That depends on what you want to isolate - AC, DC, inductive, resistive load
voltage and current. I do AC resistive loads often - with an MOC3010 for
120V or 3050 series for higher voltages. A 220 or 330 ohm resistor works
well in series with a 5VDC input (pins 1 & 2). The triac output can be used
in either direction to gate a larger triac or SCR, from anode to gate with
another 180 or 220 ohm resistor in series with the gate. If the load side is
also DC, there are scores of transistor output opto's to choose from. Try
www.qtopto.com or www.fairchildsemi.com where there are lot's of ap notes
showing opto outputs driving many types of switching devices, from discrete
semi's to SSR's.

The PIC 16C55 (core micro of the BS1) has a per-pin current limit, as well as
an overall current limit. You must follow the per-pin limit until such time
you bump into the overall limit -- then you have to lower your per-pin
current if you need more active.
Please keep in mind that this is not a Stamp limitation -- this is a
limitation due to the construction of the PIC 16C55.

I suggest you define your project first.
How many alarm points will you monitor?
Are these normally open or normally closed ckts? Do you want to know only
that an event has occured at an alarm monitor point?
Do you want know which monitor point generated the alarm?
Do you want to know that the alarm detection points are operational before
going to an alarm state?
How are you going to display or sound an alarm condition?
Will there be any time limit when an audible alarm can sound?
Is there a requirement that this alarm circuit remain fully functional if
AC power to the building is lost?
This is not intended to be a complete list but one to get you started in the
definition of your project.
Good Luck

The stamp actually prefers the TTL levels you mentioned. Also a simple series
resistor (22K or so) and a diode clamp will let you interface REAL RS232
signals to the STAMP on any I/O pin or any other device that can't handle
RS232 like your transceiver. You may need to use an inverter (NOT gate) to
get the logic correct.
Suggest that you look at page 3 of the INEX-1000 schematic for an approved
interface to the stamp. The schematic is available at the Parallax web.

Thank you very much for the reference, I really like the book.
For those who might have trouble with the earlier reference, it dodn't work
when i tried it.
Goto the TI home page, and perform a search on "op amps for everyone", you
should get a search list link to the book, like this reference below.
Clicking on that link should fire up the Adobe Acrobat (PDF) reader plugin
for your browser.
With eighteen chapters covering everything from basic op amp design to
filtering techniques and circuit board layout, you'll find diagrams,
equations, examples, and reference material to aid the designs you're
developing now....
<<Download the complete book or just the chapters that interest you. You'll
also find information about how to purchase a hard copy edition.

It's really not tough -- a simple application of Ohm's Law. There are three
values you need to know to do the calculation
* Circuit voltage (if using a Stamp pin, this is 5 volts)
* LED forward voltage (usually around 1.4 volts -- but can vary)
* Current to run through the LED (most will light nicely between 5 mA and 10
mA)
This is a series circuit, so the current through the LED and the resistor
will be the same. The voltages across each will add up to the circuit
voltage (5 volts). Since the LED uses 1.4 volts, there will be 3.6 volts
across the resistor. Now we can reorganize Ohm's Law (E=IR) so that it looks
like this:
R = E/I
If we want 5 mA through the LED, R = 3.6 / 0.005 --> 720 ohms
Since you probably won't find a 720 ohm resistor, use the closest "typical"
value (680 ohms --> 5.3 mA) and make sure that you don't exceed any of the
Stamps limits on current.
Each Stamp pin has a limit on how much current it can source or sink, and
groups of pins (OutL or OutH) have total limits as well. Then, there's the
limit that the Stamp voltage regulator can supply. Low current LEDs are
becoming more and more popular, so it's getting easier to light a lot of LEDs
with just the Stamp.

The resistor in question is a potentiometer, and is used to supply a voltage
from 0V to the +Ref voltage for
Analog to Digital Conversion. Read the information above the circuit diagram
and the data sheets for the ADC
Chip. The arrow indicates the center arm of the potentiometer and is connected
to the input pin of the ADC Chip
pin # unknown, but can be found on the data sheets for this chip.

"The circuit simply reads the voltage at the chip's input (Provided by the
47k variable resistor), " right
"voltage at the chip's input (Provided by the 47k variable resistor)," now look
at the data sheet for the ADC
chip. The Data Sheet can be found by doing a google search for TLC548, look at
the first link it is in PDF
format. The input pin is pin 2. When looking for information read the whole
message not just the parts you think
are important, I did say look at the data sheet for the ADC chip. There is a
lot of "I think it is ... or It
might be this ... in this E-Mail", but no one has mentioned looking up the
information about the chip, a lot of
assuming here and you know what that means. Reread my message and you will see
that I did mention the data
sheet. I did not make an assumption about what the arrow in the schematic was,
I looked closer at the problem.
Have Fun !!

One thing I've dreamed about is a robotic maid... :-)
Perhaps starting with one that will, when it's "GO" button is pressed, go
around the house, create a map of the house and remember it for next time,
and then vacuum the place. Once finished, or if it needs to while part way
through, automatically go back to it's base and recharge it's self.

