Is anyone else using the Mobile Robot Development Kit from the KISS Institute? I was curious to see how other people had mounted the break beam sensors which come in the kit onto LEGO pieces. I've been having a lot of trouble getting them aligned (...) (25 years ago, 25-Feb-00, to lugnet.robotics.handyboard)

(...) you are confusing mAh capacity (the amount of energy stored in the battery) with how fast the batt can deliver the power. the two are not the same. the fuse is in the design because nicad cells can deliver a *DANGEROUS* amount of power if (...)

(...) CAVEAT: I'm probably full of it, but here goes.... My understanding is that a 12 V NiCd battery pack would not damage the HB, since the HB can handle up to 12 V. The problem is that in order to charge a 9.6 V battery pack, the HB built in (...) (25 years ago, 24-Feb-00, to lugnet.robotics.handyboard)

(...) The self-resetting thermal fuse that's part of the HB ought to be just fine (see item F1 on the HB schematics). I think that if you use a 9.6 V NiCd battery pack with less than a couple thousand mAH capacity, you probably have nothing to worry (...) (25 years ago, 24-Feb-00, to lugnet.robotics.handyboard)

Is there a general guide to what fuse I should have with a certian current? Please excuse some of this if it doesn't make sense, I am learning a lot of electrical concepts as I go... Would the internal resistance of the battery be shown if I measure (...) (25 years ago, 24-Feb-00, to lugnet.robotics.handyboard)

(...) Yes. Exactly the right point. The two different things to woory about, are the mA/Hr rateing of the battery (which tells you how long a particular current can be delivered), and the _internal resistance_ of the battery, which limits the (...)

It means you can get this current over a time of one hour. (...) (25 years ago, 24-Feb-00, to lugnet.robotics.handyboard)
