There is a lot of content to migrate from the old website, it might take a while to get this page fully up to date.
For now, I’ll slowly post a lot of the old completed projects as articles on the main page, and then link them all here.

Old content aside, here’s the list of potential new projects we’re looking at!
At the moment we have no budget and i’m working on the digital media stuff in my spare time. As soon as I get some money together these kinds of projects will go ahead. – Chris
1: Test popular DIY water filters against each other .
Filters are an important part of all; hydroponics, Aquaponics, rain collection, water recycling, and potable water systems. Choosing a more efficient and simple filter design means saving many hours of cleaning the filter – over the lifetime of the system. Some designs are SO simple to make, it may be easier to make two of them in series than build a single, more complex filter for the same result.
- Research which styles of swirl filter are most commonly used, as well as other possible designs. (possibly with surveys of Aquaponics groups)
- Pick the top three popular designs, as well as make some experimental untested ones.
- Build all chosen filter designs, as cheaply as possible.
- Full photo documentation of construction for online tutorials of each filter type.
- Run all filters off the same Header Tank Manifold, feed them the same dirty water + small debris, and see what they collect.
- Observe and report the results.
- Connect the best filter for large solids to the best filter for small particles – and see how clean we can get the output.
- Observe and report the results.
- Investigate the possibility of running these as pre-filters for a low maintenance Slow Sand Filter project in the future.
2: Test DIY solar water heaters against each other .
After the success of the first two ultra-cheap solar water heater tests, this is definitely a topic that needs investigation! A simple cheap unit that heats up enough water for a few warm showers may be easy to build.
- Research which styles of DIY solar water heater are most commonly used, as well as other possible designs.
- Focus is on low DIY difficulty and low price.
- Build a few common designs, and some experimental ones. All roughly the same size in terms of solar absorber area.
- Document all construction for use in later DIY articles.
- Buy some cheap 30L+ Styrofoam boxes, one for each type of heater built.
- Observe and report the results. Water temperature taken every hour and graphed.
- Publish results.
- Consider further testing.
