This is a person that had tried the original raw driver and who had sever problems with noise. This will be a good test because he knows how they performed before and he will know after. Currently he replaced the drivers with resistors. His application also has a Archer wingtip Nav antenna and he plans on putting the modified driver on that side so we can see how it affects Nav radio performance as well. It will take a few days but we will get some real airplane testing done! It looks very promising when just comparing it to the way they affected the handheld so I expect the aircraft will have similar results. Bob are you planning to market these or just give us the sources and info needed to build our own? Thanks for your help Bob!

Handheld can be as close as >the antenna touching the power wires with no noise. Very good data. It looks like we could consider a bit more attention to the VHF spectrum outside the boundaries of the existing filter. But I suspect that the present configuration would be clean enough for service without the ferrites. >Seems we are very much on the right track.

I have more boards and parts but no power supplies (you supplied the one we used). Do you want me to assemble one or send you the parts? You'll note some chop-n-hack on the board where I corrected a layout error. Perhaps I just need to correct the layout and then publish the ECB art along with a bill of materials. You guys can probably run with it. All the parts come from Digikey. >I do not have a panel mount to test. This would be the ultimate test as >the driver and the radio would be sharing a common power supply. Given the results of your experiment with the hand-held as an e-field sniffer, I think the present configuration would play well in the airplane. I'm still planning on getting into the RFI lab out at NAIR. I attended a meeting out there last night and bugged 'em about it again. You think government and industry are wading around hip-deep in bureaucratic mud, take a peek into a university some time!

Bob since you have the parts and the boards and know how you modified the board to make it work, could you assemble one more for me? I could send you another driver to install. I am more than willing to pay you for the work and shipping, just let me know what that would be. As far as future ones, I am sure there are some that would be OK will assembling their own and I am sure that there are some that would rather you just sell them a completed one. To minimize the stress on your end, if you could just publish the board art, bom and sources, I am sure that would be OK with most people. Let us know!

Okay, I did the sharp pencil treatment on a filtered LED driver as follows: AEC9051-1 1-Amp, LED Driver Assembly similar to . . . http://aeroelectric.com/Pictures/Lighting/Buck-Puck/BuckPuck_1.jpg except connector will be right angle version and exit the board parallel to the mounting surface as opposed to standing up. Board will be fitted with the LuxDrive 03021-D-N-1000 1A LED driver module and filter components shown in http://aeroelectric.com/Pictures/Lighting/Buck-Puck/BuckPuck_4.jpg http://aeroelectric.com/Pictures/Lighting/Buck-Puck/BP_Filter_V1p1.pdf A complete kit consisting of board assembly, mating d-sub connector, connector hood and machined d-sub pins as shown in . . . http://aeroelectric.com/Pictures/Lighting/Buck-Puck/BuckPuck_3.jpg (except for connector orientation). I'll need orders for 20 assemblies to break even for tooling up and bringing in unique inventory (ECBs and Buck-Pucks). Price for each assembly as described is $46.00 plus postage.

I ask because I don't understand if the gizmotron is in the fuse with output to the two wingtips; or if a gizmotron sits in each wingtip. Soon as I know you'll get my order and probably another one from another builder here too.

You could use one but with reduced drive current to each string of LED's. This driver can source 1000mA of current.
