I have an oven and a deep fryer at home. Both has the same type of digital timer in it. The timer has a two digit 7 segment display and two buttons with one drawback. It only beep when the time elapsed but unable to switch of the device.
I realized that I need a timer like this for various purposes with switching capability.
Here are the planed usage:
– Control the deep fryer above
– Small, desktop timer (it may requires LCD instead of LED display because of the battery operation)
– Control my (planed) UV lightbox what will used for PCB solder mask developing
– Soldering station watchdog
