Da sich sehr viele Besucher auf dem #37c3 für meine #LED-Sterne interessiert haben die beim @c3pb am #Dodekaeder hingen, wollte ich hier noch mal schreiben, unter welchen Suchbegriff man die kleinen LED-Stäbe bei gängigen Händlern findet: "meteor shower cob led pcb".
Um daraus einen Stern zu machen benötigt es dann nur noch etwas Klingeldraht und Geduld beim Löten. Welcher IC da drauf ist kann man leider nicht erkennen, aber vielleicht baue ich irgendwann™ mal eine RGB-Variante von den Dingern.
A custom component for esphome to interface with IKEA's Frekvens Cube and Obegränsad panel.
Osmocom SIMtrace 2 is a software, firmware and hardware system for passively tracing SIM-ME communication between the SIM card and the mobile phone, and remote SIM operation.
While it was designed for SIM-ME communication, it supports all ISO 7816 smart-cards using the T=0 protocol (the most common case).
It is a followup of the SIMtrace project, providing more functionalities (e.g. remote SIM operation) and supporting multiple boards (e.g. SIMtrace with SAM3S, sysmoQMOD).
Mit unseren Bausätzen möchten wir eine Möglichkeit bieten das Löten zu lernen oder seine Lötkenntnisse an tollen Beispielen zu erweitern. Vom einfachen "I Can Solder" Bausatz mit 3 LEDs bis hin zu komplexen Schaltungen mit SMD Bauteilen ist hier alles dabei. All unsere Lötbausätze kommen mit allen benötigten Bauteilen und einer Anleitung.
The basic case consists of the two parts: front and back, which can be srewed together by using either standard M3 hex nuts or heat inserts.

Micro SD box
Tips:
You can print it standing, no need to rotate (and no need for supports).
You can adjust the tightness by adjusting the filament flow option in your slicer software.
Maybe you know how to solder a bit, but you suck at it. Or it's frustrating and never comes out nice and you hate it.
Here's how to make it enjoyable, and get good results as a side effect.
But [Zonglin Li] has recently wrapped up a project which shows that e-ink has at least one more use case: personal calendars. You can get way with only updating the screen once a day so the refresh rate won’t matter, and the rest of the time it’s going to be static anyway so you might as well enjoy the energy savings of leaving the screen off. With a Raspberry Pi behind the scenes pulling data from the Internet, it can populate the calendar with everything from your personal schedule to when your favorite podcast drops.
A snap-together derivative of Mattraptions' Mini Desk Lamp.
Modified by Skimbal to use Tony Buser's snap fittings.
Instructions

Snap the arm togeather using the images as a guide.
Snap the Arm into the base.
Snap the Lamp onto the arm.
Add a light.
Smile.
Here's another iteration on the Zero Terminal projects I've been working on for a few years. For those of you who haven't seen them, I've been trying to design the most usable all in one Pi Zero computer out there.
This version departs a little from the previous ones, as it is more focused on modularity, and forgoes a keyboard as standard, though it is possible to add one, as I'll show you in a bit. The goal here was to create something very versatile, allowing for all sorts of use cases to unlock the Zero's potential. Anyways, let's take a look at it.
I have been running a full IBM System/370 Mainframe on a $20 Raspberry Pi Zero for ~5 months. Thousands of lines of COBOL and HLASM running flawless. Tested an entire bank’s mainframe COBOL on it.
Since 2012, the Raspberry Pi nano computer has become an increasingly important part of the DIY and « maker » community. The increase in power of the Raspberry Pi over the years offers very interesting possibilities for radio amateurs. Indeed, it allows not to permanently monopolize a PC in the decoding of frames with software like WSJT-X, FLDIGI, etc…, without forgetting the possibility to control the Raspberry Pi remotely and thus to be able to work outside the radio shack as I can sometimes do on my couch. Moreover, this nano computer is now widely used in any Hotspot (DMR or D-STAR).
Researchers from Intel Labs have developed an open-source 3D printed smart robot that it is possible to build for less than $50.
Once combined with a modern smartphone, the additive bot is able to navigate autonomously, and its real-time sensing capabilities enable it to conduct recon tasks such as following people. The PLA-based Openbot has also been designed to be easy to build too, and its STL files have been made freely available online. By making their design public, the researchers hope that creators will tinker with and improve their robot to continue developing new applications for it in the future.
YARH.IO is a fully hackable and custamizable Raspberry Pi based handheld, running Raspberry Pi OS and supporting all other Operating Systems available for Raspberry Pi.
Sie finden hier zahlreiche Kartonmodelle zum Ausschneiden und Zusammenkleben, z.B. Burgen, Gebäude und technische Modelle.
Der 1831 gegründete Verlag J.F. Schreiber brachte bereits ab 1878 Kartonmodelle heraus. Seit 1998 wird das Programm der Schreiber-Bogen vom Aue-Verlag in Möckmühl weitergeführt.
Wer seinen PC in eine PDP-11 von DEC mit der UNIX Time-Sharing System Seventh Edition (V7) als Betriebssystem verwandeln möchte, der kann den Sanos-Port von Bob Supnik’s PDP-11 simulator ausprobieren. Denn mit Diesem ist es möglich, UNIX so auszuführen, wie es Dennis Ritchie und Ken Thompson im Jahr 1979 getan haben.
Ein Sanos-Entwickler hat ein ISO-Image mit Sanos, dem PDP-11-Simulator und dem UNIX V7-Kit vom Computer History Simulation Project erstellt. Einfach eine CD-ROM in den PC einlegen und starten. Danach wird für alle nostalgischen UNIX-Geeks der PC zu einer PDP-11 mit dem UNIX V7.
Have you ever wanted a theme tune to play as you enter the room? Perhaps the imperial march, a pop hit or Super Mario’s Jolly Roger Bay. Well now you can thanks to the Human presence triggered music player – a small box which will wait for your arrival and serenade you when you step in trough the door and switch the lights on!
It’s designed for service rooms but has applications for all kinds of locations and establishments. The music is stored on an SD card, which can be selected by pressing the knob – which also controls the volume when turned. You might like to have some relaxing music to accompany a deep bath or something to get you pumped up for the home gym – whatever you choose it’s an unusual and ingenious device. Simply let it play out or turn off the lights to stop the music!
I finally got far enough in my build to show my progress on creating an AGC DSKY as per MIT's original drawings.
