Spaceraccoon ☛ Getting a Shell on the Tapo C260 Camera (CVE-2026-0651, CVE-2026-0652, CVE-2026-0653)
As shared in my previous blogpost, I reverse-engineered the TP-Link Tapo C260 camera for the SPIRITCYBER IoT hardware hacking contest. Despite being one of the latest Tapo camera, I was able to discover some pretty interesting vulnerabilities - local file disclosure (CVE-2026-0651), guest-privilege Remote Code Execution (CVE-2026-0652), and privilege escalation (CVE-2026-0653). The TP-Link advisory covers the basics, but doesn’t include the full discovery process, which is what I’ll focus on here.

[Old] Jesse Anderson ☛ SCD41: On Demand CO2 Sensor
The response time is roughly every 2 minutes for temperature and every 90 seconds for humidity. Using the longest response time as a basis for our sampling, we get a sampling rate of once every 2 minutes. The sensor’s extensive command set, clearly detailed in the datasheet, simplifies programming but requires familiarity with numerous commands.

[Old] eMariete ☛ Sensirion SCD41 and SCD40 CO2 sensors
In this article I bring you an analysis, together with my first impressionsSensirion SCD41 and SCD40 sensors.
Sensirion is a Swedish manufacturer with a long experience in the production of quality CO2 sensors. Its sensor SCD30a dual channel NDIR sensorhas been a benchmark for the last few years. A clear favourite when it came to a quality sensor at an acceptable price.
Recently, during the second quarter of 2021Sensirion has surprised us by adding new members to the CO2 sensor familythe SCD40 and SCD41.

Jeff Geerling ☛ A PTP Wall Clock is impractical and a little too precise
...a repository with rough instructions for the build, and his C++ application to display PTP time (if available on the network) on a set of two LED matrix displays, using a Raspberry Pi.

CNX Software ☛ DFRobot launches low-power, low-cost Fermion: BMV080 air quality sensor module
Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost alternative, the Fermion: BMV080, which provides the same fanless, laboratory-grade PM1, PM2.5, and PM10 sensing capabilities for just $29.90.

CNX Software ☛ WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module
Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, impacting the Arduino Nano RP2040 Connect, Arduino MKR WiFi 1010, and Arduino Nano 33 IoT boards. It’s a long-running problem since the first Arduino board with NINA-W10 was introduced in 2018, and meant you could use WiFi or Bluetooth LE, but not both simultaneously.

CNX Software ☛ Echo Pyramid enables smart voice interaction applications on M5Stack Atom ESP32 IoT controllers
Designed for M5Stack Atom, AtomS3, and AtomS3R series IoT controllers based on ESP32 or ESP32-S3 wireless SoC, the Echo Pyramid base enables smart voice interaction applications such as far-field voice recognition, voice assistants, voice control, and more. The device features a built-in speaker, a MEMS microphone, an ES8311 HD audio codec for playback and capture, and an STM32 MCU for touch areas and RGB LED management.

Interesting Engineering ☛ New 'super foam' absorbs 10× more energy using 3D-printed skeleton
The material combines ordinary foam with 3D-printed plastic columns embedded inside it. These flexible columns, known as struts, form an internal skeleton that reinforces the foam and improves how it handles pressure and impacts.

Hackaday ☛ Portable Tow Rope Batman Would Be Proud Of
The grappling gun was originally designed for a smaller child to get hoisted up a hill on a sled, but when stress testing the device [John] found out that it actually has more than enough capability to haul even an adult up a hill on skis. As an added bonus, the outfeed for the rope can be put into a bag and used to automatically coil the rope up when he’s done at the hill. Although this is a great solution for a portable rope tow, for something more permanent and more powerful take a look at this backyard rope tow that was built from spare parts.

Hackaday ☛ The World’s Smallest Marble Clock With Pick And Place Arm
While he totally loved the massive marble clock that [Ivan Miranda] built, it is a massive contraption that’s hard to justify as a permanent installation. His take on the concept thus makes it as small as possible, by using a pick-and-place style arm to place the marbles instead. Although the marbles don’t do a lot of rolling this way, it’s decidedly more quiet, and replace the rumbling and click-clacking of marbles with the smooth motion of a robotic arm.

Hackaday ☛ How An Old Automatic Stoker Was Hacked Onto A Modern Lancashire Boiler
Hacks are of all ages, with the Victorian-era Claymills Pumping Station being no exception. When its old Lancashire boilers from the 19th century were finally replaced with modern 1930s boilers, the 1920s-era automatic stokers were bodged onto the new boilers with a rather ill-fitting adapter plate, as there was no standard Lancashire boiler design. Nearly a hundred years later it was up to the volunteers at this Victorian-era pumping station to inspect and refurbish this solution, before fitting it back onto the boiler.
