Okay, I'm not really much of a 'hacker' in the sense that most people think of. I don't break into things, crack passwords, etc. However, I do like to tinker. Recently, my co-workers and I decided to purchase and try out these handy new "smart" power cords: the IPLC M4 …
Component Level Board Repair
I had a fun day at work today. Often my work revolves around cleaning and paperwork, with the usual computer issues that need reset or rebooted to be resolved. Occasionally there will be a more complex computer issue with the virtual machine host, or raid arrays if I'm lucky. Today …
FreeData
FreeData is "a free, open-source, multi-platform application for sending files and messages, using the codec2 HF modems." [1]
Of course, I'm an amateur radio operator, also know as a ham. And, if you read this blog at all, you know I'm pretty into Linux and open-source software. So, it should …
Arduino TNC - Part 2: Software
Hopefully you read the last article I posted about building an Arduino TNC to perform packet email (Winlink) with my Android cellphone and Baofeng handheld radio. If not, I recommend that you check it out so that this post will make more sense.
After completing the hardware section of the …
Arduino TNC - Part 1: Hardware
Recently, I decided that I would put some of these great components that I have lying around to work. I've been doing a lot of Winlink lately, and messing around with my dilapidated Baofeng UV5R. So, I decided to intertwine the two projects. I decided to build an Arduino TNC …
Did Hans Niemann Cheat?
A slightly different post today, and certainly not my usual style. Opinion pieces are not usually my thing, but today I played a chess game that made me stop and think about the current chess scene allegations.
Above is a game of chess that I …
3D Printing a new Baofeng UV5R battery holder
In previous posts, I "fixed" my UV5R which had a bad battery by soldering on a connection by soldering on a power connector for a standard 9 volt battery. In those photos, you could see that I just taped the battery to the back of the case and used the …
Winlink on Android and a signalink USB device
Recently I was looking for alternatives to allow me to send Winlink messages over the 2m band via packet. One of the problems that I can't seem to solve on Linux is making AX.25 and Direwolf work properly. I've read through (and followed) a dozen tutorials, but no matter …
Baofeng UV-5R Battery Fix
This Baofeng UV-5R was the first radio I ever purchased after getting my license. Actually, it was just plain the first ham related radio I ever purchased. But, it didn't last long, within a year the unit quit working. I realized that it just needed a new rechargeable battery, but …
OwonOszi on Linux
Last post I wrote about trying to use my Owon handheld oscilloscope (HDS242) with Linux. I had tried several options, and among them was one called OwonOszi. At the time, I didn't build it because it was written in pascal. I've never worked with pascal before, and was mistaken to …
