The FarmBot Genesis Brings Precision Agriculture To Your Own Backyard - Modern Farmer

The FarmBot Genesis Brings Precision Agriculture To Your Own Backyard - Modern Farmer | High Hops For Yeast | Scoop.it
Developed by a team of three from California, the kit is an autonomous machine that’s installed atop and around a small garden—in your backyard, on a rooftop, or inside a greenhouse or lab. Once built, Genesis performs nearly the entire gardening process prior to harvesting, including planting the seeds, watering each plant precisely and on a set schedule, monitoring conditions, and pulverizing pesky weeds.
Vivalist's insight:
This tool looks really promising.

FarmBot is powered by a Raspberry Pi 3, Arduino Mega 2560, and RAMPS 1.4 shield.

All of FarmBot’s plastic components are designed to be 3D printed with hobby level FDM printers.

It is fully open source and you can buy the kit from them for about 3000$.

It comes wih a unique yet versatile head called the The Universal Tool Mount "Featuring 12 electrical connections, three liquid/gas lines, and magnetic coupling."
This mount is completed with several useful tools such as soil sensor, vaccum seeder, weeder (hurrah!),watering system, camera for which design documents are available... and it also allow users to create additional ones

More info

And because they are cool like that, they provide step-by-step instructions if you want to "add-on and mod" this already cool gardening robot:

Powering the system with solar

Use of rain water

Controlling a greenhouse environment with peripherals (using fans, automated exhaust flaps, lights, and even heating elements) that you plug to the Arduino

You can also contribute to the climate monitoring adventure with Weather Underground [https://www.wunderground.com/]

Pedal powered farms and factories: the forgotten future of the stationary bicycle

Pedal powered farms and factories: the forgotten future of the stationary bicycle | High Hops For Yeast | Scoop.it

If we boost the research on pedal powered technology - trying to make up for seven decades of lost opportunities - and steer it in the right direction, pedals and cranks could make an important contribution to running a post-carbon society that maintains many of the comforts of a modern life.


The possibilities of pedal power largely exceed the use of the bicycle. One way to solve the large energy losses of pedal power generators is not to produce electricity at all but power devices mechanically, whenever possible.


Another way - the only way for devices that cannot be powered via a direct mechanical connection because they do not rely on rotary motion - is to make the generation of electricity more efficient. This can be done by building a pedal powered generator from scratch instead of using a road bicycle, or by ditching one or several electronic components in the power transmission chain.


All approaches can be combined, resulting in a pedal power unit that can power a multitude of mechanical devices and generate electricity comparatively efficiently.

Vivalist's insight:
This excellent overview of pdeal power by Low Tech Magazine is a good opportunity to aggregate in one post some the most comprehensive ressources I found online.

As it is often the case in terms of simple and efficient low tech principles put to use in agriculture, the FAO did publish a review of "water lifting devices"
http://www.fao.org/docrep/010/ah810e/AH810E00.htm#Contents

I aslo found the Practical Solutions' guide "Human & Animal Powered Water-Lifting Devices for Irrigation" very insightful. This organization's website is packed with valuable resources for low tech agriculture methods.
https://answers.practicalaction.org/our-resources/item/human-animal-powered-water-lifting-devices-for-irrigation

And if you'd just like to get a rapid overview of the basic principles, there is this 5 pagers
http://pnrsolution.org/Datacenter/Vol3/Issue1/72.pdf

or for hand powered water lifting devices, there is is short read
http://waterbuckpump.com/2014/07/16/hand-water-pump/

and even come experimental ways of lifting water without a pump https://www.youtube.com/watch?v=9WT8JIUCjjg

Gust MEES's curator insight, January 30, 6:24 PM
Pine64 has released a budget-friendly single-board computer with the high-powered Rockchip RK3399 system on chip (SoC).

Available from around $60, the RockPro64 board comes in two flavors, either with the hexa-core RK3399 SoC or the RK3399Pro, Rockchip's first "artificial-intelligence processor". Unveiled at CES 2018, it combines a CPU, GPU, and neural-network processing unit (NPU).

