So every time I drive my little car at night I'm filled with ungealthy rage afterwards and every time I think about what possible actions to take. This time I swore that I'd share some of my thoughts in order to help the movement gain more momentum. What comes is a collection of more or less well thought out ideas, don't take them too seriously.

1. This is not really a political fight, it's about making the world better for everyone. We don't want to take away anything from you. We should try to not get the majority of people into a defensive position but rather educate about the problems and changes in lighting.
2. Words are powerful. We need a word or wordmark that is easily understandable and that has a negative connotation without being too confrontational (like fuckyourheadlights).
3. We should be cleverly about our strategy and take into account mass psychology. A big proportion of people have annoying headlights but either don't know it or maybe don't know how to make them less annoying. Make it so that the don't feel like they are the enemy but rather part of the solution.
4. We should use official petitions or similar direct democracy tools if you have them in your country. Be clever and don't blindly start one. First gather a group of people willing to support it and have a good plan. Don't be confrontational, maybe ask for official investigation instead of bans.
5. We should try to have science investigate the issue from a psychovisual point of view. This is all about people and not dry measurements and badly done specs. Try to include drivers eye-level and cars headlight height into the studies. Include spectral issues. White light can have a very different effect than more yellow or reddish light. Petitions could urge for scientific studies instead of bans or direct changes in policy.
6. Include bike headlights, they are often as annoying as car lights. This issue highlights the alignment and height offset as parameters to the annoyingness and allows die hard car users to be included in the fight.
7. The headlights issue is an issue for people in all groups of society. Be inclusive and use all kinds of platforms or media channels to spread the word. Be sure to consider 2. and use a common branding or word mark so small communities find their ways together into a big movement.
8. Create songs, images and jokes to raise awareness of the topic. Don't point fingers but maybe make fun of people who have too bright beams without excluding them.
9. Create material to help people to better align their lights or maybe dim them. Experiment with applying transparent foil to slightly reduce strength or change tint.
10. Create a common signal to show other drivers that their lights are blinding. This could be for example: two short flashes and one long. Include this signal into your propaganda material. On bikes, remove your light and point into the eyes of the other biker until you have their attention, then point on their light. They will mostly understand the issue (unless they are dumb :/).

I hope to have brought up some interesting points for further discussion. What do you think?

A new community where people can just vent about or actually do coordinate action against the pest of ultra bright LEDs.

Someone made this nice protest song!

Blinded by the light (and not in a cool way)

Contact me if you want an mp3 or similar.

Converting an old marble table to a coffee table. I haven't worked in my shop recently and forgot how much work even the most basic thing like cutting to length is. Anyways, I'm happy how things turned out.

New bread formula discovered. The covalent bond is strong and mediated by glutrons.

(Yeah I know bro, it's di-bromine already)

I don't know what I did right but I find the scoring to be very pretty.

Bonus: the other loaves of the batch

And here the real deal:

Only crashed once :)

I made a case to protect my darts when taking them somewhere. Here are some more images. The case was made to fit a specific model and it's not very parametric till then end, so I'm afraid it's not super useful for others.

It was made in #FreeCAD 1.0 which was super smooth!

I'm designing a case for a dew-point ventilator controller to be 3d printed. The controller is implemented using arduino on an esp32. The project is based off of the code and HW implementation by Make Magazine Germany: https://github.com/MakeMagazinDE/Taupunktluefter. When starting out I was thinking this would be an easy project but it turned out that especially the lid with its lip and groove design and the parts fixations were not that easy. I'm excited to finally print it.

The file is parametric to some extent and the main footprint is based off of a master sketch. Many parts were imported as step files from grabcad. I used FreeCAD 1.0-rc1 which works like a charm for many things. Next thing I would like to do is to use the new assembly workbench. What do you think?

Manual "Exploded view",

Opaque view.

EDIT: I didn't mention the most important part. The device switches on a ventilator when the absolute moisture content outside is lower than inside a a certain room. This results in drying of the room that you ventilate like a basement with moisture issues. The dew-point acts as a proxy for measuring absolute moisture content.
