Group buy is now closed. Will be contacting each of you individually to provide information on amount and account info. Payment will be for all items ordered. Shipping chargeable when collecting the items from me. To facilitate ordering, I hope to do the order by Monday 12 Oct.

Thanks everyone for your patience.

From internet exchange info, I found 1 USD = 1.39287 SGD (XE.com)

and so,

y1 is 31.15 USD = 43.3880 SGD, rounded to S$43.40

y2 is 21.15 USD = 29.4669 SGD, rounded to S$29.50

 

So, if you ordered both y1 and y2, the cost will be $72.90.

If you ordered only y2, the cost is S$29.50

 

I have pm all participants the account info today. Please try to pay me the full amount as soon as possible. I will announce the exact exchange rate charged by credit card company once I get the statement. If the exchange rate used here is out, I will work out the difference on the shipping.

o Still waiting for more participants to transfer fund.

 

o Working on list of parts to order from Farnell - will offer group buy for those building with standard parts.

Hi heady,

 

I know this is not a discussion thread. But this has aroused my interest. How much would the parts cost from AMB and digikey for a Y1 and Y2 build?

 

i will ask my friend if he can help me build one. I really have no idea on this. =(

Hi CK,

Mouz has offered to help get the acrylic panels from our usual source. How much will depend on number of people involved. From past experience, it is about S$20 per set of front and back panels.

All,

For order of the panels, we will start another group buy later.

 

For any orders of components from Digikey or Mouser. It is quite difficult to organise this as some people will prefer some components over others. What I will do will be to place what I will order for myself, in another group buy and if you want exactly the same set of components, you can participate. How's that? Otherwise, my head will spin at the possible combinations.

 

Regards
