Best Audi A4 Motorized Ipod Tray - Hi friends Audi Sport Car, In the article that you read this time with the title Best Audi A4 Motorized Ipod Tray, We have prepared this article well for you to read and retrieve information from it. hopefully fill the posts
Article lainnya, we write this you can understand. Alright, happy reading.

This servo is designed for utilization inwards model aircraft to enhance in addition to lower the landing gear. It travels 180 degrees, has lots of torque, in addition to it's squeamish in addition to small. No, it's non terribly heavy, but at that topographic point is some friction to overcome, summation the arm has a large radius of nigh 1.5" to provide the needed 3" of travel. RC servos typically aren't that powerful in addition to are ordinarily used amongst shorter servo arms.
Here you lot tin give the sack run across the guts of the motorized drawer including the installed retract servo. The sides were fabricated from dark UHMW. Influenza A virus subtype H5N1 slot at the base of operations rides on the chassis plate. Influenza A virus subtype H5N1 plastic slice was cutting away from the residuum of the master copy storage compartment box. The unproblematic arm in addition to slot machinery has ii squeamish features for this application. First, linear speed is slowed at the ends of the travel. Second, it essentially locks the drawer when open, hence pushing on it won't movement it to slide dorsum in. The chassis is constructed of 1/8" 6061 aluminum plate that also serves equally component division of the slide mechanism.
I took apart a spare Firewire cable in addition to salvaged the dock connexion (unfortunately you lot can't simply selection these connectors upwardly at your local Radio Shack).
Here's the dock connexion mounted on the PCB. The connexion wasn't designed for PC mounting, hence it was pushed through a slot inwards the board in addition to and hence soldered inwards house on the go yesteryear side.
With the dock connexion mounted on the board, small-scale jumper wires were used to connect the pads to the tiny pins on the connector. (1)Audio business inwards out, including a floating signal ground. Using the dissever signal Blue Planet instead of the vehicle's chassis Blue Planet helps to trim hum in addition to alternator whine.(2)+12V furnish to ability in addition to accuse the iPod. The iPod includes an internal regulator that tin give the sack handgrip 8-30v, hence powering it take amongst the vehicle's 12v furnish is fine.(3)The Firewire TX pivot sends out 3v fifty-fifty when the iPod is asleep. It's used to command the good relay in addition to for the interlock feature.(4)Ground
Influenza A virus subtype H5N1 lilliputian dark pigment in addition to some safe feet consummate the connexion board.
This slice of UHMW (Ultra-High Molecular Weight Polyethylene) was machined amongst a router tabular array to provide a snug check for the iPod; the clearances are simply plenty to let the iPod to slide freely inwards in addition to out.
Here's the dock base of operations amongst the PCB mounted on the underside. The holes inwards the corners of the board were drilled slightly larger than the screws to provide a lilliputian wiggle room. With the screws all the same loose, the iPod was inserted to just align the dock connector, in addition to the screws were in addition to hence tightened.
Influenza A virus subtype H5N1 lilliputian metallic smoothen in addition to a slice of terrycloth on an orbital sander turned the 6061 aluminum into a affair of beauty!
The finished dock assembly looking all spiffy. And yes, I did smoothen the screws too.
The primary PCB includes a signal relay to switch the CD changer's good lines in addition to command circuitry to opened upwardly in addition to unopen the drawer. (1) DPDT signal relay switches betwixt the CD changer in addition to the iPOD's business out signal.(2)A unmarried LM556 dual timer IC provides the terra firma command in addition to also generates a PWM signal to drive the servo.(3)A 7805 regulator provides a constant 5v furnish for the command circuit in addition to servo, in addition to also isolates it from voltage fluctuations during engine starts.
This is the front end panel PCB that was mounted behind the master copy compartment door front. The small-scale SPST switch is positioned exactly where the mechanical latch machinery was hence the master copy OEM plastic clit could live used.
Here's the front end PCB mounted on the halt of the drawer. The mounting holes are oversized to let fine tuning of the check (there's non much clearance amongst the surrounding dash facia).
The front end comprehend was component division of the master copy compartment door in addition to required some tike modidications for its novel role. Some plastic to a greater extent than or less the clit opening needed to removed to accomodate the SPST switch on the PCB. Small UHMW blocks were glued on to secure the comprehend to the front end panel PCB. Influenza A virus subtype H5N1 small-scale hole was added for the condition LED.
This is the harness that connects the CD changer to the caput unit. The ruby in addition to white wires are the good lines that convey been cutting in addition to stripped.
I used a spare USB extension cable to consummate the harness. USB connectors convey iv conductors summation a shield, hence it's perfect for treatment the business bird good in/out.
In the closed position, it looks similar a stock A4 dashboard (except for the tiny LED adjacent to the open/close button)
Press the button, in addition to it extends out of the dashboard inwards nigh ii seconds. Pressing the clit volition unopen the drawer. Jam detection circuitry was used to feel an obstacle piece closing the drawer; it automatically reverses if it senses equally good much resistance. The iPOD is easily inserted into the adapter. The precise check in addition to dock connexion brand a secure mounting that has yet to come upwardly loose on fifty-fifty the bumpiest roads. The LED lights to dot that the iPod is fully inserted. Pressing the unopen clit does nil if the iPod is acquaint to forestall damage.

Below is a small-scale version of the Schematic. Hover your mouse over varous areas to croak a breakdown of that area's function.

Once removed from the dash, the compartment was disassembled into the box, door front, in addition to door back. The dorsum of the door was discarded in addition to replaced amongst the front end panel PCB. I decided to re-use the latch clit to retain a mill appearance.This servo is designed for utilization inwards model aircraft to enhance in addition to lower the landing gear.
