$52 7.5-inch E-paper display connects to ESP32 boards

LILYGO 7-5 inch E-paper Display with T5 ESP32 board

So far LILYGO’s ESP32 boards with an E-Paper display such as the TTGO T5  or Mini E-Paper Core featured smaller displays from 1.02-inch to 2.9-inch. But the company is now offering a larger 7.5-inch display that works with most of its T5 boards excluding the one used with a 4.7-inch display. The black and white e-paper display offers a resolution of 800 x 480 pixels, is Arduino programmable and backward compatible with earlier T5 E-paper solution, and should be one of the most cost-effective to way to make a wireless E-paper display. LilyGO 7.5-inch E-paper display specifications: Panel SKU – DKE DEPG0750_U790F3 (See PDF datasheet. note non-secure link so your browser may complain) Size – 7.5-inch diagonal Resolution – 800 x 480 pixels (124 DPI) Active area – 163.2 x 97.92mm Pixel pitch – 0.204 x 0.204 mm Host interface – SPI Dimensions – 170.2 x 111.2 x 1.2 mm […]

Linux 5.19 Release – Main changes, Arm, RISC-V and MIPS architectures

Linux 5.19 release arm risc-v mips

Linus Torvalds has just announced the release of Linux 5.19. It should be the last 5.xx version, with Linux 6.0 coming for the next cycle: So here we are, one week late, and 5.19 is tagged and pushed out. The full shortlog (just from rc8, obviously not all of 5.19) is below, but I can happily report that there is nothing really interesting in there. A lot of random small stuff. In the diffstat, the loongarch updates stand out, as does another batch of the networking sysctl READ_ONCE() annotations to make some of the data race checker code happy. Other than that it’s really just a mixed bag of various odds and ends. On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, […]

MECOOL KP1 projector review – Part 2: Android 11 TV OS and Full HD clarity

MECOOL KP1 projector review

In the first part of MECOOL KP1 smart projector review, I checked out the package content, projector design, and integrated HDMI stick running Android 11 TV, before going through the setup wizard, and trying the projector with Android 11. I’ve now spent more time with the device, so I’ll report my overall experience. The best way to install the projector is probably to mount it on a ceiling or a wall, but in my case, I just placed it on top of a shelf itself placed on top of a table to adjust the height for a comfortable viewing experience from our comfy seats. As we’ve seen before, the projector will boot directly to the Android 11 TV launcher from the included MECOOL KD5 TV stick. Android 11 TV OS runs on top of Linux 5.4.125, as we can see it’s a Hailstorm device that’s certified for Netflix and an […]

Ortur LU2-10A 10W laser module issues and measuring laser power

Ortur LU2 10A laser module review

Karl here and I will keep this short for you. First I will share my experience installing an upgrade module for the Lasermaster 2 Pro, the Ortur LU2-10A. The LM2Pro came with a 5.5w laser module and this upgrade brings the power up to approximately 10w optical power. Spoiler, I am not happy with the kit. [Update (CNXSoft): The company has put us in direct contact with Ortur engineer, and they’ve promised to help us fix the issue. We’ll update the post if/once it is resolved] The Ortur LU2-10A kit comes with a very simple adapter board that appears to do two tasks. 1 is to adapt wiring, and 2, inject additional power for the higher power laser module. It looks like the board will adapt to a lot of different connection types. I followed the instructions and the first time I plugged everything in the laser came on full […]

Allwinner H618 processor powers Android 12 TV boxes

Allwinner H618 TV Box Android 12

Allwinner H618 processor has started to show up in several TV boxes running Android 12, and capable of playing 6K/4K VP9 and H.265 videos with devices such as T95Z Plus and T95 Max, which may be confusing, as companies are reusing those model numbers over and over. Featuring a quad-core Cortex-A53 processor, an Arm Mali-G31 MP2 GPU, and 6K video support, the Allwinner H618 looks exactly like the Allwinner H616 processor except it can run the more recent Android 12 operating system. There’s not much public information about Allwinner H618 at the time of writing, but let’s check T95Z Plus specifications to see if we can find any other new hidden features: SoC – Allwinner H618 quad-core Arm Cortex-A53 processor @ up to 1.5GHz with Arm Mali-G31 MP2 GPU System Memory – 2GB or 4GB RAM Storage – 16GB, 32GB, or 64GB eMMC flash, MicroSD card socket Video Output HDMI […]

Altium Designer adds 3D PCB layout tool

Altium 3D PCB design

While we like open-source tools such as KiCAD, Altium has added a pretty cool feature to the Altium Designer program with a 3D layout tool, which as its name implies, allows the design of 3D PCBs… The new 3D layout tool relies on 3D-MID technology that combines electrical circuits with three-dimensional mechanical parts. I’m not sure who really needs this, but I have to admit the results look pretty neat. Altium explains the design process is quite similar to standard 2D PCBs, and designers would create a layout on the surface of a 3D substrate using the standard library components and with the connectivity driven by the schematic design in the same way as with a standard PCB. You can check out how it works in a video shared on Altium’s LinkedIn account. The designer would then export the files in the format required by LPKF Laser & Electronics AG’s […]

Pinecil V2 soldering iron gets BL706 Bluetooth LE RISC-V MCU, USB PD EPR support

Pinecil V2 RISC-V soldering iron

PINE64 is about to launch the second generation Pinecil RISC-V soldering iron with the Pinecil V2 featuring a new Bouffalo Lab BL706 RISC-V microcontroller with Bluetooth LE connectivity, optimizations for higher power levels, as well as tentative support for the new USB PD EPR standard (Extended Power Range) working at up to 28V. I don’t solder every day, but when I do, I use my Pinecil soldering iron, as it’s heating super fast and does the job, and in my case, works quite better than the TS100 soldering iron. So it should come as no surprise that the Pincel is the most popular consumer hardware from the PINE64 community (after SOPine modules), and the new Pinecil V2 is a welcome upgrading building on the same design but with Bluetooth LE connectivity and a lower tip resistance. Pinecil V2 preliminary specifications: MCU – Bouffalo Lab BL706 32-bit RISC-V microcontroller @ 144 […]
