Finally! A Home Upgrade That Makes Sense (E-Ink Display) – YouTube
Posted by jpluimers on 2026/06/17
Interesting, especially for my mentally retarded brother, as it uses a large E-ink display.
For him, it would require some batteries as well.
I learned from this that HomeAssistant has goodl Google integration. Great!

The manufacturer of 18650 lithium-ion battery cells matters a lot: The Lumafield Battery Quality Report
Posted by jpluimers on 2026/06/09
A very important report from September 2025 for users of 18650 lithium-ion battery cells: [Wayback/Archive] The Lumafield Battery Quality Report.
Summary:
… beneath the surface, a hidden world of quality control issues and dangerous counterfeits puts consumers and manufacturers at risk.
…
Our automated analysis focused on key indicators of cell safety and quality, including anode overhang (AOH) and edge alignment, two critical factors that directly impact battery performance and safety.
…
Flawed anq quality battery cells:

Osmo-fl2k – osmo-fl2k – Open Source Mobile Communications
Posted by jpluimers on 2026/06/03
Interesting, but be aware that using it outside a shielded environment likekly is illegal: [Wayback/Archive] Osmo-fl2k – osmo-fl2k – Open Source Mobile Communications
- osmo-fl2k allows to use USB 3.0 to VGA adapters based on the Fresco Logic FL2000 chip, which are available for around $5, as general purpose DACs and SDR transmitter generating a continuous stream of samples by avoiding the HSYNC and VSYNC blanking intervals.
…
- Operating a transmitter with the unfiltered FL2000 DAC output attached to an antenna outside a RF shielding chamber is dangerous. Don’t do it!

I Built a Commodore 64 Laptop That Never Existed (PI + EMULATION) – The Portable 64 Concept Design – YouTube
Posted by jpluimers on 2026/05/06
Cool to see what 3D printing plus a Raspberry Pi emulating a C64 can do [Wayback/Archive] I Built a Commodore 64 Laptop That Never Existed (PI + EMULATION) – The Portable 64 Concept Design – YouTube.
The Portable 64 with an original Commodore 64 joystick
However, published in December 2025 after Commodore had been resurrected from the C= brands, it would have been way cooler if was based on new Commodore 64 Ultimate hardware.
Maybe someone will do such a portable computer based on that hardware, or even better that it becomes available at [Wayback/Archive] Home | Commodore.
