Pulse Star II (first analog version)

[Orbit]

This is not a reason for the device not to work! The scheme is not in order because it was important to me that it works for me, that's why there is also a comment in Serbian regarding the voltage, the rest is perfectly fine.

[Orbit]

I don't have a lot of time and I completely neglected the old 2 pulse, but anyone can rearrange the symbols on the diagram regarding the voltage, everything else is the same as on the pcb! With pcb, the symbols gnd + bat - etc can be properly marked!

[Orbit]

Otherwise it is true that there are two jumpers in the epoxy resin! So it happens that the device when we put all the original components back on the pcb records without the included coil! With the coil on it works normally! The only thing that can be noticed is that the battery indicator needle shows that the battery is not fully charged even though it is full. So I made a scheme to avoid those problems! I intended to solve the problem with the short circuit in a while when I have more time.

So these two jumpers are not drawn in the schematic, which means the schematic is not complete and has flaws.

DISC board is filled by epoxy and that why it is invisible. the pcb is above on a photo and you have to see mark DISC PCB on it.

Jumpers are often required for 2-sided PCBs and usually are not included in the schematic. This is normal.

Repeating over and over that the schematic or PCB has errors is not going to solve your problem. Multiple people have said it works, so it's time to try a different path. Troubleshoot your circuit and figure out what is wrong with it. Start with the power supplies, then the timing, then the TX, then work your way down the RX. It will probably help to redraw the schematic in a more readable form.

Yes, that's right, I have to find the problem myself.

The resistor values in the schematic are wrong and some of the wiring is incorrect.

Yes, you've said that many time, no need to keep repeating. It is now up to you to find the problems.

I know very well what I'm talking about, two original pcbs, I disassembled all the components, resistors, capacitors, and everything else is correct! The fact that someone does not know how to add 2+2 = 4 is already his problem!

You simply cannot arrange something, buy it and not think! No one can help you if you're stubborn, you haven't broken a single pcb and you know it's not true, at least ten people have done the device, maybe even more, all of them work except for one person?!

[Orbit]

It seems to me that the translator translates rather poorly?

Those who made it changed the resistor values and changed some of the paths to make it work.

Which capacitor did you remove, I think you mean the 1.2n capacitor that is used for the 555 IC?