I don't know Java, so can't say anything about the Javelin..."
This situation could preclude the amount of help you could get early on. I
can't say how many
on this group do or don't know Java, but there are many who are REAL good
with Pbasic's more
complex programming and fixing the quirks.

first stamp to buy really depends on how many i/o pins you need, how much
room for program, how much room for data, and what kind of speed you will
need.
bs1 has 8 i/o real small program
bs2 has 16 i/o larger program faster
bs2i industrial temp range of above
bs2e has 16 i/o more ram and eeprom space
bs2sx faster version of above stamp
bsp24 20% faster than above and many more special instructions
bsp40 same as above except 32 i/o pins
norm
the web site www.parallax.com has all the info you need and its easy to
navigate.

If you can afford it, I HIGHLY recommend going with BS2p24 Professional
Starter Kit. I'm working with a BS2p24 right now and the extra flexibility
is really nice. The advantage of getting a starter kit is that it's great
to just do some of the experiments to become familiar with Pbasic and the
various interactions the stamp is capable of. I bet many of the experiments
in the kit would later apply to things you might do with a bot.

Hi uploadjoe. I am pretty much in the same boat as you. My first piece of
advice would be for you to go pick up a Nuts 'n' Volts magazine. There are some
good advertisements for electronics in there, as well as articles specific to
the stamp.
My first stamp was the BS2. I also have a board of education. Get this kit
because it comes with a manual that has lots of easy exercises for people like
us. Also, download and go through all of the Parallax free .pdf manuals.
Check out this book: Robot Building for Beginners (ISBN: 1893115445). It has a
really good overview of electronics for mechanical minded people (I'm a
mechanical engineer by schooling). It also lists suppliers of electronic

I did purchase the Javelin stamp too. My decision here was that I am not a very
good pBasic guy (I've only been doing this for about 6 months now) and I already
know C/C++. The Javelin is very powerful, so it should be able to do pretty
much anything you need it to.
Hope this helps.

Hi uploadjoe. I am pretty much in the same boat as you. My first piece of
advice would be for you to go pick up a Nuts 'n' Volts magazine. There are
some good advertisements for electronics in there, as well as articles
specific to the stamp.
My first stamp was the BS2. I also have a board of education. Get this kit
because it comes with a manual that has lots of easy exercises for people
like us. Also, download and go through all of the Parallax free .pdf
manuals.
Check out this book: Robot Building for Beginners (ISBN: 1893115445). It
has a really good overview of electronics for mechanical minded people (I'm
a mechanical engineer by schooling). It also lists suppliers of electronic
components.
I did purchase the Javelin stamp too. My decision here was that I am not a
very good pBasic guy (I've only been doing this for about 6 months now) and
I already know C/C++. The Javelin is very powerful, so it should be able to

Everybody thanks for your help! I think I am going to go with the
BS2p24 since I don't know java... and I am sure I will needs lots
of advice... maybe in the future I will upgrade since the hardware
appears to be interchangeable. I will probably get the stamp and
a couple of sensors and start messing around with them in the
next few months.
Nathan, thanks I will check out Nuts and Volts and I will look for
that book.
Thanks again.. I am sure I will chime in now and then with so newbie

voltage and current. I do AC resistive loads often - with an MOC3010 for
120V or 3050 series for higher voltages. A 220 or 330 ohm resistor works
well in series with a 5VDC input (pins 1 & 2). The triac output can be used
in either direction to gate a larger triac or SCR, from anode to gate with
another 180 or 220 ohm resistor in series with the gate. If the load side is
also DC, there are scores of transistor output opto's to choose from. Try
www.qtopto.com or www.fairchildsemi.com where there are lot's of ap notes
showing opto outputs driving many types of switching devices, from discrete
semi's to SSR's.

How about an LM386 chip? I've used that with good results. Easy as falling
off a log. Use the filter circuit shown in the FREQOUT manual pages.
Instead of an ASCII schematic, try:
http://www.warplink.com/user/kencan/lm386.htm
or a few less parts:
http://www.chipcenter.com/circuitcellar/askus/may00/Q4_00_15a.pdf
Read the datasheet: http://www.national.com/ds/LM/LM386.pdf
You can set the base gain, etc.

an overall current limit. You must follow the per-pin limit until such time
you bump into the overall limit -- then you have to lower your per-pin
current if you need more active.
Please keep in mind that this is not a Stamp limitation -- this is a
limitation due to the construction of the PIC 16C55.

