  Re: SHARP new product
 
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 (...)

  Re: charger
 
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, (...)

  Re: charger
 
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)
 
  Measuring motors current
 
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 (...)

  Re: charger
 
(...) 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 (...)

  SHARP new product
 
Hello everyone, Sharp recently release the new GP2D12 (General Purpose Distance Measuring Sensors). Which performs same as the GP2D02. The new product have only 3 pins - Vo, Gnd, and 5V. Vo is an analog output, which means you can use it on any (...) (25 years ago, 9-May-99, to lugnet.robotics.handyboard)
 
  Re: charger
 
(...) In short, No. The charging cicuitry on the HB (especially the zap mode) is designed for a 500ma supply. People have had problems with 1 amp ones. Best, Duncan (25 years ago, 9-May-99, to lugnet.robotics.handyboard)
 
  Re: Batteries
 
(...) Umm, not sure what you mean by "a current rating of 1A or more". Do you mean 1Ah ? It's certainly alright to use a 9.6v battery with a *capacity* of 1Ah or more... Cheers, Duncan (25 years ago, 9-May-99, to lugnet.robotics.handyboard)
 
  charger
 
I have an old 'wall wart' lying around. It has a rating of (12 vdc 1 amp output). i was wondering if i can use it on the handy board. the specs i read about the handy board call for a 12v 500mAmp output. any response would be appreciated.

  Batteries
 
Hi Guys, I was wondering if is it safe to use a 9.6V battery pack with a current rating of 1A or more? (25 years ago, 9-May-99, to lugnet.robotics.handyboard)
