DeePI (Felezjoo PI variant)

[MDfanatic]

This is DeePI, a compact SMD variant of Felezjoo PI made to fit in small enclosures (100mm X 50mm PCB size).
All major components are on-board, the only needed external wires are for the battery and speaker.

For battery you can use 4 X 18650 in series (14.8V) and adjust R19 pot until the screen displays 18V with fully charged batteries.

DeePI on OSHWLab (EasyEDA)

BOM file included, It will appear once you save the project on your projects.

HEX file:
DeePI_3.35-FullEdit.zip








Please note that the board has not been built or tested yet.

This is my second attempt and there might be minor errors, in case you spot any please let me know so I can correct the PCB.

Thanks, could not figure out how to see schematic, I ran the DRC and it threw up some errors.

[MDfanatic]

Thanks for the reminder, forgot to check it.

cant find any pcb files files, link is dead?

I've made the project private for now because I want to build it first to make sure everything works OK and then I'll make it public again.
I was hoping someone else could verify the design but it's better to check it myself. Being a smart@$$ take its toll.

This project looks promising to me

[MDfanatic]

I'll have to make minor changes first to minimize the PCB as much as I can, there's plenty of space going to waste for no reason.
I hope too that it works as it should but I was a bit too eager to release it

[Emersonpaz]

Did you give up on the MDFanatic project?

[ArchibaldSTM]

Probably the project turned out to be successful and moved into the category of commerce ...

[MDfanatic]

The project is still alive, although I've changed my mind as to how I will give this to the public.

I took my time to learn how to 3D Design and made a complete 3D printed collapsible body to accomodate the board.
I will create a new topic as it will be somewhat a big project (many parts to print) but I think the end result will be worth it.

There are only some minor bits & pieces left to be designed but it's getting along nicely.

In real search in nature,field, forest etc, the design is not compatible , very fragile !!!! my opinion, sorry

[MDfanatic]

Of course it is not even close to commercial metal detectors, it's a kid's toy built for big boys.

It is not meant to replace a commercial MD, it was made out of necessity and because I didn't want to spend more money to build it.
I already had the PLA and it's relatively cheap (13€/Kg) so I gave it a shot.

Although I will disagree on the "very fragile", it all depends on the orientation of the print. Each part is printed in different orientation and this adds to rigidity.
I already made some rigidity tests and so far it seems strong and durable, when it's finished I will make a video with all kinds of tests (detection distance, durability, battery life etc).

But again, this is a DIY project, not a commercial metal detector. For the money it cost me so far to print the whole body (5-6€ of PLA) you can't get something better.
