Aus Gründen frische ich gerade mein Wissen zu Digitalschaltungen und CMOS auf. Schon vor längerer Zeit habe ich dazu antiquarisch mein Alteisenregal befüllt, u. a. mit "Handbuch TTL- und CMOS-Schaltkreise" von Eberhard Kühn, 3. Auflage 1988. Und als ich darin gestern in einem speziellen Kapitel was nachlesen wollte, stelle ich fest: Da geriet beim Druck bzw. bei der Bindung irgendwas mit den Druckbögen gründlich durcheinander. Eine Reihe Seiten sind doppelt, dafür fehlen viele ande…

⚙️ Print mode runs by default for non-interactive execution, interactive mode enabled via .i. filename marker (task.i.claude .md), _interactive frontmatter key, or -_i CLI flag
🌐 Remote URL imports cached at ~/.mdflow/cache/ with 1-hour TTL, use --no-cache to force fresh fetch, automatic .env file loading from markdown file directory with support for .env.local, .env.development, .env.production

As promised: the design of the CMPTR signal breakout board is released! Does it work? Yep. Is it cheap? Not really. However, it a nice option to have if you have a Sony PVM with a CMPTR connector and you want to use RGBS or RGBI/CGA/TTL.

Ultracompact Wide-FOV Near-infrared Camera with Wafer-level Manufactured Meta-Aspheric Lens
Overcoming the trade-off between wide field of view (FOV) and compactness remains a central challenge for integrating near-infrared (NIR) imaging into smartphones and AR glasses. Existing refractive NIR optics cannot simultaneously achieve ultra-wide angles above 100° and ultrathin total track length (TTL) below 5 mm, limiting their use in portable devices. Here, we present a wafer-level-manufactured meta-aspheric lens (MAL) that achieves a 101.5° FOV, 3.39 mm TTL, and F/1.64 aperture within …
