Ro-bot-x mentioned using the I2C bus for powering the electronics. that might not be the best if you get 6 or 8 modules we might over load the bus power. Just depends on where it is supplied from. If we separate it and power it desperately on the main master board then it would be ok. Just something to watch for.
No offense but I strongly suggest you guys stay away from this posting of ideas. Maybe every participant could log on to skype or some other program from 6 to 7, 7 to 8 o'clock and talk about it. With the posts, what you do in 5 days can take less than 1 hour because when you post it takes time for it to get answered. Just a suggestion. You guys could decide what time you want to log in, maybe from 6-9 PM will be the operating time, and people could log in at any time they can from 6-9. Then a couple of people could do a report on what was achieved every day (summary), so people who couldn't make it are in the flow of things.
I'm not sure if it matters which one. We could make a PIC and an AVR version of a main board. Indeed we could make a PIC and an AVR version of everyboard, but it doesn't matter if we mix and match. You could have a PIC main board attached to an AVR stepper controller etc.Also, if we allow people to create boards with either, then it will be more accessible to people who only have experience/equipment with one type.
the reason i like plastic cases is because I had this really nice PIC programmer I just bought and then it fell down i bought a new pic programmer with plastic casing and I have dropped it multiple times ( on concrete , lol ) and its still working like new!Im not talking about a huge plastic casing , just enough casing to cover the PCB to protect it from damage.
The modules are fixed inside or on top of a robot... plastic casing around each module seperatly is useless in most cases.
We need to specify the placement of the I2C connectors!
I think we should make each module with mounting holes for a case if someone needs it.Also, do you think it is feasible / better for every module to have standard dimensions, that would make life easy.
well first we need to decide what microcontroller we are using.
