What DIY projects have you been thinking about?

I am in the first stages of building a diy projector with a 10,000-20,000 hour bulb so I can watch a 100 inch tv all the time.

Are you using plans or Swag (Scientific Wild A$$ed Guess) method? This could be a good project.

What bulb and source are you going to use lou? I thought about making one that used a 7" lcd with a metal halide bulb but decided not to because a lot of the parts are hard to find in canada.

I just installed a fan in my desk.
Here is my story: my computer desk has a compartment in it where my computer sits. Since it is in a mostly enclosed location, it gets pretty warm. So I installed a fan in the side of the desk with a switch on the front so I can vent the desk. It is pretty cool if I must say so myself.

I am finishing up the design of a SDA arrangement with 8 stereo, and 8 dimensional woofers, 2 tweeters, and 4 PR's per cabinet. both arrays will be divided into separate chambers so I can run in pure stereo mode (just the 8 stereo woofers) for movies. I am going to electronically control the SDA affect via combining stereo, out of phase l/r swap, and crossover frequencies with tri amplification per speakers. I may also work into the electronics being able to send just the LFE to the dimensional drivers when in "movie mode".

I can't wait to see the results. I am thinking of doing mine in cherry or mahogany. I'll need 3 sheets to do the job so I can't go as fancy as yours. Keep us updated

ben62670,
When you finish your speakers, could you post some pics? I am very interested in your custom design.

Will do. I have done 2 different cabinets so far. They have been learning experiences. I am really taking the time to get the plans done right for this project, and have had help from some fellow Polkies, and CS on this project. I am still in need of a few more drivers, but I am well on my way to getting the actual build rolling. These suckers are going to be about 7 feet tall, 2 feet wide, and a little deeper than the originals. I expect them to weigh around 300 lbs when finished:eek: . With all my back, and neck injury's it makes it hard to do these by myself. In a couple weeks my friend should have the time to help me make some cuts, and assist with the assembly.

Here are some picture of my in-desk fan install. It's not pretty, but it's inside the foot well of my desk, so it's not in public view anyway. It's a pretty cool idea, I wanted a fun but short project, and the whole thing only cost my $6 anyway.

Looks like quite a project. That African paduak will look great against the black lacquer. Keep us updated, I'd love to follow along so I have something to go on when/if I decide to redo my 2B's.

On my list:
- sell current AV stand, move bedroom stand to 2-channel rig, get a cabinet for bedroom gear
- replace speaker feet with some cool brass feet.
- replace tweeters in my RT600s with cash I get from
- replace the LCD on my digital camera that I've managed to break twice in the last two months.
- sell all my random audio gear as my 2-channel rig is finished, gear-wise.
- move kitchen table out as it's getting in the way of my kitchenette 2-channel system. Eat on the floor.

1. rebuild crossovers for sda2's(when I get the money)
2. Build a pr sub ""
3. Center channel using 4 mw(with bucking magnets) & tweet from crs
4. Replace poly switches on sda's(which I ordered today)
5. Build custom enclosures for my van for my component set.
6. Build a tube amp.< most likely won't happen, after time involved would be cheaper to just buy 1.
I can go on and on.

I have built a sonosub. If you need any help let me know. If you use the sonosub.exe program it does not calculate the boxes very well. I recommend WinISD instead to get the volume right, and then use sonosub.exe to build the tube right. I learned the hard way:o

Three sets of SDA crossovers. All with Sonicaps and Mills.

Bass traps and a custom sub enclosure.

What haven't you built?;)

I followed the thread where you built those big-**** SDA mofos.:eek: :eek: :eek: :eek: :eek: :eek: :eek:

Seriously, it could be a year or more before I can get started on that project, but I sure appreciate the offer of advice and will definitely take you up on it when the time comes.

Did you (or anyone else, for that matter) ever consider suspending the sonosub from the ceiling? There was another thread that brought up the value of raising a sub off the floor, and suspending it would solve the problem of instability of a big, tall sonosub. Finding the best spot could be a challenge, tho.

