New toy to replace my aging mi band 6 which only holds a charge for 2 days

No idea how you typical smart watch users do it drives me batshit crazy to charge more than once a week another thing

La storia di oggi è talmente assurda che viola le leggi della #fisica… cioè, è di ieri, ma ho aspettato un po’ perché speravo il #problema si risolvesse da solo. Assolutamente non è stato ciò il caso. 😩️

Chi si ricorda dei braccialetti nuovi che avevo preso per la Mi Band? Ieri, nel momento in cui dovevo farmi la doccia, mi seccavo di togliere dal polso, quindi ho tenuto, e ho così scoperto che sono comunque leggermente idrofobici; nonostante il materiale in tessuto, si asciugano all’aria da soli relativamente subito… non male. 😳️

Tuttavia, c’è un problemino. Per la prima volta nella sua vita, questo affare cinese ha subito infiltrazioni d’acqua. È trasuta l’acqua dentro, tra lo schermo e la copertura esterna di plastica, e quindi ora io mi devo tenere la Mi Band in queste condizioni#mannaggia allo zio perone! 😭️😭️😭️

Con una luce puntata bene sopra, è evidentissima la collezione di goccioline stronze che si è formata; tra l’altro, con un pattern strano, più grande verso la cima del display e che termina sul centro (sembra complessivamente una goccia storta, ironicamente). Quando la luce non è forte, comunque si vede il display leggermente più sfocato del normale, e due o tre goccioline più grandi sparse sopra in base all’angolazione. 😶‍🌫️️

Io non ho idea di come sia successo, mi sento scammata, è tutto così orribile. È #condensa? La Mi Band, lo dico per esperienza, sopporta tranquillamente l’immersione in #acqua (a profondità non esagerate); viene da sé che dovrebbe reggere benissimo in #doccia (come ha fatto in passato). In condizioni acquatiche ben peggiori non gli è mai successo niente, invece stavolta toh, la macchia. 💩️

Nemmeno pensavo ci fosse spazio lì in mezzo, ma evidentemente… anche perché, premendo col dito sulla plastica di fronte, si sente che si piega leggermente in dentro. E non riesco a immaginare da dove siano entrate queste #gocce! Ho ispezionato a fondo la scocca della #band (che non è mai stata smontata), ma non vedo buchi o fessure. 😾️

Pessimo design destinato a fallire prima o poi, o #complotto ai miei danni come sempre? Non lo sapremo mai, ma io i miei sospetti li ho. Questa è la Band 3, che comprai quando era nuova, quindi siamo ormai 3 o 4 anni al di fuori del periodo di garanzia… capitano letteralmente tutte a me. 🗡️

Al di là di tutto, questa non è una scusa per comprare una nuova Mi Band, come invece la mia parte malvagia vorrebbe… Da un lato, era inconcepibile fallisse in questo modo, eppure lo ha appena fatto, quindi difficile fidarsi del brand ora; dall’altro, questa al momento funziona ancora, per fortuna… 🎐️

Cioè, in realtà, tra ieri e stamattina mi ha dato di frequente problemi con il non registrare i tocchi (cosa che dopo l’acqua mi ha già fatto altre volte, più temporaneamente), ma ora sembra andare… speriamo. Cineserie odio consumismo detesto!!! Se si spacc torno al Casio per sempre. 👿️

Hackaday Links: March 6, 2022

As if the war in Ukraine weren't bad enough right here on Earth, it threatens knock-on effects that could be felt as far away as Mars. One victim of the deteriorating relationships between nations is the next phase of the ExoMars project, a joint ESA-Roscosmos mission that includes the Rosalind Franklin rover. The long-delayed mission was most recently set for launch in October 2022, but the ESA says that hitting the narrow launch window is now "very unlikely." That's a shame, since the orbital dynamics of Earth and Mars will mean that it'll be 2024 before another Hohmann Transfer window opens. There are also going to be repercussions throughout the launch industry due to Russia pulling the Soyuz launch team out of the ESA's spaceport in Guiana. And things have to be mighty tense aboard the ISS right about now, since the station requires periodic orbital boosting with Russian Progress rockets.

If you wear a fitness band, chances are pretty good you do so for health reasons. The idea of keeping track of your activity and vitals around the clock makes sense -- right up until your wrist bursts into flames. At least that's what's reported to have happened to 174 Fitbit smartwatch users, resulting in a recall of 1.7 million units. The problem, unsurprisingly, is the lithium battery, overheating of which has resulted in 78 reported cases of burns. Injuries from overheating seem to be pretty rare, but Googling around for some images of injuries is pretty risky for the weak-stomached. You've been warned.

If you're into embedded design and RT-Thread, you might want to take a look at the contest LCSC and other companies are sponsoring. The challenge is to come up with a design that uses the CH32V307, a 32-bit RISC-V microcontroller. Whatever you come up with needs to use RT-Thread as an OS. If you've got an embedded idea that you're itching to try, this might be a good contest to try. Accepted entries all get either a CH32V307 dev board or chip, and you have until April 30 to get your entry in.

Here's one from the "Malicious Compliance" files, with just a touch of social engineering. It's the story of the most ridiculous railway ever built, and how it's used to skirt around protectionist trade laws. The Bayside Canadian Railway is all of 200 feet (61 meters) long, and goes exactly nowhere other than from one side of a parking lot to the other in the province of New Brunswick. It has a small locomotive and exactly one flatbed car. Frozen fish from Alaska are shipped through the Panama Canal to a port in New Brunswick, loaded onto semi-trucks, and then are driven onto the flatbed rail car.

After their 45-second trip down the track, they're driven back off the railway and across the border into Maine, thereby completing part of their journey to market on a railroad in Canada. This allows the load to qualify for an exemption to the USA's 1920 Jones Act, which prevents foreign vessels from moving cargo between American ports. Figuring out exactly how all this makes financial sense is left as an exercise for the reader, but we suspect that it will boil down to something like, "Technically legal is the best kind of legal."

Reverse Engineering A Very Cheap Fitness Band

With the rise of big-name smartwatches in the marketplace, there are also a smattering of lower-end offerings. The M6 fitness band is one of them, and [Raphael] set about hacking the cheap device with a custom firmware of his own creation.

The M6 band, which sells for around $6, appears to trade on name similarity to the more expensive (~$50) Xiaomi Mi Smart Band 6 fitness tracker. Upon disassembly, [Raphael] found that the system-on-chip running the show is a Telink TLSR8232. It's paired with a 160×80 display, a small LiPo battery for power, and a vibration motor and what appears to be a fake heart rate sensor.

[Raphael] wanted to flash the SOC with a new firmware, and learned a lot from code for a similar part created by [atc1441]. It took some time to figure out how to program the chip using the somewhat oddball SWire interface, but [Raphael] persevered and eventually got things going after much research and experimentation.

From there, it was yet further work to figure out how to read the capacitive button input as well as how to drive the screen, but [Raphael] succeeded in the end. The final result was whipping up a firmware that allowed him to read Bluetooth Low Energy soil moisture sensors he has installed in his plants at home.

It's not [Raphael], aka [rbaron]'s first bite at the cherry; we've featured his efforts in hacking similar fitness bands before! Video after the break.

To draw text, I borrowed the Picopixel bitmap font and wrote a little text rendering function. All so we could enjoy this cinematic masterpiece. pic.twitter.com/0KqR0RPPt7
