Hi, You can try to remove the buzzer on the board, then test beep() function. If the board does not freeze up, that means there is a problem on the buzzer itself.

Please help me. All the commands from IC to HB work fine.e.g. analog test, digital test, printf to LCD, etc. But, when I write the command "beep();" the board makes a continuous noise and freezes up.

Replacement battery options are listed on the HB FAQ, at: (URL) don't you get the 1000 mAh packs from Radio Shack? That would give you 2x the run time of the 500 mAh packs. Take longer to charge, but would require no other board mods. Fred (...) (24 years ago, 12-Oct-02, to lugnet.robotics.handyboard)

(...) Well, first of all, injection moulding may not have to be the only option. Thermoforming may be another alternative that to my understanding does not carry anywhere near the initial expense as injection moulding. Secondly, what might make it (...)

A case as you describe it would be nice. To me it's largely a cost issue. Custom plastic is expensive to set up -- thousands of dollars for an injection mold. Anyone care to open-source a design? That would be a start :-). Fred (...) (24 years ago, 9-Oct-02, to lugnet.robotics.handyboard)
