Hi Alec,,Thanks for the final video. Another successful and well documented build! Regards, Marty
Hi Marty,
If all goes well I hope to put out a short video showing the pre-amp output with a new op-amp. Maybe Friday.
Great work. Congrat !
Thank you for watching Mario. I enjoyed this project.
Hi Alec,,,Sounds great! Hopefully the results wll be as good as you expected them to be! Roll on Friday!,,Regards, Marty.
Fingers crossed.
Can you make some videos of your builds in use? Even some air tests would be great!
I have a few videos where I am using the Mini Pulse Plus. They are on my channel.
I cant build this since i dont have an oscilloscope but good luck towards your build!
If you are able to, perhaps you could try building a kit oscilloscope. Something to consider. I did one for fun on my channel, there is a video.
Hi Alec, How do I order PCB with other relevant documents to Build the project , Quite appreciable work
The Gerber files and all information are available on the Geotech Forum. I do not sell anything, I only created the build videos.
Thank you for watching.
@@SurfDetector I am sorry can't find the files of Crossbow Classic. Would it be possible to provide the link
@@prabirdebnath5197 I'm sorry I do not have time to search for the thread. They are there, you need to search.
Hi.. i got the PCB from a friend but now iam looking for the schematic. Any idea where i get the schematic?
It's available on the Geotech Forum
Can i replace a ne5534 with a ne5532 for a surf pi also can i subsitute MPSA13 by a bc 557?
5532 is a dual op-amp versus single for 5534
mpsa13 is npn versus pnp for bc557
Always compare data sheets. So the answer is no for both.
@@SurfDetector I mis typed for the transistor. I wanted to know about bc517. It's a npn , will it work because getting mpsa13 is impossible for me.

This can be useful if you are unfamiliar with parts. As I said previously, you must compare data sheets.
@@SurfDetector Thanks for the link
