The 8535 doesn't work with DT107, you should then us
the SIMM100 instead.

Hi Gang, due to Ben Wirz in the US changing direction with his future, I
purchased what was left of his SimmStick stock, and have some orphan
boards left.

These obsolete SimmStick boards are now available.

14 x dt108 Video, needs the suitable video chip, and crystals, 
see: http://www.dontronics.com/dt108.html
Note **** The video chip used is  no longer produced. I do have enough
left to supply with these boards.
see: http://www.dontronics.com/cat_hard_micro_ic.html#STV5730A

3 x dt103 40 pin atmel 
see: http://www.dontronics.com/dt103.html

1 x dt206 atmel 2051 programmer.
see: http://www.dontronics.com/dt206.html

Rod Egan, my dealer in Perth Australia, is also sending me a small
amount of dt103's to add to the list.

If you wish to order boards, use the shopping cart and select a dt202
board, as it is the same price, but mention in the text box provided
that you want one or more of the above boards, or you will end up with a
dt202. :-)

Best you send me a message first to make sure I still have stock.

Cheers Don...

It depends on the crystal parameters, if you really want to calculate it, 
but 22 to 33 pF always works for me.

Hi
I am looking at using the DT205 relay board to switch 240v a/c @ 10 amps.

I am looking at using a SPST type of relay.

Does anyone know a relay that can fit this board and can carry this amount
of current.

steve t

I think it may be rather dangerous switching 240 volts at such a high
current on a Simstick. Why not mount the relay externally,  then you have a
much greater choice of relays, and no problems with safety

Correction to my previous email. Sorry I misread your message, but my same
comments apply to the relay board. Use the relay board to switch a larger
relay mounted externally, which can handle the current and voltage

Yes I did have a number of reservations about the PCB's capacity to carry
such a current, even at low resistance.

I did notice in the writeup of the DT205 there was an option for switching a
relay of this type, but the relay was obsolete.

I think I will use a DIN rail, and mount relays using the correct relay
carrier.

The DT206 board does beg the question on how much current would be able to
be switched by the onboard relays, and at what voltage. Don, you might think
of a warning re this. Would the board carry say 240v at a low current of say
3 amps.

I am also looking at using some form of silicon based switching device eg a
triac. Has anyone got any suggestions?

My application is to switch household appliances on and off on a regular
basis.

I also notice that some electronic kit companies in Australia have for sale
boards with relays on them that are switchable by the printer port, and
specify current and voltage of this level. I have yet to examine these yet
to see if one is comfortable using them. No good, if the house is burned
down.

My suggestion is to forget the relay socket and just use an industrial
contactor (relay) that snaps on the DIN rail directly. The wires will go to
clamp type lugs on the unit. Contacts are rated 600 volts at 10 amps.
Normal voltages used in the US are 480 or 240 3 phase but 240 single phase
works well, will allow you to break both power lines and still have
contacts left for pilot lights, etc. Coil voltages are from about 12v dc to
480v ac. Pick the one that works for you. Many large companies produce
these products in a standard form factor. We call them IEC contactors. Buy
local if you can but watch the price because these things can be pricey if
you are not careful. Our plant has units turning on and off every 30 sec.
for 2 or 3 shifts - 5 to 6  days a week. We replaced one bank after more
that 3 years of service. All had arc damage but still worked.

Hello !

I don't know how many relays you are trying to control.  The relay
board is designed to control a number of relays when you don't
have enough microcontroller pins.

I use optoisolators such as 4n33, 4n37 to control relays.  A
clamping diode is needed across the output to protect the
opto. There are dual and quad optos, I just don't use them
because of the price, and if one goes bad, I have to replace
the whole unit.   There are also very tiny 5v relays. You can
probably fit them on the proto part of the board.

By the way, when a high voltage relay goes on or off, it
does produce a spark even if you cannot see it.  There
are two side effects.  One, it feeds a voltage spike back.
Second, it acts as a spark radio transmitter, which is
one reason I don't want it close to the micro.

Hope this helps too. Just my 3 cents.

fred

Hi,
From a safety point just use low voltage relays on the DT 206, and provide a
separate "control" voltage, ie. 24 vac and switch that to control Hi volt Hi
current relays.
The neatest and safest  solution would be to install a small "consumer
switchboard" and fit din rail mounted relays or solid state relays. there would
also be a 24 vac powersupply module that would fit as well!
This would require a licenced electrician to install. and would be permanent and
need dedicated power outlets.
Another way would be to build "relay boxes" that contained a 240 Vac relay with
a 24 vac coil, a short flex and 3 pin plug and a 3 pin socket (possibly a
"bypass" switch to over ride the simmstick control). This box would be placed
adjacent to the "appliance", and connected to the simmstick via a pair of low
voltage wires.
This you could build and install yourself, play safe and include fuses and
double pole switching to make the best job.
Cheers
Leon

Hi,

I am Mohan a Grad Student from Gannon University doing my Masters in 
Embedded Software Engineering.

