    Have you ever exited a dark movie theater in the middle of the afternoon and found yourself blinded by the sudden transition to bright sunlight? Etienne Leroy faces the same problem after watching a movie on his home projector and turning on the lights. Because those lights are intense and instantly come on at full brightness, the transition can be very harsh. To increase comfort, he designed a ring-shaped lamp that lightens progressively.

    ECLIPSE is a ring-shaped lamp that shines its light upon the wall onto which it is mounted. When activated, it gradually increased the brightness of the light in order to avoid a jarring transition after movie time. There are no longer any worries about hurt eyes and the lamp looks gorgeous, so it adds to the home’s decor instead of detracting from it. Best of all, ECLIPSE is easy and affordable to build if you want your own.

    The lamp’s frame is printable in small sections that should fit on most consumer 3D printers. Illumination comes from a strip of “warm white” LEDs, though it would be easy to substitute another color or even RGB LEDs. An Arduino Nano controls those LEDs, increasing brightness slowly over a set period of time. It uses an infrared receiver module, so users can take advantage of the remotes they already own and have handy to turn the ECLIPSE lamp on. It will work with any infrared remote and the user only needs to decode the specific code sent by their remote when they press the desired button.

     Firstly, I’d like to apologise for rickrolling you all yesterday. I would LIKE to, but I can’t — it was just too funny to witness.

    But as I’m now somewhat more alive and mobile, here’s a proper blog post about proper things. And today’s proper thing is these awesome Raspberry Pi–powered dance costumes from students at a German secondary school:

    In the final two years at German gymnasiums (the highest one of our secondary school types), every student has to do a (graded) practical group project. Our school is known for its superb dancing groups, which are formed of one third of the students (voluntarily!), so our computer science teacher suggested to make animated costumes for our big dancing project at the end of the school year. Around 15 students chose this project, firstly because the title sounded cool and secondly because of the nice teacher 😉.

    Let me just say how lovely it is that students decided to take part in a task because of how nice the teacher is. If you’re a nice teacher, congratulations!

    The students initially tried using Arduinos and LED strips for their costumes. After some failed attempts, they instead opted for a Raspberry Pi Zero WH and side-emitting fibre connected to single RGB LEDs — and the result is rather marvellous.

    To power the LEDs, we then had to shift the voltage up from the 3.3V logic level to 12V. For this, we constructed a board to hold all the needed components. At its heart, there are three ULN2803A to provide enough transistors at the smallest possible space still allowing hand-soldering.

    Using pulse-width modulation (PWM), the students were able to control the colour of their lights freely. The rest of the code was written during after-school meetups; an excerpt can be found here, along with a complete write-up of the project.

    I’m now going to hand this blog post over to our copy editor, Janina, who is going to write up a translated version of the above in German. Janina, over to you…

    You Won’t Believe What Scientists Say Blue Light Can Do For Humans

    Still have a morning ritual of drinking a few cups of Joe? Well, researchers at Mid Sweden University compared the effects of caffeine and blue light on the brain and found them both to have a positive effect. Here’s the kicker, people who were exposed to blue light performed better on tests of brain function that included a distraction.

    Here’s what one researcher has to say: „The same distraction, however, proved too much for caffeine users, who performed poorly. Blue light and caffeine demonstrated distinct effects on aspects of psychomotor function. The study builds on research that suggests blue light can improve cognitive abilities such as memory, alertness and reaction time. Although harmless to tissue, blue light is strong enough to trigger biological effects in the body, and it’s being used increasingly for a range of medical treatments.“
