    Hi - my 1 year old table top freezer causes audible clicks on my (good quality) audio equipment every 15-30 minutes as it turns on/off.

    LED Strip audio driver

    Hi, I made a comparison of Led drivers that react to music. I wasn't satisfied with the commercial ones, so the middle one is designed by myself. The self-made middle one reacts to audio frequency and volume. The other ones react to volume only. What do you think?

    Speaker/Amp Power Supply

    I'm not sure which would be best suited, a 12V 2A or 12V 3A Power Supply to power a 15W Amplifier (2*15W Outputs) and a Bluetooth Module. I thought that since the amp is using around 30W output (2*15), it would need about 12V 3A in alone (probably a little under that), but the bluetooth module...
