The division between East and West Berlin is still visible from space because of their light bulbs. This photo, taken by Chris Hadfield, shows the East using sodium-vapour lamps appearing orange and the West using mercury vapour, fluorescent or LED lamps white.

An Arduino-based angle gauge with Nixie tubes: bit.ly/3t22xyB

👋Jayzon Oeve publsihed a #medical tricorder project on hackaday . This device is based upon the #ESP32 TouchDown to gather vital signs of humans without contact. Up to a range of 2 meters movement of one's Lungs an Heart can be measured. Learn more: lnkd.in/gz-ucpEf

Highly defined nanostructure arrays, such as single crystals or core-shell particles, are fabricated here using sound 🔊 The acoustic crystallization of 2D colloidal crystals produces defined nanostructure arrays over macroscopic areas The Vogel Lab 👉 ow.ly/w7Tz50LW2PW

This beautiful cover depicts periodic arrangements of plasmonic nanoparticles with tiny gaps (< 5 nm) between particles. Induced by polymer-based ligands, the gaps are key to boosting light-matter coupling Florian Schulz Learn more about this work: ow.ly/Cz6L50MciwC

Working on a portable spectrometer (288 channels) with acquisition of reflection & transmission coefficient - again. Also included: ThermoCam, audio & light FFT analysis and possibly a 100x100 2D-LIDAR. ScreenRes 800x480, ESP32s3 based. ..still a long way to go!

Some photos from last years Drum & Bass On The - Germany. The weather is going to be the same this weekend! 14:00Hrs at BRANDENBURG GATE!

It's working as intended. The displayed speed is to high, but that is a fast fix.

A new "μ-Spec nano" (v0.1) is in development. 21 channel spectrometer 260 - 940 nm, 8x8 2d LIDAR & FFT analyzer for audio. I'll need and take my time for it. Should it get a proper ftdi USB or at least a charging chip for a lipo? Should I open source it and put it on tindie?

台湾から帰ってきたらこれ。 地震対策、ちゃんとしよう。

Rev. 4 arrived (the green). Time to make some hot air.

One more sensor is working. One more (the last) sensor to debug. Also note to myself: Esp32 GPIO 12 (pin for internal flash, likes to float) dose not like a 100k pull-up. 36k is ok. With that I still can use that pin for a button state.

2"TFT is finally working and almost all sensors work and could be installed. Visualizations are coming together and I'll take my time for it.

Who the fxxk know what is this chip. Never see a hexagon chip 🥲
