I’ve tried a lot of Raspberry Pi projects and the only one I’ve stuck with is tracking airplanes using ADSB and feeding that data to FlightAware using their PiAware system. The PiAware image for the Pi uses the eth0 MAC address to create a unique ID for the feeder you’re running. The downside with doing this is that if your Raspberry Pi breaks, dies, or if you upgrade to a new one like the Raspberry Pi 3, then PiAware will create a whole new feeder site. So much for your awesome feeder streak! The solution is to spoof your eth0 MAC address on the new Raspberry Pi! I’ve done this method with 3 Raspberry Pi upgrades for PiAware and have a [Read More…]
I had a WordPress site requirement where only logged in users could see the site and it’s contents. I came across this bit of code a few years ago and found it to be helpful. Place it into your functions.php and when a visitor comes along who is not logged in, it’ll redirect them to the wp-login.php page to login. Once logged in, then they can view the site without being blocked. This is an example where it can help keep unwanted visitors away from the content of your site. It’s been working great and I wanted to share it.
Last Updated 2/26/2017 I have an Ambient Weather WS-1200-IP weather station. It’s a great unit and very easy to use and setup! There is an outdoor unit which does temperature, humidity, wind speed, wind direction, rainfall, UV and solar radiation. There’s also an indoor unit which has a barometer sensor. The 2 sensors talk to an ObserverIP unit. This unit plugs directly into your router and has a little webpage that you configure your wunderground.com username with. Once you click save, it instantly starts uploading data to wunderground.com. Couldn’t be easier to start sharing your weather station data! Except. I want that data. I want to archive it on my own system. I want to be able to report off it. The little [Read More…]
If you’re like me, then you have both speakers and headphones. Speakers are the primary of course, but when I want to block out the world, I use the headphones to zone in. I think it’s a little too cumbersome to go into the Sound applet > Playback Devices to change my default sound device every time I want to switch. So with the combination of a few different sources, I’ve come up with a great way to quickly toggle your default sound device. The first step is to get nircmd — this is a free tool from NirSoft. Download and save it to your %windir%\system32 folder. This is typically your c:\windows\system32 folder. The second step is to get AutoHotKey. Download and [Read More…]
Recently, we brought in a new voicemail system at work, and we needed a way to reliably test it. The idea was to have a human call in every 30 minutes and leave a simple “testing 1, 2, 3” voicemail. To me that seemed rather cumbersome for someone to remember to do this every 30 minutes. So I began to think of a way to automate this. That’s when I had the idea for Asterisk to do this for me. To get a fully working Asterisk system up in a short amount of time, and to make it as painless as possible, I started out with the Incredible PBX for CentOS. I was ready to go in about 30 minutes with [Read More…]
