Being Deaf And Metal Detecting, Idea's (no its not me)

MarkCZ

Well-known member
Looking for some information or idea's for someone who used to metal detect but has now lost their hearing. I know that for the deaf community they make all kinds of things to help them in the hearing world, things like,
When the phone rings a room light blinks,
Their alarm clock has a little vibrating device that they put under their pillow.

Now I'm thinking of the vibrating idea, lets say the audio output is adapted or hooked up to drive a small vibrating system (a tiny out of balance motor). The unit could be plug into the detector's headphone jack and strapped to the arm of the operator via a velcro strap.
I would think the detector would need either fixed or automatic ground balance,
Maybe a target ID meter.
Discrimation set to reject iron and or other targets (null them out = no output)

Other idea's?
What would it take to hook up a vibrating system? What would be nice would be one that would respond at different speeds based on the intensity of the audio output. That way a deeper target wouldn't hit the vibrator with as much signal and would vibrate with less intensity. But I guess first is to just get it to vibrate over a good target to signal a response so the user can then cross sweep and use the meter's visual ID system, I would also think that with pratice pin-pointing wouldn't be a problem either.

Anybody got any workable idea's?

Thanks


Mark

Remove the headphones , and just splice in a vibrator ( of some type ) into the headphone wires. Hook the vibrator to the inside of his wrist. ( maybe under a wrist band ). Every time there is a target "buzz buzz" . Then dig it all !

Well a vibrator of some sort is the question and a way to drive it.
One of the little vibrating cell phone motors would be great, but from what I can find out the headphone output isn't enough to drive the motor. So, some sort of small circuit would have to be made using its own battery power supply and a switching device that can be triggered via the headphone output, Like,
Transsistor,
SCR, the problem with these are once they're gated they stay switched and so they take another circuit to turn them off, or completely disconnect the power source.

I'm not a electronics guy, but a computer guy. Anyways it would seem rather easy to fabricate a LED board with different colored LED's. Each light tuned to the internal frequency(s) of a particular discrimination zone. A clever electronics hobbyist, and we have lots of them here, could make some serious cash fabricating and selling this item. On tone capable detectors it could simply be plugged into the headphone jack.

Or conversely, a particular vibration could be issued through skin contact device, also based on above tones. Then detectorist won't have to be looking @ lights/meter all the time.

There's two ideas.
 
Plug your hd phones into the 280 with it attached to your shaft. You can feel the viration easily. Kelyco used to sell these.

That's it the Vibra Phone would work, its even made for metal detectors! :smoke:

Thanks for the information I'll pass it along!

I'm still open for other idea's as well.

To keep it simple, a speaker is a vibrator (coil vibrates the cone to make sound). One made for a MP3 player or hand held radio could be strapped to the inner wrist and no one would have to build anything. Plug it in, velcro it where you wanted it and hunt.
Or
the vibraphone
 
Okay, I found it,

I wonder whats the deal with it not working on Fisher and Mine-Labs detectors? I can't see why it wouldn't.

I see little value in a "generic" non-discriminating vibration device. A discriminating vibration device, as I mentioned in above post, would allow the deaf/hearing impaired the benefits those with more normal hearing enjoy.

I like your idea and here is something I found, it could be built by a local electronic hobbyist or a local Amateur Radio Operator (HAM) or about anyone in electronics service and repair. I have built these circuits in the past and this one wouldn't take long even if your a beginner

Hope this helps!

TerraDigger's idea is already in production and in use on the White's Beach Hunter ID, which uses red, yellow and green lights for various targets. I would think it would be fairly simple for some one to come up with something similar and couple it with a vibrator that also signals a target.
 
How about a screen full of small led's or small heads-up display with a pinpoint area that moves in unison with the pinpoint area of the coil? Use different color light to show the differences in conductivity of a target? I'm no engineer so I could be way off here. Might be mechanically, electronically or physically impossible?

HH, crispy critter
 
Heck....lets go all the way and make it a holographic display.
 
Maybe I can help your friend. Several years ago I had a Bullseye pinpointer that the little speaker started to sound crappy and not loud enough. I put an led in the speaker's place and mounted it in the side of the unit. It works just fine, but I never use it. If he/she wants it send me their address.
 
seen this on youtube. seems to work pritty good...... http://www.ebay.co.uk/itm/STEALTH-DEVICE-GARRETT-ACE-150-250-350-METAL-DETECTOR-/130571113233?pt=LH_DefaultDomain_0&hash=item1e66a51311

We have had as many as seven deaf members in our club at one time. They all use detectors and do very well. Some have a Vibra Phone on their machine. If memory serves me right, Vibra Probe makes them. Also the gusy have come up with other ideas that suit them well. We have one of the biggest clubs in the US and have interpreters at every meeting. I wrote a story in the fall of 03 I think for W&ET magazine about the deaf and detecting.
