Working on TARPN network

TARPN Terrestrial Amateur Radio Packet Network

The group is setting up two TARPN nodes, using Raspberry Pi 3, NinoTNC, old radios used in buses, antenna, power supply etc. The two nodes will talk with each other at a short distance using UHF frequency. Once complete, another node will be built for the mixxer with a stronger signal and antenna mounted on building and eventually we will connect across the NC hopping from one node to the next.

OctoPrint Case for 3D

I finally got around found a case for my raspberry pi 4 running OctoPrint and controlling my 3d printer remotely. Plus check the status of the print and watch video of the 3d Print progress. My biggest issue was determining a way to attach to the printer itself. For past six months, its be just setting on the side. My first thought was to drill holes to frame and screw on case. However, I determine the easiest and most solid way would be to use ties.


Setting up SDR-RTL on Raspberry Pi 4 was quite easy.

  1. Installed CubicSDR
  2. Attach SDR-RTL USB device to RPi4
  3. Start with menu at Other>>CubicSDR or from terminal CubicSDR

I had a little trouble with getting the sound thru the speakers. Basically on the CubicSDR, the audio being routed to HDMI verse Analog.

Also note, that I tried running on RPi3 and had mixed results. Sometimes it worked and other times it didn’t. It’s CPU intensive and think the RPi3 just doesnt have enough power.

Kismet running on NetHunter

Kismet can be found running WarDriving up under Nethunter app, however it also needs an external wifi adapter to run well. Attaching a USBadapter dongle, I was able to use the ALFA AWUS036ACS. From a command prompt


apt-get install firmware-atheros # this not be required

ifconfig wlan1 up

ip link set wlan1 up

airmon-ng start wlan1

airodump-ng wlan1mon

Then started wardriving, open browser and started resource.
