Hi All, That color code on inductor should read: BROWN(1), BLACK(0), GOLD, SILVER which is (1x10^0)uF => 1uF. Sorry for the confusing and we will mark that in the future. Thanks.

I would guess this means that IC needs a math co-processor, in other words, a 486 DX or higher. -- Justin Kao <jkao@bigfoot.com> <jkao@flash.net> <ICQ 5903051> (26 years ago, 28-Jul-98, to lugnet.robotics.handyboard)

HB Folks, I'm currently using the HB to interface to a Vector 2X compass. I'm using the compass in RAW slave mode, so it's different than the hardware interface that's documented on the HB web site. But I did notice that the documented interface (...) (26 years ago, 28-Jul-98, to lugnet.robotics.handyboard)

(...) If you notice, the constant is PI/2. If you add more significant digits you can even get "a/b" to become 0.5, that is twice the correct answer rather than half of it!!! The reason the bug concerns me so much is that since "a" and "b" print out (...) (26 years ago, 28-Jul-98, to lugnet.robotics.handyboard)

Greetings, I have recently gotten the free version of IC working. It was a battle and it seems that the type of host processor makes a difference. Running IC on an old IBM XT (8088) CPU produces the following error whenever a routine using floating (...) (26 years ago, 28-Jul-98, to lugnet.robotics.handyboard)

(...) <snip> I get the same results with version 3.2. Curiously, if I remove the last digit in the a = 1.570796 statement (or replace it with a zero), then I get the correct answer. I guess it has something to do with specifying too many significant (...) (26 years ago, 28-Jul-98, to lugnet.robotics.handyboard)

I figured out all of my problems were caused by using an ac-dc adaptor with the wrong voltage. What is the correct output voltage for the adaptor that should be used with the handyboard? Also, I cannot find L1, the iron core inductor. I ordered my (...) (26 years ago, 28-Jul-98, to lugnet.robotics.handyboard)
