good, open the settings pane at the bottom, enable "Autorun", and save.
Don't forget to equip the AR glasses, either as a helmet or in an extra-slot such as baubles necklace slot or Tinker's Construct glasses slot.
