Mansour Behabadi hacks the multi-functional LÖTTORP (or KLOCKIS) clock/ thermometer/ alarm/ timer to provide a visual beep instead of a sound.
Visual notifications may be preferred, especially if you work in loud environments or have headphones on.
Using the clock’s backlight, Mansour hooked the buzzer straight up to the backlight. See it beep in this video.
