New version (Beta):
In this version this metal detector works with a smartphone or without a smartphone with the possibility of adding an LCD screen. Now Spirit Pi is more stable and reaches more depth. The diagram and the PCB can be found below, also in the file you will download will be gerber file in case someone wants to order the PCB on the JLCPCB page. JLCPCB is a page where we can order the PCBs we want for a very low price, we just have to upload gerber file of the circuit and that’s it.
News:
Now in this detector we have 3 buttons: “+”, “-“, and the “M” menu. With these buttons we can adjust the pulse width, sensitivity and frequency. Instead of the TL072 amplifiers we will use NE5532. The micro controller will use an Arduino nano. The coil is still 25 turns with 0.5 mm wire and the radius 20 cm.
Components:
The components I usually buy on Aliexpress for the low price. In this way we can make a good metal detector and spend little money. Below I will leave the links where you can buy these components to make this metal detector!
Big thanks to whoever wrote this, you saved me a lot of time hunting for the same info on other sites, and a stop at sunhavenessentials only added more useful detail without going off topic, that kind of focus is honestly hard to come across these days when most posts wander everywhere.
Felt this in a way I cannot quite explain, the topic just hit different here, and a stop at brightforgecraft continued in that vein, sometimes you find a site whose perspective lines up with how you have been thinking and reading their work feels like a small relief which I appreciated more than I expected.
Did not expect much when I clicked through but ended up reading the whole thing carefully, and a stop at digitalcartzone kept that engagement going, sometimes the unassuming sites turn out to deliver more than the flashy ones which is something I have learned to look out for over time online lately and across topics.
Appreciate that you did not pad this with fluff to hit a word count, the post says what it needs to say and stops, and a look at nextlevelcart did the same, brevity here feels intentional not lazy which is a distinction many writers miss completely sometimes when they are working under deadlines.
Will be sharing this with a couple of people who care about the topic, and a stop at radiantcoveessentials added more material worth passing along, the kind of site that is generous with quality content and does not make you jump through hoops to access it which is appreciated more than the team probably realises.
Now appreciating that the post did not try to imitate any other style I might recognise, and a stop at cartwaymarket continued that distinct voice, content with its own register rather than borrowed from elsewhere is content with real authorial presence and this site has clearly developed that presence through what feels like patient editorial work.
Reading this gave me something to think about for the rest of the afternoon, and after urbantrendcenter I had even more to mull over, the kind of post that lingers in the background of your day rather than evaporating immediately is genuinely valuable in an attention economy that punishes depth rather than rewarding it.
Reading this slowly to give it the attention it deserved, and a stop at goldenshoremarket earned the same slow read, choosing to read slowly is a small act of respect for content quality and very few sites earn that respect from me but this one did so without any explicit ask which is the cleanest way.
The pacing of the post was just right, never rushed and never dragged out unnecessarily, and a look at instanttrendmart maintained the same rhythm, you can tell the writer has experience because the difficult skill of pacing is something only practiced writers manage to handle well in long form content over time and across formats.
Reading more of the archives is now on my plan for the weekend, and a stop at clevertrendcenter confirmed the archive worth the time, the rare archive worth a dedicated reading session rather than just casual sampling is the rare archive of serious work and this site has clearly produced enough of that work to warrant the deeper exploration.
Glad I stumbled across this post, the explanations actually make sense without needing background knowledge to follow along, and after a stop at infinitytrendzone the same was true there, no assumptions about the reader just clear writing that anyone can understand from the first line right through to the end.

Bookmark earned and shared the link with one specific person who would care, and a look at twilightfieldmarket got the same targeted share, sharing carefully rather than broadcasting is a discipline I try to maintain and this site is generating shares from me at a sustainable rate rather than the spam rate of viral content.
A thoughtful read in a week that has been mostly noisy, and a look at aurorastreetgoods carried that thoughtful quality across more pages, finding pockets of considered writing in a week of distractions is one of the small wins of careful curation and this site is providing those pockets at a sustainable rate.
Bookmark moved to my permanent reference folder rather than the casual maybe later folder, and a look at premiumcartzone earned the same upgrade, the distinction between casual interest and lasting reference is something I track carefully and very few sites cross that threshold but this one did so without much effort apparently.
Top notch writing, every paragraph carries weight and nothing feels like filler, and a stop at stylishdealzone reflected that same care, a rare thing on the open web these days where most pages exist for clicks rather than actual reader value or anything close to that which is honestly a real shame.
Reading this between two meetings turned out to be the highlight of the morning, and a stop at amberpinecollective continued that highlight quality, content that outshines the structured parts of a working day is doing something well beyond ordinary and this site has produced multiple such highlights for me already this week alone.
Glad the writer did not feel the need to argue with imaginary critics in the post itself, and a stop at goldenbuyzone kept the same focused approach going, defensive writing wastes the reader time and confidence on positions that did not need defending and this post has clearly avoided that common failure.
The structure of the post made it easy to follow without losing track of where I was, and a look at prismridgeessentials kept the same logical flow going, this site clearly understands that organisation is half the battle in keeping readers engaged from the first line to the last across any kind of post.
Nice and clean, that is the best way to describe the writing here, no clutter and no wasted words, and a quick visit to ambergrovecrafts kept that going, I appreciate when a site treats its readers like people who can think for themselves without needing constant hand holding through every paragraph.
Worth saying that the writing carries a particular kind of authority without making any explicit claims to it, and a stop at clevergoodsarena extended that earned authority feeling, sites that demonstrate expertise through the quality of their explanations rather than by stating credentials are sites I trust most and this site has it.
Bookmark added in three places to make sure I do not lose the link, and a look at bluepetalstore got the same redundant treatment, sites I am afraid to lose are the rare keepers and this is clearly one of them based on what I have read so far across this and a couple of related posts.
