This is an interesting community you try to create. As you, I believe in the sub-community aspects of things, concentrate on a particular topic and run a service and account(s) only around this selected topic. DYI is a good one; You mentioned you want to concentrate on the makers. But without users, the makers are making for nothing. I suggest you will include the user of the DYI in your proposition. Since the user can be anybody and on Steemit we have quite a few non-technical people, the way the DYI projects and products needs to be explained, shall be super simple. As @techtek does with his SteemPi, I suggest to promote the idea to the makers to provide clear links to parts that needs to be ordered, to websites and all. Also, the maker can offer the product ready-for-use, for a fee of course, so that the user only has to collect a package from the postal service. I know, the later is a bit beyond your definition of DYI, but that will give a large potential user base for the makers and with that it'll drive the adoption of the makers product. I call it creating bridges, and these bridges are absolutly necesary to get traction. There are quite a few large DYI webservices out there, but most of them have a similar setup like you plan to, without the possibility for the maker to ship a ready-made product and charge for it, hence those websites stays in a very small (more or less closed) community of makers and DYI.
