With everything simulated we now need to build it. I've decided to use one of the Nordic nRF52 MCUs. There are several which can implement direction finding: nRF52811, nRF52820 and the nRF52833. These all have a 64MHz Arm Cortex M4. However the nRF52833...
I've got four EastRising LCD modules from www.buydisplay.com.I've got a Teensy 3.0 from Paul StoffregenI've got a workspace stocked with all kinds of tools and components.The LCD modules comes with a FPC cable so I ordered some 30...
How do we get the analog signals from the respiratory pressure sensor and the 8 expressive buttons via the network to a software synthesizer? We need a MCU and PHY, right? We will use one of our designs we already have at hands from an other project:...
Arduino UNO Pinout and Board descriptionI will explain the description of the Arduino UNO Pins and the board in the post. Arduino Uno is a standard board of the company, even though other boards e, g. micro, Nano, mega, Leonardo,...
Herring Backplane 3.3vUntil recently, I have been maintaining two versions of the Herring system - one with 5v-compatible components and another for 3.3v. The backplane regulates the 12v DC input so it's easy enough to install a 5v regulator in one and...
OverviewThis is a scientific calculator I built that uses RPN notation. Features:BCD number format with 1-255 placesInternal accuracy configurable from 6 to 32 decimal placesTwo separate 200 level stacksOptional scientific notationFunctions: (a)sin,...
3D printed part files can be seen on ThingiverseWhy I made this Project?I made this project coz i feel there is so much of technology available but still there are many parts of the world where there is either not an awareness or lack of resources to...
Getting to Know the ComponentsIn this step I give some important information about the robot’s components and how to prepare them for mounting.In the first place, the heart of the robot: an Arduino UNO R3. Although I am using an Arduino UNO, you can...
As the KIT1 is open source, talented community makers often brought upgrades to this versatile IOT platform. Here' the work of Akos, that adapted the KIT for battery use and also built a plexiglass enclosure.Last week I’ve assembled a KIT1 and posted...
This project takes inspiration from many of the other similar low-power loggers on this site, but especially from the Cave Pearl project which I discovered about halfway through prototyping on this one. Instead of using several cheap modules,...
GOOGLE ASSISTANT AND ESP8266 BASED SMART APPLIANCE CONTROL GOOGLE Assistant To Control your Lights & Fan Home automation has become very common now days and people are using IoT to automate everything in their home. Today, I...
The Arduino Nano is one of the most popular versions of the Arduino. The low cost of Arduino Nano work-alike clones is one attribute that drives the popularity of the nano design. The use of an ATmega328P makes it compatible with a substantial collection...
