A friend of mine recently began to realize his rather long-standing dream of playing drums. But almost immediately a problem arose: except for courses, there was no place to practice. Even more narrows the range of opportunities the student budget. To help, it was decided to build a simple practise pad, in order to simply turn out the technique. Further more. And everything gets better with Guitar Hero!
PS: Everything has already been collected and transferred to another city, so there will be few photos. ')
PPS: Video Updated! At the heart of the design is a wooden shield with dimensions of 800x170. It is cut into 5 equal parts, 4 of which are ready for use, and the fifth is to be cut into half and 2 quarters. Half will be the basis for the pedal, the rest of the chaotic cut turns legs.
The next step will be the manufacture of surfaces. We need an elastic material that can compensate for the blow and muffle the sound. To do this, take two car mats. Cut out 2 circles with a diameter of about 15 cm for each pad, glue with the usual moment without a press, in order to maintain elasticity due to the original relief of the mats.
With the same moment, but with the use of force, we glue the wooden legs to the far edge of the surface. It turned out the most common praktispedy.
Next, the boundary area of ​​mechanics and electronics. We have two stationary points of support, to which we add a third, functional, which will short circuit to fix the blow. Realizations of the third “foot” can be thought up quite a lot, under the cut all the failed solutions are collected.
In the end, it turned out such a system. As contacts were used pads for the spatula. They are quite elastic and conduct current.
We animate everything with a ready-made keyboard I / O. Solder one wire to the x coordinate, it will be common to all, and five wires to the y coordinate. There is no big difference to what symbols will correspond to pressing, but, just in case, it is better to “ring out” all the values ​​in the wiring to select the most convenient ones, like 1, 2, 3, 4.

Now connect the device to the board, check for performance. Making sure the system is working, go to the calibration. Open the text editor, put the drums in a row and alternately beat each. We sign the drums from left to right: green, red, yellow, blue, and the meanings of their clicks remain with us in the textbook.
Open the configuration file Guitar Hero, which lies in the depths of appdata, in the aspyr folder, and is called config.xml. The default keys are from 1 to 4 and a few more additional. We change keys in places in accordance with the location of our drums and save the file.
Launch Guitar Hero to the fanfare of the intro videos, and ... it works!
Budget: - wooden shield, 120r - mats, 240r - lining for a spatula, 600r - glue, 50p - keyboard from bins Total: 1010r
The result was an almost full-featured controller, however, it was enough to play its functions. The goal, oddly enough, justified the means, overpowered by the joy of being able to “knock on something”. A serious share of the budget are lining, and if you repeat something like that, it would be better to replace them with a spring with two contacts.
