Output PC audio to speakers and Bluetooth device

Image
I was searching for a solution to play music in a second room, through a Bluetooth speaker that is connected to my PC...but I wanted to maintain playback through the speaker system directly connected to the PC.  A quick google search brought up a forum that suggested this (donation based) software, VB-Audio VoiceMeter. VB-Audio VoiceMeeter Don't forget to adjust the delay if you need to sync up the two outputs (menu>settings) Don't forget to change windows default audio device to the VB Audio Voicemeter.   Exactly what I was looking for!

Setting up Synology VPN Server on Diskstation 415+, with remote file system access

Image
I am a total noob at this networking stuff. Thanks to Synology Disk Station Management (DSM) GUI it seems fairly reasonable, despite the learning curve. My goals are: to create a VPN that I can access from abroad and use to browse the internet. to create a mapped network drive on a remote laptop that will save backups to the server at home. It all seems fairly straight forward. DSM allows you to install 'packages', such as Proxy Server, VPN Server, Easy-Internet, etc... The first thing I did was create a 'Quickconnect' Account. This allowed me to access the DSM remotely through a browser outside of my LAN. I set up an L2TP/IPSec type VPN in VPN Server package, and after some fiddling with Android, was able to connect while on my WiFi. I figured I needed some DDNS service to log in remotely, but it didn't make sense to have to find a 3rd party service. I then finally found this blog entry:  Secure Public Internet with Synology VPN and Proxy - Travis ...

Car mode in android

I recently started having issues with 'car mode'. The phone will seemingly randomly switch to this mode, which shows a big clock floating on a black screen, and a little steering wheel in the notification bar. It makes all calls go to speaker phone, and activates 'talk back' services. After reading a number of forums I concluded that this error is caused by a faulty mini USB port in the phone. There is apparently some sort of short circuit that makes the phone think it is in a car dock. The solution which seems to have worked fairly well was to clean the USB port with a toothbrush, and compressed air. I also disassembled the phone to tighten the two screws holding the USB board in place. Thanks to this video , my backup plan is to order a replacement USB board for a few bucks, making sure to carefully match revision and batch numbers with my original.

Resurrecting Galaxy s2 gt-i9100

Image
Before yesterday, I was out playing Ingress , and my external battery wasn't working for some reason. My phone died... and when I got home, I plugged it in. When I tried to turn it back on (while charging) I entered a bootloop ('dead battery boot loop'). I tried some quick fixes pursued in various forums to no avail, and soon found myself in CWM recovery mode doing a factory reset. It seems to have been a blessing in disguise...I managed to get CM11.2 working with gapps for android 4.4 kitkat. (Upgrade from my previous version CM10.2…android 4.2). Rescued my two factor authentication, and restored my (practically empty) btc wallet . I love the new privacy manager that allows fine grained control over every app's permissions! Don't want hangouts reading your SMS's?... that's possible now! Another great feature now available allowed you to trigger profile changes based on WiFi connectivity... So for example when you're home, you can disable t...

App to clear .log files for data/log/

Image
This is a solution to a persistent problem on my SII (running CM10.1)... low storage space error. This handy app replaces the procedure in terminal emulator for clearing log files when low storage space warning appears. This error is due to an accumulation of around 1Gb of log files called " dumpstate_ril_RESET_BY_CP_SILENTRESET"  or something like that. This app can be set to automatically clear the logs directory on boot, among other nice features! https://play.google.com/store/apps/details?id=com.liamw.root.logeraser
