Rob from SonicGoose.com has put together a tutorial on how to use Globe-S RTL Edition with RTL1090. Globe-S is a light radar viewer (similar to Virtual Radar Server, ADSBScope etc) meant to interface with the popular ADS-B decoding software RTL1090.
See the tutorial here.
A new beta version of the RTL1090 ADS-B decoding software for the rtl-sdr has been released. Currently, it seems only the GUI has been improved, but the author plans on soon adding the following improvements
See the Yahoo Groups release post here for the full build change notes, and download the beta from their website here.

Earlier in the week a video comparing a Discone to a Coax Collinear antenna for ADS-B reception was posted. The author of that video has now posted on his blog a tutorial on how he made the coax collinear antenna. Check out the video tutorial below.
YouTube user 907h9879070g9790 has posted a video showing Virtual Radar Server running on a Raspberry Pi with the Raspian hardfloat image OS installed. He used Mono to allow the .NET based Virtual Radar Server to run on the Raspberry Pi. Instructions for using Virtual Radar Server with Mono can be found here.
Combined with an rtl-sdr and dump1090, ADS-B packets can be sent to Virtual Radar Server, and then the aircraft radar map can be viewed on a PC or internet enabled device via a network connection. This can allow a small self contained remote ADS-B monitoring system to be set up.
EDIT: Unfortunately the video owner has taken down the video.
Reddit user BigReid has posted an update on his PCB based hairpin ADS-B filter. He has now added a low noise amplifier (LNA) circuit onto the same PCB board. BigReid used the LNA design written about on this page. The PCB files are here and the Reddit thread can be found here.
YouTube user nerdsville shows a signal reception comparison of his discone antenna and his home made 1090 MHz tuned ADS-B collinear antenna in this video. The collinear antenna shows a dramatic improvement over the discone.
ADS-B is a broadcast system which can be used to track aircraft like a radar. More information about rtl-sdr and ADS-B here.

Update and Note: This plugin appears to be now dead. If you are simply looking for the ADSB# standalone program (not the plugin), it is located in the SDR# install folder from sdrsharp.com.

A user by the name of darkscout.rm on the SDRSharp Yahoo group has posted version 3 of his ADSB# plugin for SDRSharp. The main purpose of this plugin is that it allows the waterfall to viewed at the same time as decoding, which may help with visually tuning the gain settings, or experimenting with ways to block out out of band interference. He has also added in a 1-bit error recovery by brute force option, which is used in dump1090 and may improve decode performance.
ADSB# is a standalone program to receive ADS-B signals and my ADS-B plugin does the same but from within SDR#. Continue reading
Reddit user BigReid has posted on the Reddit rtl-sdr forums his homemade bandpass filter with a pass range of 1-1.2GHz for improving adsb reception. A bandpass filter blocks any interference from signal frequencies outside of the pass range. This might be useful for adsb if you experience a lot of interference from out of band signals at 1090MHz.
His filter is a hairpin filter, which can easily be etched onto a PCB board. You can find the PCB schematic files linked on the post.
