Hello,
I'm making my first detector, a surf pi. I took the pcb from pcbway. I am a total beginner in electronics.
I have a problem with my R25 resistor, it doesn't seem to be connected to anything...
I also have holes where nothing is indicated, do I need to make bridges? Where...

Noobie questions about Surf Pi 1.2
Sorry to bore folks with dumb questions. I'm trying to learn about electronics, but unfortunately I don't know much (yet!). Answers to any of the questions below are very much appreciated.
I assembled a surf pi 1.2 from Surf Dog. It works (3rd try), at least at a high level...took it... -
Is Silverdog still up and running?
So I'm new here (hi everyone!!!). Main reason I joined is because after a lot of online research this is like THE site for all metal detecting DIYs and modifications. Anyways, I ordered a Surf PI 1.2 kit from Silverdog.co.uk because it's what will suit my intended use (wet sand beach hunting) and wasn't... -
My first PI detector
Hi everyone,
To begin with sorry for my English, I'm french.
I just bought a surf PI 1.2 kit from silverdog, I made all the board and built a coil (24 turns, 20 cm diameter, 0.5 mm isolated cooper wire).
The problem is when I power the circuit, no sound comes from the piezo but a... -

Surf PI 1.2 discrimination mod
Hi I have built a PI 1.2 detector with spiral coil and pinpointer, took it out yesterday, worked great and picked up lots of objects including one which was a foot deep, however I would kind of like to discriminate between different metals with the PI 1.2 as the place I went was full of junk, does anyone... -
Reading Surf Pi 1.2 Output on Raspberry Pi
Hello,
I'm working on a design project in school. We were hoping to connect our Surf Pi 1.2, which we have up and running, to a sort of remote controlled car we built. However, we would like the audio signal from the piezo buzzer to instead be sent to the Raspberry Pi through the GPIO pins.... -
Surf pi 1.2 damping resistor
So after abandoning my surf pi project for two years i'm back and i want to finish what i have started. In the past i have wound 7 coils with different wire gauges and wire types, but i could not make it detect gold ring at all! Even when i touched it to the coil itself. Since i now have access to a... -
Problem detecting gold on surf pi 1.2
Hi,
this is my first post, so I would like to talk about me and my problem
I'm Carlos (mellao), from Spain, and I'm a little noob in this metal detectors world
I bought a surf pi 1.2 from silverdogs and I build it, and check the components a lot of times and it seems to be OK.... -
Surf 1.2 kit coil information
I'll get right to the point. I have ordered a surf pi kit from silverdog. My question here relates to the coil I can use. Can I only make a mono coil for the pcb board, or is it possible to wire in a dd coil. I am completely new to detectors, and am figuring with my background in wiring and soldering,... -
Help with surf pi kit please
Howdy all
Sorry but I am new to this. I am building a surf pi kit and i have few questions.
What sort of speaker should i use eg watt and ohm rating?
Can i use metal screws when attaching the coil and cover to the shaft?
When I put the coil in the... -
Surf PI 1.2
Hi there! Long time lurker here that finally had some time to built my first metal detector.
I've read every single thread under the Surf PI keyword from the forum in the last 2 days and i've saved up a few main threads if i get into trouble later on. I ordered silverdog's Surf PI 1.2 kit... -
Surf pi 1.2 not working properly
So i assembled surf pi 1.2 kit and tuned the offset pot so it reads 0v. Made a coil from solid core copper wire with plastic insulation it's 1.7ohms at 22 turns.
Started testing my setup with regular metal objects and it worked ok, but with gold is a different story... It just doesn't detect any... -
