Targus RemoteTunes for iPod

Comments 0 Comment

This is the Targus RemoteTunes(tm) for iPod. I got it from XSCargo, where they currently have them available for CDN$9.99.

Its guts include a transmitter and receiver pair. Even considering I don’t have an iPod to use this with, for $10.. I’m not arguing.

The receiver has:

The transmitter has:

The receiver and transmitter both have some unused pins on them:

Receiver (Base):

  • J: ICSP Data 
  • C: ICSP Clock
  • V: VPP / !MCLR
  • G: Ground
  • +: 3.3V from iPod

    PIC Pins:

  1. Power (Vcc = 3.3V)
  2. ?
  3. (Something to do with the output jack)
  4. VPP (Programming Voltage) / !MCLR (Reset)
  5. Data (From HiMark Pin 8)
  6. ICSP Clock
  7. ICSP Data / Serial Transmit
  8. Ground

    HiMark Pins: (Pages 11-12 of Datasheet. Pins I especially care about are un-italicized.)

  1. Oscillator 2 (From Tunable Coil)
  2. IF filter output
  3. Comparator input A
  4. Comparator input B
  5. Comparator offset adjustment
  6. Ground
  7. Ground
  8. Data (to PIC Pin 5)
  9. Disable
  10. Comparator input C
  11. Limiter Input
  12. Limiter Feedback A
  13. Limiter Feedback B
  14. RF Amplifier Input (Virf)
  15. RF Amplifier Ground (Vee)
  16. RF Amplifier Output (Vorf) 
  17. Mixer Input
  18. Power (Vcc = 3.3V)
  19. Power (Vcc =.3.3V)
  20. Oscillator 1 (To Tunable Coil)

Transmitter (Remote):

  • J: VPP / !MCLR
  • C: Serial Programming Clock
  • Unlettered: Serial Programming Data
  • G: Ground
  • +: Batteries (6V)

    PIC Pins:

  1. Power (Batteries)
  2. ?
  3. Play/Pause Button (Center)
  4. VPP (Programming Voltage) / !MCLR (Reset)
  5. Volume Down (Bottom Left)
  6. Volume Up (Bottom Right)
  7. ?
  8. LED
  9. ?
  10. Crystal?
  11. ?
  12. Serial Programming Clock / Back Button (Top Left)
  13. Serial Programming Data / Forward (Top Right)
  14. Ground

Ok, just starting out, but I’m going to make a shutter control as described here: “Super Mini Switch – A RS60-E3 Replacement”.

Parts I have so far:

From a broken Casio calculator:
2x Calculator Buttons (I’m trying to decide which ones, I’m thinking either C (red) or EXP (grey) for exposure, and ‘.’ (blue) for focus)
1x Rubber Layer with buttons to trigger touch sensor

From a broken CD Player:
1x 3.5mm Stereo Plug

From my cool junk pile:
1x Touch Sensor

From an old machine my dad got from work:
1x SPST Toggle Switch (Off/On)

From Dallas Semiconductor:
1x Plastic Box for shipping and storing ICs

It’s a shame what people throw away, really. I found the “Broken CD Player” smashed to pieces on the ground, ditto with the Casio calculator. Total cost so far: $0

Update: Stuff I got from the Dollar Store for the project:
Cell phone headset (for the 2.5mm plug) ($1)
