These 'Beach Animals' were created by Theo Jansen as a fusion of art and engineering. The kinetic structures walk on their own and get all their energy from the wind.

After 45 years of operation NASA is starting to shut down Voyager. The probes are controlled by redundant onboard computers, made of discreet CMOS and TTL ICs, and implement features such as dynamic power management and "DFU". Impressive tech from the 70s science.slashdot.org/story/22/06/21…

I am asked often what are Cyber-Physical Systems, why they are relevant and if they are a new concept. I can recommend the post below. I particularly like the reference to Cyber-Physical Security and the need to build it into the systems from the beginning.electronicdesign.com/technologies/e…

Unfortunately, Lego is discontinuing Mindstorms. I was lucky enough to learn assembly with a yellow RCX brick and robotic algorithms with Java and a NXT. Looking forward to having an alternative that can inspire future generations in tech. arstechnica.com/gadgets/2022/1…

1/n The Feynman Technique is a powerful method for learning and understanding complex concepts in physics and other fields. Named after physicist Richard Feynman, the technique helps to break down difficult concepts into simple, easy-to-understand language. A Thread 👇

When I was finishing university, around 100 years ago, I was considering specialising in robotics (and AI). In the end I pursued a different path, but I still find developments like this simply amazing!

As a kid in the 90s I had a chemistry set, a microscope, and an electronics set. These “toys” nurtured my curiosity and gave me countless hours of fun. However, I must admit I did not have something as thrilling as my own Atomic Energy Lab, which looks dangerously fun. #stem

An interesting post by Ken Shirriff dissecting a data interface module (LVDA) used in the #saturnv #rocket I especially liked the considerations on physical and thermal design, a constant struggle still these days due to the higher integration scale. righto.com/2020/04/a-circ…

Even though I am no mechanical engineer myself, I have worked with them enough to appreciate every single word in this tweet. Furthermore, I am convinced that we could find similar situations in the HW and SW fields in which I work. Really interesting write-up!

Lucky to have a Drake R-4c, Tx-4c and a few more accessories. Surprised to see it was employed for embassy communications. I remember that it was used as well for training in the Swedish civil defence. #shortwave #hf
