Smart LED Flashlight

How it works: The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. The Light sensing LED Flashlight is invaluable for emergencies such as power failures or blackouts. Step 1: ​The Flashlight Is Invaluable for Emergencies Such As Power Failures or Blackouts. I have assembly several Flas ...

Power over Ethernet Flashlight

The TPS2378 is an IEEE802.3at (Power over Ethernet) Powered Device controller, featuring internal pass MOSFET for loads up to 25.5W, Type 1 (a.k.a. 802.3af) compatibility and auxiliary power source support. The IC is normally used together with a DC-DC step down regulator to power a network device (the PD) from a PoE compliant switch or injector (the PSE). A proper 802.3at device requires an isolated power ...

You hold your flashlight and try to shine it on one of the other kids, without the other kids shining their lights on you. I wanted to make this game electronic. The Arduino is my first choice, but would be a bit expensive. I would need one Arduino for each player. The next clip from "Make:" gave me the idea of usin ...
