from my experience it really depends on the application, if you are working on a walker it usually takes a minimum of 1:12 for most of mine, but i don't know waht you are doing. mike "rubbing the weekend out of his eyes" fusion (25 years ago, 22-Jan-01, to lugnet.robotics.rcx, lugnet.robotics)

That was not a general statement. The X10's quality is poor for indoor lighting. There are several better wireless digital cameras out there that is far better than the X10, but it costs a lot more. Cant beat the $50 I paid for the X10 via ebay (...) (25 years ago, 22-Jan-01, to lugnet.robotics)

The Lego Cam's quality is much better than the X10 as I have both. The X10 was designed for outdoor only and as such needs a lot of light otherwise the image is dark. The Lego Cam is the same as the quickcam. However, the wireless ability of the X10 (...) (25 years ago, 22-Jan-01, to lugnet.robotics)
