Mr.Tim's 15x27 Theater - Page 9

post #241 of 595

That's what happens when you don't feed the dog Tim wink.gif

 

That or the wife trained the dog to seek out theater goodies you are trying to sneak into the house without her knowing about it.

Wow, Tim! You've had a rough day. Sorry to hear about the column and the T-stat. Are you planning to make them replace the Tstat? You've got it on video that they assaulted your dog and the Tstat smile.gif

Hey guys,

Sorry, wasn't notified of replies. I was going to call the Postmaster and complain, but I decided I would talk to the guy tomorrow (I assume the weekend postman is the same every weekend) and see what his problem is. Our weekday postman is awesome, but he only does Mon-Fri. As I understand it, you have to work part-time filling in on weekends and such before you can get a full-time job with USPS. I figure with weekend delivery being on the chopping block he is probably going to lose his job soon.. which sucks for anybody.. but especially sucks for him since he's been working the shifts nobody else wants in the hopes of getting a full time job. I hope a face-to-face will resolve the situation and let him keep his job for as long as he can.

It's not the end of the world.. It kind of made up my mind about painting it black.. I'll just put some epoxy in the tooth marks, sand and paint.

I started prepping for painting the walls.. took all the masking down off the walls and now I'm masking the opposite.. covering up the wainscoting and columns. I sanded some of the walls and ceiling but working over my head with a sander is definitely not something I'm used to. I can only do about 100sf before I have to stop.

I put some of the black screwless cover plates on and I gotta say it looks awesome against the satin black paneling. I also got a few coats of black paint on the central vac outlet.

Just bought two more 15" subs... will put them on the shelf for subwooferage to be built at a later date.

Need to pick up some 3/8" ply to cut for the fabric panels in my columns.. I think I may have to order fabric soon... hallelujah!

You must have either shoulders of steel or an exceptionally light-weight sander. 100 square feet over my head would kill me. Keep it up! (ha ha!)

That's what happens when you throw a bone colored, well, ...anything, at a dog.
That epoxy and sanding idea is brilliant tho.
So simple it never would've occurred to me.
I really hope we get to see the finished repair.

Just a pole sander with a sanding screen to knock any blobs off. Very lightweight.. but still very tedious.

I will definitely show a pic. THe two-part epoxy has to be mixed in somewhat of a quantity.. I am trying to figure out what I will do with the other 95% of the mix besides throw it away.

That's easy! Make a bone with it! Then give it to the mailman so he can use it as a decoy so he won't have to deliver your stuff like a softball pitcher! biggrin.gif

I decided last weekend that today would be painting day. I hate painting. I did everything I could to avoid it.


I fixed the brakes in my truck:
IMG_1639.JPG



I started fixing the thermostat that was chewed by the dog (JB Weld):
IMG_1638.JPG



I hooked up the RS-232 to the existing basement thermostat (iRule, here I come):
IMG_1640.JPG



I figured out where this wire goes (to the attic, unfortunately):
IMG_1641.JPG



I also learned a few things.



I learned that the addressable smoke alarm I had been saving for the theater doesn't exist. I was going to paint it black (still better than painting a ceiling), but apparently there is no such smoke detector. I looked where I thought I had it.. found a keypad, water sensor, glass break sensor and extra alarm. But no smoke detector. :sigh:


I learned that the wire from the equipment closet from the boiler controls doesn't exist. That's a problem, since I ran the wire from my theater thermostat to the equipment closet.


I learned that I have 8 cables for LED lighting terminated at the transformer, but only 7 cables in the soffits.



Having put painting off for as long as I could...




I primed all the bare joint compound:
IMG_1643.JPG


And cut in all the black on the ceiling....

Wow, you've learned a lot today smile.gif Doesn't sound like a lot of good news, though. Missing wires is always a hassle. Do you have a tic tracer to try and find where the missing wires are?

Keep up the good work! All that painting will be worth it in the end. If nothing else, you're just checking off the to-do's before you get to sit back and enjoy your theater.

Oooh - 8 at the box, 7 at the soffit - ...fun times ahead.

No, a toner is not something I have in my arsenal. I know where the wire should be, so hopefully I can cut a small hole and find it.

In other news.. the ceiling is now BLACK. First coat DONE. Second coat tomorrow!

Did you spray or roll the ceiling?

I rolled the ceiling. I never sprayed a wall with latex.. and I didn't want to try on the ceiling. I was afraid that if I screwed it up.. it would be catastrophic.



Here's what it looks like after I sanded the first coat:
IMG_1647.JPG


You can see how even at this point a little sanding is a good thing. You're not going to make up for a lack of prep work on the spackle, primer, or first coat, but if you sand after every coat you will have a nice finish.



Here's another little tidbit:
IMG_1648.JPG


At the very least, hitting the paint lightly with some sanding screen will knock off all the little snots you get if something gets in the paint. Now, you shouldn't have a lot (if you see a lot of little white specks, you need to reevaluate your painting technique), but it will take care of the errant little snot. This is from when the roller hit the smoke alarm wire, the wire hit the ceiling, and must have left a chunk of spackle.

For most situations I guess you don't have to go crazy. High end painters will sand like this. Average painters just put on coat after coat.

The litmus test is when you turn on your cove light.

Nice job! Your attention to even the smallest of details will no doubt pay off in the end. Great looking space you have going there...

Thanks smile.gif

In other news, I got a letter from the Postmaster apologizing for the incident with the parcel. I just hope they don't start leaving call tags rather than actually delivering packages. I know ifit;s during the week my regular postman will do the same awesome job he always does. I gotta keep my eyes on those weekend guys, unfortunately.

Been doing a little painting in the evenings, but don't want to commit to rolling out the wall until I have the entire day to work on them. Painted the chewed up thermostat black, it came out really good considering what I had to work with.

Here's the color combo for the walls:

I think it will work out nicely. The brown will probably be a tad darker when the second coat goes on.



Oh, and this:

No woofing until it gets warmer outside. I'm jealous of you guys that have garages!

I am going to get everything done in the theater that I possibly can then I have an F-20, two THT's, three Stens and four Sten II's to build. I'm seriously considering getting the Sten baffles from Erich.. that's a lot of speakers to route.

On my short list:
-finish the paint
-cut all the 3/8 plywood inserts for the fabric columns
-terminate all the low voltage wiring
-cut and install the blocking for the crown; install crown
-run new wire for thermostat

A little bit of an update.. I jumped back on the electric, trying to finish the step lighting/projector power inlet/stage lighting

IMG_1655.JPG


Here you can see the step light that was formed into the concrete getting picked up by the first box.. the second box will have the power inlet for the PJ... the conduit continues on to behind the screen wall. Not sure if I am going to do the lighting behind the screen.. but it's easier to run the wire now.



A little tip when you need to have boxes next to each other:

IMG_1653.JPG


What I like to do is use a 1/2" threaded union and two 1/2" chase nipples. You get a nice connection (especially if you are doing multiples.. box spacing is the same) and the chase nipple is flared so there's no sharp edges.



I also got a little sidetracked on this:

IMG_1654.JPG

That's my old Yamaha RX-V880 receiver. No HDMI and only Dolby Pro Logic.. but it's got pre-ins so I will probably repurpose it for something. I took it out of service a few years ago.. finally got around to tearing it down. Two of the transistors are blown. I was able to order original manufacturer replacements (about $8 for what I needed.. but I ordered a few extras).

In other news I'll be in the Boston area tomorrow with the day pretty much to myself.. If anybody else is in the area, send me a PM.

Picked up some 2x4 to rip as backers for the crown molding. I have the molding catalog from my building supplier.. I quickly realized I need to have the crown in hand before ripping the strips. There are so many styles, some with different angles. Looks like I'll be picking up crown molding tomorrow..

Replaced the transistors in the receiver.. Waiting for a dual emitter resistor to arrive (actually, 6 of them.. never pays to buy just 1).. Everything else checks out, so hopefully I didn't miss anything and it will come out of protect mode.

Found that the pencil for my new CCI 60 watt soldering station was damaged (replaced a WES51 which was a nice station.. but I dropped it). Emailed the guys over at Circuit Specialists and they are sending out a new pencil today, no need to return the old one. I've dealt with them for years (never had a damaged item before), and was glad to see their customer service is still top notch.

Getting to the point where I am going to have to order fabric. I am trying to hold off until the last moment, as I don't want to damage it.

I am going to have to find some 2" thick material for absorbers soon..

A dual emitter resistor you say? I haven't run across one of those before. smile.gif

When you troubleshoot something like this, do you look for the components that the magic smoke has been let out of? Outside of that, do you need a schematic to work from?

Me neither. I've used resistor arrays before, but the dual emitter is new on me. You could use two independent resistors, so I don't understand the attraction of combining them (maybe to save a penny?), but then again I'm no EE.

Unfortunately, there were no signs of magic smoke. Bad caps are always an easy fix, but the caps look fine. So yes, you need a schematic. The service manual will give you some very basic instructions on troubleshooting. It also gives you a detailed schematic and block diagram. It tells you what current and voltage should be at specific points. Once you identify areas that are out of spec you can trace it back to the parts that are bad.

Of course that requires a bit of knowledge on what the parts actually do. I traced the problems back to the transistors and was able to tell they were fried with my DMM. Once I got those done and it didn't come out of protect, I started checking the resistors (should have done that originally.. oh well) and found one of them was definitely sizzled.

ps- those are the big white rectangles on either side of the giant caps

It sounds like a dual emitter transistor. I know you can bias a transistor so that it acts like a resistor (same voltage/current relationship). I'm getting a bit out of realm of expertise, but IIRC the primary benefit is size. On a PCB, resistors take up a lot of space, so it's often more economical to use a transistor instead. The picture above certainly looks like a resistor, though. Interesting. I'll have to add this to my ever growing list of things I want to learn more about smile.gif

Where do you get the service manual from? I think that's probably the piece of the puzzle I've been missing.

They are resistors (metal plate).. there's no flow control. Here's the datasheet. It's a very obscure animal. Relatively hard to find. I have to think that's do in part to the fact that you could just use two separate resistors.

As for service manuals, I just googled for "RX-V880 Service Manual" and found it in pdf format.
