a CSS555 would be much better for consumption.
This new receiver shuts off after 4 hours of no use.
As said, little output current (pin3) available at low (battery) voltages.Only the 'discharge' pin of a cmos 555 can sink enough current to drive/modulate an IR LED at low supply voltages. Example attached is a continious mode 5meter curling game 'beambreak' ~38kHz IR transmitter I designed some time ago. Works on 2x AA for a looong time. LED/resistor to the left is a battery indicator, and is not needed to function.Leo..
Although, after reading today; I ordered up a few 4541's they seemed more like something that was usable for the long duration.
Understood. Bloody nuisance compulsary power savings "feature"
My Samsung TV also does that e.g. when I'm watching a long movie."Press a button within 1 minute, otherwise I will enter standby" Grrrr.
Can't you use e.g. a Nano and a 5volt phone charger with micro-USB lead.
A phone charger runs on fumes. Batteries are expensive
Sleep the Nano if you want to, or use it also for something else e.g. temp display or fancy TV background lighting.
What frustrates me the most is there is an option in setup to disable the feature; but it doesn't work... and
You seem tech savvy, might like to consider one of these.Use sleep mode then de solder the usb and led once it's working
