Do you expect to have stock of them all in the end or do you expect to them to sell out as released? If I could pay for them as they are released but have them all ship together when ready in some sort of hold system would be OK.
Does every single project have a custom part that cannot be bought elsewhere?
It's going to be a bit of "play by ear" because I only have a few hundred switching boards and micro-controllers right now (obviously I will get more down the road). So, I will likely release the projects in batches of 50 to ensure I can provide everything at the same time.
Not all the projects will require custom pots, but no they are not available elsewhere. These were specifically made for VFE. It's not like other pots can't be subbed, though. Not all projects require custom parts, either. For instance, the second batch is likely to be the Blues King and White Horse. BK has two pots included, WH does not require custom pots.
For international shipping, I might just hard-cap it at $13 1st Class and eat any overages. We'll see. I haven't figured out all the fine details yet but I am willing to listen to suggestions.
Hope that helps!
