I am new to the whole basic stamp thing and have some questions. Here
goes.
I would like to build a multi channel(4) wireless dimmer unit that
will operate on 12v dc. The transmitter will be driven by a lighting
board.
Questions-Will the stamp have a fast enough response time to be used
like a wired dimmer(aka real time)?
-Is there a transmiter/reciever that works best with a basic stamp?
-There will need to be a converter of some sort between the lighting
board and the transmitter? The board uses DMX but I could get an
analoge(0-10v) converter.
-Does anyone know of a transistor circuit that can be used as a
dimmer in conjunction with a stamp?
I know this is alot to ask but I'd rather not re-invent the wheel if
someone already has done something similar.
From everything I have discovered so far, the basic stamp seems to be
extremly versitile and excactly what I need.

section. They have transmitters, receivers, and transcievers for cheap and
they will do the trick nicely. I am using the transciever for a two data
link to a R/C controlled submarine and they work great.. With these RF
devices you can have one transmitter and as many receivers as you want and
simply make each one have a unique address and then it will only respond to
commands sent to it's address..

wouldn't be as fun as doing it yourself! I know there are some DMX dongles
that connect to a serial port for either transmitting or receiving. They
come with software to work with the Palm Pilot. Perhaps it would be easy to
interface with them.
E-mail me privately and I can look up the info for you (I don't read the
Stamp maillist very much anymore)

These can be made to work very simply with Stamps if your application does
not have to be very precise, such as a typical hobby app. In some other
applications this may be OK.
Most RF com specs require some kind of data validation and re-transmission,
as well as determination on what to do when bad data is received. This
generally calls for a closed loop, or at least 1/2 duplex operation. The
Stamps can do this, but at their baud rates it can be difficult to implement
all that is needed to satisfy a real specification at any speed. Interfacing
to a PC will make your process wait an unknown amount of time for the PC -
which makes your handshaking require a bit more effort, and slows the
process down considerably more.
My point is that for a commercial application, don't expect to work out all
the details overnight.
On the other hand, if you only need to repeatedly send serial data from a
stamp via an RF link continuously, hoping that it will be received
correctly, this truly is fairly simple and can be done without much effort
if an off-the-shelf TX/RX pair is used.
