I have successfully developed most of the pad hardware to be easily recreated and will develop 6 pads within the next few weeks for our minimum viable product. Using the Arduino Pro Mini 3.3V allows for easy reprogramming to calibrate for any threshold modifications needed. Usually will have to do with time latency window in between hits as well as the minimum voltage threshold floor. There usually might be very slight differences in tolerances because of the piezo disc manufacturing.
Finally, I will finish implementing digital playback audio on my central hub so that the system can be a stand alone product to be able to produce its own sounds. Furthermore, I will start implementing code on a separate daisy seed so that we can create a dual-networked system splitting the 6 pads into 3 pads for each player.
I would say I am pretty on schedule and in order for the whole team to be on schedule I will try to see in what areas I can help out with the assembly of the product on the software and networking side.
