Licenses are complex things. Intellectual Property is hard to protect. And although we would like to think that people are going to do the right thing, some will never.
My licenses are quite simple, and boils down to who you are, and what you’re doing:
If you are building a blaster for yourself / others on a non-commercial basis
You can enjoy a free non-commercial license to all my firmware, 3d models, designs, to be incorporated in blasters that you build for yourself, family, friends, etc.
Charging for fair 3d print consumable costs, or other material costs (e.g. a solenoid) is not considered commercial. Charging for your time is.
If you are building a blaster on commission / or for sale or other commercial purpose
You bought an “Airzone” Mosfet, Half-Bridge, or Narfduino hardware product from myself, or another authorised supplier
You can enjoy a royalty free commercial use of any 3d model, design, and firmware for the specific blaster that incorporates this hardware product.
If you bought more than one qualifying product, then you have as many licenses as products.
Qualifying products are Narfduino, Airzone Half-H-Bridge, and Airzone Mosfet boards.
You didn’t buy a qualifying product from me, or an authorised supplier
You must buy a license for commercial use. Licenses are sold on a per-blaster basis. If you are building 10 blasters for commercial purposes, then you need 10 licenses.
The purchase of a license will give you royalty free commercial use of any 3d model, design, and firmware for the specific blaster that it is being used on.
If you are not selling blasters, you still need a license.
You can buy a license on my store.
You have taken my firmware, 3d models, designs, etc and modified them
The above license conditions apply to all derivative works.
Furthermore, while derivative work is of course free for non-commercial use, attribution is required.

Narfduino as a concept owes it’s existence to the Arduino project. In addition, Narfduino is pre-loaded with the Arduino bootloader.
