 | | 1.5/2.0 infrared problem
|
| Hi I've got two RCX: a 1.5 and 2.0 version. I' ve got a problem with IR emiter/reicever. The 1.5 version seems to be more sensitive to reflected infrared and its good to use ! But the 2.0 RCX is less sensitive and for example doesn't receive (...) (22 years ago, 15-Mar-03, to lugnet.robotics.rcx)

| | RCX 2.0 Difference
|
| I have got both an RCX1.0 and RCX2.0 unit. The RCX2.0 has a much less sensitive IR port. I would use the remote control to send messages and start and stop programs and to trigger motors. With the RCX1.0 the remote could be pointed at the unit and (...) (23 years ago, 7-Aug-01, to lugnet.robotics.rcx)

| | Bluetooth
|
| I’ve just started a little project of building an interface between a RCX and a Bluetooth. For power supply I’m thinking of using one of the outputs on the RCX and for communication I’ll use the IR port(2400-baud), similar to Mindsensors´s RCX to (...)