As noted by CNX-Software, a number of RK3999-based boards have been released in the past week but, priced at around $200 each, they've been aimed at business customers rather than home developers.

The RockPro64 with 2GB of RAM will cost between $59 and $65 and will be available from March, while the RockPro64-AI will cost $99 but won't be available until August 1, according to Pine64.

CU Boulder engineers have developed an innovative bio-manufacturing process that uses [a fast-growing fungus, Neurospora crassa] cultivated in brewery wastewater to create the carbon-based materials needed to make energy storage cells.

Vivalist's insight:
Interesting discovery by some academic researchers. They plan on running a pilot program with Avery Brewing in Boulder in order to explore the potential further. Scalability and costs could be limiting factors.

How to build a Wood-Gasifier /// Instructables

How to build a Wood-Gasifier /// Instructables | High Hops For Yeast | Scoop.it

In this Instructable I will be showing you the steps I used to build my Wood/Biomass Gasifier. It was really a fun project and I would encourage anyone serious about preparedness to build one.


Essentially all gasification is a form of incomplete combustion, heat from the burning solid fuel creates gases which are unable to burn completely because of the insufficient amounts of oxygen from the available supply of air.


It then filters those gasses (which is by weight: 20% hydrogen, 20% carbon monoxide, 50 to 60% nitrogen, and a little bit of methane) And you can really use any kind of Biomass (organic material) that will burn. You can even use things like paper, coal, peat, and lignite.


You can then use that filtered gas to run any thing from a generator to a car. So now that you have a basic understanding of what gasification is, lets get down to the build!!!

Vivalist's insight:
As the author mentioned in his intro of this step-by-step guide to building a wood gasifier, adding a condenser after the filter in order to get moisture out of the gas.

How to Grow, Harvest, and Eat Yacon

How to Grow, Harvest, and Eat Yacon | High Hops For Yeast | Scoop.it

Yacon is South American tuber, and it has a crunchy, juicy texture. It is also called a ground apple or a ground pear.

The tuber contains fructo-oligosaccharide which is an indigestible polysaccharide made up of fructose. So you get all the benefits of the sweet taste but none of the calories as they pass through the human digestive tract unmetabolised.


It is a perennial daisy with clusters of yellow flowers (see above) that grows to about one metre plus.

It has furry leaves that are nutritious and can becooked like spinach as a green. The leaves contain quantities of protocatechuic, chlorogenic, caffeic, and ferulic acids, and these have prebiotic and antioxidant properties. You can also make the leaves into a tea

Vivalist's insight:
Another perennial plant that I would gladly welcome in my forest garden. 

You start from "crowns" planted in pots until frost is gone, then after a full growing season, you could let the plant get hit by frost as it is said to increase the sweetness in the tuber.

When harvesting, you separate the crowns from the tubers and place the former in a sack of damp compost stored in a frost-free area to plant the next year.
 
Then you place the tuber on a sunny windowmill for a couple of weeks in order to allow them to sweeten. Then you can store them in a dark and cool place.

Yacon is very productive and it is said to increase yield year-on-year as the plant adapts to your local environment... I love this particular point :)

This species was specifically chosen because of its voracious appetite, with one larvae able to quickly process half a gram of organic matter per day.

In fact, the larvae can eat a wide variety of household waste, including rotting fruit, vegetables, meats and, if desperately in need, manure, and quickly convert it to a rich source of fats, oils, amino acids, calcium and protein.

