(...) 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 (...)

Scott, I see this set frequently on eBay. There are six there now. Just search for "8880". I got two that way. It's a great set, though I feel that the suspension and joints to transmit driving power to the wheels are rather inflexible. Most of the (...) (24 years ago, 2-Apr-01, to lugnet.robotics)

Hello I've built a line follower which is quite fast (approx 4 secs per lap on the testpad). It consists of two motors, each powering a 2/3 geared large wheel. Two light sensors are attached to the front pivot wheel. The distance between the sensors (...) (24 years ago, 2-Apr-01, to lugnet.robotics)
