Basics 03: Purchase Plans for [The_Cube]... Cheaply!

Click on the images to see the whole set...














For the time being (other things are taking my time just now), the drawing set for [The_Cube] is still in a draft and unfinished state: it does not include what would be a final drawing or two, describing the gasket for the top panel. (I did not complete the research on that, which would have included pressure tests and the like. My bet would have been on a squeezed on gasket using silicone grease— not petroleum based— but only testing can provide a solid basis for a final choice. That is how every other part of it was designed.)

Still, I think many of you are very clever, and should be able to figure out the few things remaining to be described-in-detail on your own. I intend to sell the completed set of plans for $150, but I've decided to sell this nearly completed draft set of plans at a better than 40% discount, for $85.

This drawing set for [The_Cube] has 58 full-color pages, genned out of Autodesk Inventor in Super-B size (13x19). There's a lot of detail. and per our present plans, when the plans are ready for prime time, that set will will cost $150.

It’s your call regarding whether you think that’s too much money. For my part, I invested 3 solid years in this project, paying for the materials, doing the experiments, creating the drawings, testing ideas, creating software, and just by the way washing the dishes, et al…. Yes, it is not entire and complete, but it is [really, nearly, almost] the world’s first temperate-climate, kittable, shippable, agitated, optionally instrumented, low-cost, DIY digester, with effluent recirculation? And with the drawing set in hand, you can build one or a hundred.

So what’s this deal I mentioned? This: While the drawing set is still in draft, we are offering to sell you this nearly-complete set of plans (plus labels and the parts list Excel spreadsheet) for $85, plus postage ($10 for relaxed shipping of the plans & the labels within the US) and when the plans are finished and sparkling— but honestly, we have to say if that happens— we will send you the completed set.... at no further cost.

You can see a complete set of the pages in low-rez here.

The way we see it, you get

  • a solid preview and a very detailed look at [The_Cube],
  • a better than 45% discount, and
  • 1.9 (almost two) complete sets of plans.
  • (Did I mention the discount?)

How can you beat it?

Sounds good. But what's missing?

To be as specific as possible, of the 15 primary sub-assemblies that make up [The_Cube], the drawing set is complete with regard to all but one (the top panel), and the instructions are incomplete regarding the last few finishing touches when installing the sump, and for the installation of the last three sub-assemblies that are put on [The_Cube]: the front, back and top panel. That's it.

The complete list of sub-assemblies which make up the entire [Cube], by the way, is:

  1. The stand or base for [The_Cube], in ‘standard’ and ‘professional’ versions.
  2. The panel right, which hosts the GCS system (below) and abuts the sump.
  3. The panel left, a rather plain but wholesome panel.
  4. The top square, which knits the tops of the four side panels together at the, uh... top.
  5. The GCS, gas collection (and distribution) system, also providing instrumentation access.
  6. The sump (for hot water).
  7. The pump/heater, fitting inside the sump.
  8. The HEX-by-4, comprised of four Heat Exchange units or panels.
  9. The agitator, which will turn slowly as biogas is produced and bubbles up into it, or turn more rapidly via recirculated biogas (GCS).
  10. The effluent pipe, which drains slurry pushed out by incoming slurry.
  11. The panel front, which supports the agitator axis (inside), through which the effluent pipe and the recirculation system (below) pass, and, when using the standard base, which includes a drain.
  12. The panel back, another plain/wholesome side, which also supports the agitator axis, and which therefore is very slightly more interesting than the very dull and boring panel left. (Sorry about that, panel left. My apologies, panel back.)
  13. The panel top, where the inlet funnel is.
  14. The instrumentation box (for those digesters where instrumentation is desired), and which also protects the gas recirculation pump and helps keep the moist gas in the GCS pipes from freezing.
  15. The jigs collection. (Manufacture of [The_Cube] makes good use of jigs.)
