I think this one comment hits the nail on the head. These parts are components,
not ready to go sensors. If you'd be happy to pay $1.50 for an IRPD, you can buy
them from most major component resellers. Go browse what digikey sell as
sensors.
The thing is, most Mindstorms users are not electronics engineers. Or they don't
want to be. They want the details taken care of, so when you say "its an RCX
compatible ultrasonic sensor" you mean to imply it connects to the RCX sensor
port and the software on the inside of the RCX can use the readings.
There is absolutely nothing stopping anyone buying bare electronic parts and
sticking them in their own bricks if they want.
But there is a big gap between a bare IRPD costing $1.50 with four wires hanging
out the end and a blue brick with a Lego compatible wire hanging out the end
which works with the RCX. Its about $35.
If you can build $1.50 sensor into a 4c brick and sell the result for $5, the
world of Mindstorms users will beat a path to your door. I'll admit that I do
not know how to do that. I wish I did.