Suspending the sub would be a good idea. It would help decouple it from the floor for sure that way. I could do that with my homebrew SDA's too, but I would need a houst, or come along for that. You have me thinking;)

I need to do a couple of things anyways like
Acoustic treatment
audio rack
fine tune tweeters
fix Adcom GFA-585
maybe someday clean room:o

I am currently working on my daylight basements. ITs about 700 AQ/FT. On side will be my HT. Next week I get my dedicated circuits run down there. In 2 weeks Ill put up the insulation and then Ill have my drywaller come in. By the end of summer I hope its done. It'll them move my HT down there and install a 1080P front projector.

OK lets see here
1. build either a push/push isobaric 18" enclosure or two simple ported or vented. Always wanted to do an isobaric but its hard to give and 18" for that. under the stairs where my velo 15 is at now. ( and slide this all by the wife, the construction that is minor wall trimmings involved to put 2 boxes. with one isobaric I dont have to change the hole for it. but man when it hits your gonna notice it.
2. Vent my entertainment center at the top with a couple fans , Ive already completed the shelves being drilled for ventillation, now the wife wants to finnaly put glass in the doors,

3. I wanna start my 400 horse 350 so I can drop it in my RX-7 and go play with the little rice burners again.....hehehehe wanna play lil boy?

I saw a nice V8 conversion that used a 302. It was done professionally. Has to be a ton of fun. Mine was a ported 12a with a Delorto side draft, and it hauled butt. It was just over 200hp with a 12,500 redline, and a Center Force II clutch. It did a calculated 145 of a flat road. Fun to do nice tight donuts in. All racing beat parts.

Deadof_knight

Ben you have to be joking , man even tho I have never met you we would have to had to been friends if we had. I just sold my rotary and tranny . Local porta rican did my motor 13b ported all race springs and seals and some rican know how. The motor was set up for side drafts and it performed great, but for what Im looking for I could have 400 ft lbs of torque for the same money. Thats what sold me especially after seeing the weight distrobution didnt get thrown out the window , Ive got the block the forged crank ,the rods , the roller lifters and spyder kit. eyeing a t-56 now , probally go hypertetic, and afr heads ,something streetable cam whise.

I grew up in a small town called Willimantic next to Uconn in Storrs. It used to be the biggest thread mill in the US. A bunch of Puerto Ricans moved there because they didn't need to speak English. So I saw plenty of Celicas, and RX7's, and RX2's in my days. I have never done donuts in any vehicle like an RX7. Those things can do such a tight donuts it feels like the Tea Cup ride in Disney World. I used to do them till the smoke was so thick I couldn't see where i was going. My friend and I used to go out into farm country, and find the steepest hills we could find, get up to the top, go in reverse as fast as I could, push in the clutch to go even faster, then I would redline it and dump the clutch in second gear. The thing would be going back wards so fast we could see the J strips in front of us. Ah to be young and dumb. That little 1198cc engine was the little engine that could. They are real tough, but extended high speed over 130 would prematurely wear out the output bushing at the rear of the tranny. Yeah we would have had a blast. I would like to do a dune buggy with one of those engines. No valve train to worry about. Only three major moving parts. I allways wanted to do the Marriah wide bodykit. I saw one, and it lookedlike an imsa car. Are you Puerto Rican?

THE HOUSE SOLD!!! Well, pending the buyer getting their financing and all, but we are supposed to close on July 27. So, I guess I better start working on the wiring diagrams.

Anyone have any suggestions for electrical isolation of the Home Theater? Put all the components on the same breaker? 20 amp circuit enough, or should I make them put 30? I may at some point go with a pre- and separate amps, but for the time being the onkyo will be it. The parts--
Onkyo HT-R530 (110 w/ch 8 ohms, it is the AVR that comes in the HTS780 HTIB)
Polk CS 245i center
Polk R300's front
Polk R150's surrounds and rear surrounds
InFocus SP4805 with 80" screen
Gonna add that sonosub as soon as I can!;)

Really want to avoid those ground loops!:mad:
