Food or game time flasher
thingiverse
My son has his room two floors up and when it is dinner time I don't like to shout for him. He also wears a headphone so something visible makes more sense. This is a flashlight on battery power controllable by remote control (Blynk in my case). So I included an esp8266, recharge circuit, step-up converter for flashlight, step-down converter for charger. It houses some electronic components on a 'houder' that clicks on the rest. So making a holder for other electronics is easy. No need to redesign the rest. Th eused batteries are of type 18650 and slide into the rounds. The flashing light is from AliExpress: - https://www.aliexpress.com/item/32993941089.html?spm=a2g0s.9042311.0.0.45b24c4dbFfPnD
