You have two options:
- build it yourself
- Buy it
I occasionally sell boards and/or kits. Sometimes even completely pre-soldered and tested systems. But due to the open nature, others can sell boards and kits themselves. Here is a list of people that sell PHCC boards/kits/systems:
- 'AiRdAncE' has an online store here: http://www.checksix.nl/catalog/
- 'asekeris' has an online store here: http://www.phccparts.nl/
- Also check the forum threads about ordering boards/kits at http://www.viperpits.org/smf/index.php?board=73.0
All the designs are freely available for download, so you can etch your own boards, or have the boards professionally made at a PCB production facility. Or you can buy boards at one of the above mentioned vendors. Then buy all the parts (see the Bill of Materials files for each board) and solder everything together. Board assembly tutorials are available for several boards.
Assembly Services by Others
To have your kit built by others (usually for a fee), look below for offers.
Another option for those who are not experienced or uncomfortable with soldering PCBs is being offered by John Steensen (jrsteensen) on viperpits.org. (http://www.viperpits.org/smf/index.php?topic=4222.0) He is offering Assembly Services. You order your PCBs and components, and he will solder them together and test the boards and return them to you for a nominal fee. All details (price/contact info/etc.) can be found in the above thread.
