Everyone playing with electronics these days knows about LED strips made of dozens or hundreds of individually addressable RGB LEDs. I love them and make great use of them in the nootropic design Lumazoid music visualizer. But what about incandescent lamps? Old-school light bulbs with a filament have a soft warm glow that you just can’t get from LEDs. Wouldn’t it be great to be able to control a bunch of la ...

As I was mentioning in my 1000.1000 Hardware selection, I have opted for the cool RFM69HW radio module. Weirdly enough, in quite a few sources (big distributor and ebay) the higher power HW module is cheaper. So there ie no reason not to get the higher power module, given quantity discounts. But I want it to operate at lower power most of times. The datasheet does not show any differences at lower power, so ...

After many hours of work I’m very happy to finally publish all the sources for the ESP8266 PlaneSpotter project. It is not yet really in a V1.0.0 state but I’m sure with the help of the community it will quickly get better. While this post is more a “making-of” you can find build instructions on Github: The Beginnings A few months back I had already built and published a PlaneSpotter project for the tiny OL ...

Online circuit simulators are getting more popular day by day. Electronics hobbyists, as well as professionals, use circuit simulators often to design and check circuit diagrams. The best thing about online simulator is, you don’t have to install anything at all on your PC or laptop. All you need is a browser and a stable internet connection. Work from anywhere just by opening the online circuit simulator w ...

The Makerspace has its own equipment (and a meetup page), which is installed in a multi-purpose room during the events. Library staff also do out-reach events (to schools for example) and in-house courses and workshops (Arduino for example), and the Makerspace has a loose alliance with the Surrey and Hampshire Makerspace, which also meets in Gulidford. Then the library has an alliance with the near-by Unive ...

How to work with Light Emitting Diode (LED) in Proteus In this post we will be learning on how to use the “Light Emitting Diode (LED)” component in Proteus simulation software. In case you have not got on through the basics of Proteus, here is the link – Proteus PCB Design and Simulation Software – Introduction. Note:- You may also read our 1st chapter on Proteus Tutorial Series – Switches and Relays in Pro ...

This small Python script takes a KiCAD board (.kicad_pcb file) and produces a 2D nice looking drawing of the board as an SVG file. This allows you to quickly and automatically create awesome pinout diagrams for your project. These diagrams are much easier to read than a labeled photo of a physical board or an actual KiCAD design. You and your users will love them! Dependencies This script requires the pcbne ...

The “ESP8266 OLED SSD1306″ is an open source library which allows you to control those pretty OLED modules from our beloved ESP8266 module. Fabrice Weinberg cleaned up all the ugly pieces of code which I initially wrote caused by my near C/C++ illiteracy. He also added support for Pasko’s BRZO I2C library which is partially written in assembler and allows a much higher throughput over the I2C channel. Fabri ...

In this article, we are going to build an Arduino Real Time Clock using DS1307 RTC Module and 16×2 LCD module for display. First of all, let’s see how to interface RTC Module to Arduino. There are different kinds of RTC modules available in the market. We are using the most common RTC module comes named DS1307 IC, an LCD module and Arduino Uno for this tutorial. Interfacing an RTC module to Arduino is prett ...
