That's what the rectifier bridges are for. (...) With the (...) (23 years ago, 7-Feb-02, to lugnet.robotics)

| | | | I've put a simple sensor interface design on Brickshelf which shows the key elements of providing a linear bi-polar connection to the RCX sensor input. (The two wire RCX connections are represented by the large circles to the right of the (...) (23 years ago, 7-Feb-02, to lugnet.robotics)

| | | | Thanks for publishing this... I have trouble locating infos on regulator "81250", I suppose it is a 5V LDO, but couldn't find manufacturer/datasheet For other curious people, datasheet of the dual shottky diode MA704 is here: (URL) the opamp here (...)

| | | | Thanks for adding that information. I had intended the schematic more as an exmaple than something that someone would run out and try to make. The parts are all surface mount parts, since I have been building and supplying this circuit enclosed in a (...) (23 years ago, 7-Feb-02, to lugnet.robotics)
