| (...) i would like to encourage you to publish your knowlegde, as there is - as far, as i know - no other source of information about that subject in the internet today. So, you would be the first! I am very interested in seeing your diagrams. (...) (20 years ago, 18-Dec-04, to lugnet.robotics)

I cannot guarantee accuracy as this is my own interpretation of the circuit of my own IR Transceiver, using data from reference books and tracing the circuit myself, so I might have made (...)

| (...) Thanks for this one, Mark! For the sake of completeness, some data on devices used. Note: as there are "collisions" in SMD device names, these are only "very probable"... 1Kp: (URL) 3Kp: (URL) are NPN and PNP general purpose transistor. A4p: (...)

| (...) I can verify the data on all but the zener and 6Cp transistor. I intended to put it in a text file with the diagram, but I'll add it to the diagram instead. The 1Kp and 3Kp transistors have equivalents of BC548B and BC558B, which are common (...) (20 years ago, 28-Dec-04, to lugnet.robotics.rcx, FTX)
