If something is not clear - ask.

 Great, thanks buddy!
 That will help a lot.

 Have you heard of Scopefun? http://www.scopefun.com/
 It's a Open Source Oscilloscope with very intersting specs:
  • 100 Mhz Real-Time Sampling rate / 3.2 Ghz Equivalent-Time Sampling rate
    2 analog oscilloscope channels (10-bit)
    2 analog generators (12-bit)
    16 digital channels (logic analyzer / pattern generator)
    USB 2.0 interface

 It looks like they're in the early stages of hardware yet, but it promises.  :D
  There is a PCB V1.2 at OSH Park. https://oshpark.com/shared_projects/ybnpFXLE

 My second solder test: :) (The first one got bad)

Today I tested a new current stabilization system (purple circuit board).
The sun at the zenith, it is clear, the sensors are under direct rays (the "target" stands facing the sun).
IR diodes are narrowly focused (not 6100), the case is the same "Predators" (AK12).

Immediately exposed 100% of the IR power.
Well, what can I say ...
I'm in a pleasant shock! :)
Judging by the map - about 200 m.
Let me remind you - the bright sun and direct rays on the sensors.
And powered by one lithium can, without voltage converters.
I'm satisfied with the result.


Why can not I explain this difference, all my theories do not work.
Can it be banal IR diode is better exposed (adjusted)?
Can constructive "vices" of the old scheme.


In this case, if you set the IR radiation power 3%, then there are no reflections from the walls, and you have to aim at a separate sensor. Immediately two sensors can not be hit.
To "fix" the result I plan to make even "purple" boards and put in the second "Predator" and again to test.

Thanks again comrade duaneb!
If not for his printed circuit boards, all this would be dragged on for months ...
And now we have a working hardware - can publish the hardware release .

 Pingvin, I am soldering the PCBs and I am having some difficulty knowing the correct place of the components on the PCB...
 Do you still have the V3 PCB files? The white PCB. I'm using de V2 diptrace file, but some components are on diferents places.
 Thanks again.

Has corrected.
I hope I did not miss anything.
If something is unclear - ask, do not be shy.

 Working hard here, I know there are some questions to answer you... I will.
 
 But, one more question for you... How to install bootloader and code in STM? Onboard USB or I'll need a programmer?

The loader is a separate program.
It can be downloaded in two ways:
1. Using the SWD connector and the ST-Link programmer (or its clone). ST-Link also allows debugging programs directly in the controller.
2. Using the UART connector. If there is a COM port on the computer, you will need an adapter RS232 <-> UART, for example, on the MAX3232 chip. If there is no COM port, you can use the USB <-> UART adapter .


After the loader is swirled into the controller, the firmware can be changed via the onboard USB connector.

 Ohhh, I used a lot MAX232 when I worked with LED Panels in 2000.
 
 Please, help me again...
  Is the component with Red arrow wrong?
 Now I saw the schemme, and see many Caps with polarity. In this case, ceramic Caps are wrong, isn't it?
 In the Blue Arrow is ceramic Caps?
 
 Uow... it's hard...
 Thanks.

If this ceramic capacitor is 10 uF (or more), then it's ok.
Let it remain, this is a filter for the supply voltage.


In the Blue Arrow is ceramic Caps?

Yes - 0.1 uF

Uow... it's hard...

Therefore, I am ready to start production of fully assembled devices.
And that the cost was democratic.
That the person had a choice - to be assembled by yourself or buy a ready-made device.
I do not know - can we discuss such issues here?


P.S. And for me, soldering is already like meditation - I even enjoy it. 
Now I understand women who embroider with a bisser.;) :D

P.P.S. I am confused by the USB connector on your photo.
What kind of connector is it like the location of the contacts?

Guys, what about these radio modules?
SI4432

https://ru.aliexpress.com/item/SI4432-wireless-module-1000meters-long-distance-240-960mhz-Special-promotions/929600736.html?spm=2114.13010608.0.0.6FVMur
I think they are better suited for our purposes than NRF24.

  I'm reading about the radio modules too, as well as the mesh network implementation.
 Getting a live score will be a huge step forward.  :D

Mesh network is difficult.
To realize real-time statistics viewing, we can do without mesh networks.

There is an alternative to radio modules - the use of smartphones.

I think we need to develop both directions.
