In my quest to become more familiar with Docker I decided to create a container to run another wireless radio software called Kismet. Kismet is a wireless network and device detector, sniffer, wardriving tool, and WIDS (wireless intrusion detection) framework. Kismet works with Wi-Fi interfaces, Bluetooth interfaces, some SDR (software defined radio) hardware like the… Continue reading Creating a WiFi Monitor with a Kismet Docker Container

Quick and Dirty ATTiny85 LiPO Battery Gauge
Portable projects require some kind of battery, but getting information on the voltage level or how much battery life you have left is a whole other problem. This can be solved by monitoring the voltage on the battery using an analog to digital converter, and then some firmware to read that digital value and produce… Continue reading Quick and Dirty ATTiny85 LiPO Battery Gauge
Simple GNURadio Server Setup with noVNC Docker
I have been using GNURadio since college, and even now just getting the software installed and working with your hardware radio can be a challenge. So I decided to create a Docker image that not only has GNURadio installed but can be accessed via VNC in a browser tab. This allows this container to be… Continue reading Simple GNURadio Server Setup with noVNC Docker
Analog Experience: Shooting Film With The Leica M4
Shooting film has always interested me. I started out using my mom’s Pentax ME Super as well as a Leica iiic that I had picked up off of eBay for $250 with a 50mm collapsible Elmar lens. Coincidentally still my only true Leica lens. But I always wanted a film Leica M camera but as… Continue reading Analog Experience: Shooting Film With The Leica M4
Easy WireGuard Setup on Unraid
I have been wanting to configure my own VPN for some time now in order to access my shared drives and machines on my local network while traveling now that my main computing machine is a desktop. I had looked up several tutorials but wanted something that was super quick and not too networking heavy.… Continue reading Easy WireGuard Setup on Unraid
First Look at CENOS Antenna Design Software
Hobbyist and low-cost antenna design software have been usually limited to basic theoretical calculations based on ideal EM equations that could be done on the back of the hand. It is only recently that full EM simulation has drifted down to the masses in a semi-affordable way. CENOS Antenna Design software is one of the… Continue reading First Look at CENOS Antenna Design Software
Emulating Kodak Aerochrome Infrared Film with Python Image Processing
What is Aerochrome film? It is an analog film stock that is sensitive to infrared light and uses false-color reversal to express infrared light as a visible color. Infrared (IR) light is invisible to the human eye but is all around us and be felt as heat. All objects in the universe emit some level… Continue reading Emulating Kodak Aerochrome Infrared Film with Python Image Processing
Measuring the Range of nRF24L01 Modules with CircuitPython
I became really interested in the capabilities of the nRF24L01 radio modules due to their insanely low price ~$2 in quantity, compared to something like a LoRa module ~$25. So you can basically have 10 for the price of one. Now I am not saying these are comparable devices, since the LoRa devices can be… Continue reading Measuring the Range of nRF24L01 Modules with CircuitPython
Improving the Eureka Mignon Grinder with 3D Printed Accessories
Since I started working from home I have been thankful to have a Breville espresso machine that has kept me caffeinated through tough problems and tight deadlines. This machine is a combo espresso machine and grinder. This is nice because it's compact but does come with some tradeoffs mainly on the grinder side. It only… Continue reading Improving the Eureka Mignon Grinder with 3D Printed Accessories
LiteX on the SQRL Acorn FPGA
The SQRL Acorn is an M.2 form factor FPGA accelerator card originally designed for cryptocurrency mining acceleration. But due to poor performance and little support, it failed, causing a big scandal. Fortunately for us that know how to use FPGAs, we can re-purpose the hardware to do other kinds of acceleration, such as DSP processing.… Continue reading LiteX on the SQRL Acorn FPGA
