Cool display for my VDR project


Because this blog is new, I am adding recent stuff I got and made, so things are a bit out of order... Sorry for that - I should have started this blog much earlier.



Here is a cool add-on for my VDR project: a display. This particular one has support under Linux and some interesting features. It comes with an IR-receiver and a remote control. On the board there is a relay that you can connect between the power button of your case. It allows you to switch the PC on and off with the remote, thus making it behave just like any othe receiver.

Check it out here.

VDR Project


Been working on my VDR project.

I am using the awesome yaVDR distribution. It features both VDR and XBMC out of the box!

More info's about it:

VDR Homepage
VDR Portal featuring forum's for all known VDR distributions

Current issues to be fixed:

- S3 Suspend to RAM (nvidia wake-up does not work properly)
- Channel scan (functionality not satisfactory to me)
- Channel scan does not find some DVB-S2 transponders on Hispasat
- DiSEqC configuration through OSD (functionality not available)
- LCD not supported by XBMC

Satlook Digital NIT Color


Thanks to a good friend, I got to exchange my Satlook Digital NIT with a Satlook Digital NIT Color.

Seems just a few extra letters in the name, but makes a huge difference: this field meter now displays both analog and digital DVB-S channels on its huge TFT screen in color!

Definitly a great device for SAT-DX and professional dish installation.

Window Lite Plus by ComSonics, Inc.

Seems I just won this device at eBay...

Let's see how it turns out. Known flaw: broken battery. It is a custom battery, so I'm not sure if I will manage to replace/repair it.

Let's see...

This is a full spec handheld CATV field meter.
