Surf Pi Professional Pcb's back in stock - NEW Prices

[monkeybaby]

Surf PI is not easiest project here to start (there are some simplest BFO projects for beginning), but you ca try.

I shall give it a good goanyway, out of interest where could I view the other projects and do they come in kit form?

Really fancy having a go at this but wondered what else is required to complete if I bought KIT1: 1 x PCB plus all PCB components $45 US. I realise Id have to make a coil, shaft and pcb housing. Im quite new to electronics but can solder well. Im in Scotland in the UK.

Thanks Rob

Yes, in general you need to make plus coil, shaft and housing to get your complete PI.

Good Job! I think I have everything laying around that you used.. What did you use for speakers? I have been thinking about using those flat ones that come out of greeting cards. The ping pong ball is an excellent idea!

Here's how you can make high impendansne Headphones http://makearadio.com/misc-stuff/piezophones.php and http://www.hpfriedrichs.com/rr-pzphone.htm

Hi Don, I want to show you my Waterproof Headphones setup.

I've used a pair of 3M ear defenders muffs (don't remember the model). As you can see inside of the ear def. muffs there are two ping pong balls. Inside of each ball there is a 8 Ohm speaker glued to a small plastic sheet (a piece of plastic taken from a VHS case). You need to put a ring of hot glue cord around the balls to keep them attached to the plastic , then you need to put another silicone sealant cord around the balls to make them waterproof (or you can cover the ball completely with silicone, that's up to you). I've used a Heyco® Liquid Tight Cordgrips Straight-Thru at both sides

Waterproofing

Hello, I am also interested in PI detectors for beach hunting, I have recently finished my Jabel kit. I wonder how to make a waterproof detector (IP67) for shallow water hunting. And also, is there an easy way to use vibration and meter/flashlight instead of audio? Waterproof headphones tend to be rare or expensive

[silverdog]

Hi

I sent you an email

[bernte_one]

Hello silverdog,

did you have any boards maybe 2 or 3.

Please contact me with pm.

greetings from berlin

[Tilladude]

You can check flea-bay or the for sale sections of detecting sites, of course you could purchase one from White's I'm sure they have a few hang'n around.

I just ordered a kit, but my goal is to use it for Prospecting (not a lot of sandy beaches on Colorado). I have wanted a PI detector for a while (I have a Whites GM V/Sat and GMT already for Prospecting, along with Coin and Relic detectors).

I can find TDI coils if need be.
