The "T" version is dead.
Here is a design (still needs some cleaning) after Mike's idea, between the sticks.
Unilaterally, all SR1206, IC's on the bottom (Dil).
Advice (good) I gladly accept.

Hans


I added new PDF!

During this time I have just the wiring diagram for the Dil-IC and ​​made ​​the footprint assignment.
Here's my outline 1:1

xxx I've printed PDF - not 1:1! xxx

Width: 83.8 mm - Height: 45.7 mm

Mike,
I was wrong!
I know what you mean now. That's a good idea.

My unusable board looked like this.
Between the sticks

PS. I use this http://www.ebay.de/itm/300766833706?ssP ... 1439.l2649

Oliver, right, that minimize the bridges is always with me in the end. (difficult) I'll try 0 ohm resistors, but that's always on one track. The bridges could also be installed at the bottom, for example with Enamelled copper wire. The one with the switch, as I ride around and over again, it will be...

A possible "T version" in SR1206.
As I said,
Problem is an appropriate switch.
Another variant would be to put a shorter board up on the "T-Board".
Tighten with the M4 screw.

I bought all SMD:

even small quantities.

It's not entirely true, until next March.
Fun enough,
Does anyone have any idea where we can get the switch?
The unsolder could be difficult.

Oliver,
thought well,
But I have to one-sided circuit board between the pads through!
The circuit path width is 14 mil minimum at the moment.
Underneath it will be difficult with the home production.
SR1206 o.k.? ha,ha--0603--easy-- I'm 64.

I think about a SMD layout. The existing switch board complete replacement? SR1206 (although all the parts I have in stock in 0805) With external MicroSD card. In the battery compartment, it is well placed. Pads in the 100 mil spacing! If needed larger (one sided!) We should first look for a source ...

Oliver,
here the last schematic.

The lid should be closed. -for the first-

Yes, this diagram. Oliver, it's all Ceramic Capacitors 10μF/16V - SR0805 100uF / 6 V SR1206 and 47uF / 6 V SR 1206 Everything shown in the photo. Without RF module I can not hear any noises. With the RF module a faint buzz, but only with the ear to the speaker. The voltage stabilization I have also ...

Oliver, you have converted the Gerber file, great! I have found a mistake in the diagram. Pin 13 (middle left side) must go to pin 28 of the M64! (no pin 29) The gain change I've taken back. R 10 now 33k. Connection "beeper" I have applied to the base of the transistor. I removed the beepe...

mbanzi wrote:I copied the schematic created a few pages ago into Eagle, but it probably needs to be validated. For example I couldn't figure out if any of the caps in the schematic are polarized, which I'm sure they are.

All capacitors are ceramic in my circuit, and therefore not polarized

i checked the smd files. What size are the needed smd parts? i am sure i can solder it but i have to work a little on pcb manufacturing and components sourcing... Thanks for your work... Joao what about the strip board plans? All resistors and capacitors are SR 0805. Exception C9, C10, C16 SR1206 V...

Joao,
Beeper's Pin!

correct, I have the schematic renewed in the post before.
Positive terminal of the electrolytic capacitor connected to pin 1

Oliver,
here, the most recent of my module.
I changed the gain with 10uF / 1k2 to 50. Pin 1 to pin 8
Pin 2 LM386 is now above 330 ohms to GND
Beep quieter, louder audio.
Hans

And now, can you give us last version of your board and scheme? :roll: And if it available, in some grafic format, because other beginners (and me too :roll: ) can't repeat your work only with foto. Oliver, I think there is a little problem, the connector - Card / ICSP - I could provide the board w...

yes, and the zip Hex-file.

Joao,
the one that Mike has just posted.
I downloaded the eXtreme Burner chose the Mega168,
and have set the fuses. The information I have ignored (no 328)
Simple and easy program. Even I get it!

Joao,
i take your Fuses!
Taa Taa.. it works!
Hans

Oliver, I have installed the eXtreme Burner.
What settings do you have?
It shows no 328

The Crystals come tomorrow in the mail from Reichelt.
I have only scrap.
This is it! I have to work tomorrow morning. In my old company.
To earn something for my hobby. Pensioners have a hard time.
Maybe it will work for you immediately. I hope

For all files. In between there is absolute silence.

I think it's the Crystal!
It has, as seems only 2,000 Mhz
What looks like a 1 belongs probably to name characters.
I will measure.

Joao,
when the announcement begins, you will hear a tone of 3-4 kHz.
In the background, the text is totally distorted sound.
Text is too much to say, it crackles softly

Looks certainly not bad! Backlight o.k. In corresponding to the switches but it's starting to whistle at. As long as the message passes. I use the 8-bit sound data. The beeper I have not yet connected. I will do that immediately. It must run with the old files? Or I'll have to install new? The Beepe...

Mike,
J1 to either programmer or SD card
Do not scare me that I'm wrong.
Where we are in grade,
I can program the 328 as 168 with Pony Prog?
Can it be that it's been going with epee?
The 328's in it.

So friends of the night,
it will be long!
The board is DONE.
Thanks Mike - with Crystal -
As big as the Emartee module.
Now I have to spread a lot of little chicken feed.
We will see ...

Hans

We did it! - I hope

Everything on it, on one side, but unfortunately 2 bridges.
Tomorrow is made the board. 42.5 x 34.5 mm.
First one (or two) bottles of beer for steady hands.
