That's a false claim or advertisement. If you see few posts back I've posted this:

Like i said the video shows a different device or you made it wrong somewhere. The LP5 audio is not tick-tick 555 timer like audio but a very pleasant tone audio around 1khz if i remember correct.

The sound can be changed if necessary...This sound has Pulse Star 2 and Pulsar 3,I built this tone on Superdec..

I'm saying this is not an exact copy.
The LP5 has very nice audio and this one on the video has the regular 555 sound that's not that pleasant.
If the sound isn't the same (actually worse) how can you judge what's inside the box?

Yes LP5 has no tick tick the sound gives it a steady tone about 1 khz frequency when there is no metal hear...

Ok friends ,no problem, we have different opinion, im saying
this sound ..




is ...this

teacher does anyone have a good and error free pcb layout?

Jose,
I haven't taken it out yet - it has a dedicated box which needs some work done before I can take it outside for tests.
It has been a cold winter with snow till last week so I left it like that after I finished it couple of months ago.
I may need to finish the box and close it so it's ready to go outside, Spring is arround the corner and the heavy snow is now gone.


In-home tests show on-par performance with the other designs I've tested, which is to be expected ofcourse.
It has better audio than the audio of the other circuits - 100Hz - 1000Hz 50% duty cycle, It's not 13Khz as noted.


It's got alooooot parts so replication costs alot time, efforts and parts.


I'm using my own 2-board design which follows the original board designs (top+bottom) and own schematic so I can't confirm those posted here 100%
nor I can be absolutely sure everything is done correctly by me too, but in deed, it does work.


When I started drawing the schematic it was a soup of noodles as I've taken it out from the board designs.


It was one of the hardest things to do.


Original boards are very complex and their design is not optimal, I think it's done to add a level of sophistication so it's not easy to redraw.


Simple MCU can replace more than 50% of the whole shebang.
I guess it's justifing high price with number of components and all this dipped into good portion of resin.

hello friends
whats this IC name ?

[eclipse]

You can use TL061

thank you very much #eclipse
