I found this old series of videos from OpenTechLab which starts here: [001] Sigrok and Logic Analyzers.
There is more about sigrok over here:

gusmanb’s 24 Channel 100MHz Logic Analyser
In Build – gusmanb’s 24 Channel 100MHz Logic Analyser from Happy Little Diodes I learned about this Logic Analyzer project. I would like to try building one of these for myself one day too.
ZNC
This is a reminder for Future John. Check out ZNC for IRC bouncing: https://wiki.znc.in/ZNC
Learning KiCad
This is on my agenda (but not with priority, I will circle back for this one): Learn KiCad.
Today’s chore
Today I’m going to try and fix this mess.
Electronics reading
I’m reading some stuff, but I’m exhausted, so off to bed, and hopefully finish this reading tomorrow:
Logic Analyzer with 1GHz Sampling Rate
Today I was pleased to discover this: DreamSourceLab DSLogic U3Pro32 USB-Based Logic Analyzer with 1GHz Sampling Rate, 2Gbits Memory, USB 3.0 Interface, 32 Channels.
There are some notes from the manufacturer over here: DSLogic Series USB-based Logic Analyzer.
It’s a logic analyzer which can operate at 1GHz that’s within my price range. I’m not rushing off to buy this thing, but it is certainly on my list.
The only other thing I have seen that compares to this logic analyzer is this RIGOL DS70304/DS70504– Digital Oscilloscope 3GHz/5GHz 4 Channel 20GSa/s 2Gpts 1000000 wfms/s which is roughly two orders of magnitude more expensive.
6 Horribly Common PCB Design Mistakes and AppCAD
Today I enjoyed watching 6 Horribly Common PCB Design Mistakes and the follow-up video Design Mistakes You Must Avoid on Your New Electronic Product.
In the first video I learned about AppCAD Design Assistant which is a free tool which boasts a broad bunch of features (and, particularly, it can help you design an antenna on your PCB):
- S-Parameter Analysis and Plotting
- Active Circuit Bias Design
- Cascade Noise and IP3 Analysis
- Transmission Line Analysis
- Signals and Systems
- Complex Math Engineering Calculator
I haven’t used AppCAD yet, but I will check it out soon.
Gonna try ‘restic’ instead of ‘borg’
QUIC Loss Detection and Congestion Control
This came up in my feed today: QUIC Loss Detection and Congestion Control. I wish I had time to read it closely! It’s about how they re-implement the TCP bits and pieces (such as congestion control) atop UDP.
