I need a circuit designer
Budget: $25 – $50 USD
This is for a joke device. Ideally as compact as possible.
1. Device is turned on, does nothing while exposed to light.
2. Device is hidden in room (somewhere still exposed to ambient light).
3. When lights turn off, device waits 20 min.
4. After 20 min of darkness, device emits VERY short & loud high frequency beep.
5. Device continues to beep approx every 5 min until exposed to light which silences it.
So the idea is it’s placed in a person’s room, person turns off the lights and goes to bed, then something starts beeping. So they turn on the light to try and find what’s beeping, which makes it silent :)
