im ready to send the PCB for fabing.
just needs to expand the pads for D1

also, we are missing 1uF and 2.2uF 0805 smd reels
if anyone can buy these that will help, here are two from same store.

We have to use blue LEDs with higher forward voltage. I'll try to find
some. Guy/Udi pls help.
We were talking about other changes:

1. Change R2 to 1.5 Kohm, Add Solder Jumper to get rid of the red LED.
(option to save power)
2. Replace the USB connector.
3. Move some parts to the other side of the board (MPU, LDO)
4. Add option for MOSFET on the other side of the board

regarding blue leds, maybe one of these -

http://www.aliexpress.com/item/Free-shipping-1000-pieces-lot-SMD-0805-Blue-Super-Bright-SMD-LED-Lamps/1085721916.html

http://www.aliexpress.com/item/0805-side-blue-light-SMD-LED-light-emitting-diode-chip-lamp-beads-side-emitting-ultra-brightness/741640218.html

they don't give a proper datasheet though, only voltage drop at the nominal
current (usually 20mA), and I think we use less current than that, so still
inconclusive...

I'm not in favor of moving parts to the other side because it greatly
complicates the option of oven-soldering.

The blue LEDs serial resistors are 68 Ohm, for 5V Vcc the current will be
~24mA.
The 1st LED is rated to 20mA max.
The 2nd to 20/30 mA (Typ/Max)
What do you think, shall we take the chance? or we need LED with higher max
current?
Pay attention, the LED size is 0805. I think that the footprint for the LED
is smaller.

I think we can take the chance, and/or increase the 68 Ohm resistors

+1 for Ver16b.
I prefer balanced 2 legs than Vcc.
Near each hole there is a *"2.0"* marking which should be removed from the
silkscreen.
The blue LEDs that Guy found are 0805. I think that our current footprint
is smaller.

The coin cell is a bit risky!
If the coin cell is inserted and you plug the USB connector or connect
Vbatt the coin cell might explode.
At the beginning when the coin cell was included in the design we add
a Schottky diode
to protect the battery.
The problem with this solution is that you loss 0.2 Volts on the diode
which lives you with 2.8 Volts only for the ATtiny.
The minimum voltage for the ATtiny85 is 2.7 Volts.
In that case you need to use the ATtiny85/V. The minimum voltage for the
ATtiny85/V is 1.7 Volts but it cost much more.

For all those good reasons we decided to remove the coin cell.

Alon, sorry, I didn't noticed I send it just to you. It is corrected now.

To: Alon Levy <***@pobox.com>

The same problem remains.
You must include the protecting diode because someone might connect
external voltage while the battery is inserted.
If you include the protecting diode the cheap ATtiny85 will not work and
you need to use the costly ATtiny85/V.

We should include the diode in the design but not populate it. If someone
need the coin cell he must populate the diode and replace the ATtiny to
ATtiny85/V.
That way we keep the low price for the mass production.

Yair, can we meet today or tomorrow in order to finalize the design?
Can you send the last version (eagle files) of the design?

I added a schottky diode D5 to the design. It's not easy to find a place to
put it on the board.
It seems possible to do the following:
1. Rotate the coin cell by 180Â°.
2. Move some components and locate the new diode near R4.
Can you try it?
I was trying but couldn't find the B1 on the brd.

i've placed it on the bottom
as its almost a shield i think its fair.

but, it will mean the battery will have to be raised by a few mm - as its
mounted on the same side (bottom). it will not be able to sit flush on the
bottom

will not be around next week
possibly Sunday morning

I thought it's a battery holder so it is isolated all around.
By this time I already manged to locate it and I'm playing with the
placement. I'll send a new version later.
Sunday morning seems right.

maybe the coin cell shield can be a little longer so we can solder any

would be able to connect it while the shield is plugged to the board.
I assume we won't be planning on using USB on coin cell power alone.

Attached here is the design of the board including the coin cell.
I moved the coin cell B1 to the other side of the board.
I moved some components to make room for the schottkey diode D5.

- The standard (cheap) version of AT-Tami will come without B1 and D5
and with ATtiny85.
- For projects which need coin cell we will assemble AT-Tami with B1, D5
and ATtiny85/V.

Yair, can you verify that I didn't made any mistakes in the PCB layout.

The idea is awesome but they want too much money for it
A simple 3d printer can do 10-20 covers an hour...

zvi came and we dicussed this design.

aesthetically , i love it.

