Made a simple auto-off circuit with a 555 timer and some caps and resistors. Carved the housing out of a small log and hid the electronics inside so I can press a hidden button and trigger a UV LED to turn on and light up a glow-in-the-dark mushroom. After 5 minutes the LED shuts off. Mushroom makes glowy nightlight for several hours. ^_^
