MINISTRY OF INFRASTRUCTURE AND WATER STATEMENT, Head of the Road Safety Department sees no objection to a luminous white cane

I received this in response to my letter to the Ministry of Infrastructure and Water Management:

I hereby respond to your question to the National Government Information about the white cane that you use as a visually impaired person when you participate in traffic. You ask if you can use a cane that is luminous, because the ordinary white cane is not visible in the dark and in bad weather.

Thank you for putting this question to me. It is very unfortunate to hear that you have been hit and I understand that you are looking for ways to prevent this in the future.

The white cane should contribute to your safety in traffic. In Article 49, paragraph 1, of the 1990 Traffic Rules and Signs Regulations ( ) state: “Drivers must let the blind, equipped with a white cane with one or more red rings, and let all persons with difficulty move ahead.” Thanks to the blind guide cane, other road users see that a blind person is approaching and they must let him go.

The legislation does not further define the white cane with one or more red rings, the white cane for the blind. We must therefore start from common usage. A white cane that emits white light and has one or more red rings still looks like a “white cane with one or more red rings”. From “one or more” you could infer that the legislator would not want to see just one design as a “white cane for the blind”.

It is super nice to know this!

Heaven of God Ideas

Prototype Mondkapje

Crises and accidents are a cultural pressure cooker. They invite innovation. Super interesting!

For example, many individuals and maker communities are currently alleviating problems in healthcare. The famous issue of mouth masks and respirators, for example, is a matter of great concern. Suddenly there are too few. That is why people are busy devising alternatives themselves. Attempts can lead to innovation, especially by soaking together. Time will tell which attempts were successful and which go to Heaven of Good Ideas. You only know that afterwards.

If it turned out not to be such a good idea, you will enter a new phase. What do you learn from the feedback? Is it a matter of improving the elaboration of the idea to make it good, or can you send the idea to Heaven of Good Ideas?

The Heaven of Good Ideas has a predominantly positive atmosphere. So many attempts to improve the fate of people and animals, so much inventiveness, so much love!

Is there reason to be sad when a good idea turns out to be not so good? Is it bad to send an idea to heaven?
Yes and no.
Yes, because how nice would it have been if the problem with this invention had been solved?
No, because it is better to try seriously than to think in advance that it is not possible. We have learned new things. We may have met new people in the process and new ideas will bubble up. Only when we make it and try it out will we know if it can work. You only know if it is working properly if you have it tested.

I assume that the hard labor of Makers during this Corona crisis will yield so many usable and easy-to-produce masks and respirators that in the near future all of humanity will be better protected against subsequent outbreaks of viral respiratory infections. Also in economically disadvantaged areas.

Before that protection is actually there, a lot of iterations and “failures” and other learning moments are needed. We all need these. In this context it is therefore an honor if a mask goes to a gallery in the Heaven of Good Ideas.

I wish all Makers inspiration and success.
Thank you in advance for your hard work!

Nous maintiendrons!

Holman competition

Crossing the street with a LightupCane

Crossing the street with a LightupCane

Hello dear supporters,

I tried to make a video with a mild cold to participate in the Holman competition. The Holman Foundation is based in the United States, and they promote that blind and partially sighted people do interesting things. Well, I am of course still busy with the Marchena LightupCane.

Something didn’t go quite right, so that movie is (unfortunately) called “mijn film”, my movie. Yes, it will eventually be, well, just watch it.

Do you want to vote for my video?
How? Like the video

Presentation LightupCane at Symposium

Presentatie Lightupcane op Symposium

Presentatie Lightupcane op Symposium

Two teams of students gave a joint presentation about the DIY version of the Lightupcane. They have made it suitable for the blind. When the light comes on, or goes out, the blind user receives a vibrating and sound signal. If the cane falls it will beep until it is picked up. If it needs to be charged, we will receive a signal.
Super handy!

The intention is that second-year students of electrical engineering make the electronics smaller, so that the electronics should fit into any handle.
