Quite a while ago I tried the HF Mod (aka Direct Sampling Mod) on one of my dongles. The simplest way of doing it is by connecting one of the RTL2832U’s ADC (pin 1 or 2) inputs to an antenna which is exactly how I started. Shortly after that mikikg told me about using a …
Recently one of the four drives in my HTPC kept dropping out, first it happened once every few days, then after several hours. The weird thing was that it always came back after losing the SATA link and allowed me to mount it again. I first thought it was a problem of the SATA controller …

TNT stands for Thumb2 Newlib Toolchain, a GCC/Newlib based toolchain project I started quite a while ago. Trying various other toolchains like CodeSourcery, summon-arm-toolchain and YAGARTO, I realized none of them really seemed to have the smallest ARM Cortex-M microcontrollers in mind; They were wasteful with RAM as well as flash memory. TNT has been …
A while ago I already managed to compile gqrx on OSX, but then Alexandru Csete decided to move on to a new audio backend called pulseaudio. Sadly there is no proper pulseaudio port for OSX. Thus I bring you my branch of gqrx 2.1 which runs quite well on OSX. It contains all the rtl-sdr, …

Qt has a great tool for building self contained application bundles on OSX, it’s called “macdeployqt”. Though I recently had a really weird bug while using it. When I ran the application normally everything was fine, but once I used the macdeployqt all the icons were missing. After a while investigating this I realized not …

Due to my recent acquisition of an RTL-SDR compatible radio module (Some would call it DVB-T stick) I started playing with radio transmissions. Doing so I found POCSAG transmissions which I tried to decode using multimon. Sadly multimon was very broken, after I finally managed to compile it on OS X I realized it had …
I’ve recently added some modifications to the Cyanogenmod kernel. They include overclocking up to 2ghz as well as lower idle voltages (undervolting) and a higher default maximum frequency. The maximum frequency after bootup is now 1516800hz. It can be changed up to 2016000hz. Frequencies higher than 1612800hz are unstable when using the ondemand governor on …

I lately had some problems changing my laptops (A Samsung Q45) brightness since the major distributions went on and started using KMS instead of the prior Xorg driver, even though most Samsung laptops aren’t properly supported. Searching around the net I found some hints about using setpci – Writing directly into the hardware. dekar@vasectomy:~$ sudo …

I didn’t find any information about this (just people whining about not getting a firmware update) so I feel like posting it so others may find it using google. My HD700X seems to be able to do 120hz. I just did a quick test using my laptop (vga) since my media pc (hdmi) is broken …

I’ve added the link to the source quite a while ago, but I feel like posting it here as well so php beginners who want to play with Imagemagik can find it, my banner generator is Public Domain now. So you can get it and do whatever you like using it – just don’t blame …
