  • Mike,

    Thank you for the quick response! Goin rechargeable!


  • What are the power requirements for this? I built a project with one of these a Pro Micro - 5V/16MHz and ONE LED. I am powering it with a bank of 4 AA batteries.

    The LED goes on when I am on the phone so the LED is on about 30 minutes a day.

    The batteries lasted one week. Is this normal?

No public wish lists :(
