The hardware aspect is mostly done and just needs to be reproduced to be able to make 6 pads. There are a few things that need to be modified however. We were originally using a plexiglass/acrylic material for our impact plate but making 6 of those were difficult due to the inability to laser cut them so we changed to acrylic which is a lot denser than the plexiglass. This does have its downsides because the dampening of the acrylic is most likely a lot less than the plexiglass. Therefore, there will most likely be a lot more double hits registered due to residual sound waves as I noticed in the interim demo.
A short fix for that is that I can increase the debouncing window on the arduino code to account for the residuals or increase the threshold for activation.
Some other variances with the hardware that I noticed was that the rims could register shots but there was low dampening from the environment which is not ideal. A fix for that is adding rubber pads on the screw heads of the pads so that the rubber can act as the dampener from the environment.
One concern is that I noticed that some of the piezos on the impact plates I just made had a very large negative voltage spike compared to other pads which were mostly net positive peaks. It could be an issue with the soldering but I will have to test it in the entirety of its configuration to be sure.
Lastly, for future steps I am planning to incorporate another daisy seed central hub with configurable settings such that 2 users are able to play multiplayer over a network with each daisy seed acting as a client server interface.
