HowTo: pxlBlck - build pxlDigit_clock with the pxlDigit PCB
The idea for the pxlDigit_PCB came to me during the construction of the pxlDigit (article here: https://nerdiy.de/howto-elektronik-sieben-segment-ziffer-pxldigit-aus-ws2812-leds-bauen/). There the pxlDigit is built from single WS2812 LED segments. For this, the LEDs must first be inserted into the 3D [...].

HowTo: Anemosens - Building a 3D printed anemometer (wind sensor)
To be honest, the idea of a 3D printable wind sensor ("anemometer" in technical jargon) has been floating around in my head for quite a long time. Initially, I would have used it as a wind sensor for one of my weather stations [...]

HowTo: PCB - Anemosens_MCU PCB assembly
With the Aenmosens_MCU board, it is possible to use Anemosens as a standalone anemometer that can be used for long-term observations in remote areas (hence the microSD card slot) or as another part of your weather station (hence the RS485 interface) [...]

HowTo: Arduino - Building the "time_timy" timer to visualize time durations
The 3D printed housing of the "pxlDigits" was not initially intended to be "just" a 7-segment display with WLAN. Originally, I turned it into a kind of timer from a two-digit 7-segment display for [...]

HowTo: Electronics - Building a seven-segment digit "pxlDigit" from WS2812 LEDs
For another project, I urgently needed a relatively large number to display a time duration. This ultimately resulted in this small "sub-project". Because with the 3D printed frame described here [...]

HowTo: pxlBlck - Display relative values as BarGraph
I started documenting the pxlBlcks (which I had been putting off for a long time) in November 2020 after Hackaday.com announced the "GoodBye 2020" challenge. (More info here: https://hackaday.io/contest/175608-goodbye-2020/details) I had used [...]
