Progress Update

Saturday, April 23, 2005 at 07:26PM

Today i started creating the schematic in Eagle. I placed an sample order from Microchip to get some PIC16F4550.

Parts i’m currently looking for:
- A voltage regulator which will boost the output of a 3V lithium coin to 3.3V and will automatically disable if the device is connected to the computer via USB. If connected to USB then the computer will supply the 3.3V. Thefore, the voltage regulator should ideally have an active low enable pin.

Before you do anything, think. If you do something to try and impress someone, to be loved, accepted or even to get someone's attention, stop and think. So many people are busy trying to create an image, they die in the process.
