Don,

I pressed the "Order" button on the DT007 page. If I was able to order
something that you hadn't finished making I don't know if I'd be
impressed... or frightened... ;-)

The 2.1 mm power adapter is just like the one on the DT003, right? I'd like
to see that the footprint is the same too, so that I can replace this
connector with a 2 position screw terminal with .2" spacing. (Like I do on
the DT003)

Great design!

-Rob

OK, thanks for the feedback.

I will take a look on DT003 and insert it.

Thanks. I have had several asking for such a board, since many
of the boards (DT103/DT104/SIMM100/SIMM101) has on board power
supply and RS232 tranceiver which lead these signals to A1/A2,
but there is no mother board today that support this feature,
so I want a small cheap mother board to be able to add one
microcontroller module and a proto board or a peripheral, which
is enough in many cases.

Hi!

Has anyone on this list found a reasonable plastic box for SimmSticks? I
have a person that I'm trying to help fit just a 2" SimmStick into an
enclosure.

For that matter, has anyone discovered a nice box that could house a DT003
with some cards in it? I'm just looking for some suggestions.

Great idea Lars. This board could be valid in a lot of designs.

What is the "STK200/Kanda programming interface"?

What are the coming BASIC Stamp Simmsticks? Is this a Parallax product or
is someone else putting a Stamp on a Simmstick?

Thanks

see:
http://www.dontronics.com/stk200.html
This is a product made by Kanda, and distributd by them and Atmel
distributors for the most popular variant of AVR micros. The header is
becoming a bit of a defacto standard for AVR programming and Dontronics
and Lawicel are introducing it to new designs. 

The only problem with it is that it is a chunky socket and doesn't lend
readily to SMD design. In fact it is very large on standard DIP designs,
see:
http://www.dontronics.com/dt006.html

StampStick is a product from Ben Wirz (wirz.com) that is very much along
the lines of:
http://www.dontronics.com/simm101.html that is, using a 1" SimmStick
form factor and SMD, but with a Basic Stamp One chipset. Yes, a real
Parallax chip. I think Ben will be moving into BSII's also.

I have done a CC of this to Ben, and as he hasn't announced this product
yet, I'll leave that to ben, but it is real and i think i have units
being shipped to me now, so details will follow shortly.

Just a thought Lars & Ben.
Ben may like a 3 pin header on the dt007 board for the BSI programming
cable!
BSII is done via rs-232, so Ben should make sure this is also workable
on the DT007 board.

Cheers Don...

Hi,

I was just about to answer Bruce, but Don is fast ;-)

All who buys an STK200 has the programmer, so why make
a new interface when a well proven one excist. It is
an ISP connector for In system proramming similar to
a JTAG connector.

Yes, right. Good idé. I contact Ben about this.

Hi Bruce,

I'm the one doing the Basic Stamp SimmSticks.  I have the BSI version done,
you can downlod the PDF for it at:

http://wirz.com/SS1/docs/StampStick1.pdf

Retail:  $37  USD
Reseller:  $22.50 USD

	The Basic Stamp IISX version is currently being manufactured and should be
available in a few weeks.  While they use Basic Interpter chips purchased
from Parallax they were designed and manufactured by me.  Parallax was
extremely supportive in helping me do the design so I feel they are behind
the product also.

Hi Guys,

	Yes it would be good to make the new  board compatable with the Stamp
Stick 2SX .  I actually need 3 pins from the DB-9 brought into A1, A2, &
A3.  You may want to make a jumper for A3 which is used by the BSII for
reseting the chip and is not a SS psuedo standard pinout.  I'm on the road
now but I'll send you a hookup schematic as soon as I get back.  We don't
need anything for the BSI because it has a 1x3 header on the board that
fits the standard parallax programming cale.

	I actually have a motherboard that I have been working on also but it is
more of a bread board/protoyping board.  The main reason I was doing it was
that I didn't have a way to program the Stamp Stick 2SX without hacking up
a DT.003.

Andy,
The PSU is 12VAC, 500mA. I have a 1000uF as the smoothing capacitor 
after the bridge. 12VAC should be OK wrt the DC voltage produced (ie 
about 17V) but I suspect the problem is the load regulation more than 
likely due to the 1000uF not being large enough.

Regards
Robert

Hi,

Just a small note regading rectifying.

I use as a rule of thumb, 6000uF per 1A load. I have tested
this with an oscilloscope to see when the DC starts dropping
periodically.

And for those who doesn't know (I guess many does), the
voltage from a AC to DC over a rectifier gets SQRT(2) times
bigger (that is 1.414 times bigger) at 50Hz. Havn't tested
on 60Hz if it is the same (would be good to know).
So 12VAC -> 16,968VDC = 17VDC (if you have proper Capacitor).

Hi!

Has anyone on this list found a reasonable plastic box for SimmSticks? I

For that matter, has anyone discovered a nice box that could house a DT003

Robert,

My programmer, the ASAPROG, uses the same input configuration (470uF
cap) as the DT001. No prob's with regulation. The VPP line is not a
heavy current user. I'll test out the performance using your software on
my DT001, which works OK with Nigels software. 

What 74 series device is fitted? and how have you setup the picprog
software? I'll re-create it and let you know.

Rgds...

A bit of scoop!

The peak of a sine wave is related to its RMS value by 1.414 and this is
independent of frequency.

Hi,

How much currrent does dt001 draws with the basic components and the 
programmer components.

I bought a 14VAC 200ma wall transformer fo $2 yesterday :-) let's see 
whether it will work or not.

Wirz Electronics is proud to announce our first contribution to the
SimmStick family of boards.   Stamp Stick One is a Parallax, Inc. Basic
Stamp One Compatible SimmStick Processor Board.  It features a large
prototyping area, a high current onboard regulator, and of course a
SimmStick form factor.  Please feel free to vist our web page for more
information and the product datasheet.

SLI-OEM - The most cost effective Serial LCD available!

I am willing to extend PCB manufacturing help if required in bulk (minimum
100 lots) for the simstick hobby club members. Cost likely to be the lowest
in the world for sure and FR4 grade double sided or up to 14 layers with
solder mask possible. It is not a commercial offer and is non-profit offer
to promote the cause. Requirement is CAD output or positive and negative
films and manufacturing cost plus mailing charges only. Service is free from
the Robotics Club of India.

We are very close to finishing the dt107 40 pin (8515) and 28 pin avr
SimmStick board.
Final feedback now appreciated.

Do you manufacture PCBs in Gwalior or get it made from outside?

Hi Don,

Would that support the programming of AT89C51?

Will support the chip, but not the programming. This is a target board,
not a programmer.

Thanks Andy,

The 74 device is a SN7407N. The setup for the PICProg software is as 
follows:
Software picprog16 V1.21
Vdd - D2 selected, Invert selected, OFF
Vpp - D3 selected, Invert selected, OFF
Output - D0 selected, Low
Clock - D1 selected, Low
Input - ACK selected, Low
Port is 378H
Delay time 20mS

These settings are the default settings for the DT001. I am not sure 
what each does!

Thanks for the help.

Regards
Robert

Yes,  I would for something like a 2716 (I presume Single +5V rail) but
doesn't really matter

There are several articles have been written in various Electronics Mags,

They generally use a counter for the address lines..

> possible? could i make a stick that would work w/ the DT001?

Since you only need a lab-type hash up,  should be easy enough to
breadboard.  The hardest thing is probably getting the programming
specs for the EPROM's you have  (there were variants).

Best of luck,  (I have an old EPROM programmer on an HP64000
but I think that time has got to it).
