Best audio for your pinball machine
Today I’ve updated the repository on github https://github.com/sker65/tiltaudio-extensions that contains some examples, how TILT!Audio board can be extended by adding addtional hardware / mods for your game. The principle is always the same: take an arduino mini pro program it with some little sketch connect i2c bus from tiltaudio board to extension write some support … Continue reading “Github repo with extensions examples”
This adapter simply decodes parts of the 6809 address bus: A8 – A15. More fine grained decoding is not necessary as the peripheral address mapping is done by the upper 8 bit only. So write access to 0b00111000???????? = 0x38?? will be recognized as a sound command. Looking at the bus timing of the 6809 … Continue reading “Whitestar Test Modul”
Using a Arduino mini pro as extension to a TILT!Audio board, you can easily control a shaker motor via pwm (pulse width modulation). First we need a motor driver module that is capable of driving the high current motor power. e.g. something like this: The picture is more or less self-explaining the only thing that … Continue reading “Shaker control with pwm”
