davebranton 11 Posted February 13, 2013 Share Posted February 13, 2013 Hi, Since I have two of the MSP430's left over from the two launchpads I bought, I though I'd breathe new life and fun into the now-obsolete PlayStation one light guns. Using an MS430, an 8-pin DAC in a DIP package (an MCP4911) and an LM386 for amplification. Thus far, the basic plan is: Run the 430 of two AAs directly Use a DC converter (TPS61041) to step this up to 5 volts ish for the LM386, Use a FET to turn this 5v side off when in sleep mode Use the 430 to generate some incredibly awesome laser gun sound... ..and actually a cool reloading (yes I know laser guns don't reload) sound too, because the gun has these cool buttons on the sides too. Steps one and two are no problem, and talking to the DAC is over SPI so that should be straightforwards too. This should be a fun project, but I've never done any synthesis before. I guess I could put an SD card in there and use digital samples, but I'd like to create the sounds generatively. Has anyone got any ideas? I've heard of FM synthesis, but it doesn't sound all that flash to me. Also, I've come across this rather amazing thing, which might also be a possibility if I could get the numbers right: http://countercomplex.blogspot.co.nz/2011/10/algorithmic-symphonies-from-one-line-of.html And just to add a picture too, here's the surface-mount DC converter soldered onto a bit of perfboard next to the schottky diode.
