| I stripped my IR tower few days ago and draw a partial schematics out of it. TX side. There are two IR diodes connected series. Low power level feed is 100 ohm and high level is 5.6 ohms. Low range diode current is somewhere around 50 mA. I have not (...) (25 years ago, 18-Nov-99, to lugnet.robotics)
