These days, everyone’s got a million different devices that can take a passable photo. That’s not special anymore. A camera that draws what it sees, though? That’s kind of fun. That’s precisely what [Jens] has built—an instant sketch camera!

The sketch camera looks like a miniature drawing easel, holding a rectangular slip of paper not dissimilar in size to the Polaroid film of old. The 3D-printed frame rocks a Raspberry Pi controlling a simple pen plotter, using SG90 servos to position the drawing implement and trace out a drawing. So far, so simple. The real magic is in the image processing, which takes any old photo with the Pi camera and turns it into a sketch in the first place. This is achieved with the OpenCV image processing library, using an edge detection algorithm along with some additional filtering to do the job.

If you’ve ever wanted to take Polaroids that looked like sketches when you’re out on the go, this is a great way to do it. We’ve featured some other great plotter builds before, too, just few that are as compact and portable as this one. Video after the break.

Gli specialisti di Group-IB hanno registrato nuovi attacchi da parte del gruppo hacker Bloody Wolf, che ha preso di mira il Kirghizistan da giugno 2025 e ha esteso le sue attività all’Uzbekistan da ottobre. Il settore finanziario, le agenzie governative e le aziende IT sono a rischio.

Secondo i ricercatori, gli aggressori si spacciano per il Ministero della Giustizia del Kirghizistan, utilizzando documenti PDF falsi e domini che sembrano legittimi, ma che in realtà distribuiscono archivi Java (JAR) contenenti il malware NetSupport RAT.

Bloody Wolf è attivo almeno dalla fine del 2023. In precedenza, il gruppo aveva attaccato il Kazakistan e la Russia, distribuendo STRRAT e NetSupport tramite phishing. Ora, la portata geografica del gruppo si è estesa all’Asia centrale, ma le tattiche rimangono le stesse: nelle e-mail, il gruppo si spaccia per funzionari governativi, cercando di indurre le vittime ad aprire allegati dannosi.

Lo schema di attacco è semplice. La vittima riceve un’e-mail contenente un collegamento a un documento apparentemente importante. Cliccando sul collegamento, viene scaricato un file JAR insieme alle istruzioni per l’installazione di Java Runtime. L’e-mail afferma che Java è necessario per visualizzare i file, ma in realtà il downloader scarica NetSupport RAT dal server degli hacker e si installa sul sistema in tre modi: tramite un’attività pianificata, una voce di registro nel registro di Windows e un file BAT nella cartella di avvio.

Gli esperti scrivono che durante gli attacchi alle organizzazioni uzbeke, gli hacker hanno utilizzato il geofencing: se una richiesta proveniva dall’esterno dell’Uzbekistan, la vittima veniva reindirizzata al sito web legittimo data.egov.uz. Tuttavia, le richieste provenienti dall’interno del Paese attivavano il download di un file JAR da un link incorporato in un PDF.

Si noti che tutti i downloader JAR del gruppo sono compilati utilizzando una versione precedente di Java 8 (rilasciata a marzo 2014). Gli esperti ritengono che il gruppo disponga di un proprio generatore o modello per la creazione di tali file. Inoltre, anche la versione del malware NetSupport è tutt’altro che recente, risalendo a ottobre 2013.

I ricercatori concludono che Bloody Wolf dimostra che anche strumenti commerciali economici possono trasformarsi in armi efficaci per attacchi mirati e sofisticati.

Surgery is hard, there is a reason why school is so long for the profession. Making the job easier and smoother for both patients and surgeons is valuable for all parties, which is why [Mayo Clinic] is now working on including 3D printing into its more regular medicine pipeline.

Prepping for surgery often requires examining CT scans of patients to figure out, well, what they’re even going to be doing. Every body is different, and complex surgical procedures require checking to see where certain organs or features are located. This can be made much easier with a physical model of where the bones, organs, or nerves are specifically located in a patient. While this isn’t true in every case of treatment, there are even cancerous cases where custom equipment can be used to decrease side effects, such as mini-beam collimator adapters.

What if you could use the same pipeline to print what was lost from certain procedures? In a mastectomy, the breast tissue is removed, which can cause negative attention from curious gazes. So why not 3D print a custom breast? Cases like these are generally considered poor commercial investments from industry, but are relatively easy for an existing medical facility to add to treatment.

[Mayo Clinic] is far from the first to consider 3D printing in the medical setting, but seeing the technology see actual applied use rather than future seeking is exciting. Medical hacking is always exciting, and if you want to see more examples, keep sure to check out this commercially available simulator (with some free models).

If you want to know when the train is coming, you could pull up a webpage on your phone, or walk all the way to the station to look at the displays there. Or, like [eastfamilyreddish], you could build a neat little train info display to decorate your desktop instead.

The build is based on the work of [gadec-uk]—who developed a train information display some time ago. It’s based around an ESP32 D1 Mini, paired with a 256 x 64 OLED screen to display relevant train information. It accesses a National Rail API for train status information—known as the Darwin LDBWS (Live Departure Board Webservice). Configuration is via a web GUI hosted by the ESP32 itself.

[eastfamilyreddish] took the concept further by adapting this hardware into a more pleasing form. The ESP32 and OLED screen are built into a neat little hanging sign setup that apes one you might expect to see at a real railway station. You might expect that 3D printing was involved, but instead, this was achieved with lasercut parts and resin casting to create something with a beautiful finish. They even went so far as to include a wireless phone charging module in the base, making the device extra useful to really earn its place on the desktop.

The fact is, around these parts we love both trains and the displays you find around them. If you’ve got a railway-adjacent project, or you’ve just built your own awesome railway, don’t hesitate to let us know on the tipsline!

Sometimes you need to know what temperature something is, but you don’t quite want to touch it. At times like these, you might want a temp gun on hand to get a good reading, like the one [Arnov Sharma] built.

The build is a relatively simple one, and is based around an Waveshare ESP32 C6 development module that comes with a small LCD screen out of the box. The microcontroller is set up to read an MLX90614 infrared temperature sensor. This device picks up the infrared energy that is emitted by objects relative to their temperature. The sensor has a great range—from -70 C to 380 C. The readouts from this sensor are then displayed on the screen. Battery power is from a small 600 mAh LiPo cell, which is managed by a IP5306 charge module.

It’s worth noting that these infrared temperature sensors aren’t infallible devices. The temperature they perceive is based on certain assumptions about factors like an objects emissivity. Thus, they don’t always give accurate readings on metallic or shiny objects, for example. It’s also important to understand the sensor’s field of view. Despite many commercial versions featuring a laser pointer for aiming, many of these infrared temperature sensors tend to average their reading over a small spot that gets larger the farther away they are from the object being measured.

Tools like portable temp guns are pretty cheap, but sometimes it’s just fun to build your own. Plus, you usually learn something along the way. Video after the break.
