Configure IC-7300 with HRD and SDRuno as a panadapater
I have an MFJ-1788 Mag Loop antenna. I can tune it very easily by using my RSPdx to view the waveform. In the picture attached you’ll notice that the antenna is tuned a little bit high for my current frequency. This makes it super easy to tune without worrying about having to put signal outContinue reading “Configure IC-7300 with HRD and SDRuno as a panadapater”
The creativity of 3D printing One of the things I love about 3D printing is the creativity of it. I didn’t want to print any supports, so by putting a flat spot on one side I could print it with no cleanup needed.
3D printed adapter
Needed and adapter to connect my vacuum to my belt sander. Tada.
Fixed the CNC mill…again
One the disappointing aspects of doing your own CNC conversion is that you are the manufacturer. Need to know the limits of your machine? Go ahead and start running tests until something breaks. Rinse and repeat.
Black and Decker Portable AC
I recently picked up a Black and Decker Portable AC https://www.amazon.com/Black-Decker-Portable-Conditioner-Display/dp/B01DLPUWG2 and wanted to port over a Blynk project I had created. I couldn’t find anything online about what the infrared protocol is for the remote.

Nuclear cooling towers or tank stands
These tanks are awfully tippy when connected to a Little Torch. Not so much anymore.
TDR with the NanoVNA
The performance of my satellite downlink station is nowhere near as good as I would like. I been doing some various troubleshooting measures to try and figure out what is going on. In my previous post, you can see some of my explorations about antenna tuning. In this post I took my first pass atContinue reading “TDR with the NanoVNA”
I cut it twice and it’s still too short!
For my satellite ground station I built an antenna from the plans by WA5VJB http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf I originally built a 7 element 70cm antenna. But then added on a two element 2m one. While I had tuned the 70cm antenna, it was tuned a little too low after the second cut to shorten the driven element.Continue reading “I cut it twice and it’s still too short!”
abandoning Pi-Hole for cloudflared
I’ve been using Pi-Hole for a while and it just caused too many problems. Many shopping carts across the web would just fail. I need to run google ad campaigns and you can’t get to the admin UI. Therefore I decided to move dns resolving back to my ER-X and instead use cloudflared to resolveContinue reading “abandoning Pi-Hole for cloudflared”
Satellite Fun
I’ve been slowly working towards building a satellite uplink and downlink station for years. I have finally reached a point where I finished building the station and have Receive some signals. The performance is rather abysmal, I still have a fair amount of work to do.
Wrench Holder
Seattle is due for a big earthquake. Our wrench for our water barrel and emergency gas cutoff was always going walkabout. I whipped up this little holder so it has a home to live on the back of our front door.
Causal Inference Resources
I was inspired by the post “Why you should stop worrying about deep learning and deepen your understanding of causality instead” to write up some of the resources I’ve used over the past year as I myself have tried to learn more about causality. The field of Causal Inference has become much more rich andContinue reading “Causal Inference Resources”
