Now with last year's hot technology!
This is a follow up to this post and this video, about my LHCP L-band feed made from laser-cut wood. I gave away a few of these at Open Sauce 2026, so I figured I’d make a new video about it as well as post the text instructions.
Secretcon (the Cybersecurity or “Hacking” conference) returned to the Twin Cities, this time in St. Paul. I gave another talk about satellite stuff. I also had a lot of fun at the conference, there were a bunch of great presentations, fantastic hubs and exhibits, and lots of fun interactive IT security things to do! For […]
Similar to some of my past projects with the Tailgater and Carryout antennas, I’ve written a new Python script for the Discovery Drive. This lets it act as a radio telescope / microwave imager. So far it’s mostly useful for strong satellite signals, but it’s a stepping-stone to some larger projects with the bigger dish […]
I am frequently asked where to find used satellite dishes for SDR and radio experiments. In the US I usually direct people to Facebook marketplace, Craigslist, or your local state/city/university surplus department. For other countries, R1chae has been putting together a list of possible sources and asked if I could post it here. R1chae’s list […]
While I can’t afford to send a cubesat into orbit, I can (sort of) simulate space in my garage! I picked up a vacuum chamber from Ax-Man Surplus and got ahold of a free vacuum pump from a friend’s company discard pile. I can only get it to go down to about 1/20th of an […]
I’ve been poking around at my Winegard Trav’ler antennas a bit and have some additional info beyond what’s on my Github and prior posts. I’ll post some of it here (this was originally on my Discord). These are the “regular size” satellite TV dishes found on RVs that have a motorized turret to point them, […]
I’ve been making progress on the radio observatory / satellite tracking station at Sandland. We picked this 18ft geodesic radome up a couple years ago from the Carp Observatory and have been slowly getting it put together. During 2025 I poured a cement footing and installed a satellite dish and motorized pointing system. This is […]
I generally avoid overt politics on my website and YouTube channel. But I feel that the current situation in the United States has gone beyond politics. I’m aware that many won’t like what I have to say, and may stop reading right here. They might unfollow or unsubscribe. They might try to cancel or otherwise […]
Technically it’s a cubesat “simulator”, but it’s the first really affordable one I’ve seen! Only $130 for the base model (I also bought a radio add-on, and I think they sent me some extra parts). You can find these at https://www.mysatkit.com/
Here’s my quick overview video of Secretcon 2025: And you can find the full video of my talk here:
