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.

Subject: | Kuntzelman landing taxi recognition LEDs |
Folks,
Does anyone have any experience good or bad with the Kuntzelman LED landing
lights?
http://www.kestrobes.com/beacon.htm#LL1
They are only 3" diameter which makes them perfect for the limited space in
have at the front of the Kitfox. They co$t a bit so it would be nice to
hear if someone has been using them before I buy one.

I meant the cheap (almost free.. 1 - 2 $) stuff things. 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.

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.

Hi Sacha
"They co$t a bit so it would be nice to hear if someone has been
using them before I buy one."
I purchased one and also an AeroSun. Not flying with them yet but did
comment and document performance against several other lights:

Subject: | 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).

Just realized that for $55, there is also the open-source AEC9012-1 from
Bob's website which can flash a single LED

Hi Sacha
A couple of questions:
Heat sink: you mention it would need 60 sq. inches of heat sink. 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?
