[SFDXA] Tree Top Circuits

[Bill]

Further to our e-mail of May 5th, we've received a fair bit of 
correspondence, and done some thinking. Several people have expressed 
interest in making these adapters (or possibly versions thereof).

Rather than responding for requests for information on an individual 
basis, I'll post copies of the information needed to manufacture and 
test the adapters on our website (www.treetopcircuits.com) in the coming 
weeks. This will include:

1. Schematic and pcb artwork files required to order boards from 
ExpressPCB. These will be the files we have used for production, except 
that the Treetop Circuits Canada lettering will be removed. They can be 
used as-is or edited using free software from ExpressPCB.

2. Excel Spreadsheets identifying all components, including DigiKey part 
numbers and/or manufacturers' part numbers.

3. Mechanical details for brackets, connectors, jigs, etc.

4. Information on testing. (we'll be keeping the test jigs so we can 
provide ongoing support to the adapters we built, but will include 
enough information to construct test jigs).

I'll get this pulled together and posted as soon as possible, but it may 
take a few weeks due to other commitments.

The time involved in getting into production (or even building one or 
two adapters for one's own use) is not insignificant. But the experience 
has been rewarding. I'm hoping that someone takes the plunge. It'll be 
interesting (though perhaps humbling) to see what improvements someone 
makes to my designs and methods.
