Woot, just finished implementing my first GitHub / Forgejo Actions which allows me to programmatically push meshcore builds to my radios on the roof from the comfort of my browser.

It currently only supports deploying to esp32s3 based LoRa devices so far.

Celle-ci, il y a bien des fans de Arduino, des fans d'électronique, des nerds enfermés dans leur fablab qui seraient trop chaud·es de me la fabriquer ça nan ?

Questions, 4 of 3 (Told ya!)

I want to use a piezo knock sensor so I can tap on the glass and turn the lights on without breaking the door seal. Can I mount the piezo anywhere in the cabinet, or does it need to be on the door.

There are 14 millions piezo sensor tutorials on the web, but every one of them starts with "What's an Arduino?" and and ends with the piezo plugged into a breadboard. Nobody explains the mechanical considerations.

Questions, 3 of 3 (for now).

I want to drive an LCD panel (not pictured). The one I bought uses SPI. If I want to run animations, it needs ~40 MHz. Is it possible to run SPI at that speed through a one meter wire, or should I put another MCU on the back of the display and run USB to it?

I'm leaning toward another MCU.

Thanks.

Questions, 2 of 3.

What's the best way to attach a wire to a LED strip? When I just solder them on, they eventually break off. Could I make a small PCB and bond the strip to that? Should I print some kind of clamp/strain relief thing to hold the wire end in place? If I do the PCB, I'll throw some capacitance on.

I have about 2 cm between the end of the strip and the end of the channel.

Thanks.

Questions, 1 of 3.

I'm planning to wire the six LED channels in parallel, driven from six GPIOs.

I am looking for a good way to connect the wires to the controller board in back. For other recent projects I used JST SL, but I don't want to use them again. They're too big, too hard to unlatch, and not wire-to-board. Maybe Molex CLIK-Mate? Other suggestions? I don't want to buy a crimping tool...

Each LED strip will use 2.25 amps max.

Thanks.

@3dprinting Here are my current thoughts about the Filabilly Humidor's wiring harness. Description in the alt text.

I have questions; see the next few posts.
