Taking pictures and geeking out over cameras was one of my first hobbies starting with an old Olympus point and shoot, I then moved up to a DSLR upgrading as new and exciting technology became accessible to my summer job budget. I then got the opportunity to buy a Leica M8 and was immediately hooked… Continue reading Pieca: A Raspberry Pi Camera System for Leica M Mount Lenses
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
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
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
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
I previously create a PCB patch antenna using the Matlab antenna design toolbox and had some pretty good results, but the narrow bandwidth of patch designs means that small errors in the simulation parameters cause a shift away from your desired frequency. My old post into the details of my journey of learning about patch… Continue reading 2.4GHz PCB Patch Antenna V2 Design with Matlab
The Ambasat-1 is an open-source Sprite Class Satalite that you can assemble, program, and have launched into space! Your very own satellite in space! When most people hear the word satellite they think of multi-million dollar devices that are way out of the reach of your average maker. But the cost of satellites and their… Continue reading Getting Started with the Ambasat-1
I was getting pretty fed up with my Macbook Air 2011 webcam now that we are on a constant stream of Zoom video conferences and calls. And with the shortage of nicer webcams in stock I started to look into weather it was possible to use my older DSLR camera as a makeshift webcam. I… Continue reading Mac DSLR Webcam
Diving deeper into antenna design you find really interesting antenna structures based on what parameter you are trying to optimize for. I was looking for antennas that had wide bandwidth and some directionality, to use in conjuncture with my LimeSDR Mini for one of my many projects, that's how I found out about the Vivaldi… Continue reading Vivaldi Antenna Design with MATLAB
