  3. Ikea Speaker?

    in Speakers

    Posted

    This is a spin-off of another thread:


     

    Why not just find a box at IKEA and put speaker in there? If you don't mind, I won't soil my sheets over your design, but I am sure the speaker could be voiced to sound very "audiophile".

     
    I have long wondered why IKEA does not make flat-pack speakers. 
     
    Either a simple, but relatively large (larger than what you could conveniently load into a very small car anyways) single driver or 2-way speaker in a rectangular box (maybe with a port?) OR a crazy-super-sexxy single driver folded horn. 

     

    I wonder if the market demand for a nicer speaker is just too small :(

    I wonder how it would do with a balanced tube output stage. Circuit ideas anyone?

     

    The "Broskie cathode follower" lends its self well to balanced drive.

    Build 2, and hook them up out of phase.

    You could also build a simple long-tail-pair output stage with a robust small-signal tube (5687, 6h30, etc) and transformer couple to the output. If you want to get fancy (and why not?) use a blumlein garter instead of a LTP.

    Tritium is a gas. It is only found in those little glass vials. 

     

    You guys are talking about various luminous paints, which have NO tritium. Radium - perhaps. Various phosphors, absolutely. Other stuff - most likely. 

     

    Radioactive paints were pretty awesome. Cheap, bright, and reliable. That got banned because the paints were hazardous to the people who had to paint the faces. The radiation is contained by the watch case & crystal so no danger to the wearer. 

    Then we had Non-radioactive luminous-paints which range from awful to "still not as good as radioactive paint."  

    Then someone figured out how to make tritium lights which gets you the awesomeness of radiation, with no exposure factor to the watchmakers.

     

    *My timeline may be slightly off for the invention of tritium lights - they were not used in watches until after the prohibition of radioactive paint.

    I emailed the people with the watchmaking class to reserve a spot at the May 18 class, and heard back that they are pretty much fuller than full - BUT they are switching to weekly classes! 

     

    It looks like they are changing from a "reserve a specific time" to simply "first in E-line first in available class", but hopefully I get in soon regardless. 

     

    I wonder if they let you take pictures?

    Thanks ... that's a relief.  

     

    I still haven't heard back from the guy and I've a developing  suspicion that I won't. When I made the purchase, I used PayPal (which is linked to my bank account) and I was curious as to why he was so adamant about "letting the funds clear" before shipping me the amp (I mean, once the PayPal payment is made, even if it pulls from your bank account, I'm pretty sure that's the same as guaranteeing the funds are in route).

     

    Anyway, bad vibe all the way around the more I gestate.

     

    And re: the work to make things right with the amp?

     

    I would never even *dream* of touching the mod reversal; I have zero skillz in that arena and wouldn't want to use this as a springboard.

     

    Can any of you recommend somebody in the USA that I could ship the amp to in order to have said work done? If I end up stuck with it, then this would be my preferred course.  And if the dude refuses a deal reversal, I'll at least see if I can get him to cover shipping/parts/labor for said work if I'm able to find somebody stateside who can do it.

     

    Thanks again for the replies ...

     

    Contact paypal.

    And tell Jude.

    One time, a long time ago I used to smoke and work retail.

    There was this cashier who would smoke like 5 packs of cigarettes a day. He was NOTORIOUS for bumming cigarettes off of others. I'm not saying I'm a saint, and I eventually took to buying PACKS of cigarettes for others to hold (no joke) to stop but this guy was a menace.

    So, at this job you got 2 10-minute breaks, one before lunch, one after. Pretty standard, I guess. This guy, the cashier would show up to work early, CHAINSMOKE like 4 or 5 cigarettes, and then take the absolute first 10-minute break. He would regularly smoke 2 cigarettes in 10 min, and could probably do 3 if nobody was looking. Anything he could do to get another cigarette - he was on it. Need someone to gather shopping carts when its like 50 degrees below zero, and windy as fuck - he would be happy to go.

    Anyways. One day, I'm out there having my lunch, sitting on a fire-exit, having a Marlboro Red cigarette and lunch with one of my other co-workers.

    And, wouldn't you know it but this guy walks over and asks "what you smkoking" Just like that while holding a pack of (some green who knows whats) and we tell him "Marlboro Reds" to which he replies, in one single breath: "Uggh, Reds? Those are disgusting! Can I have one?"

    Yea, we gave him a cigarette.

    The story above about someone telling you your shit is fake, and in the same breath asking to buy is made me think of this. I apologize for not being as good of a story teller as Alex.

    That's a pretty expensive conversion. I thought there was a company that modified that filter for like $250 or something. 

     

    D810a is $500 more than the D810 (MSRP)

     

    NOBODY in Japan has a very good record for getting pro-level cameras right enough that they don't need a recall or 2, in the last few releases anyways.

     

    Having a warranty is probably worth $250 this early in the game. 

     

    I'm curious if Nikon will ever make a B&W version. I mean, I would much rather have a GR-monochrom, but I imagine that a D810-monochrom would be very practical for micro-photography and other non-color-sensitive documentation. 

  25. Is it possible to remove a grado driver and leave the cup intact?

    in Headphones

    Posted

    I have removed SR-60 drivers, but destroyed parts of the outer housing in the process. Have you ever seen someone have a cast removed? Cut a few slits (not quite as deep as the driver) along the shell, and then it just peels off. A little glue must be dealt with, but it is easy enough. 

     

    I have also removed RS-2 drivers, without destroying housing or driver (woot!) but it was a LOT of work. This is harder. You need to get a tool between the wood and the driver, and work it around. Big pain in the butt. I assume a similar technique could be used with the plastic grados. 

     

    Whatever you do, DO NOT use acetone or any other solvent. There is No telling what that will dissolve.
