I am not in the business of making or selling kits. All my make projects are currently released under Creative Commons Attribution-ShareAlike 3.0 License. I try to support Open Source Hardware and I will put up the source code, parts list, Eagle files, and link to PCBs on BatchPCB whenever I have time. But I am curious if there is interest in me/someone offering a kit of any of these projects. E-mail me: larsi.org(at)gmail.com