Management in Aquaponics: Comparison of Three Approaches for Cultivating Lettuce, Mint and Mushroom Herb

Management in Aquaponics: Comparison of Three Approaches for Cultivating Lettuce, Mint and Mushroom Herb | High Hops For Yeast | Scoop.it
Nutrients that are contained in aquaculture effluent may not supply sufficient levels of nutrients for proper plant development and growth in hydroponics; therefore, they need to be supplemented.
To determine the required level of supplementation, three identical aquaponic systems (A, B, and C) and one hydroponic system (D) were stocked with lettuce, mint, and mushroom herbs.
The aquaponic systems were stocked with Nile tilapia. System A only received nutrients derived from fish feed; system B received nutrients from fish feed as well as weekly supplements of micronutrients and Fe; system C received the same nutrients as B, with weekly supplements of the macronutrients, P and K; in system D, a hydroponic inorganic solution containing N, Ca, and the same nutrients as system C was added weekly.

Lettuce achieved the highest yields in system C, mint in system B, and mushroom herb in systems A and B.
The present study demonstrated that the nutritional requirements of the mint and mushroom herb make them suitable for aquaponic farming because they require low levels of supplement addition, and hence little management effort, resulting in minimal cost increases. While the addition of supplements accelerated the lettuce growth (Systems B, C), and even surpassed the growth in hydroponic (System C vs. D), the nutritional quality (polyphenols, nitrate content) was better without supplementation.

Here's a quick run down of what we'll cover in this article, so you can decide if it's for you or not:

Why Mushrooms are a great crop to grow
Why they're perfect for small-scale local food production
How many mushrooms can be grown in a small unused space
Why low-tech mushroom farming is the easiest method
Some ideas for generating income from mushrooms
Vivalist's insight:
A very well documented piece on mushroom farming. Every steps are described with a focus on processes and structures in order to really provide a solid kowledge starter kit for future growers.

There are 3 main stages to the growing process, each requiring a different space:

Stage 1: Mixing & Inoculation - where the substrate ingredients & mushroom spawn are mixed and bagged (more on this process in a minute)

Stage 2: Incubation - where the grow bags are left in a warm dark space for the spawn to grow throughout the bag

Stage 3: Fruiting - where the colonised bag is exposed to fresh air, humidity and a little light which causes the mushrooms to ‘fruit’.

Pendant 3 ans, cette machine autonome va être testée par Laurent Dallier et sa fille Mélanie, exploitants à Chatignonville. Elle les aidera pour enlever les mauvaises herbes et transporter les récoltes. Cet assistant autonome a été développé par une société toulousaine, Naïo Technologies, il y a 5 ans. 

Le robot Oz est le fruit d’une convention signée entre le conseil régional et les chambres d’agriculture d’Ile-de-France. Ces deux organismes, accompagnés par Groupama Val-de-Loire, ont lancé une politique de soutien à l’innovation. Ils voient en ce petit robot électrique de moins d’un mètre de long, 40 cm de large et de 120 kg, équipé d’un laser et de caméras détectrices, la possibilité d’améliorer les conditions de travail des exploitants. Le robot Oz réduit la pénibilité des tâches des maraîchers, il leur fait gagner du temps et il respecte l’environnement car il contribue à utiliser moins de produits phytosanitaires.

Three Sisters Garden: Corn, Beans, Squash - A Native American tradition

Three Sisters Garden: Corn, Beans, Squash - A Native American tradition | High Hops For Yeast | Scoop.it
Corn provides a natural pole for bean vines to climb. Beans fix nitrogen on their roots, improving the overall fertility of the plot by providing nitrogen to the following years corn. Bean vines also help stabilize the corn plants, making them less vulnerable to blowing over in the wind. Shallow-rooted squash vines become a living mulch, shading emerging weeds and preventing soil moisture from evaporating, thereby improving the overall crops chances of survival in dry years. Spiny squash plants also help discourage predators from approaching the corn and beans. The large amount of crop residue from this planting combination can be incorporated back into the soil at the end of the season, to build up the organic matter and improve its structure.

Corn, beans and squash also complement each other nutritionally. Corn provides carbohydrates, the dried beans are rich in protein, balancing the lack of necessary amino acids found in corn. Finally, squash yields both vitamins from the fruit and healthful, delicious oil from the seeds.
