TwoTrees SK1 review – A CoreXY 3D printer with high printing speeds

Two Trees SK1 3D Printer Review

TwoTrees SK1 is an FDM 3D printer with a working area of 256 x 256 x 256 mm and a CoreXY system that can print 3 to 5 times faster than a typical 3D printer. The movements of a CoreXY 3D printer are achieved by moving two motors simultaneously. The TwoTrees SK1 CoreXY 3D printer can print at a maximum speed of 700 mm/s and features automatic Z-Tilt base leveling with a 36-point mesh bed. The print head uses a dual-gear direct extruder to feed the filament directly to the nozzle and the nozzle supports up to 300 degrees Celsius. The printer also comes preloaded with the popular Klipper firmware. TwoTrees SK1 specifications Printing size – 256 x 256 x 256 mm Dimensions – 400 x 400 x 530 mm Printing speed – Up to 700mm/s Acceleration – Up to 20,000 mm/s2 Nozzle temperature – Up to 300ºC Guide rail […]

Beelink SEi12 i7-12650H mini PC review – Part 3: Ubuntu 22.04 Linux

Beelink SEi12 i7-12650H mini PC Review Ubuntu 22.04

After going through an unboxing and teardown of the Beelink SEi12 i7-12650H mini PC, and testing the 12th gen Intel Core i7-12650H mini PC in Windows 11 Pro, we’ll now report our experience with Ubuntu 22.04 in the third part of the review to show how the Beelink SEi12 performs in Linux. We will perform feature testing, run some benchmarks to evaluate performance, test Ethernet, WiFi 6, and Bluetooth, submit the system to a stress test to check its cooling performance and measure fan noise and power consumption. We’ll also compare it to the GEEKOM Mini IT12 mini PC with the same Intel Core i7-12650H CPU. Ubuntu 22.04 installation We shrank the Windows partition is about half to install Ubuntu 22.04 in dual boot configuration along with Windows 11 Pro. We then installed Ubuntu 22.04.3 ISO from a USB flash without any issues. Ubuntu 22.04 system information After a system […]

Scaleway launches hosted RISC-V servers for 15.99 Euros per month

Scaleaway Elastic Metal RISC-V servers

French company Scaleway has just launched the “Elastic Metal RV1” bare metal servers which it claims to be the world’s first RISC-V servers available in the cloud with pricing at 0.042 Euros per hour, or 15.99 Euros a month excluding VAT. Scaleway launched some Arm servers based on Marvell Armada 370/XP quad-core Cortex A9 processor in 2015 before phasing those out a few years ago, and they are now just offering AMD and Intel-based servers and hosted Apple Mac computers based on the M1 Arm chip. But the company has decided to try something new again with the EM-RV1 servers based on Alibaba T-Head TH1520 quad-core RISC-V processor, 16GB RAM, and 128GB eMMC flash and running Debian, Ubuntu, or Alpine. EM-RV1-C4M16S128-A instance key features and specifications: SoC – Alibaba T-Head TH1520 CPU – Quad-core RISC-V Xuantie C910 (RV64GCV) processor @ 1.85 GHz GPU – Imagination BXM-4-64 with support for OpenCL […]

Embedded Open Source Summit 2024 schedule – Embedded Linux, Zephyr OS, and Real-time Linux

Embedded Open Source Summit 2024

The Embedded Open Source Summit 2024 (EOSS 2024) will take place on April 16-18 and the Linux Foundation has already announced the schedule with conference sessions, lightning talks, and birds of a feather (BoF) sessions covering embedded Linux, Zephyr OS, and real-time (RT) Linux. While I won’t be attending in person, I still find it interesting to check out the schedule as we may learn more about the current status of embedded Linux. So I’ve created my own little virtual schedule out of the available talks. Tuesday, April 16 – Day 1, Embedded Open Source Summit 2024 9:05 – 9:45 – No, It’s (Still) Never Too Late to Upstream Your Legacy Linux-Based Platforms by Neil Armstrong, Linaro Nearly 7 years ago, Neil already spoke about this subject in Berlin, and it’s still very true. Do you maintain or used to maintain a Linux-based board or SoC off-tree? Then there are […]

CTL Chromebook NL73 Series to support 5G RedCap with a Snapdragon X35 modem

Chromebook 5G RedCap

CTL Chromebook NL73 Series based on Intel Processor N100 or N200 SoC will be offered with a Snapdragon X35 modem to support the new 5G RedCap (Reduced Capability) standard. 5G RedCap – also known as 5G NR-Light – keeps some 5G features such as low latency, low power consumption, enhanced security, and network slicing while limiting the bandwidth to around a few hundred Mbps. It was initially designed to target industrial IoT applications, but Qualcomm also mentioned its Snapdragon X35 modem could be used in smartwatches and XR glasses when it was first announced, and it might be used in other cost-sensitive devices such as Chromebooks.
