@ Mike
I guess because all the blank Prototype Boards have gone, this has turned into "what other stuff is Parallax going to blow out". Ken started it with the Penguins.
My guess is they are not going to be free. Heck, all the mechanics are good, and it only takes two components to fix it! Maybe 4- to 50% off? No warranty, no returns. Or they will go on Parallax's ebay site and go to the highest bidder. Same disclaimer. No warranty, no returns.
Thanks Ken and Mike, i got my boards this weekend and will be put to good use! I'd like to score one of the penguins also, sounds like fun to tinker with!
Got mine today too..... hooraah! Thank you indeed Ken & Mike.
The Pengiun controller also sounds very exciting. Hopefully some might be able to flap their way across the atlantic!! That would be great to work on with my son. I could introduce him to robotics, and at the same time "justify" some further investment in parts for my own Propeller projects... a double whammy!!
Oh you area ll welcome.. K2 that is awesome I would love to see that project . I am hoping others will jump in and share what they build with these boards sort of are own "free blank proto board" project share post,,LOL
To be honest I am trying to think up something worthy of sharing with everyone I have so many MCU,s I do love the prop its the easiest chip I have ever seen and I mean that but there are a lot of prop projects I have been learning the BS2
and Holly got me into looking at the Tiny Atmel chips . but it would have to be something really cool . we already have the prop scope and lots of servo control boards and I could never compete with Rayman when it comes to displays
I am open for suggestions.. The one thought I had was I really need a freq meter in MHz-Ghz I might look into that but I want it to be affordable and not use exotic parts I think back a bit Chris or Ken did a Prop Spectrum Analyzer that would be very cool as well.
K2 what will use the fuel injection system on can we have details? I have an old Polaris snowmobile fuel injection system complete except the injectors its yours if you want it

Ghz not going to happen on the Prop. 20 Mhz is propably the tops given the spec on the PropScope.
The PropScope is sampling 10 bit analogue values at 25Mhz. With use of the counters I'm sure it's possible to do a freq counter to at least 80Mhz. With an external prescaler (A binary counter would do it) you could do fast multiples of that.

"Are you suggesting coconuts migrate?"
After getting my Proto Boards late, I just got around to look at was is going on with the traces on the board. I went ahead and made a couple of good scans that I will share. It is easy to open them up in Photoshop and zoom in othe the areas in question. I also enhanced them a bit to bring out the traces a little.
I don't know if anyone else has discovered what the two pads are between the servo header. I though they might be for some caps between the power rails, but they are used to cascade VCC VDD to the next group, since VCC VDD is feed to the outer most servo groups by default.
How these scans can be of some use. My eyes ain't what they used to be!

BradC, · Do you know of any prescalers that can accept a 1GHz input ? That goes down to low frequencies too ?
· A divide by 256 would probably work good. 1Ghz in, 3.9MHz out.
· I might be up to the challenge of a 1Ghz frequency counter.

Not off the top of my head, no. I thought it would be easy enough to look at some of the HCT 74 series binary counters and go from there. My idea was to take something like an 8 bit binary counter and squirt all 8 inputs directly into 8 prop pins, you could then pick your prescale value by the pin you chose to monitor.
I've just picked up some nice test gear, including a Tek SG503 250Khz-250Mhz leveled sine wave generator, so I intended to have a bit of a play with this idea over the next couple of weeks (time permitting).
<edit>
10 seconds of google-foo brought up a nice, versatile prescaling front end design good for in excess of 2.5Ghz. With some modification to the main prescaler to make it variable ratio it could be extremely versatile. More than just an 8 bit counter though.

I tried to edit my last post, but the forum software threw a wobbly.. so anyway :

On the slower and cheaper end, a 74VHC4040 will do 210Mhz.

Got my boards today - Way down here in OZ.
Just wanted to say - HUGE thanks to Ken and Mike.
I don't know of many companies that would go the extra mile for customers. You guys ROCK.
Again THANKS.

Corrected the VCC to VDD in my last post.
Good job Parallax for making a quality board for a great price!

I just noticed the url I had in there is not there! Not much good talking about a prescaler if you don't know what it is.
