After some discussions here and elsewhere, I've decided to attempt integrating some #PixelBlaze hardware into my project. This will free up 6 DIO pins on the #microcontroller, allowing direct UART connection from the LoRa node.

Plan now is to use a Pixelblaze with their 1 to 8 Output Expander to work out control signaling. Then, produce that signaling from my hardware. The Pixelblaze will be a sort of test jig to use its web UI to write & test.

This way my project can be kept a degree more simple, and I can still trigger various display output depending on different conditions of the bicycle. (One #Neopixel "strip" will be a tail/brake light.)

App Lab for the new UNO Q can be quite limiting. If you want to use the more powerful command line (CLI) to transfer and run projects, check out my guide here:

This one's actually a little old, as it got stuck in the to-publish queue, but still very neat: a 3D-printed isomorphic Hall-effect velocity-sensitive MIDI keyboard powered by an Espressif ESP32. The demo video's worth a watch!

Xavier Dumont's Isomorphic Keyboard Is an Espressif ESP32-Powered Breath-Driven Thing of Wonder

In addition to 48 velocity-sensitive keys, easily expandable, this MIDI gadget can also use your breath as an input.

Maker Chen Liang's published a guide on turning an Espressif ESP32-C5 into a dual-band Wi-Fi analyser - and all you need is a dev board and a display. Well, plus wires and a power source.

Chen Liang Turns Any Espressif ESP32-C5 and a Display Into a Compact Dual-Band Wi-Fi Analyzer

Simple two-component build — plus a battery, if you want it portable — provides real-time monitoring of Wi-Fi congestion.

I guess I will have to find a new platform to expand the effects and control systems of my model trains. Goodbye, Arduino.

Makers slam Qualcomm for tightening the clamps on Arduino

Updated: But the Wiring folks were disenchanted even before Qualcomm swallowed Arduino

Ah, yes, the *"Untold"* 😴 history of a #microcontroller board—because the world was absolutely desperate for a deep dive into nerd drama about who soldered the first wire. ⚡️ Let's pause all technological advancement to squabble over credit where it's due, to rival the excitement of watching paint dry but with more resistors and fewer laughs. 😂

The Untold History of Arduino

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.

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.

I /think/ the string of digits on the front cover does something like:

Set pin2 high
Set pin1 low
nop(?)
Beep once
END

I'm assuming 00=nop, I can't actually find that code in the manual

@lpbkdotnet nop = no operation. It´s widely used as a single cycle processor delay.
Btw. this reminds me on the ATtiny Audio Bootloader by lyok and ChrisMicro for the 8Bit-Mixtape by @dusjagr. Here the Arduino IDE starts to beep for you.

@lpbkdotnet that is wonderfully blursed
@lpbkdotnet this is so cool i love it hah
@lpbkdotnet
That edgy-over-the-top graphic design à la #HackersTheMovie is top notch
@magnetic_tape A friend described it as "aggressively Y2k" and TBH I love it!
@lpbkdotnet
Not only is the universe stranger than we imagine; it is stranger than we _can_ imagine.

@lpbkdotnet

We had a LOT of PIC stuff at Paignton Library for the STEM group, as far as I am aware it is still there, It would be great if anyone in Torbay or surrounding area who would be interest in using it, it could perhaps be obtained for a group at the Library.

Right now it is just gathering dust, I know what it is, no one else does, but I just know it is microcontroller related.

@lpbkdotnet oh wow, clever idea. not, uh, very useful... but clever!
@lpbkdotnet what the fuck
@lpbkdotnet what do i do to have a brain that thinks this is not too strange

@lkundrak I think it's a product that only made sense in the right place, at the right point in history

You need to:
* Be a school in the early 2000s
* Want to teach kids about microcontrollers
* Be a school that doesn't have enough computers to cover that lesson
* Somehow still be OK with students using phones in class?!

I guess it didn't have to be a phone, pocket DTMF keypads were easily available for very little money.

That would certainly be a lot cheaper than buying PCs!

@lpbkdotnet also made for times when we could actually focus
@lpbkdotnet I… don’t know what to say. This is, wow.
@lpbkdotnet so in theory you could phreak a PIC with this
