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.

I’m currently working at a custom messaging system, which will users to exchange encrypted messages. To achieve this I bought an 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
Due to the upcoming release of Skyrim VR this Friday (17th of November) I decided to get myself a PlayStation VR headset, which is the cheapest proper VR Headset currently available with prices starting at 350€ for just the Headset or 400€ for the starter kit which contains the Headset, two motion controllers and the PlayStation Camera. I wanted to share my experience with this system and tell you about some tips and tricks that I discovered during usage. Continue reading PlayStation VR Test and Review
Oh yes, Christmas! It’s almost that season of the year again. And to shorten the time between the 1st of December and Christmas Eve’, I thought about a bit more interesting advent calendar than one, that only has chocolate in it. This electronic advent calendar offers a riddle that you can create for a loved one or a friend and give it to them so they can try to solve it before Christmas arrives. It offers a clue every day and it presents all unlocked clues on a website that runs on the device itself. The only two things it needs to work is a power supply and a WiFi network it can connect to. And the best thing is: It is really simple to build and it can be re-used every year and it can also be used for other occasions (for example Valentine’s Day)!

Well is it? If you expect a very short answer from me, I’d say: absolutely, even if you just want to regularly back up your data, which is a very good idea. But in this article I want to take a look at some ready to buy consumer NAS devices, a cost-effective self-built and self-hosted one and some well-known cloud services and I want to compare how much they cost if you use them for one, five and ten years. This is not a product test and I won’t go into too much detail, I just want to sum up some options you have and when you should consider getting one or the other option and how much they will cost you. Continue reading Is it worth buying a NAS or cloud space?
In this article I want to cover an alternative I’ve come across while building the “real” word clock project. This version will not feature a 12×12 LED-Matrix display. Instead it’s made with LED strips and only the significant words on the clock can light up. With this method you can’t display custom messages, but the whole build won’t cost you as much either. Read all about this build in this article or watch this video:
