Did you ever wanted your room decoration to be a smoothly fading light strip in a jar? Inspired by the Pimoroni firefly light I built my own variation with an ATtiny and two AA batteries instead of using a Raspberry Pi Zero and a huge battery pack. There are three LED strings that fade in a sine pattern. Two of them fade anti parallel at one of 16 adjustable speeds. The third fades differently at a second configurable...

I was tired connecting my cellphone with an old cassette adapter to my VW Golf with an Beta 5 in it. I needed something new, something cool. And here it is, a fully functional interface between the Beta 5 and any device you want to play the music with.

This project raised out of an ebay search: I just wanted to know if there is a solution to get an AUX input on the car radio. Yes there is, even complete mp3 players are available. But that’s not what I wanted – at first!

Then I started digging the web for more info about the protocol the radio talks to cd changers.
The idea was to build a tiny thingy that fakes a cd changer and simply enables the AUX input (as it is available in several online stores). But during the development my ambition became greater and I wanted to read the keys pressed on the radio to remote control my RPi.

In my current project I want to interface the FT220x over 1-bit SPI with an TI piccolo TMS320F28027.
After some trouble and various cups of coffee I managed the whole thing by implementing the SPI in pure software.

I wasn’t able to get it working with the built in tri-wire hardware SPI as the FT uses MIOSIO and MISO to send/receive data and status respectively.

Because there is no sample code available on the web concerning this problem I decided to publish my library here. Take a look into the datasheet for further information!

Sending data over SPI to the FT1248/FT220x is quite easy: Just send a WRITE_REQ (0x00) followed by the payload on MIOSIO.

Reading is a bit more complicated: We need to know how many chars to read. Well, send a READ_REQ (0x02), evaluate MISO and read data on MIOSIO if the FIFO is not empty.

My extension makes this problem to be a thing of the past! Rightclick on a selected tracking id: The context menu entry takes you directly to the DHL infopage of your parcel. On the optionspage you can make a list of urls where this extension should be enabled. In addition the language of the...

Have you ever heard of google cloud print? It allows you to add your printers to the cloud and share them. You can print on them from any device supporting this service, even if you are on another network. This sounds pretty cool, I gave it a try and I am really amazed.

None of my printers doesn’t support cloud print directly, so I need a google chrome installation to share the printer. But I don’t want to have my computer to run when printing remotely. There is a project called Google CloudPrint on Linux which allows you to use this nice service from the command line. At this point the dockstar or the linkstation joines the game.

[ratings] Since I installed pyLoad on my dockstar I used Jabber to get download statuses and add new packages. Then I updated pyLoad to v0.4.5 and saw there is support of an Android app. It's pretty cool though, you see every info you want to see when using a remote app. These three sections of the web interface are available: Overview, Queue and Collector. More or less the whole web interface is put into this app. There...

During the last days I was playing around with several kernel-configs and different release versions. Today a new version came out and I built it with the last config I used. In my build I additionally enabled XFS filesystem support and USB sound. If you install my kernel, you don’t have to change anything except the device ID concerning the LED if you come from gorgone’s heavykernel.

If anybody knows how to build a kernel with gspca drivers for webcam support I would appreciate a short mail!

[ratings] Auch mir ist aufgefallen, dass mein Defy oft die Verbindung verliert wenn eine Fritz!Box 7270 mit eingeschaltetem 802.11n benutzt wird. Bei meiner wöchentlichen Beschau einiger Blogs bin ich auf einen Beitrag von dev-eth0 gestoßen, der WLAN-N im Handy abschaltet und so das Problem umgeht. Zu dem Blogeintrag geht's hier: http://www.dev-eth0.de/archives/1002...

Es ist wieder an der Zeit den Ordner für die “Wallpaper-Diashow” zu erneuern.
Ich brauche ein Tool, welches mir ermöglicht schnell und unkompliziert verschiedene Dateien zu kopieren und gleichzeitig umzubenennen. Dies soll auch funktionieren wenn sich bereits bearbeitete Dateien im Zielordner befinden. Meine Lösung des Problems lautet D&D Renamer.
