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 […]

SC-10 SHARK is a Faster 3D Printer with Optional Laser Engraving, Bicolor, and Auto-leveling (Crowdfunding)
Printing a 3D model usually takes hours, if not days, so anything that can speed up the printing time while keeping the same quality should be welcomed. LOTMAXX SC-10 SHARK 3D printer promises to reduce the standard print time by up to 30%. How did they exactly make a faster 3D printer? Thanks to “Aeolus Heat Dissipation system” (AHDS) with four fans to cool the nozzle and “S Move System” (SMS) helping the motors travel at a high speed. The printer also happens to be a multifunction printer with support for laser engraving and bicolor printing. SC-10 SHARK launched on Kickstarter several weeks ago and raised over $200,000 US from around 620 backers with 12 days to go. SC-10 SHARK 3D printer key features & specifications: Molding technology – FDM Print Speed – Up to 200mm/s; normal speed: 45-90mm/s Printing Accuracy – +/-0.1mm Layer thickness – 0.1 to 0.4 mm […]
Getting a 3-inch Smartphone in 2020? You can with Unihertz Jelly 2 (Crowdfunding)
Most smartphones have 5″ or larger displays these days as it’s just more convenient to read emails, browse the web, or play games, than the smaller displays we had ten years ago. But some people may still prefer smaller smartphones that are lighter and really fit into any pockets. Those are just pretty hard to find, luckily some companies such as Unihertz are filling the needs for this niche market. Two years ago, the company introduced the Unihertz Atom smartphone with a 2.4″ display, and earlier this year launched Atom XL 4″ smartphone, but the company is now preparing to launch a new crowdfunding campaign for Jelly 2 smartphone powered by a MediaTek Helio P60 processor and equipped with a 3-inch display. Unihertz Jelly 2 specifications: SoC – MediaTek Helio P60 octa-core with four Arm Cortex-A73 up 2.0 GHz and four Arm Cortex-A53 up to 2.0 GHz, Arm Mali-G72 MP3 […]
AirTab 15.6″ Portable Display Provides 2x USB-C Inputs (Crowdfunding)
While portable displays have been available as far back as at least 2012, they’ve become more popular in recent years as they can both offer a secondary display to your laptop, or add a larger screen to your smartphone. In the last two years, we’ve already covered BlitzWolf BW-PCM1, T-bao T15A, TAIHE Gemini (which ended up being a failure), Airview, and Desklab among others. But apparently, there’s room for more with the launch of AirTab, a 15.6″ portable touchscreen or non-touch monitor, on Kickstarter that’s already surpassed its $10,000 funding target. AirTab specifications: 15.6″ display with 1920×1080 resolution up to 60 Hz refresh rate; 4ms response time; 256 cd/m2 brightness Touchscreen – Air Touch model only USB – 2x USB-C ports Power Supply – Dimensions – 335 x 245 x 4.9 mm Weight – 500 grams AirTab comes with a foldable magnetic cover that allows the display to be used […]
CrowPi2 Raspberry Pi 4 Laptop Doubles as Electronics Learning Kit (Crowdfunding)
CrowPi portable learning kit for Raspberry Pi 3 B+ and Pi Zero boards was launched in 2018. It comes with a 7″ display, several sensors, buttons, a breadboard, and more all packed in a small suitcase. Elecrow has now started a new crowdfunding campaign on Kickstarter to fund the second generation portable electronics learning kit: CrowPi2 which looks much more like a laptop than a suitcase found in the first model thanks to a large display, and a detachable keyboard placed on top of the electronic prototyping/learning area. It’s also more powerful thanks to the latest Raspberry Pi 4 SBC. CrowPi2 specifications: Compatible Raspberry Pi boards – Raspberry Pi 3B/B+, Raspberry Pi 4 Display – 11.6-inch 1920×1080 IPS screen Camera – 2MP camera Audio – Built-in microphone and stereo speaker; 3.5mm audio jack Keyboard – 2.4GHz detachable wireless keyboard (QWERTY only) with touchpad Sensors and Modules under the keyboard: Displays […]
STM32 based Indoor Air Quality Sensor Connects to Raspberry Pi or Arduino (Crowdfunding)
