Just started to learn how to use my new HB. In going through the IC manual I could not find any routines for writing to the serial port. Does anybody have a good example on how to write "hello world" to the serial port, and have the attached (...) (25 years ago, 29-Jul-99, to lugnet.robotics.handyboard)

Hi all, Seeing notes about the sub and all, I thought I shall share some info. I know this list is purely for HB enthusiasts and forgive me if this does not interest you. The reason I got involved in HB was when I planned to use HB for a Aerial (...) (25 years ago, 28-Jul-99, to lugnet.robotics.handyboard)

Recently , i am trying to use HB as the controller for a Remote control project .

There is a whole community of Radio Control submariners who have extensive experience that you could make use of. If you want it to act like a true submarine with diving planes etc. you should definitely use their knowledge base. It is much harder (...) (25 years ago, 28-Jul-99, to lugnet.robotics.handyboard)

(...) Yes. You missed the "with a hole at the bottom connected to the water" which means that water comes in as you move the air to the reservoir. And this means reducing the effective volume of the submersible but keeping its weight. Just the same (...) (25 years ago, 28-Jul-99, to lugnet.robotics.handyboard)

Hi! I planned to build a sub myself about two years ago but couldn't find the time to build it. What I have to offer are some thoughts. Fortunately a submersible needs lots of ballast, so you can stuff it with lots of batteries and gear. So my plan (...) (25 years ago, 28-Jul-99, to lugnet.robotics.handyboard)

Hi - We are building a submersible robot. For maintaning the depth we need a ballast system, we are planning to use a canister of compressed air with some electronnically controlled valves. In addition we are planning to use a depth sensor, Pressure (...) (25 years ago, 28-Jul-99, to lugnet.robotics.handyboard)

| | Re: Interfacing handyboard with Basic Stamp2
|

Hi, You can use the SPI interface and have the BS2 as a master. The BS2 then defines the clockspeed, because the slowest speed you can select on the 6811 is probably to high for the BS2. It is very simple to use this interface. See the "pink book" (...) (25 years ago, 27-Jul-99, to lugnet.robotics.handyboard)

Greetings All! I was wondering if anybody out there knows of any good, relatively inexpensive, (<$350) Voice recognition hardware that is relatively easily interfaced to the handy board? Thank you very much. -Ryan Meuth (25 years ago, 26-Jul-99, to lugnet.robotics.handyboard)

I remember someone saying a few months ago that if you use a 12 V battery with the HB, then the HB's built-in charging circuit won't work properly, and that 12 V batteries can initially deliver up to about 14 V, which wouldn't be very kind to (...)

When I screwing the board into the case the lead eventually pierced one of the wires going to my Nicad pac. My board would (...) (25 years ago, 25-Jul-99, to lugnet.robotics.handyboard)
