Parts to build two prototypes have been ordered. I've added the parts I chose to the project component list, I also uploaded a copy of the shopping cart in case anyone wants to see exactly what I order/cost etc.
Once the parts arrive the the first step will be to get the dev boards running, then build the hardware and start generating some tones. In the meantime I can start generating some tones on my PC to see what frequencies/combinations I might want to implement. If anyone has any ideas, please let me know!
Please hit like if you're interested in the project. Now that I've actually put money into this, it will really help me out.
