A cigar box can be an excellent structure for building a drumpad composed of 6 force sensors to trigger sounds whose volume depends on the force applied. The electronic used to implement the sensors is a hacked Logitech Dual Action Gamepad for which the analogue sticks can be replaced with 4 analogue sensors.
The cycling 74 team that distributes MAX-MSP has made a complete tutorial on how to hack and use a joypad with Max. The goal is to use the Hi object to get data through HID protocols. The paper sensors can either replace or be put in parallel to the analogue stick if they operate in the same resistance range.\r\n
Each paper sensor has a size of 6*6 cm square and sensors are spaced of a few mm so that the total sensitive area, covered with a drum reactive foam, is slightly more than 12*18 cm square. 4 of the sensors were plugged as analogue sensors in place of the analogue sticks and two of them (on the right) were plugged as digital on/off buttons.
\r\n \r\nA patch was made with MAX-MSP and enables to trigger MIDI percussive sounds (Channel 10), with the sound velocity depending on the force applied for the four analogue sensors.
