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.

Deck out your ride with an Arduino-controlled spoiler
Car spoilers can provide downforce for better performance, or simply give the appearance of speed. To take things to another level, Michael Rechtin designed his own custom wing that doesn’t just sit there, but pitches up and down via a pair of servos.
The system utilizes an Arduino Nano along with an MPU-6050 for control, adjusting itself based on his Mazda’s movement, and powered is supplied by a LiPo battery. Suction cups are used to attach the spoiler, so installation appears to require no actual modification of the car whatsoever.
