Solderable Proto-Board


I'm no whiz with electronics, but I'm getting better. My soldering skills are rusty, too. But since getting a look at HiTechnic's upcoming solderable proto-board, I've been considering some options for what I might want to do with it.
A recent trip to my local electronics shop (ACK, Atlanta, GA) let me find some small pressure switches (similar to the Touch sensor) that are either on or off. Whereas the Touch sensor must be mounted in a static position, pointing in one direction, I'm considering purchasing a handful of these smaller switches and giving them a longer length of wire so I can place them all over a robot. If I purchase 8 of them, I can place them around the robot in the N, NE, E, SE, S, SW, W, and NW positions and only need one sensor port to monitor them.


How would you use the proto-board? I think this proto-board is really going to open up the number of hand-made/homebrew sensors, much more than we saw for the RCX. I'm curious to hear from readers about what they would like to create using the proto-board OR what they'd like other more experienced designers to work on...

Can anyone point out what is the advantage of using this board? The only good thing I see here is the nice socket, but otherwise you can just use the i2c chip and a matrix..

I could use the board to create a motor controller for driving the Technic motors from the 8287 sets.

The build-in firmware already handles A/D and digital IO assignment, sampling etc. Thus to build a sensor you don't need any programming. There are some DIO chips with direct I2C interface, but this board also has several A/D configurable (sampling time, gain etc.) using I2C protocol. I guess HiTechnic will also make an NXT-G block to give access to all ports, so even less programming knowledge will be needed....

can anyone tell me how to build a code to communicate with the prototype board using i2c with lejos NXJ? i want it to take analog signal and give digital outputs as is in the NXT-G block supplied from the manufacturer.
