this pcb is correct. this is my best i'm still a beginner

thank you


best time

hello Baterista, new PCB is based on this bulgarin design you attached. all that I see and have to add I added, all improvements, cooper pours (polygons), optimal tracing, etc. I added tantalum caps on bottom side too people could be learn to solder SMD. I especcially do not do a design in SMD because I noticed very small folks may solder SMD components, while I want to make PCB more adaptive and simple for beginners in electronics.

regards

Thanks kt315, this new layout seems very good. I also agree with the "DIP" methodology, for me get SMD components is very difficult.

Mechanical stress is a good reason in favour of through hole design. I also tend to avoid tantalum for it's morally problematic origins - if I can help it.

Hello Kt315, some time I rode the Delta Pulse, based PCB posted by you, very good, working perfectly.
This new PCB has performance improvements over the other?

thank you very much for this new version but where is the pcb file to print.

SORRY the english is NOT my native to write you theoretic deep big text about electronics base. D6B is something hold-and-keep circiut keeping a level zero of D4 output on all 'working circle'. D9D is activated NOT AT THE END OF PULSE TX, but ON THE START OF THE WORKING CIRCLE - PLEASE LEARN THE PULSES' DIAGRAM I DID PUT THOUTHANDS TIMES.

[g.s]

Can you explain Who is ROLE OF( D6B TL062) AND (D9D PIN 6.9,8..)
why activated SWITCH D9D AT THE END OF THE PULSE TX ??
SORRY FOR MY ENGLISH..

yes, some people increases PPS to 300Hz and adds pot auto-manual. then they name it by SNIFFER XR-71 and gladly wildly
told us that they have 'encreased the depth on cola can'. but there IS NOT MODIFICATIONS. THIS IS NOT THE MODS ABSOLIUTELY-!
DP has to work GOOD WITHOUT THE POT and without PPS increasing. if you need in the pot something wrong in your board and find the problem.
