SO PLEASE USE THE SAFE LINKS
sweet! now most pictures r up,
Thank you friendly MOD ;)

INTRODUCTION

* i am attempting this using my old Eurgle 9x that has a lite problem custom firmware issue, like i mentioned in a earlier post (throttle & display issues).

This is a HOWTO modify the 9x (V1) for SmartieParts board installation. it is in 6 separate parts so U can reply, give ur impressions, share ur experiences & advices in every parts. I will also be adding informations & details.

i had this idea of how to install the Smartieparts board in a case like me if U have a Version 1, 9x.

Woot U need:
- i used a very small of metal (scratch on JST connectors)
- a small piece of electric tape
- a very little piece of solder wire
- a drop of Medium thickness CA glue

Tools needed:
- X-acto knife
- cutting plier
- soldering iron
- a small flat file
- a third hand tool with magnifying glass
- a Dremel tool (facultatif)


U know the drill, remove the 6 screws,unplug...

Here is the part U need, circled in red.
Image
A small piece of unused metal from a JST plug. Very conductive & very thin.

The difference between is only a "DOT" away.
On Version 1 its here..
Image
Silver DOT on V1.
On V2 its here...
Image
Refering to "DOT" to determine the junction point in the yellow circle or equal or equal DOT on V1.

In a logical order here are the steps.

STEP #1

With a fair amount of light and using the third hand tool with magnifying glass,
remove the "green paint" over this spot,here in a yellow line on the picture.
Scratch it with an X-acto knife.The magnifying glass from the third hand tool
will be very useful dealing with small to avoid mistakes & unwanted scratches.
Try to avoid scratching too close to the DOT already made by manufacturer,
do not disturb neighboring connections in order
to prevent unwanted current bridges & short circuits.
Image
This is a precision job, so take your time.
*i personnaly chose a 60* angled blade to avoid deep scratches on the copper.

Use Isopropanol 99% or Alchool 70% &+ to clean the residue of green paint U just scratched,
which i did after every X-acto scratch giving me clear view on what i was doing.

STEP #2



Image
*maybe tape on the other side also to avoid the upcoming solder wire to be loose.
I found out while doing it that it is a good thing to tape all around the copper expose &
all over the manufacturer DOT. This will be useful in a moment.

So look at the picture and imagine black tape all around the copper piece and do the same.
Stay on the green, the mainboard , don't tape over the components.

After cleaning, put a piece of electric tape on this location. Where the manufacturer DOT is I made a
spot with a red marker to give me an idea of the size & shape of the modeled JST plug metal piece.

TiPs: I use precision tweezeers to move the small pieces of tape around.
To move to small pieces of tape around & under the third hand tool magnifying glass use toothpicks,
it makes way easier & precise i use 2 at a time when needed.

STEP #3

Now you use to JST plug metal piece to make your new DOT.
So look at the logics and make a simular shape & proportional sized DOT,
when shaping your metal piece. it s OK to make a bit oversized DOT like i did
but avoid making it having contact with mainboard, to avoid short-circut.

*Now i a good time for Dremels & small files to get the right shape.
Image
Compare size & shape of the metal plate by putting on the tape, look exactly at the spot it should.
When U got the right spot, good shape & size then........

STEP #4

Now that you are sure of the correct place to put your DOT.
take a small piece of solder wire (as small has U can) like 0.5mm or
like i did is to take 1mm solder wire and filed it to the size required,
and for the length i eye check beside the copper surrounded by tape now.
Using the X-acto knife cut delicately & after comparing with with the size
needed to fit perfect inside and not over the tape.
*It's a precision job so take your time.
Put a small drop of CA medium where the is a small blue spot indicated on the picture,
U put the CA on the spot between the layers of tape & the new metal piece U just made.

(same picture has in Step #3)

The yellow on the picture now represents a fine solder wire piece.
* i avoided CA activators (kickers) because its wet and i don't know at what speed it evaporates.

When the CA is dry(5min-10min), on the yellow part where now the solder wire is,
the solder wire being sandwiched between the copper on the board & your new DOT,
take your soldering iron & apply lite pressure over the small area where the solder wire is trapped
to make a good solder and provide conductivity to your new DOT:)

CONCLUSION

You now have a new DOT where the contact of the SmartieParts board is made
like on the V2.

So now U r making contact with your SmartieParts board. Because U made made
a new DOT & the contact point on the board has a spring,
http://magicmojo.webs.com/apps/photos/p ... =149681045
it gives us a little more
thickness possible to work with.

Where the blue line represents the solder made.
It's done!
Whit no fragile wire between main board & SmartieParts board.
Image
Easier soldering then usual method. Well for me it is, after what i did whit
my virgin Eurgle on the first attemp.

http://magicmojo.webs.com/apps/photos/p ... =149915412
The tape now has melted a little and isolates the metal plates.
Avoid any contact of the metal plate with board components.

Now put back on the SmartieParts board & plug the EL.
Oups! Plug the EL backlight onto the board before putting
back in place the Smartieparts board, it's easier.


Thank You.
