+Experiments on figuring out how to make Printed Circuit Boards ("PCBs") using the tools and resources at FabLab for an Open-Source Hardware Development, namely development of prototypes for [OLIMEX Teres-A64](https://github.com/OLIMEX/DIY-LAPTOP) and [KREYLIMEX DEIMOS-A64](https://git.dotya.ml/kreyren/OSHW-DEIMOS).
+
+### Method 1: Laser
+
+FabLab Brno as of 01.05.2023-EU has two industrial laser machines Trotec Speedy 300 and 400 the purpose of this method is to figure out if they can be used to make PCBs.
+
+**Projection:** Path of least resistance assuming that the laser is strong enough to evaporate copper and glass fibre.
+
+TODO: Get the experiement approved by the CORE team
+
+#### Material cutting tests
+
+TODO(Krey): Perform a material cutting test on standard blank copper FR-4 board
+1. Engraving in the copper
+2. Evaporating copper
+3. Evaporating Fibreglass
+4. Evaporating Copper and Fibreglass at the same time (to release the PCBs from the blank and possibly make drill holes)
+
+Projected hazards:
+1. Material catching fire
+2. Material reflecting laser beam
+3. Material releasing toxic fumes
+
+Due to concerns of the material cathing fire it should be only performed at size that can burn inside the machine without causing major fire or damaging the machine such as 5x30 mm.
+
+TODO(Krey): Perform a burn test by coating the material in an isopropyl alcohol 99%, flashing it and then recording the result, the material is projected to be self-extinquishing.
+
+#### Verify accuracy of the fabrication process
+
+TODO(Krey): Prepare a benchmark
