Clap activated Nixie tube thermometer – Part 1

Years ago I bought a bunch of IN-14 Nixie tubes from the Ukraine and I had them lying around since then. I always wanted to use them for a custom device and so I decided to finally tackle this project and build something that utilizes this almost ancient way of displaying digits, but for now I didn’t want to build a Nixie tube clock (I thought that was a bit of a cliché thing to do and for now I’ve had enough of fancy hipster clock projects), so I thought: Why not build a thermometer for my room that can be activated by clapping?

USB volume knob for Windows, Mac OS and Linux – Part 1

In this article I want to take a look at the Atmel ATmega32U4 8-Bit microcontroller, which has a USB 2.0 controller built-in and therefore should enable anybody to make their own USB compatible HID devices. I’ll try to show the process by building a USB volume knob, which will allow the end-user to change the volume or completely mute all sounds on the device it is connected to.

How to connect your Arduino to the Internet with the ENC28J60

I’m currently working at a custom messaging system, which will users to exchange encrypted messages. To achieve this, I bought a ENC28J60 powered ethernet module, which can be used to connect an Arduino to the Internet (or any other microcontroller that supports SPI). In this short article I want to show you how to connect this module and get it up and running in no time! Continue reading How to connect your Arduino to the Internet with the ENC28J60

A long overdue update

So, it’s been quite a while since I published something new and I thought that it’s about time, that I post a short update about what’s going on. I was quite busy working on a robot project and all the articles are already done and sitting around, waiting to be published. But I’m still not fully satisfied with the build, so I guess, that I’ll put this aside for a while and write about different topics instead.

However, here are some pictures of what I’ve come up with so far and I’ll publish the series as soon, as I’m happy with the result.

The end of net neutrality?

As most of you might have already heard, the chairman of the FCC, Ajit Pai, announced to revert Title II of the Communications Act from 2015, which allowed the FCC to regulate internet service providers (ISPs) and therefore forbid certain business methods, which might discriminate some service providers on the internet, which de-facto puts net neutrality to an end.
