James Bruton demonstrates the Coanda effect with an Arduino-controlled rig
The Coanda effect, as you may or may not know, is what causes flowing air to follow a convex surface. In his latest video, James Bruton shows how the concept can used as a sort of inverted ping pong ball waterfall or staircase.
His 3D-printed rig pushes balls up from one fan stage to another, employing curved ducts to guide the lightweight orbs on their journey.
The fan speeds are regulated with an Arduino Uno and motor driver, and the Arduino also dictates how fast a feeder mechanism inputs balls via a second driver module. While the setup doesn’t work every time, it’s still an interesting demonstration of this natural phenomenon, and could likely be perfected with a bit more tinkering.
Sabrent RocketQ Battleship SSD teased with 64TB at PCIe 4.0 speeds
Sabrent goes for gold in the first days of 2021 with a tease of its RocketQ Battleship SSD which has 8 x 8TB SSDs for 64TB.
This DIY electronic puzzle lets you construct circuits by plugging blocks into a 3D-printed board.
When ‘victorqedu’ was a child, he had an electronic puzzle game that enabled him to make various circuits from electronic components, such as lights, buzzer sounds, and even a radio. This fascinated him, and as “a programmer with a lot of hobbies,” it certainly had some influence on his life. He wasn’t able to find this game for sale today, so decided to build his own 3D-printed version, with component blocks that plug in to complete various circuits.
DIY Soil NPK Meter || Measure Soil Nutrient Content using Soil NPK Sensor & Arduino
In this video, we will learn about the interfacing of Soil NPK Sensor with Arduino. The soil nutrient content can be easily measured using NPK Soil Sensor & Arduino. Measurement of soil content N (nitrogen), P (phosphorus), and K (potassium) is necessary to determine how much additional nutrient content is to be added to soil to increase crop fertility.
The soil fertility is detected using NPK sensors. A major component of soil fertilizer is nitrogen, phosphorus, and potassium. The knowledge of the soil nutrient concentration can help us to learn about nutritional deficiency or abundance in soils used to endorse plant production. Apart from measuring Soil NPK, you can also measure Soil Moisture Content using Soil Moisture Sensor, which is explained in my one the previous video.
How to Fix Z Banding/Ribbing in 3D Printing – 5 Easy Solutions to Try
Most 3D printer users have experienced Z banding or ribbing issues at some point in their 3D printing journey, same with me. I wondered though, how do we fix this Z banding issue, and are there simple fixes out there?
How many Arduinos does it take to knock a server offline?
This isn’t a hacking tutorial but we will take a look at the anatomy of a DOS and DDOS attack to get an idea of how a small IOT device like an Arduino with an Ethernet Shield can be used to cause a server to do massive amounts of work.
Touch Sensor based car engine starting system with Arduino (Project Simulation 1)
This project uses a touch sensor, two push-button, Arduino board(ATmega 328), LCD, and a relay with DC motor
Robots Made of Ice Could Build and Repair Themselves on Other Planets
No matter how much brilliant work the folks at NASA and JPL put into their planetary exploration robots (and it’s a lot of brilliant work), eventually, inevitably, they break down. It’s rare that these breakdowns are especially complicated, but since the robots aren’t designed for repair, there isn’t much that can be done. And even if (say) the Mars rovers did have the ability to swap their own wheels when they got worn out, where are you going to get new robot wheels on Mars, anyway?
This Ryzen Handheld is Amazing! – AYA NEO First Look
We finally have some good competition in the handheld PC gaming market. The AYA NEO is a Ryzen 5 gaming handheld that is launching later this month on Indigogo. In this video, we take a look at a prototype version of the device and do an extensive 5w test of the processor.
