Mod a Stanley Intellisensor Stud Finder

[Deewayne]

Part 9

This picture shows how the electronics sit inside the PVC.

Now put the PVC parts together except the bell reducer to the 1 1/2" pipe.
Slide the electronics into the pipe.

Now it's time to tune the coil. Here's the steps. you will need a small screwdriver, penny, dime, and a quarter.

1. Make sure the coil is clear on all metal objects including you watch and rings.

2. For a starting point turn the adjusting screw on the blue resistor 1 1/2 turns count-clockwise.

3. Press and hold the push bottom switch. The green LED and the #3 LED light and the buzzer will beep.
The red LED and the buzzer will go off (green still on.)

4. Take one of the coins and bring it close to the coil. As the coin gets closer to the coil the LED's will light
in sequence, 1, 2, and 3. Do this with each coin.

5. If the LED's do not light or the range is to short, keep adjusting the coil. To do this turn the adjusting screw 10 complete
turns clockwise. Repeat step 3 each time you make an adjustment. Turn the screw 1/4 of a turn count-clockwise.
Then repeat step 3. Keep making the 1/4 turn adjustments until you get the results in step in step 4.

End of part 9

I know the parts list doesn't match 100% but I can't edit the previous post.

Something's your going to have to figure out yourself - expand your brain.

Good Luck

What kind of range are you getting on this? I'm looking into modding a cen-tech into something like what you have, but if the stanley gets better distance then I'll have to reconsider..

 

[Deewayne]

In open air test all the coins ( D, P, N and Q) will cause the first LED to come on
5.5" to 6.5" from face of the coin.

If you don't like the range, tune it to suit your needs.

 

[TN Mike]

That's some outstanding range lol. I'm gonna look into this and see about adding different audio output for each LED. Farther away lower tone closer higher tone..Shouldn't be to hard.

 

[Deewayne]

If you get a working circuit please send me the schematic.

 

[TN Mike]

Will do. Thanks for your work here. Great addition

 

[Deewayne]

One thing you can do is shorten the handle to fit you hand.

Hi,
I tried to make a pinpointer from Stanley stud finder (the same one like Deewayne's one) . I made air coil diameter around 5mm with all dimensions mentioned in the first post.
Its working but its reacting on everything, ground , human ... The only diffrence is that I used enamel wire diameter 0.41mm.
What is the problem?
Thank you

The Stanley Intellisensor Stud Finder is not a metal detector. It senses a change in the capacitance of a wall surface caused by the studs behind the drywall.
The two open ended coils will act like the plates of a capacitor which is what the original sensor was.

I 'm going to try the electronics from a Zircon MetalliScanner M40.

I like the housing Deewayne designed for his pinpointer. I'm going to try the next size down in pvc pipe if I can.
Some of the cheap LED flashlights have a battery holder with 3 AAA batteries. two of these in series would provide 9 volts and fit into 1" pvc pipe.

Good luck everybody, I will post again if I have any success.
