Hattusa Pulse

I don't have any concerns for the project, the important thing is to find time and finalize it. I did not receive the e-mail you said you sent me.

Please check the personal information in the upper left corner of the webpage. Personally, I think the operational amplifier power noise is a big problem that needs to be dealt with in the sensitivity of the detector. Perhaps its noise has far exceeded the accuracy of 16bit, almost all detectors are

When the MCU acquisition lf398 voltage signal, we should do some processing to this signal, in order to make it more stable

The lf398 output is stable enough, I'm out of town right now. I won't be able to go home until next Saturday. I will continue the project when I return.
What kind of interface do you suggest I design for android, what should be on the screen?

I am not able to shoot video. I took these two videos in a hurry. detector is ok. There were 1-2 errors on the PCB board. In addition, 3 buttons were insufficient. I added 1 more button. I don't like the 16x2 screen. because it took me a long time to create a menu in the software.
features;
a- The detector works with metal separation.
b- There is a threshold setting. working
c- There is a sensitivity setting. working
The d-bluetooth feature has not been activated yet. only when android apk is prepared it will work in that part

note:
I need to fix the errors on the PCB. What kind of features should the detector have during correction?

[Hattusa]

it seems that there is no one interested in the detector, there is no suggestion from anyone, there is no one to make this detector. Finally, I will remove the 16x2 LCD screen, buttons and sound part from this detector and make it as a device that only works with android apk and share it here. I drew the PCB board, now I will line up and run this board. When I share it here, if there is still no interest, I will sell it as a project.

Share the apk brother

Share the apk brother

I haven't written the apk yet, but I will as soon as possible, I didn't write the arduino code either. I'm laying the PCB board right now. If anyone wants to make the APK and arduino code, I will share it here if requested. If there is no one who makes the circuit, I will not share

I thought the detector with the display was great, I think you should go ahead using the display

I will wait the end and then order pcb if done. I dont want to use it with hand. Of course if you share android code also. After you test and say done I want to make it myself.

Hi. Thanks for sharing this project.
I supply the necessary components, if you say ok I want to make this detector. I don't want to start if the project is going to be unfinished.

I expected suggestions from you. However, no one wrote an answer. If there is demand, I would like to advance the project. Unfortunately there is no demand.

To complete the project, your support is required. I do not have a financial expectation. However, you need to have friends who will make and use the detector. That's what I expect.

Hattusa, I haven't said much on this project because it's stuff I've done before. However, it is probably a useful project for other people, and the more you include (like a display) and the more you share (like source code) the more useful the project becomes. Don't worry too much is there seems to be little interest initially, that's the usual case around here. If it's a project you are personally interested in and you want to share it, then keep going. If you're wanting a lot of participation through the development, well, that can be a disappointing journey.
