Thinking about building some Castle series modules I was looking into some of these also. A lot if it was for the entire Castle series, and maybe a community build or something like the Triple Function Generator.
Ordering at the first price tier is prohibitively costly for me. So It would be ideal to participate in a group buy if another one were to happen.
currently this is the price list at Mouser:
1: 4,36
10: 3,92
100: 3,20
250: 3,01
500: 2,73
1000: 2,30
I think my order will be around 70 to 100.for kits.
please add your amount to this thread, then we can see to what amount we can get!
reverselandfill: 140
x-chen: 10
marizu: 10
souka: 45?
temphill: 10 + 4046
trbsnd: 10
total: 225
I’ll have 10, please.
@reverselandfill What will be the estimated shipping costs in europe or to germany?
depends on what type of shipping you prefer and what the weight is.
I think untracked is about 4,50 to 8 euro, depending on the weight of the package
tracked shipping ranges from 8 to 17 euro
I can weigh the LM6172’s , then you will know the estimate
10x LM6172 = about 5 gram
the box = 50 gram
packaging padding = 10 to 20 gram (I think)
so 10x LM6172 will cost 5,50 untracked, 12,50 tracked
I ship from Italy
The Castle DIY series BOM, totals an amount of 29 LM6172.
For reverselandfill’s Triple Function Generator, 6 LM6172 are needed.
I’ll add two extra Castle Clock VCO, so another 4.
6 extra spares for future projects / build problems.
Total: 45 LM6172 for me.
If this thread is still relevant i would take 10 LM6172.
And btw, would it be possible to order one CD4046BE IC with those 10 LM6172? I know it would be extra work for you @reverselandfill but i forgot to order one and the shipping for one single IC is to much 
this thead is still relevant. when I do the order, I’ll contact you all.
@Temp_hill I can order a 4046 for you.
im in again, would need 10 
ok the list is updated. we are at 225 now. price mark 3,20
I’ll be ordering soon, probably next week
The order is done.
We hit the 250 price mark: 3,01 euro ex VAT
When the order is delivered , I’ll contact everybody
