Can I build this ecaller

Ok guys, I have decided that its time for me to stop paying with tapes and go digital.
I have two ideas, one is my ideal caller, the second is what I can live with.
I'm going to set the cost limit at 200 but would really like to spend less than that.
What I really want-
A digital caller than runs off an mp3 player, uses a rechargable battery like what is found in a JS 512 cassette caller, uses the JS long range horn speaker, and is remote controled with the control featuring a number pad to select sounds.
This I don't know if I can do so I need some advise here.

That I figure I will end up doing.
Settle for an mp3 based caller without the remote control. I would like to canabilize the batery and speaker off my JS 512, can somebody tell me if this is feasable.

Third option would be to buy a JS converta caller and an mp3 and be done with it.

What do you guys think on this. I read the tech section instructions but am unsure is I would be happy with the battery system used.
Need your advice and thanks in advance.

Here's what I did.

I started with the JS Converta Caller. Then I added an MP 4 player, and then a Nady DK W1 wireless mic system. My total cost was 225. I added a memory card to the MP 3 player later.

I think I have a great sounding caller with a rechargeable battery that powers both the Caller and the Remote, digital sound, and it all fits in the case that came with the caller.
 
Rio 600 - all day long on ebay for less than $30
NAdy 151 - Ebay for $50 to $60 (I got 3 for less than 50)
RS Mini amp - $12
Speco SP-5p - $20 delivered
Energizer Outfitter Flashlight - 19.95 delivered

Total = $132 to $142

Total remote control, sound selection, on/off, volume.
 
Guys,
Thanks a bunch for the imput. I Just checked A.E.H.'s page and everything is making sense. I never would have thought of using a wireless mic to take the place of a remote.
Now, anybody know have I can use my JS 512 cassete caller as base for the speaker, amp, battery.
Thanks Guys, I just decided today to go digital and I feel like I am already well on my way to getting there.

Hey one other question- Does anybody have the life expectancy on these wireless mikes? I really like the idea but I don't want to go down that road if they won't hold up for the long haul.

The Nady DK W1 that I purchased seems to be pretty well put together on the circuit board. I don't see why one would not hold up for a long time with genral care of the unit. The transmitter used the cable from the MP 3 Player to the unit for the antenna, and it screws into the transmitter for a very secure conncetion.

Mine is relatively new so I can't say for sure how long it will last. I'll get back to you in a couple of years or so /ubbthreads/images/graemlins/smile.gif
 
TheHuntedOne,
thanks and I will hold you to that. That way if mine goes flop I will have a new place to start. /ubbthreads/images/graemlins/laugh.gif
It looks like I am going to go the converta caller route, unless someone steps in and talks me out of it. /ubbthreads/images/graemlins/wink.gif

The difference between any coaxial auto stereo speaker and a powerhorn is like day and night. My powerhorns have been gathering dust ever since I discovered several of my most-used predator calling sounds simply cannot be reproduced by a horn.

You can easily find a pair of stereo speakers new for under $50 at any discount auto parts store, and they'll work with a small amp (There was some chatter on the board awhile back about potentially blowing out the voice coil with the distortion of a pipsqueak amp, but so far no problems with the 7W Velleman/Hobbytron amp I've been using).

I went the route of a small 4 inch speaker for awhile and blew it out one day when the volume control somehow got turned to max. Oh well. Went back to the power horn. I agree that the speakers sound better than the horn by a bunch.

As to the Convert a Caller - I modified mine a bit. I cut the 30 foot cord off to make it about 3 feet long, and then cut out the back of the case and rivited the horn to the case. Now all I do is set it down, turn it on and go get ready.

To give myself some back up incase the remote ever goes, I got a 20 foot head phone extention cable from Radio shack for about 8 bucks. I can plug that into the amp and MP 3 player if I llose the remote capabilities. Beter to have a 20 foot cord than a busted day in the field.
 
I have a JS Cassette caller and wanted the option of using CDs (bought or downloaded). I went to Walmarts and bought the cassette to CD converter. It has a cassette that goes into your cassette player and a plug that goes into your CD player. It allows you to play CDs through your casstte player using it's sound system. It works perfectly. I can now play casstte calls or CD calls through my JS cassette caller. I downloaded the chicken distress, you only have to burn it on the CD once. To play all you do is put your CD player on repeat track and it will just repeat that track over and over. Hope this helps.
