I loved the Aurora LED Color Light Cube Chromatography Glass Clock Kit that I put together not long ago, apart from one 'feature'. That feature is the beep it emits on the hour. The beep is not subtle by far and the first time I heard it I thought an alarm went off somewhere in my apartment. There is a way to switch it off of course but my clock is plugged into a USB hub connected to my laptop so whenever I disconnect that the clock loses power and when connected again the beep is back (yep that setting is not saved).

The clock kit can be purchased here by the way.

I decided to do something about the loud noise. The speaker had to go and I wanted to see if I could replace it with a LED. Turns out that you can drop a LED right in place of the speaker and it works without any issues. Here's the end result...

I picked a blue LED simply because it was already on my desk. The anode (positive, long leg) side is soldered in on the left closer to the minutes RGB LED. I bent the LED pins to shape so it would fit flush with the PCB.
