Wainlux K6 & Alfawise C50 Mini Laser Engravers Offered for $130 and Up

A few days ago I saw Wainlux K6 “most compact, powerful and simple-to-use” laser engraver on Kickstarter for about $159. I did not think too much of it at the time, but this morning I thought it already showed up for pre-order on GearBest for $129.99 as Alfawise C50. But I was mistaken, as both products are different, albeit sharing some of the same attributes. Nevertheless, this brought back my curiosity about these types of devices, especially with Wainlux K6 having already managed to raise over $200,000 from close to 1,400 backers so far. So let’s look at both. Wainlux K6 Laser Engraver Key features and specifications: Laser Source – OSRAM Semiconductor blue color laser Laser Power – Up to 3,000 mW, 100 adjustable levels of power Engraving area – 8 x 8 cm Routing Speed – 1500 mm/min maximum Resolution – 508 dpi adjustable Lifetime Estimation – 10,000 hours […]

Compact Wind Turbine Generates Up to 800 Watts, Outputs 12V or 24V DC

If I had to install some equipment at home were the mains are not easily accessible or would result in long cables, I’d immediately think about issuing solar panels to charge a battery, and discard the idea of using a wind turbine since in my mind those are really large and need to be fitted to a tall pole to be effective. But I’ve recently come across a relatively compact wind turbine that generates up to 800 Watts and outputs 12V to 24V DC. Key features and specifications: Rated Power – 800W Voltage 12V/24V Generator – 3phase AC PMG Rated wind speed – 11.5m/s Safe wind speed – 55m/s Wind direction auto adjustment Number of blades – 3 to 6 Windwheel diameter – 1.35m Material – High-strength PA66 and fiber-reinforced nylon Temperature Range – -40℃-80℃ Those are the specifications for the model I found on Banggood ($295.99), and I have […]

Brume-W Pocket-Sized Wireless Gateway Runs OpenWrt or Ubuntu (Crowdfunding)

GL.iNet Brume-W (GL-MV1000W) is a “pocket-sized wireless gateway for edge computing” that supports high-speed VPN up to 280Mbps with WireGuard, AdGuard ad-blocking software (AdGuard), and Tor. The device features three Gigabit Ethernet ports and built-in 2.4 GHz WiFi 4 connectivity, but it also supports Alfa AWUS036AC and AWUS036ACS USB WiFf USB dongles for users wanting dual-band WiFi 5 (AC) networking. The router ships with OpenWrt pre-installed, but also supports Ubuntu. Brume-W specifications: SoC – Marvell ARMADA 88F3720 (aka ARMADA 3720) dual-core Cortex-A53 processor @ 1.0 GHz with packet processor/network accelerator System Memory – 1GB DDR4 Storage – 16MB NOR flash and 8GB eMMC flash, MicroSD card slot up to 256GB Connectivity 3x Gigabit Ethernet ports (1x WAN + 2x LAN) Built-in 2.4 GHz 802.11b/g/n WiFi 4 up to 300 Mbps with external WiFi antennas Support for external 802.11ac WiFI 5 USB dongles USB – 1x USB host port, 1x USB-C […]

Mythic Beasts, miniNodes Offer Raspberry Pi 4 Hosting Services

Mythic Beats is the company offering hosting services for the Raspberry Pi website, and following Eben Upton proposal they decided to host the website on eighteen Raspberry Pi 4 boards, fourteen of which used as LAMP (Linux, Apache, MySQL, PHP) servers, as well as two used as static servers with Apache, and the final two used as memory store using memcache. Two days before Raspberry Pi 4 8GB RAM launch, they tested the implementation with “normal” traffic (e.g. around one million visitors a day), and the day of the launch, tens of millions visitors came to the website, and it failed, but not because of a failure of the Raspberry Pi cluster, but instead due to a Cloudflare glitch. This is all explained in Raspberry Pi blog. This is all for internal use, but you could also get your own hosted Raspberry Pi 4 board, as Mythic Beast recently added […]

Report: Most DS18B20 Temperature Sensors Sold Online are Fakes or Counterfeit Parts

We’ve already covered counterfeit components with a method to detect STM32 fakes, and several years ago, FTDI decided to take action by bricking clones of their USB to serial chips, although they’ve fairly quickly reversed course following the backlash. But Chris Petrich decided to look at another type of component: Maxim Integrated DS18B20 temperature sensor often found in waterproof temperature probes. His team bought over 1000 waterproof probes or bare chips from more than 70 different vendors on eBay, AliExpress, and online stores in 2019, and found the vast majority to be fake, counterfeit, or clones. So if you have such sensor not quite working as expected, you likely bought a clone as some of the counterfeit sensors do not work in parasitic power mode, have a high noise level, a temperature offset outside the advertised ±0.5 °C band, do not contain an EEPROM, have bugs and unspecified failure rates.

Ignitial Tukhla High-End Open Source Hardware NXP i.MX 8QuadMax SBC in the Works

[Update: The European company that initiated the project is Ignitial based in the west of France. So while we refer to the board as Olimex Tukhla in the post, it will be offered as Ignitial Tukhla once it becomes available] Most open-source hardware Arm Linux SBCs are optimized for cost, and there are few higher-end boards with extensive connectivity designed for professionals. Beagleboard X15 would be one of the rare examples currently available on the market, but it was launched five years ago. One European company noticed the void in this market and asked Olimex to develop a high-end open-source Linux board with a well-documented processor. They ruled out RK3399, and instead went Olimex Tukhla SBC will be powered by NXP i.MX 8QuadMax, the top processor of i.MX 8 family with two Cortex-A72 cores, four Cortex-A53 cores, and two real-time Cortex-M4F cores. As you can see from the screenshot above, […]
