New bench scope - Fnirsi 1014D, 7", 1GSa/s
tunk:
IIRC and if it's like the 1013D, then the 50mV/div is in software
only, in hardware it's 100mV/div (or 1V/div with a 10x probe).

That is correct.
A small downside of the Hantek is that it comes with only one probe. >:D
As many on this forum already stated, it is better to save up our money and buy a Siglent or Rigol scope. Much better scopes for not that much more money.
I have a line up of these cheap scopes and hardly use them. Sometimes the Hantek because it starts quicker than the Rigol, but only for very simple checks on easy to scope signals.
Had fun with the FNIRSI's doing the reverse engineering, so feel I got my moneys worth, but that is it. 8)

But you can't compare these.
Maybe it depends on where you live, but for me a Rigol DHO802 from Batronix would cost me CHF 430 delivered (2Ch, 70Mhz).
I paid CHF 126.70 for the Hantek (2Ch, 100Mhz).
That's not just a little less, it's a completely different price range and decision.
And not everyone always needs the latest, greatest features etc.
The Hantek is enough for me at the moment. Maybe in 5 years I'll buy a Rigol or Siglent. Let's see what's all the rage then.

It seems I can't resist. Looking into making open source firmware for this one.
After working on it for a week or so I can understand why @donwulff gave up on his quest. It involves a lot of work to write up the user interface and connect it to the code I wrote for the 1013D.
For another project I wanted a simple scope user interface and thought "ah well the 1014D is simple enough and will do" so I wrote up some code running on Linux to draw the front panel of the scope and with the information donwulff gathered I hooked the buttons and knobs onto the right commands and coupled the gui with the emulator I wrote for the 1013D development. Nopped the SD card code in the 1014D firmware binary and it is now running on my computer.
This allows me to take screen captures and check it with what I'm generating with my own code that I'm writing for it. Also gives me the ability to trace down into the code and set breakpoints to do further investigation if needed.
It is already taking shape, but far from finished. As per usual there is no consistency in the original firmware on how things are done, so it still requires searching through the code with Ghidra to find the different bitmaps and fonts used to make up the display.
The new emulator is in the hacking repository.
Can't say how long it will take to get it fully up and running, but I will make a new thread on here to keep you all informed on the progress.

I'm looking for testers of the new firmware I'm working on.
