So for a while I've been working on a material collection assistant, since I found it so tedious to keep track of materials I'd need for specific blueprints and where to find them. While there are some very helpful and great resources available (eg. Engineering Database & Calculator), these weren't as focused or streamlined as I'd have liked.

With my application you can search and filter for blueprints and materials. Once you've found a blueprint or material you'd like to pursue, you can "START COLLECTING". The blueprint and its required materials will then be added to the upper tracking area.

For materials the web-app keeps count of your inventory. You can increase and decrease the inventory quantity for a material by using the plus and minus buttons.

If you remove a blueprint from the tracking area, its associated materials will be removed as well according to the required quantity.

If you craft a blueprint, the required materials will have their inventory quantity reduced. Beware that you can craft a blueprint even if all inventory quantities equal zero. This is a concession to the fact that you'll have to keep the material inventory synchronized yourself.

Unfortunately, you'll have to keep the material inventory synchronized yourself, there's still no way to synchronize automatically with your Elite: Dangerous account. The tracking and inventory state are stored locally on your computer (using a browser technology called LocalStorage).

As far as possible I've tried to make the application layout well in tablets and smartphones.

You can find the collector-drone app here. (

Let me know if you find problems or have suggestions. I'm tracking your feedback in the project, take a look if you want to follow the progress:

  • Update 1.5 (2016-08-02): Update blueprints to 2.1.05.
  • Update 1.4 (2016-07-21): Import and export data.
  • Update 1.3 (2016-07-17): Show which engineers craft blueprints. Numerous layout and style tweaks.
  • Update 2016-07-11: Show collection progress for blueprint and ingredients as progress bar. Find and show blueprints that could be build from current inventory. Fix blueprint category dropdown gets cut off on mobile. Fix blueprints screen shows some materials as Red when they should be Orange.
  • Update 2016-07-09 #2: Fix for removed materials
  • Update 2016-07-09: Layout changed, navigation bar added, data fixes, about page added.
  • Update 2016-07-04: Add pagination indicators. Add fix for 'stuck' materials: untrack all blueprints and reload to clear 'stuck' materials.
  • Update 2016-07-03: "Add to Homescreen" support iOS and Android (thanks lemny)
  • Update 2016-07-02: Data update (additional locations), tweak material location display
  • Update 2016-07-01: Data duplicates removed, mobile layout tweaked for smaller devices
