[Poking Technology] doesn’t think much of his new smartwatch. It is, by his admission, the cheapest possible smartwatch, coming in at about $3. It has very few useful features but he has figured out how to port MicroPython to it, so for a wrist-mounted development board with BLE, it might be useful. You can check it out in the video below.

The first step is a teardown, which reveals surprisingly little on the inside. There’s a tiny battery, a few connections, a display, and a tiny CPU board. There are, luckily, a few test pads that let you get into the CPU. What do you get? A 24 MHz Telink CPU with 512k of flash and 16k of RAM, along with all the other hardware.

Of course, even if you just want a display with some smarts, $3 might be in your price range. The whole thing wound up taped down to a PCB. But the usual debugger didn’t want to connect. Grabbing an oscilloscope revealed that the output from the board had some level problems. He eventually wrote his own debugger interface using a Pi Pico.

He was able to find the onboard CPU’s development tools. The CPU claims to be proprietary but looks suspiciously like a slightly modified ARM. A short investigation shows that the object code is extremely similar to the ARM Thumb instruction set but with a few extra bits set and different mnemonics. But once you put Python on board, who really cares?

The only downside is that it doesn’t appear that the BLE is practically usable because of memory limitations. But there are still places you might use the little watch in a project.

If you want a smartwatch, maybe build your own. While many DIY watches are simple, you can get pretty complicated if you like.

Doubts on the European Commission's claim of an investment gap of at least €174 billion to meet Europe's 2030 connectivity targets have been shed in a document shared with Euractiv by lobby association CCIA Europe, representing Amazon, Google and Meta, among others.

It’s a great joke, and like all great jokes it makes you think. [Søren Fuglede Jørgensen] managed to cram a 15 M parameter large language model into a completely valid TrueType font: llama.ttf. Being an LLM-in-a-font means that it’ll do its magic across applications – in your photo editor as well as in your text editor.

What magic, we hear you ask? Say you have some text, written in some non-AI-enabled font. Highlight that, and swap over to llama.ttf. The first thing it does is to change all “o” characters to “ø”s, just like [Søren]’s parents did with his name. But the real magic comes when you type a length of exclamation points. In any normal font, they’re just exclamation points, but llama.ttf replaces them with the output of the TinyStories LLM, run locally in the font. Switching back to another font reveals them to be exclamation points after all. Bønkers!

This is all made possible by the HarfBuzz font extensions library. In the name of making custom ligatures and other text shaping possible, HarfBuzz allows fonts to contain Web Assembly code and runs it in a virtual machine at rendering time. This gives font designers the flexibility to render various Unicode combinations as unique glyphs, which is useful for languages like Persian. But it can just as well turn all “o”s into “ø”s or run all exclamation points through an LLM.

Something screams mischief about running arbitrary WASM while you type, but we remind you that since PostScript, font rendering engines have been able to run code in order to help with the formatting problem. This ability was inherited by PDF, and has kept malicious PDFs in the top-10 infiltration vectors for the last fifteen years. [Citation needed.] So if you can model a CPU in PDF, why not an LLM in TTF? Or a Pokemon clone in an OpenType font?

We don’t think [Søren] was making a security point here, we think he was just having fun. You can see how much fun in his video demo embedded below.

This week Jonathan Bennett and Doc Searls chat with Igor Pecovnik and Ricardo Pardini about Armbian, the Debian-based distro tailor made for single-board computers. There’s more than just Raspberry Pi to talk about, with the crew griping about ancient vendor kernels, the less-than-easy ARM boot process, and more!

Meshtastic is a way to build mesh networks using LoRa that is independent of cell towers, hot spots or traditional repeaters. It stands to reason that with an SDR and GNU Radio, you could send and receive Meshtastic messages. That’s exactly what [Josh Conway] built, and you can see a video about the project, Meshtastic_SDR, below. The video is from [cemaxecuter], who puts the library through its paces.

For hardware, the video uses a Canary I as well as the WarDragon software-defined radio kit which is an Airspy R2 and a mini PC running Dragon OS — a Linux distribution aimed at SDR work — in a rugged case. GNU Radio, of course, uses flows which are really just Python modules strung together with a GUI.

