Hi, this seems to be a very good idea for a new RCX sensor. Reading the Sharp data sheets for their infrared distance sensors I want to write some facts about. They have 4 different sensors for measuring distances from 10 to 80 cm. The differences (...) (24 years ago, 3-Oct-00, to lugnet.robotics.rcx)

(...) Ralf, If I remember correctly, these sensors draw about 30 mA, which is the limit for a powered sensor for the RCX. You may need to add an additional battery to supply the current....

Ooh, you're right. This seems to be too much for battery powered models. Has anybody a better idea? I want to have a sensor with gives a linear (?) signal corresponding to a distance. For an 1-bit boolean signal I saw a plan in elektor 9/2000 (...) (24 years ago, 3-Oct-00, to lugnet.robotics.rcx)

Hey, my GP2D12 just showed up. I ordered it from Acroname. It comes with a nice little booklet with details on how to rig it, and it even has some Handyboard code and interface info. I have test equipment in my lab too. I'll plug it into a power (...) (24 years ago, 4-Oct-00, to lugnet.robotics.rcx)
