Populating a PCB I designed for a customers amp. The original fiberboard was conductive and poorly made, so proper FR4 was done.

多分カーボンプレートよりFR4プレートのほうがより好みの音になるんだよな～～～
純正交換パーツが売ってればいいのに

oooh that would indeed look cool! Brightest timeline I could find someone local or local-ish to me to make the panels, though the FR4 panels are decidedly not local right now. Our foray into guitar pedals means there's an even bigger need for me to figure it out.

PCB antennas are really hard to get right. Luckily FR4 makes excellent coasters.

Don’t Give Up
A mixed media artwork (needle felted wool, acrylic, gouache, handmade kozo, copper clad FR4 panel, artists urine) on a 9x12 inch piece of upholstery foam. A quilt-like pattern of needle felted squares frame a paper wrapped copper panel. Arms and a head with a round snout and long floppy ears emerge from the quilt to hug the panel. The panel has a drawing of a sad creature uncomfortably curled up tightly in the panel too small for its own size. The creature looks up at the quilt that is embracing it. Made for Anthros

ça me fait marrer, la tv qui se plaint de netflix... mais ce soir en prime il y a 10 chaines qui rediffuse un programme sur 21 chaînes... et pas que les petites chaines: Fr3, Fr4 et M6.
tu m'étonnes que plus personne ne regarde la TV

Inhibiting glycolysis is sufficient to diminish autoreactive CD4 T-cell responses and may be therapeutically applicable to other T cell–mediated inflammatory diseases.

Read here ➡️ doi.org/10.2337/db25-1152
The image illustrates the impact of metabolic blockade of glycolysis on autoimmune CD4 T-cell effector responses in Type 1 diabetes. It compares two scenarios: polyclonal CD4 T cells and autoreactive CD4 T cells. Both feature antigen-presenting cells (APCs) and CD4 T cells with receptors and molecules depicted, such as CD80/86, glucose, 2-DG, CD73, FR4, and TCR. The left shows basal glycolysis, while the right highlights reduced IFNγ.

FR4 is the circuit-board material, so it flexes and sounds neutral.
Aluminium feels firmer and rings until you pack in foam.
Add foam and the feel gap between plates mostly vanishes.

An aluminium keyboard plate rings bright and firm; FR4 flexes soft and stays neutral. Same switches, completely different voice. The plate shapes your typing more than the switch does.
