				I want to install my AV80R GPS in my panel and wire the power lead to the bus without installing a clunky cigarette power socket on my panel.  The GPS input voltage is 5V and it draws 1.5A (at least that's what the cigarette power lead says on it).  My buss voltage is 13.5V, so how do I compute the resistor ohm's and watts needed for my power lead?  I know enough about Ohm's law to be dangerous.
 Thanks.

				Just adding a resistor is probably not a good idea.  A resistor drops a 
 variable amount of voltage depending on the actual current consumption.  
 Additionally, your bus voltage will vary from 12V or less when the 
 alternator is off to as much as 14.2V when it is on.  Unless the AV80R 
 draws a constant current (unlikely) and can handle a relatively wide 
 voltage input, you really do need to use the power cord or some other 
 source of 5V.
 
 I couldn't find a manual to see what voltage it can handle, but given 
 they sell adapters for 12/24VDC and for 110/220VAC, it is likely that it 
 can use only a limited voltage (5V).
 
 The markings on the adapter almost surely refer to the adapter capacity, 
 not the exact consumption of the AV80R.
 
 For educational purposes, assuming that the AV80R actually did take 
 exactly 1.5A at 5V and your buss voltage was a constant 13.5V, you would 
 calculate the resistor value as follows:
 
 The resistor would have to drop 13.5V minus 5V or 8.5V at 1.5A.  Since 
 V=I*R or R=V/I, then R = 8.5V/1.5A or 5.666 ohms which is close to a 
 standard 5.6 ohm resistor.  If we used that resistor we would actually 
 get 8.4V drop which gives us 5.1V for the AV80R which would probably be 
 close enough.  The power dissipated in the resistor would be P=V*I or 
 8.4V*1.5A = 12.6W which would mean it would have to be a pretty large 
 wirewound ceramic resistor that would get mighty hot.  Of course, all 
 this is based on the paragraph above this one, which is highly unlikely.
 
 You can either find a 12V to 5V power converter to include behind the 
 panel or just use the optional cigarette lighter adapter provided by 
 Honeywell.

				Good Morning Al,
   
  I am sure you know more about Ohm's Law than I do, but why don't you  consider using a Zener Diode?
   
  If you use a resistor, the voltage output will change as the load changes.  I have no idea whether or not the load does change during operation of the AV80R  but dropping resistors do not work well at all with a varying load.
   
  Happy Skies,
   
  Old Bob

 Mornin' Al,
  
   When I first read your post, I didn't think the resistor was the way to go, either,
 same as Dick Tasker described.  My thinking was you're asking quite a bit from just one
 resistor.
  
   My initial thought was "why not build a 5 volt circuit" (like this one)?
  
 http://www.tkk.fi/Misc/Electronics/circuits/psu_5v.html
  
   Recently, I asked this forum if they knew how I could turn my Ray Allen servo resistance
 output (0-5K ohms) into a visual LED indicator.  Our buddy Joe Gores offered the perfect suggestion
  of a circuit referenced from Mike Linse.
    Included in his suggestion was that really handy 5 volt circuit above, plus it is super easy to build.
  The circuit had a final voltage output of 4.96 volts, and when combined with the circuit Mike Linse 
  talked about,  the whole project worked exactly as I was hoping for.
   
    From the article's data points about this 5 volt circuit, it says it may be limited to only
  one amp, plus you should consider a heat sink.  So I got to thinking......... 
   
    Here's a question for for you guys that rearrange electrons for a living.....could a guy
  build TWO of these 5 volt circuits, and combine the '5 volt output' in parallel?

				Thanks for the advice everyone.  I learned a lot with this thread.  I guess I'll stick with the cigarette adapter and mount the socket behind the panel where I can't see the ugly thing.

				Al,
 The rating on the 5 volt adaptor is what it is capable of, not necessarily what the GPS uses.
 There are options:
 1. Like everyone is saying, using a resistor by itself is a bad idea.
 2. A resistor and a 5 volt zener diode.  Without knowing the current requirements of the GPS, it will be trial and error.  7 ohms, 10W would be a starting point.
 3. You could build the 5v regulator circuit suggested by Mike Welch.  A 7805 in a TO-220 case bolted to the airframe and using thermal conductive paste.
 4. Take apart the OEM adaptor and solder wires to it and connect to the aircraft power.
 5. Buy one of these: http://www.mouser.com/ProductDetail/Murata-Power-Solutions/78SRH-5-2-C/?qs=35WhQNrE6p2lJ6BniHrImQ%3d%3d  Probably generates less heat than other options.

				First thing you want to do is build a solid state voltage regulator for a 5V
 output.IK can't remember the number on the chip but they are available at
 Radio Scrap.  
 The back of the package has a usable schematic.

				Only problem with that is resistors don't drop voltage unless they are set
 up in a voltage divider network.  They only restrict current.
 Don't believe me? Ok....  Try this; take a convenient battery and measure
 the voltage across the terminals.  Then connect any resistor to one terminal
 of the voltmeter and take another reading.  Guess what both readings will be
 the same!
 
