I am looking for a technical collaborator to work on a not-for-profit project involving a multiplexed robot for classroom use. Up to "n" pupils using RPIs (or whatever) may share switched access to the robot. (Where "n" is probably 32!)

The project involves a lot more than the robot but it is the hardware side I need help with. The robot nuts and bolts have been designed and we are arranging manufacture.

The current controller PCB side has reached prototype stage using USB as a connection.

The next stage is to go wireless and I want to keep the costs down - so I don't want to use an off-the-shelf plug-in board, I want to put whatever ICs are required directly onto the controller board which uses a pretty meaty Atmel ATMega256A3U.

I am open to suggestions about the technology to be used - Bluetooth springs to mind but Bluetooth gadgets do not pair at lightening speed - to say the least!

I had considered using the ICs in wireless mice/keyboards but there is probably something better or more appropriate. Broadcom probably make something suitable so if any of the RPi team read this ....

We have in-house programming skills so the software side is no problem - though we don't want to reinvent the wheel and write our own stack. We just want a simple, fairly fast (but not OTT), data link between the pupil's PC and the controller card. We have no problem developing our own comms protocol and command set if necessary.

Anyone with RF experience keen to help? No money in it (except expenses) but lots of brownie points.

Wow, that's a complex spam bot. If it weren't for the signature, I'd have thought it was a real post, interrupting my thread.

Dr. Sherman is up.

update?

sorry! got caught up over the weeknd. i'm on it rght now

..annnnd done!

so which list are we going by? the one posted in the thread or on the sync website?
and why aren't we just writing in there? (just curious)

anyhoo, i rolled a 6, which would either be Adoom, or me again

we're going by the sync list. http://sync.in/9TyBrqqzal
people can still join in. just write yourself down there.

and we should really like, make a fb group or something so we can coordinate more easily.

cool. i rolled again, got a 4.

MAZ is up!

sent him a PM w/ the file

CAN WE WRITE IN PREVIOUS SECTIONS? AND ANSWER QUESTIONS?

don't write in previous sections, but I don't know. be creative. guess we could start quoting eachother, but it would strangle the book imho.
*discussion open*

what happened?

very sorry, i talked to alexa via FB. i have the book, got caught up in the facts of life. will write and pass on today i promise!

No problem. I've been busy with life stuff, as well. I was just wondering if the books was forgotten and lost already, haha.

UP!
