Going London!

This year my traditional Spring Trip leads me to London! I am invited to have a presentation and optionally a workshop on liberatory technology, during a conference held at Kings College ( Thanks to my friend’s hospitality I will be able to stay longer, so the current plan is that I arrive in the afternoon/evening of 4.04 and leave sometime at 14th. Between these dates I am going to run the conference events, meet friends from the UK (funding permitting) and do other things FB doesn’t need to know about.

So, if you want to meet me there, just join the event and we shall coordinate somehow.

It is going to be FUN!


As usually, the budget is next to nil.  As for now, I have fixed:
– Shelter for the whole time I stay, thanks to Z. and his family.
– 50 quid from the organizers of the conference, which will probably cover my Oyster card.

I am definitively short:
~ 120 Euro for the round trip air tickets (RyanAir).
~ 30-50 Euro of reserve for extravagances like a cup of tea.
[Food I hope to get for free — all suggestions will be appreciated]

My kind request to you, folks, is: If you can buy me an air tickets (can be one way — at least TO London), please pm me and we will arrange that.

Other than that, just find the fundraising section here to the right and drop something in. You will be satisfied, I promise.

Simple solar power

for the Lighthouse camp on Lesvos Island

per request of Pia Henrietta Kekäläinen, 3.03.2016

1. Problem definition1

The volunteer-managed camp (see video at is an off-grid location. They have several local solar powered lamps, but the whole camp area lighting is only powered by the genset. It means costs and it makes problems when the immediate light is needed. So the solution is needed to have the „one switch” installation, able to bring light to the whole camp area without the need to start the genset. Continue reading Simple solar power

Solar Technology Workshop Level 1

Solar heating in your kitchen

1. Introduction

The goal of the workshop is to give people initial understanding of the physics behind the solar heating and to help them start building their own solar devices of practical value. Planned for a weekend (1½ day, or 12 h in two sessions) it provides a lot of time for socializing, discussion and slow, thoughtful groupwork.

As a result of the workshop, participants will understand the way the Sun is heating us all, how it changes during the day/night and yearly cycle and how this energy can be harnessed. Continue reading Solar Technology Workshop Level 1

Possible ways of grassroots integration

for new settlers: migrants, asylum seekers and refugees in Europe


schroedinger-immigrantFor the sake of this document, „grassroots integration” is understood as a way of cooperation with „new settlers1”, who just arrived to Europe, to restore their empowerment with the help of their friends and allies among European societies. This is the logical extension of volunteer help in their transit from outside of Europe to their chosen (or, recently, forced) destinations.

The goal of this activity is to make as many new settlers as possible independent, accomplished and happy members of their local communities. Continue reading Possible ways of grassroots integration

Drill Press a’la Roustique. Part 1

First of all: two small clamps, 4,50 Eur each are real game changers. And a relief (I know, sounds contradictory).

So, I decided to make a drill press. My old 12 V Black and Decker strapped to a plank, sliding up and down on a wooden support, powered by an old (pre-ATX) computer power supply. That was the plan.

The second part went fishing, as the power supply is FUBAR and the new (old technology is costly) would cost some 50 Eur. So the drill has to wait for another opportunity.

But still, seeing that the cheapest 230V drill is available at a rock-bottom price of 28 Eur, I decided to go ahead.

Basically, the photostory tells it all. Due credit goes to, where I learned XYZ construction nodes. I love them.
