NightReader-similars as an Indian government initiative December 22, 2015 - 3:39pm

NightReaders was one of the designs (next to the ComfyNetBed and the Tiles) that Vigyan Ashram wanted me to introduce during this trip to India. I did so at the Ashram. There was interest, student learned the tricks to make it (photo). Now in discussion about a follow-up of this trip I learn that the government of India has also realised that a study light makes sense.

Getting data about the need for NightReaders in India December 22, 2015 - 1:17pm

Time to introduce you to the man who engineered the complex machine with the name: ''. And who engineered as well the cluster of websites that are linked to it, resulting in the 'Demotech Hub'. His name is Chintu.

Pecha Kutcha's night for the intro of "Micro Industry" November 23, 2015 - 7:08pm

It all goes to fast! No time for reflexion, let alone for discussion about these issues with friends. So I deplore simplification and unclear description where that occurs.

However this is a splendid opportunity to go for it: introduce the idea of 'Micro Industry'. I'll do so in my Pecha Kutcha talk of tonight. I'll do so within a week in the new site

District Zero: One night in a village that sets with the sun

Children hurriedly wrap up homework, parents look up to see how far the dark is, everyone hopes they don’t have to wake up during the night. In Lakatipakana village, in Nabarangpur, the question on everyone’s lips: when will there be light?

"Learning Lights" is a solar reading light kit put together by children similar to a model building kit. When completed it demonstrates the practical application of solar technology to provide a simple solution. A reading light used for children’s study, women’s handicraft work, adult literacy.

Unite to Light November 23, 2015 - 4:29pm

What is the issue, problem, or challenge?

Kerosene lamps in rural Tanzania contribute significantly to illness and death due to indoor air pollution and fires. They limit education, without the ability to study after dark, and they introduce significant CO2 emissions. They increase poverty, a large percentage of a village household's income is spent on kerosene, and they limit commercial activities. You can break the cycle of poverty, ignorance and disease by providing affordable solar lighting to some of the world's poorest people.

How to switch off that light November 29, 2015 - 11:17pm

It is past midnight again, 1.02 AM. But a treshold has again been passed. Yesterday I tried an othher way of battery fixation. Not the thin plastic strip, s but thin rubber strips that drew the batteries nicely in the gutter-like edge where they should be.

When a TED-talk competes with the NightReader November 27, 2015 - 9:45pm

Today I took up work on the NightReader, that was left because of the TED-talk invitation that suddenly came my way. Too good an opportunity to let slip, and now also done with good response. It took a few days, that I stole from work planned the introduction of the NightReader on the Pecha Kutcha night, quite soon, Monday the 23d.

The TED-experience has wiped a big part of design grip I had. That had to be regained today. It surprised me that finding back all the small details that now matter was not that easy. But of course I did get it done.

Remember the days of the Commodore computer? October 25, 2015 - 1:54am

It had the 6502-chip. Could do a lot, al lot more then the other computers from that time. Yes, you have to be in your seventies to remember. But load of people are in their seventies and may remember the Comoodore.

If you remember the Commodore, you may also remember the Z 80 from Sinclair. Its design was smart. I loved to use it and I dreamed about taking it along in my travels to Indonesia at that time. But then at nighttime, how could I work on it, the screen readable, but the backlit keayboard not yet invented?

Salt-battery experiment November 29, 2015 - 5:12pm

This journal is about a test to find out if salt water batteries can work well for the NightReader.

That would be very welcome, for two reasons: no need for dirty leaking commercial batteries anymore plus a very instructive way of creating an electric current by the school kids that should make them at school, guided by their teacher.

First result: negative! Short cicuiting of the battery envelops could not be prevented!

What will be the solution for that?

Hy2U in Kenya October 10, 2015 - 4:54pm

Joke van den Oever and Reinder van Tijen from the dutch foundation Demotech, design for self-reliance, went to Kenya in June 2009 to teach people how to make a Hy2U handwashing device. The Hy2U solves the problem of the lack of hygiene and comfort due to the lack of piped water. With the Hy2U you can wash your hands with a small amount of clean water. It is made by the people themselves out of local materials that even the poorest people can afford. One important value of the H2yU is that people can make it the way they think it's most beautiful. Everyone deserves a beautiful bath room.

Request from Uganda October 11, 2015 - 4:27pm

Request are often dry and dull, not giving much details, not explaining the real local situation and for whom it is meant. Such request state there is plenty need, so send books. Then we answer -if possible- right away that Demotech does not distribute books, but has its websites and video's at YouTube. I also always ask if Demotech can help with anything they find in our websites or video's.

I seldom hear back.

Clean hands? Taller children! October 11, 2015 - 5:23pm

Research about Hand Washing Campaigns in Peru October 11, 2015 - 5:20pm

This article is from three years ago, just found it when archiving my mail. A sad resilt is described of large media campaigns in a few countries.

The approach with the Hy2U differs completely with what has been described below. Would that give the Hy2U a better chance to make a difference?