I am currenlty planning to work on a Project which uses 
MSP430F147IPM. I have the chip, and the Adapter to burn, but I dont 
have the board to use. Can any one please let me know where and how 
I can get a board to mount the chip and burn the Program into the chip.

I dont want to take a Risk of wasting the chip trying to Solder it, because 
I am totally new to the concept of Soldering. This chip is a PQFP. 

Please help me.

Thank You,
Mohan.

Hello,

I haven't seen any simmsticks that accomodate the
MSP430 yet, but if you can use the 149 part, see:
http://www.olimex.com/dev/

someone in the UK is looking at this, but until it comes along, sure I
have heard good things about olimex, and have been aware of him for
years.

I exchanged fraud messages with him a few years back. :-)

I've made a couple of PCBs at home for the smaller F110/F112 chips, 
including one for the SSOP package. I could do one for the F147, but 
soldering the chip would be a bit tricky without soldermask.

Don,

I like the fraud page you have on your web site!
We need to nail these people who cheat. They hurt
us all when they do these crimes!

There should be some kind of "industry wide" place to
report these crimes.

I'm also waiting for an MSP430 SimmStick!

I also like Olimex. And their prices are unbelievably
low!

Do you have any plans to come up with a new SimmStick
video option?

Eric

I wondor if we could talk Olimex into producing some of these
SimmSticks with a 430 already soldered in? I'd order some
of these without thinking twice.

The 430 is picking up popularity fast. And the SimmStick form
factor is sweet!

I guess one day someone will get it all together.
It's a little like Spam. I am hoping that one day the law and technology
will stop it.

I think the real problem is the 1.26mm (.05") thickness board used.
I'll send this onto Tsvetan at olimex for comment.

and this thickness board is Internet friendly. What I mean by that, is
that it will post in an airmail letter and weights in a lot lighter than
the 1.6mm board. It also drills and routes easier. I don't know why it
isn't used a lot more today. 

And it is a must to fit the SimmStick 30 pin socket arrangement.

Mind you, one can always use the 30 pin male/female pins on standard
size boards if needed, I don't know if users would warm to this.
Comments?

To Tsvetan:
Hi Tsvetan,

are you able to produce 1.26mm (.05") thickness boards?
any other comments welcome,
could you please respond to me directlyt at:
mailto:don@d...
and I'll pass any info you have onto the list.

Cheers Don...

I've just created the part with the PCB package I used. I'd assumed that 
that the footprint had 0.65mm spacing pads, but they are 0.5mm. I could 
probably just about make the PCB at home by getting the film printed on a 
1200 DPI printer and using bubble etching. The best I can do with my own 
printer is 0.65mm spacing pads. I'll have a go just for the hell of it.

I've already asked Tsvetan about this, and he can't do it. I've had some 
good prices from a co. here in the UK for 1.26 mm prototype SimmStick PCBs.

I've already designed a SimmStick for the 110/112, but only one dealer was 
interested in stocking it, so I shelved the idea. I've also prototyped a 
normal thickness PCB for the chips that can be connected to the SimmStick 
bus adaptor.

yes, sorry Leon I do remember you saying that about Tsvetan.

OK, I'm not real familiar with the TI chip, but I know it is gaining
plemnty of momentum and good acceptance.

It really needs micros soldered to boards then?

Hi Tsvetan, and thanks, 
Leon Heller just reminded me that he had asked you about this in the
recent past.
Nice to hear from you again. hope all is well.

Yes, all the chips are in SM packages, some (the bigger ones in PQFP) with
0.5 mm spaced leads. 8-(

PCBs for all the chips are easy to design, as TI have arranged all the I/Os
very logically. It only took me a couple of hours to do a prototyping board
for the F14x (PQFP-64) routing it manually. That included creating the part
for the library. It's single-sided with a couple of links. I think it's
quite pretty, but I'm biased. I've still got to add the JTAG connector, and
I think I'll add an RS-232 I/F. If anyone's interested in seeing it I've put
the image on my web page:

http://www.geocities.com/leon_heller/f14x.html

I did it primarily to get a bit of practise at manual routing. I normally
use the (quite good) Bartels autorouter, but it makes a real mess of this
type of board.
