Electronic tinkerers, hobbyists, jack of all trades;

A question for you; How do you plan out your #microcontroller projects, especially when it comes to layout/housing, etc.

For example; I have an #ESP32 project that is going to require a handful of seperate, but connected #modules / #boards (e.g. antenna/extension, usb, solar, bms, etc.) and conceptually it'd be nice to plan these things out rather than just throw them all at a housing and hot glue it all in place 🤣

Does such a tool exist? I could see it being problematic with 400 different bms/solar/charging modules all in different footprints, but figured I'd toss out the question to the verse and see if anyone had feedback.

Thanks!

If you’ve written a Windows application that can read the Serial Number/Unique ID, or even the Vendor ID or Product ID of a microcontroller board (Pi Pico in my case) I’d appreciate any pointers.

Libmpix on Zephyr OS is an open source pipeline for image processing. #simd and #micropython support are in progress.

Today in "weird stuff I forgot I owned"

The PhonePIC is a PIC programmer from the early 2000s, that allows you to program a microcontroller by sending it DTMF tones.

The board has a mic attached to it, that you hold up to you phones handset and then press keys to write programs!

I'm not sure if this makes PIC programming easier, or harder.

So I spent some time optimizing the #MeshCore firmware to use less power on some companion devices.

Especially if you are using devices based on #nrf52840 like #T1000E or #WisMeshTag and want to avoid draining the battery when the device is powered off, you might want to look at https://github.com/meshcore-dev/MeshCore/pull/1122.

Tests and feedback welcome!

Wiring Christmas lights in series may not be the brightest idea, but wiring a sensor in series with a resistor is the fundamental microcontroller input pull-up (or pull-down) circuit.
