but it's not peer reviewed!! look at these terrible errors below!! (this is the "Pot calling the kettle black!")

Yes Huego, remarkable even for me, but most important is how it can be "perforable" in soil.
Hola Amigos,
Please don't be too critical--these are STUDENTS! They have a lot to learn and they have chosen a field where the opportunity to learn is limitless. I appreciated the innovative Wein Bridge. It wasn't specified whether it was
using Rotwein or some other kind. I like Cabernet Sauvignon myself and the circuit would definitely be unstable as the wine is consumed during the project. There is another version of the oscillator known as the WIEN BRIDGE,
which uses only electronic components.
It was predictable that Huego (aka Juego de Palabras ) would point out the typos--but are they typos?
My criterion is: If it's misspelled once it may be a typo, misspelled twice, it's illiteracy.
Thanks for finding the article, WM6, it was amusing to read,
Allan
P.S. The detector is definitely eco-friendly: When the detection depth is only 6", the hole in the ground is easily filled with the foot.
Hola Allan & fellow lovers of words, nuances & parables,
It’s a fun article to read although they lost me with the electronics.

Thanks WM6.
Yes, Allan, the students are on a journey, setting their goals high. One day they may even laugh at themselves, from their corporate towers, at what they wrote.

Any fun is light-hearted replacing the lack of inter-gender talk.

My own electronic education is so limited that I would never have picked up on the “Wien Bridge”.
Peraps this innovative “wein bridge” was formed, with a
zzzzzzzzzt, after a spillage of some closed circuit wine (wien) causing cross talk or short talk.
Peraps its lyrical illiteracy. Who am I to judge .... I just play with words.
Kids of today don’t use spell checkers coz they use abbreviated text in communication (life is short enuf without wasting more on spelling & grammar).

The Group spent so much time winding & testing coils they ran outa time to get the discriminator working & gps integrated. I bet they "learnt heaps" …… spelling can wait.
The GPS portion of the final project was also abandoned due to time constraints. Efforts that would have been used on the GPS were focused on to the discriminating and object identification aspects of the final project during the final weeks.Commendable that they were so goal-oriented (aware of design specifications) & environmentally conscious ….. a good sign in youngsters these days. The generations after will be even more so. They will need it for their survival.
Question:
Could they have learnt more by retro engineering methods? Pulling a 3030 apart and wondering at its simplicity vs cost & innovation.
If they did they would get a laugh when the saw the
WHITE (WEIN) PAINT over the PCBs & remembered their own spill!!
Huego
