Step 7: Test the Flashlight

First, charge the batteries using a normal charger, then put them in the flashlight and push the button. If it turns on, yay! Push it again to turn it off. If it doesn't work, check it with a multimeter and/or look over the connections. Is the LED in backwards?

Now, plug the flashlight into the base, making sure you put the connector in the right way. The LED on the flashlight should come on (dimmer than normal, that was intended to save battery for when the power goes out) because the base is unplugged. Plug in the base and it should turn off. Yay, everything should be working! If this doesn't work but the flashlight does, compare your board against the schematic.
Could you post a schematic that uses normal batteries, and just uses the wall wart power to sense the presence of power, and to run the light if you want to switch it on when the power is on, I was thinking about using something like this with regular batteries for our wireless telephone base, when the power goes out it would switch to the batteries, like a mini UPS for computers, could you post a schematic?<br><br>Batman96
For that you can probably take out the voltage regulator, the resistors and diode connected to it, and the middle pin of the connector out and it should work. I'd like to see it if you make it, good luck!
Thanks, I will try it when I get a few other pressing projects done.<br><br>
funny how some of these components look like they came from thecustomsabershop.com. especially the rebel star LED and the PCB. nice idea to have these plans available.
no actually....it looks like most of the SEOUL P4 LED blade kit now that i think about it. the switch looks like its from radio shack since teh kit only has a momentary switch.
I got the LED (and pretty much everything else) from Mouser, I could look up the model number if you want. But you're right, the switch is leftover from the days when I would still shop at Radioshack :-)
love how the chargeing base is a night light you need to work on a case
Thanks! Personally I don't think it needs a case, but I'm sure a lot of people would. If you make one, please send pictures!
