Although I understand the LE is the heart of the Aleph, how about a bezel option (Aleph-2) that will accept a sandwich/module/drop-in in lieu of the LE? It would make the Aleph design even more capable of expansion.

Second the vote!! /ubbthreads/images/graemlins/thumbsup.gif /ubbthreads/images/graemlins/paypal.gif /ubbthreads/images/graemlins/thumbsup.gif
 
Wouldn't that result in having to make two different type of Aleph heads? One with the screw threading for the normal LE or any type of sandwich and E-screw you can buy from Wayne, and one without that which you could just put the sandwich into, minus that same screw (which also acts as a heatsink)?

That could be problematic - as that means that not all the parts are interchangeable, which is (IMO) one of the strengths of an Aleph system - any part for one Aleph will go onto another.
 
A sleeve would probably present fewer issues with manufacturing, and give your sandwich or drop-in sufficient contact with the bezel to allow thermal transfer. Another benefit to a 'snap on' or 'screw in' sleeve for a module like what you mentioned would possibly to allow you to put something like that into an Aleph 3 or Aleph 1 head....

But again, I'm still wondering as to how well a snap-on sleeve would transfer heat, since part of the E-screw's function is to act as a sink... which usually means filling said can with thermal epoxy. In which case, you've made an LE out of the bugger. An LE that can change sandwiches would be an unusual challenge, however.
 
It might be possible to make a special "empty" E-screw that behaves just like a LE but houses interchangeable sammies ... but tzhat's just a wild guess.
I wanted something like that some time ago but of course Don said some wise words why this wasn't a good idea. I am sure he will chime in say "no" himself /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif

I don't have an E-Screw on hand, but I did some fiddling around with a sandwich and the old E-Cans while I was building my E-Pill. Since the sandwiches are built around the same 0.55" diameter converter boards, they slide right into the E-Can. However, they're too short, with the base of the emitter roughly flush with the top of the E-Can (basically missing the thickness of the E-Sink).

I assume there's a similar problem with the tolerances of the E-Screw, where the emitter will be set back too far from the reflector or the ES-Can will be unable to contact the body tube. This problem (assuming it exists) can be circumvented by spacing the sandwich forward relative to the E-Screw and extending the positive battery contact.

Finally, the sandwich needs to be held from going forward, and the system cannot interfere with the reflector/E-Screw contact. I think the Aleph 2 reflector rests directly on the emitter, so it wouldn't be a problem.

Hmmm. Now I think that a system is possible, though not necessarily a good idea. The housing is roughly an assembled E-Screw bored from the back to house the sandwich. The sandwich is inserted from the back, and a thin lip (think bottom of E-Can) holds it from going forward.
 
My initial thoughts concur with Flatscan. I suspect that a threaded bushing aw well as an anode contact extender could be designed to host the sandwiches in the Aleph heads. One issue that is not ideal is the additional thermal bridges resulting. I can add this idea to the list of other ideas that hasn't been attended to recently! /ubbthreads/images/graemlins/banghead.gif /ubbthreads/images/graemlins/tongue.gif

EDIT: I wold like to point out that going to the modular Aleph system itself has been a step in the wrong direction in terms of thermal relief. The McLux, PR and PR-T heads have the best heat sink format around, IMHO. In messing with some prototypes using deper reflectors, I realized that the assembly of a head based on an integral bulkhead would start to become problematic. I also felt that the thermal compromise of the LE was reasonable and worth making for the obvious modularity it allowed. This idea here is now a module within a module and both thermal as well as electrical barriers are compounded.
 
Hi guys,
I couldn't help myself as I have been wanting to do somethinf *different* for some time now and Ray's idea took hold and I knew it could be a quick exploration. /ubbthreads/images/graemlins/blush.gif

Samich-LE.jpg


As it turns out, the samich/ LE adapter is very straight forward and the axial stack of components is functional with no real issues. The only thing lacking in the prototype I show above is a groove in the rear of the adapter for samich retention. This LE works fine with all three Aleph heads.

I guess the question now is "Yeah, So?" /ubbthreads/images/graemlins/nana.gif
 
Not quite sure what this gains us. Ya gotta buy *something* to make light the screws in there. Is this just because there are sammiches out there in the wild already?

The biggest problem I see is that pesky thermal path!

Pretty slick, though Don! /ubbthreads/images/graemlins/thumbsup.gif
 
Darell ... might help for more modularity if I can switch sammies from my Firefly or MiniMag (not that I had one) into my Alephs ... and be it only to test how a certain combo would work, e.g. a LD in a McR-20.

Not all of us have this stuff in abundance /ubbthreads/images/graemlins/nana.gif /ubbthreads/images/graemlins/grin.gif

Dear McGizmo

I have another Aleph suggestion- how about a twistie on/off switch if that would knock a little off the overall length?
I still haven't got the Aleph I ordered from SShop but am already thinking of ordering extra bits...
 
Awesome Don. Darell, I think this allows folks with sammies running around the optin to use the Aleph as the host for them. I think it gives the Aleph even more appeal than what it has now and since it doesn't alter the base parts/pieces, it's even nicer.

Oh yea......... let me know when I can get a few.
 
Very nice, and I would like to second TIN in making the adapter available.
I also have wanted to put a sandwich into my Aleph, and have tried a few things with e-cans without much success (I was looking for a metal washer to fit between the head and the e-can fitted with a sandwich).
I have quite a few sandwiches, I enjoyed building them to find out that I have many more than the lights to fit them in /ubbthreads/images/graemlins/crackup.gif