8pino use the tinker bootloader, we use the micronclus. adafruit industries
choose to implment a new design, i dont know by how much or did they have
branched of littlewire as MC did.

cons:
* no protection for the usb from stray currents (we use schotkky diodes) .
i see that in other low cost attiny85 designs.
*usage of the 20Mhz attiny in the QFN packge -
while the board is tiny (a quarter of ATtami size) that packge limits
assembly options

and. you can't run it on coincell at low Hz.

[1] (ot a hard build as is. it took 40min for yuval and i, doing hand

How does a reflow oven works with components on both sides?
Do you heat only from above, and the parts below never get warm enough to
fall off, or is it because the board is lying on a flat surface, holding
the molten components on the lower side still in place?

there were some "unknown" leds in the ATtiny box. they're red leds. FYI.

experimented with some 0805 0603 soldering. got to say.. great success, it
wasn't as difficult as i imaged.
i left the result on the electronics table.

The Reflow Controller hardware is ready to use.
There is also a sketch I wrote which performs a limited control.
it can go, full throttle, to the soaking temperature stay there for the
required period, then go to the top temperature and stop.
I don't have control of the heating or cooling slopes.
I think we can use it as is with some manual help.
The only problem is i'm in Netanya. Not yet fully recovered. I will not be
able to come today or tomorrow.
If anyone is able to come to me I'll be glad to deliver the Reflow
Controller.

i just checked the board that came back, there was a stupid error
floating/missing connection between the enable pin and VBAT on the voltage
regulator (option A)
we need to jumper it but it will be delicate and ugly.

we might be able to connect it to VCC (option B)
or do the orginal thing, with option A

revision, i will send to fab tomorrow and pry it will get here
3-4 days FAB
3-4 UPS

let me know if its ok. double check :(

that horrible microusb, its also a mess to hand solder
i add some length to its pads. so pushed the resistor row back.
**note to assemblers: start with the hardest part, then go easy.**

i changed the board a bit, also add labels on pins to bottom
as the coin cell cant go to bottom when you have headers on, no space, it
goes on top nicely.
reset button access is possible %75

all is in the telavivmakers github, i (finally) got the right nudge to use
the github windows gui, its sweet.

nice last minute save.
Also +100 for proper github flow, it's really easy
Only a matter of time before github show nice diffs between revisions for SVGs as well (they already to 3D object diffs)

If anyone wants tips on how to work with git/hub (including large team workflows) i'm always available to explain.

and find (yet) another! diffrent! airwire*

PB5 (reset pin) is unconnected to the left bottom pad
means you have to add the jumper before using the floating programmer

arrrg.... next one is real.

@Yair, it appears kuddos are in order but I really can't understand most of
what you said, so I don't know what for :)
who's O (unless he requested anonymity that is)? where did the $ came from,
selling the ATTami's?
and what's the connection to the new space in the glass room?

I'm the notorious O, also known as Or Cohen on the book of faces
I did 3 TinyTami boards today, and enjoyed the process very much! :)

A few requests/notes:
1) I can't remember (and don't find on the wiki) the board definitions for
the Arduino dev. env.
2) For creating a jig for applying paste, you can use my 3D printing
services free of charge, given it doesn't take much of my time/paying
customers
3) It might be useful to have an Arduino for flashing, fuses & testing. Can
make the process quicker

And thanks for all of you who've done such a great work!

Hi Or,
It made me happy to read about your success with the ATTami.
If you installed the boot-loader ask Yair for instructions.
If you like to program the ATTami using ISP look here "
http://highlowtech.org/?p=1695" for instructions.
If you need further assistance please write.

These are the pins I would like to have on some TinyTami projects (yair,
what I told you about)
I didn't fit them all the way, because they'll stick pretty hard. Also,
using to little pins isn't so good because they don't hold like the square
pins
But they're compact way more

Some tiny pr0n

And btw...
- Can I put the board again in the oven?
- Why won't we replace the reset switch to an NC switch, connected between
the LDO and the attiny VCC? That way, pressing it will momentarily
disconnect power to the mcu.
- Can I use the switch on pin 5 for digital input? I'd like to make a
little flashlight, and use the existing switch to control it.

Last week I had spoken with Tzvika about using the Reset leg as an IO.

Just a few days before I had seen this instructable that had made it.
I was not sure about the part but now I see that it was Attiny85.

I've suggested before to use an NC switch between the regulator and vcc pin
on the mcu to reset.
Can it work?

we need to test this assumption.

i think the fail here is that if you disable the fuse RESET pin (and by
doing that enable the PB5 pin as a "(weak) I/O pin") it will not allow for
flashing new code (as in trigger the bootloader-accepting-new-HEX stage)
EVEN ON POWER UP.

we can offer users to "free" that pin by offering a shield with following
circuity - -