How many alarm points will you monitor?
Are these normally open or normally closed ckts? Do you want to know only
that an event has occured at an alarm monitor point?
Do you want know which monitor point generated the alarm?
Do you want to know that the alarm detection points are operational before
going to an alarm state?
How are you going to display or sound an alarm condition?
Will there be any time limit when an audible alarm can sound?
Is there a requirement that this alarm circuit remain fully functional if
AC power to the building is lost?
This is not intended to be a complete list but one to get you started in the
definition of your project.
Good Luck

values you need to know to do the calculation
* Circuit voltage (if using a Stamp pin, this is 5 volts)
* LED forward voltage (usually around 1.4 volts -- but can vary)
* Current to run through the LED (most will light nicely between 5 mA and 10
mA)
A typical (sourcing) circuit works like this:
[noparse][[/noparse]Stamp]---[noparse][[/noparse]LED]---[noparse][[/noparse]Resistor]---[noparse][[/noparse]Ground]
This is a series circuit, so the current through the LED and the resistor
will be the same. The voltages across each will add up to the circuit
voltage (5 volts). Since the LED uses 1.4 volts, there will be 3.6 volts
across the resistor. Now we can reorganize Ohm's Law (E=IR) so that it looks
like this:
R = E/I
If we want 5 mA through the LED, R = 3.6 / 0.005 --> 720 ohms
Since you probably won't find a 720 ohm resistor, use the closest "typical"
value (680 ohms --> 5.3 mA) and make sure that you don't exceed any of the
Stamps limits on current.
Each Stamp pin has a limit on how much current it can source or sink, and
groups of pins (OutL or OutH) have total limits as well. Then, there's the
limit that the Stamp voltage regulator can supply. Low current LEDs are
becoming more and more popular, so it's getting easier to light a lot of LEDs
with just the Stamp.

Is it possible you are not clearing the LCD between messages.
So if you display:
123456
And then try to move the cursor to home and print Hi, you'll get
Hi3456
Maybe?

The resistor in question is a potentiometer, and is used to supply a voltage
from 0V to the +Ref voltage for
Analog to Digital Conversion. Read the information above the circuit diagram
and the data sheets for the ADC
Chip. The arrow indicates the center arm of the potentiometer and is connected
to the input pin of the ADC Chip
pin # unknown, but can be found on the data sheets for this chip.

"The circuit simply reads the voltage at the chip's input (Provided by the
47k variable resistor), " right
"voltage at the chip's input (Provided by the 47k variable resistor)," now look
at the data sheet for the ADC
chip. The Data Sheet can be found by doing a google search for TLC548, look at
the first link it is in PDF
format. The input pin is pin 2. When looking for information read the whole
message not just the parts you think
are important, I did say look at the data sheet for the ADC chip. There is a
lot of "I think it is ... or It
might be this ... in this E-Mail", but no one has mentioned looking up the
information about the chip, a lot of
assuming here and you know what that means. Reread my message and you will see
that I did mention the data
sheet. I did not make an assumption about what the arrow in the schematic was,
I looked closer at the problem.
Have Fun !!

Perhaps starting with one that will, when it's "GO" button is pressed, go
around the house, create a map of the house and remember it for next time,
and then vacuum the place. Once finished, or if it needs to while part way
through, automatically go back to it's base and recharge it's self.
Cheers,
Ben, Wellington, New Zealand.

This situation could preclude the amount of help you could get early on. I
can't say how many
on this group do or don't know Java, but there are many who are REAL good
with Pbasic's more
complex programming and fixing the quirks.

need.
bs1 has 8 i/o real small program
bs2 has 16 i/o larger program faster
bs2i industrial temp range of above
bs2e has 16 i/o more ram and eeprom space
bs2sx faster version of above stamp
bsp24 20% faster than above and many more special instructions
bsp40 same as above except 32 i/o pins

Starter Kit. I'm working with a BS2p24 right now and the extra flexibility
is really nice. The advantage of getting a starter kit is that it's great
to just do some of the experiments to become familiar with Pbasic and the
various interactions the stamp is capable of. I bet many of the experiments
in the kit would later apply to things you might do with a bot.

advice would be for you to go pick up a Nuts 'n' Volts magazine. There are some
good advertisements for electronics in there, as well as articles specific to
the stamp.
My first stamp was the BS2. I also have a board of education. Get this kit
because it comes with a manual that has lots of easy exercises for people like
us. Also, download and go through all of the Parallax free .pdf manuals.
Check out this book: Robot Building for Beginners (ISBN: 1893115445). It has a
really good overview of electronics for mechanical minded people (I'm a
mechanical engineer by schooling). It also lists suppliers of electronic
components.
I did purchase the Javelin stamp too. My decision here was that I am not a very
good pBasic guy (I've only been doing this for about 6 months now) and I already
know C/C++. The Javelin is very powerful, so it should be able to do pretty
much anything you need it to.
Hope this helps.

BS2p24 since I don't know java... and I am sure I will needs lots
of advice... maybe in the future I will upgrade since the hardware
appears to be interchangeable. I will probably get the stamp and
a couple of sensors and start messing around with them in the
next few months.
Nathan, thanks I will check out Nuts and Volts and I will look for
that book.
Thanks again.. I am sure I will chime in now and then with so newbie
questions as I try to grasp all of this.
Thanks,
Jeremy
