From: "Doug Gray" Bob K, I recall you had an Audio mixer board at one time and I would like to somehow get hold of one. IIRC it was attached to a 25Pin PCB mount D-Sub connector, with 3-4 inputs and a single output. This would be perfect for me since I plan to mix together the audio from an alternate radio plus the audio from an anunciating EFIS system and feed these to my intercom. For PTT and MIC I plan to fit a 2 pole 2 position switch to select between Radio1 and Radio2. Even if I could acquire the CCT and bare PCB that would be a great help.

I'm not aware of any thermoelectric products that go beyond a hand-full of watts capability. That technology goes back a very long way. Here's a small step back in time to when thermoelectric power generation became commercially practical technology: http://tinyurl.com/2gshpm and a modern incarnation: http://tinyurl.com/ytv3th >Its a little frustrating here in New Zealand there is a manufacturer of >stirling engine power generators for boats and homes - called "whispergen" >- however they ony seem to supply to certain markets and that doesnt >include locally. If your interested in the Stirling engine development programs, suggest you visit http://www.stirlingengine.com/ That company started here in Wichita by a good friend of mine. I have a couple of the earliest "Coffee Cup Engines". In particular, check out Brent's book offerings at: http://www.stirlingengine.com/ecommerce/category-browse.tcl?category_id=2 and the links cited at: http://www.stirlingengine.com/general-links/ The cable system dog-house is branded "Alpha" which suggests it's the product of The Alpha Group. I wasn't able to find the model of device sitting on my street but here's on example of many products described on their website http://www.alpha.com/us/default.aspx?id=catalog&catId=/477/3482/3357/ The next time our cable guy is in the neighborhood, I'll ask him what he knows about our particular version.

I'm choosing to light my panel and cabin with LEDs that all pass through a pulse-width modulator for dimming. I'd like to hook the Icom's display into the same circuit, but a posting to this list on 2/13/06 indicates that only the positive side of the lighting circuit is exposed to through the connector. My first question is, "Is this correct? There's no easy access to the lighting circuit's ground lead?" (I could put the PWM at the head end of the circuit, but I have some lighted switches that aren't amenable to this.) The second question, "Is a dimmer necessary?" My Icom will be situated on a side panel, situated about 75 degrees from front-center (a delta configuration has it's benefits). Is the light level low enough to not be a bother? -- "Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, with chocolate in one hand and wine in the other, loudly proclaiming 'WOO HOO What a Ride!'" --Unknown ________________________________ Message 8 _____________________________________ Time: 08:47:17 PM PST US From: Ken Subject: Re: AeroElectric-List: Icom A-200 dimming My A-200 has incandescent bulbs with no easy access to the ground as I recall. Think the draw was on order of 60 or 90 ma. I have a two position switch to dim them through a resistor but suspect a dimmer is not really required.

The board is still available at: https://matronics.com/aeroelectric/Catalog/AECcatalog.html The assembly manual and BOM is at: http://www.aeroelectric.com/Catalog/AEC/9009/9009-700J.pdf I'm told that a number of the parts cited from the Digikey catalog have been replaced . . . you'll have to do a bit of substituting. I have a list of the changes somewhere, I'll try to find it an publish it on the List. I don't know when I'll get to updating the BOM . . .
