| I was looking at that this weekend. I am presently using 4 gp2d02's and am about to order 2 more. the distance on these gp2d12's is no different and I think one might have more control over the gp2d02 since you control the digital output to it (...)

| the main reason this doesn't work is the 1a supply produces too high a voltage at the actual current being drawn, resulting too high a charge rate. technically, it will work in NORMAL charge mode, but you'll be charging the battery too fast, (...)

| Hi all: The problem with using a wall wart that is NOT 12 V @ 500 mA is this: most wall warts are _not_ regulated, and they have a fairly high internal impedance. If there is no load on a "12 V" unit, the output voltage will likely be at least 18 V, (...) (25 years ago, 10-May-99, to lugnet.robotics.handyboard)

| Hi, I'm using for my base 12 v geared motors ,without load, each one drives less than 100 mA, but when stalled, the current grow to 500 mA, wich is to close to the 600 mA of L293 chips, i do not need more current, but i want to protect the L293 from (...)

| (...) I'm relying on non-handyboard experience here, but I'm going to assume that's too much. One amp is a heavy load, and although there's a 5v regulator on the circuit, I'd guess that it's not rated for 1 amp (it may just run hot) and might not be (...)