 Now to check the current flow.  Connect a nice hefty resistor to one
 terminal of the battery and using a suitable ammeter measure the current
 through the resistor. Then add a resistor to one terminal of the ammeter and
 read again....  The second reading will be less than the first one
 indicating the resistor has actually dropped the current.  If you are unsure
 of the resistor sizes to try use a battery tester and a resistor to do this
 experiment.   
 
 If you want to build a voltage divider network with two resistors then that
 is another ball of wax.  The problem with that is the network loads your
 buss the whole time it is active and it will load your buss.  A solid state
 voltage regulator on the other hand will also load your buss but to a much
 less degree.
 
 Early model 45 field radios used a voltage divider network to give low power
 capability to the transmitters.  It wasn't long before operators noticed the
 batteries didn't last jig time if the transmitter was operated on low power
 mode.

				Yes... but another answer would be to us a circuit with more current capability.  Or possibly using the 7805 to switch a power transistor.

     This is also an option. The 3-terminal regulators
     are factory calibrated step-down voltage control
     devices.
 http://www.fairchildsemi.com/ds/LM/LM7805.pdf
     Unlike the "smart weight" I described earlier,
     these are more like "smart valves". Instead of
     working in PARALLEL with the output load, these
     work in SERIES. They have a distinct advantage
     for optimizing power dissipation (waste heat).
 
     As we studied in the Zener example, loads on the
     input power supply are constant irrespective of
     load demanded by the powered-up device. This is
     the least efficient means by which step down
     voltage tasks can be managed but they are
     SIMPLE. So you use them only in the smallest
     of situations were waste energy is not a significant
     design concern.
 
     The series-pass 3-terminal regulators will draw
     power from the supply that is only a few microamps
     more than the load demanded by the load. They
     are also easily adjusted. I used to offer a line
     of panel light dimmers based on 3-terminal devices.
 
 http://www.aeroelectric.com/Catalog/AEC/9013/
 
     Note that the larger the anticipated loads,
     the larger the device AND it's associated
     heatsink.  Now, if you don't mind taking the
     hit in terms of size, weight and disspated
     power, this technology offers a simple, low
     noise and relatively inexpensive means for
     acquiring a very high-quality (meaning low
     noise) DC power source for devices needing
     9 volts and less.
 
     This 9-volt limitation is due to the need
     for 'headroom' in the difference between
     input and output voltages. If you want
     the device to deliver, say 12 volts constant
     output, the INPUT cannot be lower than about
     13.5 volts. A 9v design goal for output
     can be achieved for inputs down to about
     10.5 volts.

				Mornin' Al,
   
  When I first read your post, I didn't think the resistor was the way to go, either,
  same as Dick Tasker described.  My thinking was you're asking quite a bit from just one
  resistor.
   
  My initial thought was "why not build a 5 volt circuit" (like this one)?
   
   http://www.tkk.fi/Misc/Electronics/circuits/psu_5v.html
   
  Recently, I asked this forum if they knew how I could turn my Ray Allen servo resistance
  output (0-5K ohms) into a visual LED indicator.  Our buddy Joe Gores offered the perfect suggestion
  of a circuit referenced from Mike Linse.
 
  Included in his suggestion was that really handy 5 volt circuit above, plus it is super easy to build.
  The circuit had a final voltage output of 4.96 volts, and when combined with the circuit Mike Linse 
  talked about,  the whole project worked exactly as I was hoping for.
   
   From the article's data points about this 5 volt circuit, it says it may be limited to only
  one amp, plus you should consider a heat sink.  So I got to thinking......... 
   
  Here's a question for for you guys that rearrange electrons for a living.....could a guy
  build TWO of these 5 volt circuits, and combine the '5 volt output' in parallel?
 
  
      Sure . . . or go to a bigger device. The 3-terminal regulators come
      in a range of sizes. The smallest are
 
  [img]cid:.0[/img]
     6 x 4 mm on a side, solder right to the board, and as you
     might expect, cannot dissipate much power. They're good
     for 100-500 mA max . . . but if your needs are small . . .
 
     At the other end of the spectrum, you can buy these guys
 
  [img]cid:.1[/img]
     Rated for 5A and MUST be on a hefty heatsink. Furhter,
     one can built arrays of transistors on even heftier
     heatsinks perhaps cooled with fans.
 
  
   [img]cid:.2[/img]
 
  
     I think the last time I built up something like this
     it was to craft a finely adjustable 50A, 28v load bank.
     There were 10 fat transistors on a big chunk of aluminum
     cooled with a fan. This rig was good for 1400 watts
     of room warming dissipation all controlled by a little
     piece of plastic 
  [img]cid:.3[/img]
     and a 1/2" diameter potentiometer.
 
     The point to be made here is that the series-pass,
     smart regulator can be crafted in just about any size
     and output voltage within ratings limits for the
     devices. 
 
     Bob . . .

				So, like I said, I chickened out and decided to use the car charger unit that came with the AV80R.  I was able to pry the case apart and inside was a 1"x1" 12v-5v DC to DC power converter.  I cut off the leads to the outside contacts and soldered on longer leads.  For a case for the power converter, I simply used the existing one and routed the leads out the nose to a Molex plug.  I'll secure the case behind the panel with an Adel clamp.  Here is what it looks like.
