deSilva is right again.
No-one is going to notice an announcement about a fabulous development lost in a huge thread on SPIN vs. Assembly.
I asked a question about A/D over in http://forums.parallax.com/forums/default.aspx?f=25&p=3&m=220153.
And to my complete pleasure there are some goodies in the works!

"See attached a prelim design of our PropBus System.
The motorship PCB is only slightly larger than a std business card.
The mother PCB has 3.3V + 5V connectors on it.
Also a connector with power and the I2C signals..
plus a RCA connector for Video output ( debugging)
24 I/O lines are broken into 3 blocks of 8 I/O
Via ribbon cable IDC headers people can add their own little PCB's
Initially we will supply 3 I/O cards for simple prototyping on the bench.
These little cards have 8 inputs Switches and 8 leds on it.
So our previously posted "Handy in/out schematic a few day's ago.
So the system is open and can be added to as you wish..
Commports RS485 etc etc etc...Ethernet ( how many i/o needed for that ??)
If anybody has any ideas or wants to develop their own cool add ons
let me know would love to see what can be done.
We seem to run into people wanting various options so it is hard
to pin it down what is needed .. that's why this simple platform to get started..
Have not as yet submitted the Gerbers files as yet still tossing and turning on the final
version .."
I'm looking for a way to get an instrument amplifier (AD624AD) talking to a nice A/D chip... for measuring ED.
I really like sockets... but I'm now convinced that I can solder without putting my eye out[noparse]:)[/noparse]
One thing I would like you guys consider is how to socket/adapt the really tiny stuff (SMP etc)
I found a really exciting 24 bit A/D chip but you need a microscope to see it. I think there is a real need for just that... "chips on dips."
The market would go well beyond Parallax. I wouldn't be opposed to easy baking the little critters on a tiny board built with just that one component and some pinouts.

This sounds a lot like Brian's SpinStudio...
Why don't you adopt a similar standard so that parts are interchangeable?

Okay here it is .. since you insist.
Pretty well done now .. just submited it to the local PCB maker.
Need to get if made in one panel and the individual smaller PCB's cut out
to get it for a realistic price .. volume is going to be our main issue.
The overal view of the whole panel is 175 by 100MM.
To start with it is really aimed at getting going with an awesome chip.
My initial target market will be educational + people wanting to explore the Propeller.
Each system comprises of the following items
1 off motherboard PCB·· (98 * 52 MM )
··· Loaded with a ProP Dip + eeprom + 5MHZ crystal
··· Onboard specs·>> 5VDC + 3.3VDC present· (3.3VDC routed to all IDC headers)
··· Separate 5VDC connector to external cards + separate 3.3VDC con as well.
··· Separate I2C·· bus· 4 way header connector.
··· Video out to RCA plug
····Connection to a Propeller PLUG for Programming the Propeller
··· Power to the board via a 2 way screw terminal·· 9VDC reverse polarity protected.
3· off··· Input /output cards. ( connects via a 10 way ribbon cable )
···········each card as you can see has 8 leds and 8 dipswitches on it.
·········· Just configure the respective pin for input or·output and way you go.
·········· Nothing to do .. input high led comes on as well ..
·········· Simple effective .. clean proto typing... no stuffing around conitinously with wires.
·········· The way these cards are made they also allow operation on 3.3V and 5VDC logic
···········and can also be used stand alone on solderless breadboard..
1 off···· PCB with the 10 Way idc header on it for custom proto-typing
·········· You can see the PCB it is really self explanatory..
4 off···· 10way ribbon cable to 10way sil in line connector
1 off···· Small SO 8 adapter board for Solderless breadboard apps.. or other
·········· A lot of nifty little chips these day's only come in SMD.
·········· Had some space on the panel so added this as well
The system is open to what ever you can think of really..
Personally into Factory Automation etc etc and analog + high speed pulses
are ideally suited for this Propeller... find a decent multic channel A/D chip and we will
make a card for it· and interface it.. we can work on this all together and make this a truly opensource
system· .. we have no problems wit this.. we can ship the PCB empty all std components..
We are hoping to get a preview on this in a local magazine here in OZ.. and get them going with
some real good Propeller related projects...
Added some extra as well (4/10/2007)
10 way ribbon cable adapters to 10 way sip so the cards can be used with Solderless breadboards
as well..
Cheers··· Ronald Nollet· Melbourne·· OZ
