great update and great communication. too bad things have gotten delayed that is after all what can happen in development. I think you are dong the right things going carefully and methodically now as it will allow you to go faster later!

interesting with buying the laser cutter / capital equipment; depending on the model and its cost it could potentially pay for itself quite quickly!

can you share your basic development plan with us; what are the coming steps / tests that you are hoping to perform?
