searching for a cheap small 3,5 inch monitor

Well, after some research on conrad (german radio shack :-)) and ebay found something.

This small display uses the video connector. So it`s not too sharp. But small, cheap and really bright.

The price was about 25 € including shipping and vat.

This picture is not too good. The display is sharper than it seems.

Yes, i started Open Arena 🙂 of course just for the test!

Well, i have to use my screwdriver….

Well, here is just the panel with driver board itself.


It`s really small and has 2 screw holes on each side for a easy fit.


Configuring WPA2 using wpa_supplicant on the Raspberry Pi

By the way, this was extremely helpful getting my wifi dongle running with a hidden wpa2 connection running wheezy.


To use WPA2 pre-shared key on the Raspberry Pi, you will first need to add a network configuration to “/etc/wpa_supplicant/wpa_supplicant.conf”. Note the lack of space in “network={“.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

    ssid="Your SSID Here"
    pairwise=CCMP TKIP
    group=CCMP TKIP

After you have modified wpa_supplicant.conf, you will need to change the “wlan0” section of “/etc/network/interfaces”. For a static IP, it will look like this:

# allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet static

For DHCP, it will look like this:

# allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

After that, you will need to bring up the “wlan0” interface using “ifup”:

# sudo ifup wlan0

You may have to bring the interface down and then back up:

# sudo ifdown wlan0
# sudo ifup wlan0

First drawings and a paper cube


after some drawings later, i decided to create a paper cube to see how it could fit all together.

I will upload some Pictues of the drawings later as well as some ideas about a small circuit board for the power,

external connectors, power-on button and a secondary video out-out.

Maybe it could be helpful to put a audio amplifier on the circuit board?

Update 28th of april: Working on a audio amplifier…

I´m Gregor. I used the raspberry pi for a while and had a everday problem.

All that connectors, power plugs, USB Hubs and cables…..


Cable mess all around!

I need a all in one case.

So, hmm!

I like the cubic Apple Designs of Hartmut Esslinger in the past days  and so i decided to create a new really small device.

But much smaller!  Just a little cube.

Here you can read about my conclusions:

It should fit in my palm. hmm….

So, that was really my first reference point?!?! OK.

The cube should not be bigger than 11 cm about 4,3 inch.

Okay, so we need a small Display. Note more than 3,5 inches.

I need my paper pad now….
