(...) I strongly suspect this is a myth. A transistor is a transistor is a transistor. They all require biasing in order to function properly and that requires power. Mind you, even so-called passive devices must either generate a voltage or have a (...) (24 years ago, 31-Mar-01, to lugnet.robotics)

| | Solar Capacitor
|
|
I have been playing with a couple of Lego solar panels and the Capacitors. (URL) label on the capacitor claims a value of 1 farad. Is this value possible in such a small component? I always thought a 1 farad capacitor would need a huge plate area. I (...) (24 years ago, 31-Mar-01, to lugnet.robotics)

|

(...) Transformers do NOT convert AC to DC. They only convert AC to AC. The DC conversion is performed by four diodes in the RIS1.0. Maximum input is rated at 12V AC or DC (the diodes will take care of the polarity for DC inputs) although the (...) (24 years ago, 1-Apr-01, to lugnet.robotics)

(...) The RIS 1.0 can be run from either 12VAC or 12VDC. In either case an internal bridge rectifier supplies the internal circuitry with the proper polarity. Internal power is supplied through an LM2936M 5V regulator (maximum input of 45V BTW) The (...) (24 years ago, 1-Apr-01, to lugnet.robotics)

(...) Actually you don't need LegOS, any input set to raw mode with the LEGO firmware will do fine. This is because even in passive mode there is a pull up of 10k to 5V, and in fact the LED is glowing dimly in this mode. Just tried it, I can get raw (...)
