how come nobody ever wants to make their own hardware? everything i read about the arduino involves some sort of mass produced super expensive shield. what use is hardware development if it holds together like lego!
If you don't want to design & etch, perfboards aren't exactly rocket science. They look pretty OK, though obviously not as nice as a silkscreened PCB.
Hey, I like modular stuff, it's dirt cheap when you think about it, I could spend three weeks building some board soldering it together with cpu, timers, rs232 [...]
What like wireless rs232, sensors etc.

Admittedly the UART is TTL and not RS232, but that's just a quick level-shift away.I believe that Arduino "shields" differ from generic extension models in price and form-factor: the ability to build Arduino based projects like Legos appears to permit a significantly higher price. ExamplesStereo Vision: Shield-style: Buy a $5000 commercial stereo vision system - easy and guaranteed to work Module-style: Buy two $50.00 cameras and set up the system yourself Hardware-design style: Build a custom PCB and install two $2.50 CCD or CMOS cameras on itServo Controllers Shield-style: Buy a shield that breaks out unregulated voltage, ground, and signal in servo-style headers, and put the servos on that Module-style: Buy a piece of stripboard and make your own power buses Hardware-design style: Build a custom PCB with servo headers
