Hackaday contest

I stumbled upon the new hackaday contest: http://hackaday.com/2013/12/03/new-contest-win-one-of-20-microchip-fubarino-boards/ (admittedly I did so very late, because the deadline is in less than 24h ), but I thought my MWO Controller is the perfect candidate to manipulate into an entry for that contest.

By adding the following lines of code:

// HACKADAY CONTEST MODIFICATION
  if ((profile.key[0]-0x4000) == 32 &&
      (profile.key[1]-0x4000) == 30 &&
      (profile.key[2]-0x4000) == 32 &&
      (profile.key[3]-0x4000) == 32 &&
      (profile.key[4]-0x4000) == 36) {
    // first row of button matrix spells "31337", so we output the hackaday URL on every keypress
    Keyboard.println("http://hackaday.com");
    return;
  }
  //*******************************

to the fireKeyEvent function within the event.h file the MWO Controller will print out “http://hackaday.com” whenever the first 5 buttons of the matrix on the touchscreen are assigned keys to spell out “31337″.

MWO Controller

MWO Controller / Custom Keypad with Touchscreen interface

Introduction

So I’ve started playing Mech Warrior Online recently and noticed the huge amount of key bindings required to adequately control a mech. That inspired me to design and build a custom controller that would allow me to easily configure and switch between different key layouts on the fly. And so I designed and built a 26 key, touchscreen equipped controller.

Upcoming articles

So, it’s been a while since I wrote any articles, mainly because I’ve been busy in general and also busy making things. It’s just more fun to do things, rather than write about them.

But since I didn’t want any potential reader who stumbles across this site to think, that it is abandoned by the author, I decided to start posting updates on what’s to come (hopefully on a regular basis).

Now without further delay, the updates…

WiFi Tank Drone

Introduction

This is more a proof of concept project than a finished project. I’ve always wanted to build a tank drone controlled over WiFi with Video streaming and GPS navigation. So when I discovered the Carambola WiFi board back in 2011 I finally started to actually build it. This prototype has taken me about a week to develop, as such it is still rough around the edges. I wanted to test a few concepts with it to further my knowledge towards the end goal of creating a flying drone.

Glass Cabinet RGB LED Light

Introduction

This is a project that I’ve done for a friend. She desperately needed a cool light for her glass cabinet that didn’t take up too much valuable space. So I designed this light to be as flat ass possible and to perfectly fit the floor panel of her glass cabinet. To ease control of the light I integrated a Bluetooth module into the design and wrote a small Android App to connect to it.

I’d say it turned out quite nicely.

kinect_plus_cubieboard

Cubieboard Fileserver + Kinect

So I’ve recently bought a Cubieboard to use it as a file server. If you look closely at this posts featured image (or if you’ve already clicked on the link) you might notice why I picked this particular embedded board. Exactly, it has a SATA port for connecting a standard HDD or SSD to it. This should offer a huge performance improvement over USB connected HDD’s (albeit the Cubieboard still only has a 100MBit/s Ethernet interface).

I will describe what I’ve done so far with the Cubieboard and the Kinect, but it’s all on the “Hello World” level, so this post will mainly serve as a reminder for me, so that I don’t forget the basics.

Update to: Python USB and TEMPer V1.2

Unfortunately my every day job has gotten most of my time lately and I haven’t been able to make much progress on anything. But today I had some time to play around with my new cubieboard based Fileserver and the old Microsoft Kinect I had laying around for a while now (I’ll write about that in the next post). And while I was playing around I got reminded of a very powerful Python library called numpy, which helped me solve a minor problem I still had with my TEMPer USB driver. Previously I had a problem with reading temperatures below zero, as the TEMPer protocol uses a signed integer as a datatype for the temperature and Python doesn’t have a native one Byte signed integer. But luckily numpy remedies the problem with its own datatypes, among them a one Byte signed integer (int8). So I shortly turned away from my Kinect/cubieboard endavour to fix the TEMPer driver. The solution is simple, I add numpy to my imports and convert the retrieved temperature value to numpys int8, so the final code looks like this:

Python USB and TEMPer V1.2

In preparation for a bigger project I’ve recently written a driver for the USB Temperature Sensor TEMPer V1.2. As this is going to be part of a bigger project that will interface with these sensors I wanted to integrate the driver with the project. So I decided to write it in Python.

ipv6_ipv4

Unitymedia and your IPv6 Home-Server

Introduction

If you’re like me, you’ll have a home server running some services you want to reach over the Internet when you’re at work (or something like that). Furthermore if you’re like me you’ve changed your ISP to get more bandwidth for your home server. I’ve recently switched to Unitymedia and that was the end of my home-server availability.

Why you may ask? Because Unitymedia only provides IPv6 addresses to their new customers, so effectively, if you’re in the same situation as me, you won’t be able to reach anything on your home network (not even your router) via the routers assigned IPv4 address. But don’t worry, in this post I’ll explain how to solve your problems with accessing your home-server.

3D_Display_Prototype

Proof of Concept: DIY Pyramid shaped 3D Display

This is going to be my first post about one of my later projects (03/2011): The DIY 3D Display prototype. I don’t have anything documented about it, after all it was just a proof of concept. But the youtube Video generated enough comments that I will try to come up with a documentation in the next post.

In this post however I’m going to explain how I got to make this prototype and I will talk a little about how it works. For those only interested in the technical stuff head on to How it works.