The GNU blocks send and receive data via TCP port, so using the radio as a data connection is simple enough. The flow graph itself for the receiver looks daunting, but we have a feeling you won’t change the default very much.

If you’ve wanted to dip your toe into Meshtastic or you want a meaty example of using GNU Radio, this would be a fun project to duplicate and extend. While Meshtastic is generally a mesh protocol, you can set up a node to act as a repeater. You never know when decentralized communications might save the day.

@Notizie dall'Italia e dal mondo

Unione Europea, una Agenzia delle Nazioni Unite ed un Programma ONU insieme per contrastare il traffico di rifiuti, in un progetto a medio termine denominato #UNWASTE.
Di cosa si tratta?
Il commercio illegale di rifiuti (o traffico di rifiuti) è un reato che colpisce l’ambiente ed è un problema crescente in tutto il mondo. Una volta raggiunti i paesi di destinazione, i rifiuti illegali spesso finiscono in discariche illegali e siti di stoccaggio illegali o vengono bruciati all’aperto, causando danni all’ambiente e alla salute umana, minando il raggiungimento degli Obiettivi di Sviluppo Sostenibile e la transizione verso un’economia circolare.

I flussi illegali di rifiuti sono spesso nascosti dietro movimenti transfrontalieri controllati o legali. I confini tra le attività lecite e quelle illecite nel traffico di rifiuti possono essere sottili e le attività, gli attori e il modus operandi coinvolti spesso si sovrappongono e si alimentano a vicenda.

La mappatura dei flussi di rifiuti, una migliore conoscenza del modus operandi delle reti di traffico di rifiuti nonché la cooperazione nazionale, regionale e interregionale sono essenziali per affrontare il traffico di rifiuti.

Paesi del Sud-Est asiatico
Dal 2018, i paesi del sud-est asiatico, tra cui Indonesia, Malesia, Tailandia e Vietnam, sono diventati le principali destinazioni regionali per l’afflusso di rifiuti legali e illegali. Nonostante i quadri giuridici nazionali e internazionali esistenti, l’esistenza di divieti sul commercio di rifiuti e le restrizioni messe in atto dai governi regionali negli ultimi anni, i rifiuti problematici continuano a raggiungere questi paesi.

Il progetto Unwaste
Mira a combattere il traffico di rifiuti tra l’ #UE e il Sud-Est asiatico promuovendo partenariati rafforzati tra gli Stati membri UE-ASEAN (organizzazione politica, economica e culturale di nazioni situate nel sud-est asiatico, a cui è collegata l'omonima area di libero scambio), a sostegno degli sforzi in corso verso una transizione all’economia circolare, in linea con i quadri politici pertinenti.

Gli obiettivi del progetto sono:

- Comprendere meglio i flussi di rifiuti tra l’Europa e il Sud-Est asiatico, con un’ulteriore attenzione all’impatto della pandemia di COVID-19 sui movimenti di rifiuti sanitari e pericolosi.
- Promuovere la cooperazione attraverso dialoghi nazionali per combattere i movimenti illeciti di rifiuti dall’UE verso il sud-est asiatico.
- Facilitare i dialoghi intra e interregionali a livello politico per promuovere il partenariato tra l’UE e i paesi del sud-est asiatico, a sostegno dell’approccio dell’economia circolare.

Questo progetto è realizzato in collaborazione con il Programma delle Nazioni Unite per l'ambiente (#UNEP) e finanziato dall'Unione Europea, impegnata sul campo anche con il proprio #OLAF, l'Ufficio Europeo per la lotta anti-frode. Per altro il 20 maggio scorso è entrata in vigore una nuova normativa europea sul trasporto transfrontaliero di rifiuti: prevede regole più severe sulle esportazioni di rifiuti al di fuori dell'Unione Europea e mira a favorire il riciclaggio all'interno degli Stati membri. Si stima che un terzo delle spedizioni internazionali di rifiuti sia illegale. Il filmato che segue dimostra l'attività svolta da OLAF congiuntamente all' Agenzia delle Dogane in Genova, ed reperibile a questo link:
