LED clock assembly
Recently I brought this assembly kit Bluetooth led clock at Banggood: http://www.banggood.com/DIY-AT89S52-Rotation-LED-Electronic-Clock-Kit-51-SCM-Learning-Board-p-965849.html Here are some pictures showing the process: The assembly was relatively easy. Except the SMD leds, resistors, transistors and capacitors! They were a little bit harder to solder. Unfortunately the Bluetooth feature didn’t work with my actual mobile phone, that has Android 4.4 […]

Adafriut webIDE BETA release
Yeah the next prank from Adafruit! They build up their own web-based development IDE. At the moment it’s only in beta state but I think the chance is very high that it will become very awesome. Right now it runs on Raspberry Pi and BeagleBone and supports Ruby, Python and JavaScript. The genius part is, that the code […]
Get GPIO pin overview (pinout)
On Banana Pi you can call: $> gpio readall This should give you an pinout like that: +———-+-Rev2-+——+——–+——+——-+ | wiringPi | GPIO | Phys | Name | Mode | Value | +———-+——+——+——–+——+——-+ | 0 | 17 | 11 | GPIO 0 | OUT | High | | 1 | 18 | 12 | GPIO 1 […]
Raspbian for Banana Pi default user password (for bananapi)
The default password for the default user bananapi on a Raspbian for Banana Pi operating system is bananapi. You should change it to a secure password on first connect via ssh. Therefore you can use: $> sudo passwd bananapi
Set static IP
Sometimes its necessary that your machine gets a static IP-address. For example if you want to run a server or a other service on that machine. On Debian based machines you can do this by: Edit /etc/network/interfaces (f.e.: with nano) auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.88.6 netmask 255.255.255.0 […]

Shred files – securely delete files, folders or partitions
To shred files or partitions securely: $> shred -vun <loops> <File1> <File2> $> shred -vzn <loops> <Device> loop is the count of the loop beginning with 0 (3 means 4-times)!!! You can get the partition table as described in List of partitions or List, partitioning and format drives. If you want to shred a directory recursively, you […]
List, partitioning and format drives
List all devices: $> sudo fdisk -l That will give you an overview about all your drives like that: Disk /dev/sda: 256.1 GB, 256060514304 bytes 255 heads, 63 sectors/track, 31130 cylinders, total 500118192 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): […]
