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

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.

Bubble bath, or Return of The Valentine Box

Episode 2…

Second only to the duct tape, polyurethane foam becomes my preferred tool and material, by far besting chewing gum so widely used as an improvised …everything, actually.

But surely, I will have to quit ready-made one, in pressurised containers. Great, if you spend the whole can at once, they tend to  clog with dried foam and sometimes you can only trash the half-full can, still worth few Euros — or hack it seriously, with a bit of a personal risk.
