Ski Helmet FRS Headset/Microphone Setup

I have a busted XBOX headset (that the dog chewed up so there is no foam)

I have a ski helmet. 

I have a FRS radio.   Here is how to combine all of them....

When I took apart the XBOX headset, I noticed that the Blue and Black wires were wired to the speaker, and the white and ground (no rubber) were wired to the microphone, and this was all wrapped up in a 2.5mm jack.  I tested this set up with a FRS radio that had a 2.5mm jack, and the microphone worked, but the speaker didn't.   Not sure why it didn't work, but I figured I could make it work, so I snipped all the connections.  

I wanted to put a new plug on the headset so that I could use it for a radio as well as an iPod to have the option to listen to either music, or plug it into a set of FRS radios I have with a 3.5mm jack.   I had a spare phone headset that was also broken, so I cut the headset off of this, and I was in business.  This had red, black, and ground (no rubber) wires coming from it. 

So I wired it up like so:  

Which is to say, I took the microphone ground, and the ground to the 3.5mm jack, and tied them together and soldered them to the headset.  Then I soldered the black wire from the jack to the headset, and the white wire from the microphone (you can't see it in the picture, but it and a ground come out of the black wire from the microphone boom in the top hole) to the red wire of the jack (and applied a little heat-shrink tubing to keep it all sealed). 

Then, I cut off the part going around your head, leaving just the circular speaker and boom.   I opened up the stitching on my helmet earpiece, and slipped in the device, creating a hole for the boom, and a hole (hidden by a strap) for the cord.    Here is what the final result looks like:

I must say that it looks pretty clean, like I bought it instead of building it from broken pieces I had laying around. 

Now, if I want to listen to music on my iPod or iPhone, I can simply plug either into my helmet.  And, if I want to communicate with anyone on FRS radios or the iPhone, I can do that equally as well!   I can't wait to get on the slopes to try it out!!!

atftpd vs tftpd-hpa

Recently I was trying to tftp files from a Windows computer to a Kali box.   One version of Windows worked, but another didn't.    After much troubleshooting, here were my symptoms:

I could tftp a file from-to any Kali box from-to another Kali box
I could NOT tftp files to a specific Windows 7 box from any Kali box
I could NOT tftp files to a Chrooted-Ubuntu-Chromebook box from a Kali box

After MUCH troubleshooting, going through every setting in atftpd, it seemed like it literally was a client OS problem.  Different clients simply would not download files---unacceptable.

Thus, I switched to tftpd-hpa.   To install:
apt-get install tftpd-hpa

files go to/come from /srv/tftp, but it needs to be a tftp user. Thus, I needed to:
chroot -R /srv/tftp

Also, if you want to be able to put files ON the tftp server (from a client), you need to modify /etc/default/tftpd-hpa:
change "TFTP_OPTIONS="--secure" to "TFTP_OPTIONS="--secure --create"

I also changed the IP li…

ADS-B plotting with Kali (and other SDR goodies)

Recently I wanted to try some Software Defined Radio stuff.   
I had a RTL-SDR, FM+DAB, DVB-T USB Stick Set with RTL2832U & R820T. that I got from:
But, even though this dongle would break out FM radio stations, and ATC frequencies (like the local Ground Control, tower, and even ATIS), which was cool, it wouldn't break out ADS-B.   
Thus, I bought a Vantech Green Mini RTL2832U R820T DVB-T SDR DAB FM USB DIGITAL TV Tuner Receiver RTL-SDR Project + DAB dongle Tuner MCX Input from Amazon, and tried this.  
This dongle was able to listen to the 1090MHz frequency required for ADS-B (as it goes from 25MHz to 1700MHz).  There were tons of Windows programs out there for breaking out and plotting ADS-B Mode S broadcasts, but not many for Linux.  
For Kali Linux, here's how I got it running and plotting planes around my home:

Temper Temperature monitor on a Beaglebone Black

Beaglebone Black as a temperature monitor:

Recently I wanted to monitor the temperature of my shed.  I thought I'd use a small computer such as a Raspberry Pi or a Beaglebone or Odroid.

My Raspberry Pi boxes were all in use, so I grabbed my Beaglebone, which was doing nothing.

I flashed it with the Debian9.32018-03-054GB SDIoTimage, but that seemed like it was running lots of bloatware and the ethernet interface wouldn't take a static IP with /etc/network/interfaces.

So I went with the Debian9.32018-01-284GB SDLXQTi image instead.  I still had the same problem, that lots of junk was running, and I couldn't configure my interface by modifying /etc/network/interfaces

So my first step was to get rid of all the bloatware.  If you're using a Raspberry Pi or something, you can skip this and just go to the second step below

STEP 1--Remove Blotatware from Beaglebone Black:
