Take a standard walkman-style headphone, the type that don't have a frame and are made to plug directly into your ear. Plug the jack into the audio input on your camera, then put the speakers inside the headphone cups on your head (don't put them in your ears, just lay them inside the headset cup). Sounds weird, but it works like a charm -- the camera will "hear" everything you do.

Just do a search on the name... BTW, NiMh is not always the best choice for a battery... They have a significantly faster self discharge rate than NiCad... If the photo gear is to sit for weeks between useage and recharge sessions you will be better off with NiCad, compared to NiMh... However, NiMh is definitely better when the cells are being used often, only partially discharged, and then recharged... They do not develop a discharge memory like NiCad does... But if they sit for a few weeks they will be flat just when you want them... The other option, is that when useage is sporadic, then alakline or lithium, non rechargeables may be the best choice... Their capacity exceeds that of rechargeables, their operational cost is far less, and when they are done you simply toss them and put in new ones... I had NiCad in all my cameras, head sets, walkie talkies, etc... When NiMh came out I jumped into it big time buying hundred of dollars worth of cells, chargers, etc... A big mistake - keeping the backup batteries in my GPS units, hand radios, Nikon F5, etc., charged and ready to go is a major chore due to the rapid self discharge of NiMh... As those cells are now finally beginning to wear out I am going back to NiCad for uses where I 'need' a rechargeable... But more than that, I am changing back to alkaline cells... I get them at the dollar store, flea markets, etc., anywhere I can get them cheap and still fresh dated... I keep a supply on hand in the plane, car, camera bag, etc., and simply toss the run down cells and install fresh... The old days may have been better, after all... Denny The real advantage of Lithium non rechargeables is the zero self discharge rate... These batteries can sit for many years waiting to be used and when the time comes they are ready to go ... Of course, that advantage costs more, but their ah capacity exceeds any other cell type and if your equipment has a heavy current draw and ahving to shut down to change batteries is a no-no they may be the best bang for the buck... ----- Original Message ----- From: "David.vonLinsowe" Subject: AeroElectric-List: NiMH batteries > --> AeroElectric-List message posted by: "David.vonLinsowe" > > > A little off aircraft electronics, but while on the topic of NiMH > batteries, where would you find the best rechargeable AA pencell type > NiMH batteries?

When I was searching for radios, I was told by several avionics shops that the traditional Garmin line of products should have cooling air ducted to the radios to avoid shortening the life of the radio, while the UPSAT line was engineered for lower power consumption and did not require additional cooling. Now that UPSAT has been acquired by Garmin, we should be clear that not all Garmins have similar requirements.

Oberst" Subject: AeroElectric-List: Pitch Trim Motor Slowdown --> AeroElectric-List message posted by: "J. Oberst" I previously posted a question on how to cut down the speed of my 12V DC pitch trim motor. I got one response, which suggested I use the the Matronics Mark III adjustable speed governor. I have two issues with this... first, it is unclear to me what the current capacity of this unit is (does anyone know that? - I am not using MAC servos)... second, it looks like a bit of overkill, as I don't want adjustable speed, ground-actuation, multiple switches - just a permanent slowdown to one speed. Can anyone explain to me what the design goal is for a DC motor slowdown circuit? I've been told that a simple dropping resistor could cause the motor to overheat. Also, I don't want to do something to reduce the torque. Will a fixed voltage regulator do it, or does it need to be pulsed, or?? Thanks.

I want to put cockpit audio into my video camera when doing test flying to get pictures of instruments & audio comments I make - should greatly reduce "head down in cockpit" time taking notes and greatly increase amount of instrument reading data collected." I did this fore selected flights but just stuck the recorder mike into one earphone and taped the wires for neatness. Adjusted input and it worked fine. Took ten minutes.

We have a 50 amp main alt. and the SD-8 on the vac. pad. My thoughts are about the elimination of the E-buss. If we loose the main alternator we would bring the SD-8 on line and simply turn off non-essential items bringing the total load on the system to 8 amps or less. In reviewing the loads on the system we come up with only a few that are not controlled by a switch. Clock and CD player keep alive and engine instruments. Clock and CD use less than a mA and will be on the always hot buss. That leaves the engine instruments as the only other loads not controlled by a switch. Instrument loads total .94 amps and if we add the battery contactor at 1 amp this results in a 2 amp load that we would not have control over. Leaving the question, is 6 amps enough to run the items we will need for a safe completion of the flight. If the answer is yes, then why not simply leave the load reduction to the pilot who would switch off the non essential items and illiminate the E-buss. This gives the pilot the option of turning on an item that might have been relligated to the main buss but could be useful for a short period of time and then turned off again. It looks like the items we would place on our E-buss run between 5-6 amps. So the loss of the 2 amps (instruments and contactor) buy simply staying with the main bus and turning off items to reduce load would seem to make sense. So in the event we lost the main alt. ...we would... move the Master to Bat, move the Aux Alt to on, turn off all unnecissary loads. At the airport, battery still up, put the gear down and land. Am I missing something? Bob your critic of my thinking would be appreciated.

Bob in your book under note 5 you write: "make sure that jackets for engine controls do not ELECTRICALLY ground both a metal panel and the engine ... they can easily become a SECOND ground path on the wrong side of the airplane and create the same problems we're striving to eliminate. This was for airplanes with battery and engine on opposite ends of the airplane. I have the conventional engine on front, firewall, panel, battery under the passenger seat. Do I need to worry about insulating my throttle and prop controls from the metal panel? I will also have several other (8 ) push pulls on the panel operating in the engine compartment. Though none will be connected directly to the engine. (9 cyl radial M-14). Any concerns? Another point. In the engine compartment we are using all stainless steel braided hoses. Several of which run from the metal firewall bulkhead fitting to the engine. Any concerns? I am planning on having all electrical equipment grounds run to a instrument panel ground bus located on the firewall as per your book.
