Hi all I mailed the list a few weeks back about implementing a colour sensor. someone suggested using three photo resistors with red, green and blue filters over it. I have built the sensor with four photo resitors, three with the different filters (...) (25 years ago, 26-Feb-00, to lugnet.robotics.handyboard)

Dear HB, I am trying to convert an anolog voltage from a thermocoupler to a digital value and display it on the LCD. I thought this could be accomplished by changing the high reference voltage V(rh) from the default 5V to 600mV to get the max (...) (25 years ago, 26-Feb-00, to lugnet.robotics.handyboard)

John, The 1 KHz system interrupt is set up in the IC pcode, which you are not loading. Furthermore, the bootloader for the Handy Board is loaded into the first 255 bytes of on-chip RAM when you load pcode, and disappears on reset. It can't cause you (...)

Hi John, Using compiled programs with the Handyboard is not difficult, the steps used to download a compiled program are exactly the same as downloading the "pcoder" file in the Handyboard documentation. The compiled program is used instead of the (...) (25 years ago, 25-Feb-00, to lugnet.robotics.handyboard)

Dear Sir or Madam, Let me preface this email by saying that I am an extreme novice at programming microprocessors so please try not to laugh to hard at my questions. I recently started an electronics project for which I chose to use the handy board (...) (25 years ago, 25-Feb-00, to lugnet.robotics.handyboard)

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)
