Pump alternative and the fan motor involved


Relaxing in a long chair, Tibor considered the problem of lifting water in general, and a completely different solution assembled in his mind, that is a bucket chain made from simple materials. This is the initial draft that contains already specific solution ideas for the pouring of the water etc.
For supplying the driving force to the buckets, a standard computer fan could be exploited as a motor (removing the blades; using the outside rotor directly as a pulley). The pictured fan develops an equivalent of 10-20 grams on that circumference and runs at around 20 revolutions per second…


Tibor's notebook - volume 2 - Transistor timer circuit


This is Tibor's second notebook on which he started working back at home. The work shown originated in the time between christmas and exam preparations. It is about reconstructing the electronic timer circuit for the rope pump's magnets, using only transistors instead of integrated circuits. This is not only for cost and availability reasons (in the new design, *any* type of small NPN transistor from scrap etc. should work), but also because those three-legged transistors allow more accessible ways of assembling the circuit, going without circuit boards and maybe even without soldering.

Tibor's Notebook - volume 1


Scans of the complete notebook (laboratory journal etc.) that Tibor created during his 3-week stay in Maastricht (25 Aug - 14 Sep 2015). This album now contains all the pages of the notebook (pages 46-47 have been used for an unrelated LBB project), some related loose sheets are waiting to be converted and uploaded. To be done by an administrator: Squeeze the thumbnail section (make it scrolling) or move this article down in the "Media gallery" page.

Create Food Security in a Changing Climate


Action to address inequality in food systems

Today, October 13th, this message came in Demotech's postbox. It is in support of Demotech's project for Vertical Gardening, called Green for Equity. The urgency is again greater then known before. Reason to press ahead with this project. Recent result is

- the hands-on workshop for Maastricht UCM-students

- design and prototyping of the cloth pump, specially the construction of electro-magnets as the crucial part of this cloth pump.

There would be NO stagnation in ideas or plans for the…

Green Window


One day small plants, small compared to the construction of trays, suspending wires and water tanks for the drip. Now all that technology is hardly visible anymore. Just green, wild also, not much care give to guide plants or trim them.

Yet learned a lot about how it can work, actually how it works with the sand bed under the plant roots, first enveloped with netting, now with neat square plastic cups. Describing how this jungle developed will be done in a blog. Now pictures that are avallable should be posted on this site.

Social Entrepreneurship in Demotech


Hello people!

It's Lukasz here! After 3 week long break from service in Demotech I am back again! Last week we spent time on doing more flower bags for our nice green wall hanged on the window. But today I would like to share my statement about social entrepreneurship in Demotech. What is exactly social entrepreneurship? It's pursuing an innovative idea with big potential to solve a community problem. People who are passionate about taking risk and effort to make some positive changes in our society. To create new solution, or service, or a new approach for the problem. It's powered…


Creating flowerbags for Green walls


Hello, readers!

Here's Lukasz again! Before I get to the main point, I have to share with you some information. Rest of my group has quit our project. Yea, it's really sad. But in other hand quite better for me, because I'm kind of individual. I did not figure out what was the purpose to leave. I have heard that they "weren't motivated enough" or something like that. Well, I don't know what to think about it.

Ok, enough! Let's get to the main point of this blog, creating simple flower bags for our Green Walls! I will explain step by step the process of making as easy as I can…


The first days in Demotech and a little reflection


Hello all readers!

My name is Lukasz and I'm one of four people group from the UWC Maastricht (link is external). Firstly, I want to introduce myself a little. My name you already know :) I'm 16 years old and I came from Poland. Now I live in Hoensbroek, quite close to here. I will spend three years here, in Netherlands and I believe that this three years will be unforgettable for me :)

I'm working with Demotech as my service learning activity provided by the school. I'm here to learn such basic and advanced…


On the way


Dear all,

In just a week I got used to quite some things in 'Africa on bicycle distance' a.k.a Demotech. I became familiar with Reinder's intriguing brainwaves, his dancemoves, his frustrations, his sympathy and his enthusiasm. I learnt how to light the stove and feed it with wood, know where to find tools and feel free to eat as much banana's as I want. Reinder is taking good care of me and I feel more and more at home. I meet him daily and feel more connected to the green4equity project we are working on. Nowadays I mostly leave the place with dirty hands, which is a good sign…


My first day


Dear peeps,

Today I stepped into the world of the legendaric Reinder, and came in touch with his ideas and the vision of Demotech.
My name is Jorien and I am a curious being in love with life. I would like to learn how to create any kind of useful stuff.

Reinder introduced me in his innovative method of crowd-learning, a fast learning process, which ignited a fire of enthusiasm in me. This is what we need, new systems which are designed to contribute to a sustainable life on earth and collaboration between people. Instead of destruction and violence, such systems stimulate…
