D1 Mini Breakout Board

A board I wish I made a year ago!

This is a board that breaks out the pins of the Wemos D1 Mini ESP8266 board to screw terminals, has a prototype area and a barrel jack connector for projects that need more amps than can be supplied via USB.

I wanted to make this board because I found myself making a similar style board out of perf-board a lot, where I would breakout some of the pins of the Wemos to screw terminals, add a DC jack and add

The Power Blough-r

The simplest way to strip 5v from a USB cable

You know that annoying thing if you have octoprint for your printer, where you turn off the printers power supply but the screen stays on because it's still receiving power from the pi?

This device is the simplest way to fix that, just plug it into your pi, and then plug your printers USB cable into this and your printer will be be fully operational when it's own power supply is on, but fully off when its not.

Bar Graphs on a RGB Matrix

Dynamically fitted graphs for set areas

For one of my Saturday Streams I decided it might be fun to play around with graphs on the RGB LED Matrix.

As I'm sure you have heard me mention a lot, these RGB LED Matrix displays are one of my favorite displays you can use for Arduino. They are relatively cheap and easy to use, you can check out the video I made on it here:

I decided that bar charts would be a good type of chart to

Lightpipe 7-Segment Display

3D print + Light up shoe laces + neopixels = a winning combination!

A while ago I made a project that displayed the fastest route home based on live traffic conditions using Google Maps. It used through hole neopixels to display each route. Some feedback from that project was "wouldn't it be cool if the entire route lit up rather than just LEDs along it". That suggestion led me to light pipe but I never got a chance to try it out.


So inspired by cob LED segment displays that Seon

3D Printing Revisited

Time to get back on the 3d printed horse

I have owned a 3D printer for over 2 years and I really haven't made full use of it. To be honest I've never really gave it a good go. 3D printing is a skill that needs to be learnt like any other and at the same time that I was learning how to use my printer was when I was starting to get into Arduinos, and if you are familar with my stuff you'll know which hobby won out!

Twitch Draws On My LED Matrix

And no one drew anything inappropriate!

On a recent live stream (BrianLough is my Twitch name) I revisited my "Twitch draws on my LED matrix" project. It's pretty amazing to see people being able to draw pretty cool things using very basic commands! Check out the examples below!




Pretty impressive right!? The best part was nobody at any stage tried to draw anything inappropriate, a great success I would say, good job everyone!

Well done

In future I would like to set up a "Twitch

Block ads on all devices on your network

Block Ads using a Raspberry Pi with Pi-Hole

Tired of seeing tonnes of ads? Well here is a really cool solution using your Raspberry Pi. Pi-hole is a software that replaces your DNS server and strips out any requests for domains that are known for serving up ads. Check the example below!

Before Pi-Hole:

After Pi-Hole:

The whole setup should only take about 30 minutes. All details can be found in the video:

Parts Needed:
This should work on any Raspberry Pi and is a great way to

Live Streams

I do my live streams on Twitch, come stop by for a chat!

I live stream working on projects and libraries on my Twitch channel.

Stream Times (Dublin/London timezone):

  • Monday at 21:30
  • Saturday Mornings at 08:00

Here is a sample Live Stream were we code a webpage that is able to draw on an LED matrix in real time.

To ensure my YouTube channel is not diluted with just live streams, as I can make live streams much faster than I can make videos, I only upload the Monday streams

Arduino Libraries

I'm really proud to have created some Arduino libraries that people use!

I think the libraries are the best part of the Arduino ecosystem, there is a huge range of libraries availble ranging from all different types of functionality, whether it's a library for getting a screen working or fetching data from a particular end point, it enables more and more people to create awesome and interesting things faster.

I really wanted to be able to give something back to the Arduino community after so many had provided countless libraries and code

Welcome to!

All the cool kids had blogs so I wanted one too.

My name is Brian Lough and welcome to my new blog!

I'm a Software Developer who has a large passion for working with Arduinos and microcontrollers. I love building projects that interact with the physical world, I'm not sure that will ever get old to me!

In this blog will mainly be supplmental to my YouTube channel, but it will also provide me with an opportunity to post some things of interest to me that don't really fit into the
