    NiHaoMike got a reaction from spirilis in Where would be a C2000 useful?   
    Apart from motor drives, digital power supply control is a big use case. Also useful to drive haptic feedback devices ("vibrators") for gaming purposes. I'm actually working one one of those, albeit with a dsPIC processor.
     
    BTW, if you own a high performance PC, there's a decent chance there's at least one C2000 in it for the cooling fan drive. More on DIY hobby electronics, a closely related application would be drones and other hobby aircraft.

    NiHaoMike got a reaction from tripwire in OpenDAC HD: an open hardware HD audio DAC   
    The volume control is a rotary encoder on the front panel. The motor was left in simply because it was too difficult to remove. Once the top cover is screwed on, the entire unit is quite well shielded. That "freestyle" construction method was good enough for Jim Williams.
    There are more pictures on the Github, including schematics, output waveform comparisons, and even a picture of my best friend and I holding the unit.

    I recently got a renewed interest in HD audio and decided to work with my best friend on an open source HD DAC. I selected MSP430 since it's easy to work with using Energia and an Arduino is overkill for what I'm using it for. (I normally use PICs, but then my friend, who is new to embedded programming, would have a hard time contributing.)
