The opensource Sigrok analysis suite has support for the ZEROPLUS Logic Cube. Might be worth touching on when you make the Logic Cube video.

[AJMansfield]

You should totally do a thing where you probe the logic analyzer with itself, if for no other reason than the sheer absurdity of it.

How could you miss the "Logic Analyzor" at 11:44 ?

[TarzanAndConz]

I've been using this software for years. It's much better than those christmas tree programs you get with other analyzers. It looks 10 year old but it does the job perfectly.

One time I watched Techmoan use his Soundcard and Audacity as a logic analyzer for some old hardware or a tape. I don't think Techmoan ever realized he was using a logic analyzer but it worked and he was able to read data.

That's a good lesson there because if your projects are retro computers or something slow like that a 44kbits sample rate is good enough and most PCs can do it and it's not even expensive to get soundcards with higher sample rates.

Not sure if you still have this unit (LAP-F1-64) but they did take the comments on the software and have updated the software. Not sure if its any better functionally but it does look a bit better visually, might be worth a follow up 2min review in a future video.

When I see "Logic analysers", I imagine a couple of Vulcans looking at things and saying "Logical" or "Illogical" in response to

[Graham_Wideman]

Dave asserts that the software is "only for up to Windows 2007" and proceeds to comment on this meaning the software is from 2007. Actually the product spec says for Windows 7 (there was no Win 2007). Win 7 was released in 2009 and Win 8 came along in Fall 2012. Fair enough criticizing the software for lack of sophistication or broken or lacking features, but the date criticism is a bit off.

I find it quite interesting that so many people that watch his videos don't know what a logic analyzer is or how it's used.

[jeffmurri]

The software I downloaded for the Logic Analyzer that comes with the Arduino Starter Kit is very polished. I like it a lot. I also can't recommend the Arduino Starter Kit with Logic Analyzer enough. It is a bit spendy at first look, but the manual is superb and the parts are quality.

[SidneyCritic]

Not a fan of the fumbling around and not reading the manual. Too many wrong conclusions due to not knowing the software well enough. It's like that KiCad video where I had 3 hours watching tutorials and knew 10x more than was revealed fumbling around wrongly. Classic case of thinking all software uses a standard way to do the same thing, like MS uses std buttons in most of it's stuff.

[Tommyinoz]

That's awesome, I can charge 32 iPhones at the same time.

I have a ZeroPlus cube. Bought first year in college, before 'bus blaster' was a thing. It's really useful for debugging. The analysis software was expensive. Like $50 for each protocol. I've written a review and gotten 10 protocols for free. It's great they are all free now.

Terminal G of the plug in adaptor at 12:24 looks like it has a bad solder joint?

[soothcoder]

Would have been cool to see if it could run as fast as it claimed. I wonder what the signal integrity is like when running full-tilt

[flitjes]

Totally agree on the GUI interface for the ZeroPlus Logic Analyser. This is the main reason why I replaced it for a Saleae

IEE1284 Centronics parallel printer to USB? Why? 9:41

[theantipope]

About the mystery comparator: My bet is that it's a sneaky hack where they're dicking with the VCC voltage for the HC245 buffers to use them as comparators.

Nothing says quality like Serif fonts on a PCB.
