A PIC that runs down to 1V? I don't think I've ever seen one.

You'll need a boost converter if you want to do that.

The i/p versions are DIP and the easiest to work with for experimenting.
A programmer is how you get your program "burnt" on to the PIC. it's a device that goes between your computer and the PIC. It handles all the special signals, voltages and timing required to program a microcontroller.
There are many kinds from homebuilt $$ to professional $$$.

Edit: as Hero999 mentioned you'll need at least a 2.5V power supply, a couple of AA batteries will do nicely.

A Microchip PICStart Plus Development Programmer (old, slow & expensive)

okay do you suggest any better chips for the 1.5 volt tracking device

Sure build this discrete version

I suggested that on the last page.

kartulisupp,
It's hard luck I'm afraid, the only way of building this is to make a discrere version of the LM3903 as it's no longer made.
