| Building 1-1,4V battery life indicator advice - under 5$ |
| (1/1) |
| DuncanSteel:
Hello I would like to build a battery life indicator that could be hooked up to Philips oneblade, what are my realistic options? Some quick advice would be appreciated. Goal: Voltage range: 1v to 1,4V Device size preferably: 0,5 x 15 x 30mm Points of interests: 1. Did not find any already existing solutions a person could buy for this voltage range. 2. Could you recommend some components to look into? 3. Maybe use cheap arduino clone, boost converter, some LED-s & a push button? |

Sounds like a job an AA battery tester would work for. They comes in many different shapes and sizes. The cheap ones are under a buck on ebay and other such sites. |

I have been thinking & came to conclusion that all I need is a switch that will turn off the led when voltage reaches 1V. Say the led that requires 2V must light on if voltage is over 1V & not light up if voltage is 1V or below. Use Case: 1. User holds the switch & voltage is over 1V (led is on) 2. User holds the switch & voltage is below 1V (led is off) Is there any simple way to achieve this? |
