Eric's dimmer that I cited earlier is a linear regulator . . . LM317 based. It's not a noise generator. If you want to go one step further up the DIY ladder, you can craft your own dimmer from parts readily available at RadioShack and others. Don't let logistics of acquisition dry up your creative juices.

They co$t a bit so it would be nice to hear if someone has been using them before I buy one.

But they are nice to start playing with. The LM317 is a very nice analog circuit for LED:s! And one more thing is LM317 will not have is that annoying flickering that especially comes with simple switched circuits. The best way is to just rig up some stuff and play with it before putting it into a plane. >> found a nice small thing on ebay http://www.ebay.com/itm/LM317-DC-In-5-24V-Out-1-5-15V-Volt-Regulator-Converter-/121173879393?pt=AU_B_I_Electrical_Test_Equipment&hash=item1c3686aa61 Enjoy! //// Sauli ________________________________ Message 5 _____________________________________ Time: 07:43:18 AM PST US Subject: Re: AeroElectric-List: 5 Meter LED String Info From: Robert Borger Bob, I have one of Erics dimmers on order. I selected it for the reason you state, lower noise potential than a PWM dimmer. Im not quite ready to start crafting electro-goodies myself yet, but would like to get there once all aircraft have been built and are flying.

I purchased one and also an AeroSun. Not flying with them yet but did comment and document performance against several other lights: http://www.europaowners.org/main.php?g2_itemId=30987 Ron Parigoris ________________________________ Message 7 _____________________________________ Time: 09:21:53 AM PST US From: "Sacha" Subject: AeroElectric-List: Landing light LEDs - questions about Heat Sink and Flasher/Wig-Wag Noise http://www.europaowners.org/main.php?g2_itemId=30987 Thanks Ron for that! A couple of questions: Heat sink: you mention it would need 60 sq. inches of heat sink. How did you come to this number? Does it assume that the sink sits in a free stream of oncoming air (I'm thinking that my heat sink would end up under the cowl which may not be the optimal place for it, so it would need to be even bigger, which would defeat the purpose of choosing the LED in the first place). Wig-Wag/Flasher: I'm planning to have just one landing light (no taxi light) so more than a wig-wag, I really need a flasher of sorts. I'm considering three alternatives right now (I originally thought of the B&C SSF-1 wig-wag but doesn't work unless two loads are attached): - $6.99 An automotive flasher such as http://www.ebay.com/itm/1x-3-Pin-CF13-Car-Flasher-Relay-to-Fix-LED-Light-Bli nk-Flash-/251289748449 which I suspect may be noisy. Does anyone know for sure? Is there an inexpensive way to cure this? - $45: Kuntzelman wig-wag controller which is capable of flashing one or two LEDs. - $88: Perihelion wig-wag. I understand this is not noisy, but probably overkill (it apparently can flash two 250W sources, my LED consumes 20W).

How did you come to this number? ** I spoke to the owner. I forget the exact details now, but I would be using it as a Taxi LED so it may not be getting much airflow some times. ** I went with Erics flasher. That said you may be able to find a automotive LED flasher that could be used. I fooled with one, let it run for a while and it failed. Very poor quality. If that is your only LED, you can speak with Dick about his. I was at the Javitz center this past Sunday (bike show) and saw some pretty slick LEDs from Denali.: www.TwistedThrottle.com The DX is the largest, 10 watts per LED and 10 degree angle and has dual intensity, 3" square 3.75" long The D2, kinda slick, it comes with two lenses a 10 degree and 25 degree 10 watts per LED, 2" square and 2.4" long, dual intensity The baby DM 1.75" round, 2.4" long, 5 watts per LED, comes with both 10 and 25 degree lens, only 1 intensity Tell them you were at the bike show, you may still get a deal! If you only need one LED and decide on the D2, I will buy the second one from you. They have a pretty nice integral heat sink. You can call them and see if they offer a flasher/wig-wag?
