So the rough plan is to get a good looking nautical map printed on the front of the PCB using this new Colourful Silkcreen PCB option at JLCPCB that was added to EasyEDA PRO. Then, inspired by the article ``THE SCIENCE OF REVERSE MOUNTED LEDS'', mount...
14 years ago I built my own CNC machine. At that time, CNC were running with Xp PC using parallel port. Gcode eaten by Mach3 software and sent to steppers controller board using the parallel port pins. This machine, although dusty and rusty, ...
1. Concept As a practical application of my PERSEUS-9 computer for astronomical observation, I decided to create a hardware and software system to display the celestial coordinate system of an equatorial mount. This computer is not suited to perform...
In the previous tutorial we discussed the word organization, setup and configuration of DF2301 Offline voice recognition module. Today we will make a home automation project using the same module with Solid state relay interface for small loads. But...
It’s been very long, I am making circuits on PCB and breadboard. But while testing the circuits on breadboard the main problem is to make the connections and supply it with a logic power. Digital circuits can be easily made but on the other hand breadboard...
Hardware Package & Size The form of the cartridge comes naturally as it is the same as a DIN socket. It is cylindrical with same diameter as the wrapper of the connector so that it replaces it, and the length is as small as possible. Interfaces...
Hi. So this is the story: My interest/knowledge of embedded stuff was always around 32bit MCUs and a little bit of FPGA/CPLD devices. Mostly in audio signal processing world. The embedded Linux always was for me something out of my scope. Back in the...
The initial board The initial circuit was published bye "Mdog" and did exist into two versions "solo" and "4axis". Both of these boards rely on the Ti LMD1845 H bridge circuit. The LMD18245 is a full-bridge power amplifier with 2• DMOS Power Stage...
Introduction. If you love DIY electronics, you’ve probably heard about Arduino. It’s a fun and simple way to get into robotics and programming. But did you know you can also use it to send text messages and make phone calls? That’s right! With a little...
