Coding nRF52 with Rust and Apache Mynewt on Visual Studio Code

The nRF52 Microcontroller by Nordic Semiconductor is an awesome gadget with powerful Bluetooth Low Energy networking capability. It’s affordable too… For under $8, I can buy an EBYTE E73-TBB Development Board with onboard nRF52 (photo above). And it works like a supercharged BBC micro:bit (based on the older nRF51) in a smaller, cheaper form factor!Powered by an Arm Cortex-M4 CPU (hardware floating-point) with 64 KB of RAM and 512 KB of Flash ROM, the nRF52 has plenty of capacity to run modern e...

A Cheaper Alternative to Relays When Driving 240 VDC loads --- 8-MOSFET

Why Choose 8- MOSFET?Compared with relays, 8-MOSFET is more cheaper to drive four high-current loads (24 VDC at 10 A) and four high-voltage loads (240 VDC at 2 A). For applications that require fast, clean switching times, it will achieve the job more quickly and quieter. Also, it has nearly unlimited longevity with high endurance under heavy loads.What’s more, it employs industrial-grade, pluggable connectors, which makes it easy to use. Thanks for its scalable feature, and only the I2C interfa...

Mesmerizing Ferrofluid-Display: Silently Controlled by Electromagnets

The team behind this project is currently discussing options for making a smaller, more affordable, ferrofluid-display for more realistic replication by hobbyists. When that work is done we will write a more detailed, step-by-step, Instructable and link to it here. To give a realistic perspective of the timeline we're working by, it is unlikely that such a project will be done before the end of 2021. It's developed entirely on a hobby basis by students at the University of Oslo.All that being sa...

DIY Sensor Projects Part 1---Innovation & ImplementationS2E2

A sensor converts stimuli such as heat, light, sound, and motion into electrical signals. These signals are passed through an interface that converts them into a binary code and passes this on to a computer to be processed. Today, let’s see how makers use plenty of sensors to build their awesome projects! 1.Image Sensor & Digital Camera The main purpose of sensors is to collect data from the surrounding environment. For example, it might be like our eyes, which can capture images. Sean made ...

Building a Visual Bloom Filter with Raspberry Pi, Python and Unicorn Hat

Bloom filters are a probabilistic data structure that I’ve wanted to learn more about for a while. When I started reading up on them, I found a lot of the material to be quite dry and theoretical, so I thought I’d try and implement one in hardware somehow and make my own visual learning aid.So what’s a Bloom filter? Wikipedia says:" A Bloom filter is a space-efficient probabilistic data structure, conceived by Burton Howard Bloom in 1970, that is used to test whether an element is a member of a ...
