Creality Sermoon S1 high-end 3D scanner review – Part 1: specifications and unboxing

Creality Sermoon S1 3D scanner review

Creality has sent me the Sermoon S1 high-end 3D scanner for review. It supports blue laser line and infrared structured light scanning, offers high accuracy up to 0.02mm, scans objects from 5 x 5 x 5 m3 to 4000 x 4000 x 4000 mm3, and looks like a pretty cool device overall. I’ll start the review by diving into the specifications, before going through an unboxing to check out the 3D scanner and its accessories. I’ll then need to study a bit more before testing out with different objects in the second part of the review. Sermoon S1 3D scanner specifications Scanning Modes Blue laser lines Single Blue Laser Line Scanning rate: 108,000 measurements/s Working distance – 200 to 600mm Outdoor Scanning – Below 100,000 lux Laser Safety – Class II (eye safe) 7 Parallel Blue Laser Lines Scanning rate: 756,000 measurements/s Working distance – 150 to 400mm Outdoor Scanning […]

kv4p HT – Turn an Android smartphone into a ham radio transceiver

kv4p HT android smartphone ham radio

kv4p HT is an open-source hardware VHF or UHF radio designed to plug into the USB-C port of an Android smartphone and turn it into a handheld ham radio transceiver. It’s based on an ESP32 wireless module and an SA818 radio module. This accessory makes your phone capable of off-grid voice and text communication with a Technician-class amateur radio license. It’s small enough to fit into a pocket, partially because it does not need a battery, relying on the built-in battery of your phone. kv4p HT V2.0 specifications: Wireless module – ESP32-WROOM-32E-N4 SoC – ESP32 dual-core Tensilica LX6 microcontroller @ up to 240 MHz with 520KB SRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth 4.2 BR/LE connectivity, built-in PCB antenna VHF Radio SA818-V radio module or DRA818V (134 – 174MHz) VHF low-pass filter SMA antenna connector Tx Power – Up to 1 Watt for several […]

Home Assistant Connect ZWA-2 Z-Wave USB adapter launched for $69

Home Assistant Connect ZWA-2

Home Assistant Connect ZWA-2 is a new Z-Wave USB adapter with Long Range support, which follows the launch of the Home Assistant Connect ZBT-1 (SkyConnect) Zigbee 3.0, Thread, and Matter USB dongle in 2022. Home Assistant explains that Z-Wave operates in the sub-GHz (865-926 MHz) frequency band, where waves can more easily go through thick walls and reach across large households, and do not need to compete in the crowded 2.4 GHz airspace used by wireless protocols such as Wi-Fi, Bluetooth, Zigbee, and Thread. Home Assistant Connect ZWA-2 specifications: SoCs Silicon Labs ZG23 Cortex-M33 Z-Wave microcontroller @ 78 MHz with ESP32-S3 wireless MCU used as USB-to-serial bridge (WiFi and Bluetooth present, but not used by the firmware) Wireless Z-Wave, Z-Wave Long Range Z-Wave series 800 Range – Tested up to 1.5km (line of sight) by Nabu Casa Antenna Frequency range: 860-930 MHz The frequency used by end devices depends on […]

PANZER-LITE93 Ubuntu 24.04 Box PC puts FRDM-IMX93 development board into a 3D printed case

PANZER-LITE93

MayQueen Technologies PANZER-LITE93 is an NXP i.MX 93-powered box PC running a customized Ubuntu 24.04 LTS distribution with LXQt desktop environment and NPU libraries to leverage the built-in Arm Ethos-U65 micro NPU. The board itself is not actually anything new, and the company has been quite transparent about it, telling us by email that we’d “immediately recognize that it’s based on the FRDM-IMX93” development board. What they bring here is a 3D printed case, software support which we’ve been told is different than official NXP support, and we’ve been told the main goal was to create a lightweight box PC. PANZER-LITE93 specifications: SoC – NXP i.MX 93 CPU Up to 2x Arm Cortex-A55 up to 1.7 GHz 2x Arm Cortex-M33 up to 250 MHz GPU – PXP 2D GPU with blending/composition, resize, color space conversion NPU – Arm Ethos-U65 NPU @ 1 GHz up to 0.5 TOPS Memory – 640 […]

Revopoint Trackit – A high-end optical tracking 3D scanner with marker-free scanning (Sponsored)

Revopoint Trackit optical tracking 3D scanner

Revopoint Trackit is a high-end optical 3D scanner that achieves accurate object tracking for small to large workpieces without needing markers on the object’s surface. This significantly increases scanning efficiency over conventional marker-based 3D scanning systems. The 3D scanner features an optical tracking system ensuring smooth scanning despite complex shapes, angle changes, or position shifts, maintaining stable data acquisition. The scanner offers two scanning modes with a 30-line cross blue laser mode for quick scans and a single-line blue laser mode for capturing narrow, hard-to-reach areas. Both laser modes can deal with dark and shiny surfaces without the need to first apply scanning spray, making it great for capturing delicate workpieces like circuit boards. Other highlights include a wide operating range suitable for small to large pieces (think coins to cars), auto gimbal calibration, and the ability to operate the device as a standalone handheld scanner (with markers). Revopoint Trackit […]

SO-ARM101 robotic arm with hugging face support

SO-ARM101 “Arm Servo Motor Kit” is an open-source dual robotic arm kit that works with Hugging Face’s LeRobot robotics framework and is designed to interface with NVIDIA Jetson AI modules and computers. It is an update to the SO-ARM100 DIY open-source robotic arm kit introduced last year with LeRobot framework support. The new SO-ARM101 is still comprised of leader and follower arms but features improved wiring to prevent disconnection issues previously seen at joint 3, motors with optimized gear ratios, and a few functionality where the leader arm can now follow the follower arm in real-time, which will be used for reinforcement learning (RL) where a human can intervene and correct the robot’s actions. SO-ARM101 specifications: Degrees of Freedom (DOF) – 6 per Arm Motor control Total servo – 12x STS3215 bus servos (6x for each Arm) Leader Arm 1x (7.4V) 1:345 gear ratio motor for No.2 joints 2x (7.4V) […]
