I have a projection clock (it shines the time in big numbers on the wall opposite the bed) that I bought about 10 years ago on eBay for maybe $10. I've been fortunate in that for the last 30 years or so my job did not require me to be at work at any specific time, and now I'm retired and I don't have to be anywhere at any specific time. I don't know if the alarm even works, and the sound quality of the radio is bad beyond description so I don't ever use it.

On the rare occasions that I do have an appointment I just tell myself to wake up at a certain time, and I do.
