Change values of an array of pscustomobject's with a for-loop - powershell

Question

I have tried to create a array of custom objects (pscustomobject) and now i tried to change some values of the different custom objects with an for-loop. But it doesn't seem to work. Here is what i tried:
$obj = #([pscustomobject]#{value=0;type="D";used=$false})
$arr1 = #($obj) * 10
for($v = 0; $v -lt 4; $v++){
$arr1[$v].value = ($v+1)
$arr1[$v].type ="bubble"
}
The result is:
value type used
----- ---- ----
4 bubble False
4 bubble False
4 bubble False
4 bubble False
4 bubble False
4 bubble False
4 bubble False
4 bubble False
4 bubble False
4 bubble False
But i expected that the result will be:
value type used
----- ---- ----
1 bubble False
2 bubble False
3 bubble False
4 bubble False
4 D False
4 D False
4 D False
4 D False
4 D False
4 D False
This is only a snipped, and i was only trying something out. But i am a bit annoyed that i don't get it... Sorry i think it's a easy think but don't see whats worong.... i am still a PS noob... :-/
EDIT: PSv3 is used, but i think it doesn't matter...

This:
$arr1 = #($obj) * 10
is not creating 10 new objects. It created 10 references to the same object.
Note the difference if you do this:
$arr1 = 1..10 |% {[pscustomobject]#{value=0;type="D";used=$false}}
for($v = 0; $v -lt 4; $v++){
$arr1[$v].value = ($v+1)
$arr1[$v].type ="bubble"
}
$arr1
value type used
----- ---- ----
1 bubble False
2 bubble False
3 bubble False
4 bubble False
0 D False
0 D False
0 D False
0 D False
0 D False
0 D False
