Thanx for that
....looks like it's the one I'll get then
ADDENDUM: Rather than start a new thread on the subject, I thought I'd add to this one.
Woohooo....yet another jiffy bag from HK
Following your advice
Hi/zuum,
I had bought this rumble pack from Ebay. It only comes to £8.50 inc. delivery
Before buying one I had a few concerns:
1) The official one bundled with games is always black in colour.....as mentioned I wanted to retain the same colour as my DS if possible.
2) I was still slightly worried about the fitment.
3) I wanted a rumble, not a rattle, and I wasn't sure how well this 3rd party offering would work in comparison to the official one.
4) How strong was it compared to the official one?
Well, as mentioned it arrived today:
Re:Q1, as you can see it's white, so it matches my DS.....he also sells pink and black ones to match your particular colour if you want.
Re:Q2, as you can see from this picture, it fits flush with the DS casing (ignore the crystal case I have the DS in).
So I tried it.
1st problem: Re:Q3, Despite this pack apparently offering similar rumble but with less noise, I felt it rattled way too much. Now I haven't got a true rumble-enabled game yet, but 42 All-Time Classics works well. When your go arrives for whatever game you're playing, a quick rumble eminates from the pack.
To cut a long story short, I simply felt it rattled too much and.....knowing me....I couldn't resist opening it up to have a quick look inside
(not only this, but re:Q4, it rumbles slightly less than the official, although you may consider this a bonus as the official rumble pack may be a bit too powerful 
....this one is less annoying, but still gives a good rumble sensation.)
It's a very simple design inside that uses a motor with an offset weight to produce the rumble effect. It SO simple that I wasn't sure I'd be able to alter anything to rid me of the annoying rattle :frown: ......
....BUT fear not, my avid readers......Gaffer, International Modder of Mystery to the rescue
.
The thing I noticed straight away was that even though the motor appears stuck down fast, the circuit board isn't, and it was this that was rattling.
So the fix I came up with started with a bit of
careful lifting, with which you can prise the circuit board up, away from the lower casing:
[Before I forget....DISCLAIMER....I take no responsibility if you decide to open up your rumble pack and end up breaking something.....]
Now roll up 4 small balls of blutack. Place these under the circuit board (as indicated by
-->) in the positions shown by
O.
Now firmly press the pcb back into place. It should resit back flush with the lower casing as intended (if it is too high, use less blutack....I've shown the blutack in the images above to give you an idea of the size I used).
As an optional extra, pinch off the smallest bit of blutack you can (about the size of three pinheads) and place it on top of the motor as indicated by
*. The motor will never get hot enough to soften the blutack, and I simply added it to fix it to the top casing to reduce possible rattles even further.
You don't have to add this tiny extra blutack if you don't want though.
Tried the pack again.....voila.....much less noise without affecting the rumble at all
However, there was still a slight cosmetic issue here. If you look at the pictures so far, whereas the DS is "glossy/lacquered", the rumble pack is matt.
Looking closely at the two reveals why:
The original cap is made of a white case with a clear "lacquer" outside it (
O = lacquer layer).
Without this layer, the 3rd party casing is simply full thickness white casing (
{) (no outer layer).
The final part of my mod therefore required the use of a sister/mother/other half. Nick some clear nail varnish from them. "Paint" the outside surface of the 3rd party rumble pack:
et voila...gloss finish has arrived
Overall a great little accessory (which can be easily improved upon) for not very much outlay. Also the fact that it rumbles slightly less than the official may be a bonus to many who find the official's rumble too intrusive {coupled to the fact that a less powerful motor will use less battery power}....overall = I also HIGHLY RECOMMEND it.
