Jack,

Having worked in aerospace for thirty years I can tell you nothing is easy or cheap when it comes to space type projects. Even the simple projects require a lot of analysis and testing just...

Parallax did provide some BASIC Stamps to the group. The motorcycle used some Stamps and did qualify for the final race. I think he had the best setup as far as cost goes. All those other vehicles...

The CO sensor does require you to set the alarm limit from some suitable CO source. A butane hair curler would be a good source. The sensor itself does change with time and needs to be checked. The...

Use a DS2760 or buy the Parallax thermocouple sensor. You can detect +-64 mv.

Something tells me this will be the best show of shows. I'll watch the video of this first history making Propeller expo by the best innovators.

Please be aware that you are connecting the solenoid valve on the hot side. If the solenoid low(or netural)·side lead is grounded the valve will be actuated. Sometimes droping a metal wrench in the...

Maybe a change is needed to advance the "state of the art". Something besides C and C++ or a new modified C+++.

We are lucky to have a BASIC Stamp and a Propeller Chip. I am not sure if the potty/board room of America could stand for someone spending eight years on a processor development effort. I suspect...

I am sure you will see connections (both electrical and software)·between the BASIC Stamp and the Propeller in the future. We will probably see something like a master and slave arrangement....

Phil and all,

Please review what EDN says recently about multiprocessor architectures. They say this is tough thing for you guys to do - interesting.

The way to do this is to use the parallel port (printer port) as a switching device on a serial port. This was done on a Parallax product known as PCSTAMPII. I think you can connect eight(8) BASIC...
