Data logger clock and array

[skimask]

To power up the pic I was thinking to use TO-92 0.5% LDO and 1 or 2 small capacitors.

You should be able to drive a PIC directly from one LiPo, no regulators need.

I'm not going to use voltage reference to keep it simple and ADC probably should work within 1%-3% accurate.

There's a few PICs out there that have a built-in .6v reference which you could 'reference against'.

As you can see 1 PDIP microchip, 1 LDO, 1-2 capacitors and just connector glued and soldered directly to microchip.

If you think it'll run, go with it... I don't think it'll run and last, but that's just me.

Using software rs232 I don’t need Max232 so I can just use serial female connector with 2 resistors and connect it directly to microchip whenever I need to upload the data.

Same thing with the USB, the connector, 2 wires to the PIC (D+/D-), an extra cap, and the right firmware.
