well all the circuitry is, is a pic 12F675, an IR LED and driving transistor
the IR LED is driven at 100ma at 62.5% duty cycle [30ma average] and thats it
when the PIC is not in use i plan on putting it to sleep which is 1nA @ 2V
operating current will be while it transmits the signal which is for around 18ms plus some calculation time call it 22ms with operational current 100uA @ 1mhz [im running it at 4mhz, 1mhz instruction cycle so roughly 400uA?].
so when sending IR data its around 400uA PIC + 30mA IR LED + 3mA transistor Base = 33.4 mA
and when in standby 2nA call it.
so not much
