He’s using an everyday LED as a detector diode and an internal pull-up resistor in the ATtiny13 for the bias voltage. The antenna runs off the LED’s anode. To make it sensitive enough ...

[Steel 9] was looking around for a LED strobe light for reasons unknown ... not even a single current limiting resistor. A masterstroke of engineering, surely, The added circuitry consists ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum ...
