Is That A Mars Habitat? A Submarine? A Spaceship? Nope: It’s Home.

[Jan Körbes], an architect living with his daughter in Berlin, specializes in recycling materials. Inspired by discarded grain silos he saw across the Netherlands, he converted one into a micro-home that you would almost expect to see on the surface of mars. The guided tour in the video below give a pretty good feel for the space station feel of the abode.

A lot of the silo house’s design was inspired by [Körbes’] childhood of growing up on boats. It’s exceptionally functional and nearly every nook and cranny of the home can be altered, repurposed, and changed back. For instance: the two pantries on the main floor used to the toilet and shower, but since the silo home is currently set up at ZK/U — Center for Arts and Urbanistics in Berlin — they make use of the facilities there instead.

True to his specialization of creative recycling , a lot of the materials for the house were either donated, or bought at a steep discount due to various reasons. For instance, the windows were a small, unpopular size for most houses but work well here. This led to an evolving design of the house as it was being built, but everything [Körbes] and his daughter need is present inside of fourteen square metres on three floors.

Under the floor on the main level is a bathtub with infrared heating — the cover doubling as the dining table with feet dangling into the tub underneath. The kitchen has a small oven, an old camp stove, and fridge — enough for two people — and the sink uses a foot-activated button so the [Körbes’] use only as much water as they need. A nearby small wood stove with an extendable wood storage basket heats the space.

The house’s electrical (including a solar battery) and water systems are tucked into the basement beside the books, keeping the heavier objects low in such a tall and narrow dwelling. Larger rainwater collection tanks (a hack we’re quite fond of) surrounding the silo house also add ballast in case of storm.

With a two metre ceiling height on the main floor and nearly as much in the bunking quarters upstairs — accessed by a climbing wall, [Körbes] says the space feels much larger than you would expect. Large enough, at least, to host a standing record of a 38-person party. It’s fun to see the ingenuity that goes into tiny living space design.

Pinging The Depths Of A Rain Barrel

Rain barrels are a great way to go green, as long as your neighborhood doesn’t frown upon them. [NikonUser]’s barrel sits up high enough that he has to climb up on an old BBQ and half-dangle from the pipe to check the water level, all the while at the risk of encountering Australian spiders.

Arachnophobia, it turns out, is a great motivator. At first, [NikonUser] dreamed up a solar-powered IoT doodad that would check the level and report the result on a web page. He battled the Feature Creep and decided to build a handheld device that pings the water level with an ultrasonic sensor and displays it on a 7-segment.

Everything is contained in a water-resistant box and driven by an Arduino Pro. The box is mounted on a piece of scrap lumber that lays across the top of the barrel. This allows the HC-SR04’s eyes to peer over the edge and send pings toward the bottom. It also helps to keep the readings consistent and the electronics from taking a swim.

Operation is simple: [NikonUser] reaches up, sets the plank across the barrel, and pushes the momentary. This activates the Arduino, which prompts the HC-SR04 to take several readings. The code averages these readings, does a little math, and displays the percentage of water remaining in the barrel.

Interested in harvesting rain water, but not sure what to do with it? You can use it for laundry, pour it in the toilet tank instead of flushing, or make an automated watering system for your garden.

Plastic Bottles Funnel Rain Into Rain Barrels

This is [Wombling’s] no-cost solution to getting rain from his gutters into a rain barrel. It is literally just a bunch of plastic water bottles chained together. At one end he uses the original cap with some holes punched in it as a sieve.

We like the concept, but find the execution a bit dubious. In heavy rain the holes in the cap will not be able to keep up and we figure your gutters are going to overflow. That may be okay depending on the grade of your landscaping, but those who value keeping their basement dry should avoid this route.

Just a bit of improvement could change all that though. We suggest making the rain barrel the sieve. Add a bowl shape to the lid with a large piece of screen in the bottom to filter out debris. Then form some type of spout on the front side of the lid to channel overflow away from the house.

The amount of waste generated by bottled water has always troubled us, which is part of the reason we featured this. We also liked seeing those plastic bottle skylights, and could swear we featured a floating plastic bottle island built in the ocean but couldn’t find the link.

Rain Barrel Irrigation System Keeps Your Plants Fed When You’re Too Busy

[Kyle Gabriel] moved into a house with a nice tract of land behind it, but due to his busy schedule he had yet to plant the garden he so desperately wanted. He worried that his hectic life and busy hours would lead to accidentally neglecting his garden, so he built a water collection and automated irrigation system to ensure that his plants never went without fresh water.

The system is fed by two large 55 gallon barrels that collect rain from his gutters. A 1/2 HP well pump is used to pressurize the collected water, which is then dispensed throughout his garden by a sprinkler. [Kyle’s] system is run from a small control box where an Arduino is used to control the pump’s schedule. At a predefined time, the Arduino turns the pump on, while monitoring the system for potential problems.

If the system starts running low on water, the Arduino triggers the valve on his spigot to open, keeping the water level above the pump inlet pipe. He also keeps an eye on pump’s outlet pressure, indefinitely disabling it before a blockage causes the pump to cycle repeatedly.

He says that the sprinkler system works quite well, and with his modular design, he can add all sorts of additional functionality in the future.
