Once of the things I want to do with the Wi-Fi Hi-Fi is have sound-reactive lights. I burned out two sound-reactive t-shirt modules using a 5v wall wart, even though in theory that should have worked just fine. Some wires got crossed and apparently shorted stuff out, but that's because of the way the original LEDs were wired. So today at Fry's, I picked up a
Velleman's Sound-To-Light kit. I know Velleman makes a lot of fun soldering kits, so for $5 I decided to give it a try.
It was fun putting it together, and definitely good soldering practice. I did one hack, installing wires in place of the LEDs so I could hook them up to the existing lights in the radio. One issue, though - the system uses 9v, and I have 5v running in the radio. I hooked it up to a 5v test wart I have, and nothing worked. I then used a 9v battery and it worked perfectly. I really don't want to use a battery, nor do I want to add another wall wart inside. Anyone have any suggestions? If I swapped out a cap or resistor(s), do you think I could get it working with 5v? Here's a link to the
manualthat shows the components used.]
BTW, these kits are pretty sweet. I might pick up another one just for kicks.
