Need a new trim piece for a 6-inch square recessed housing

By njbair

We just bought a property which has an old-style, square recessed light housing in the shower stall. It’s the kind where the trim piece is held in place by springy steel wires which fit into slots inside the housing. Trouble is, I can’t for the life of me find anyone selling these online. I have seen some LED fixtures that seem like they might work, but without being able to see them in person I hesitate to drop $40/ea. on them. Any ideas?

Researchers identify cause of LED 'efficiency droop'

(Phys.org) —Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called “efficiency droop” that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents. Efficiency droop, first reported in 1999, has been a key obstacle in the development of LED lighting for situations, like household lighting, that call for economical sources of versatile and bright light. …read more

Ford's haptic vibrating manual gearshift knob

Filed under:

Vehicles with manual transmissions have been equipped with shift indicators (illuminated or audible) for decades. While some are used to improve performance, most are designed to encourage more fuel-efficient driving. Regardless of the original objective, nearly all drivers become desensitized or learn to ignore the illuminated lights and arrows after just a few short hours behind the wheel.

Enter Zachary Nelson, a recent MIT graduate and an engineer with Ford. Working at the automaker’s Research and Innovation Center in Dearborn, Michigan, Nelson devised a haptic shift knob that vibrates when it’s time to select another gear. “I wanted to create something that expands the car’s capabilities and improves the experience for the driver,” said Nelson. “I decided to use OpenXC to provide a new kind of feedback for the driver through the shift knob.”

The process, greatly simplified, has the vehicle transmitting data wirelessly from its on-board diagnostics (OBD) port using a Bluetooth OpenXC adapter. The knob uses the innards of a Microsoft Xbox 360 controller for vibration. “I decided to have a little fun with it and installed an LED display on top that shows the gear position and colored lights that glow from inside at night similar to the ambient lighting in Mustang,” adds Nelson.

Overall, it’s a rather fascinating idea that you can check out in the video below. The software-driven haptic shift knob allows the driver to keep their eyes on the road, while the vibration can be set to alert one of many different parameters, including optimal fuel efficiency, quickest acceleration, maximum torque, redline shifting and so on, giving it many different uses.

Hi All,
Hoping someone had similar situation:
Size 20k
Salt 3200
Free Chlorine .5
Calcium Hardness 250
Cyanuric Acid 20
Alkalinity 60
pH 7.8
Changed Varistor (as32 2r025) to correct no “generating” or “power” LED(s) issues.
Ran system on Super Chlorinate for 24 hrs and shocked: the results are above.
Also reset Aqua-Rite and perform mild acid wash to T-cell 15.

Realize stabilizer and Alkalinity are low; will correct, but should still get higher chlorine level after 24 hrs…

Any suggestions?

Hello, this is my first post so correct me if this is in the wrong place or format.

I have a ceiling fan that has very dim LED lighting (board? if I can call it that) and I want to swap it out with one that will be bright enough to be a primary light.

I unscrewed the plastic light casing on the bottom and removing the LED light. That’s as far as I’ve got because I am no expert. It looks like its 24V and has a small 2 prong connecter.

So my question is, where can I purchase a new LED light/board that will fit with a ~4.2″ metal plate that holds it to the ceiling fan? With minimal welding or screwing etc. Googling it just caused more confusion.

Quick Spin: 2014 Audi R8 V10 Plus

By Michael Harley

Filed under:
Ignore the naysayers who say the Audi R8 is too refined to be a proper supercar, or that it has begun to show its age – after a few tweaks for the 2014 model year, the automaker’s flagship remains one of my favorite exotics.

Audi has treated all of its R8 models to a host of enhancements for the 2014 model year that include new LED headlights and tail lamps, larger steering wheel-mounted shift paddles, new exhaust finishes, updated alloy wheel designs and fresh exterior colors. However, the most significant news is the arrival of a proper seven-speed S-Tronic dual-clutch automatic transmission (it replaces the six-speed R-Tronic). The rapid-fire gearbox shaves a coupe tenths off the 0-60 sprint and improves fuel economy for both the eight- and ten-cylinder models (thankfully, a traditional six-speed manual is still on the order form).

I recently spent time with the new-for-2014 V10 Plus model, which is only available in a coupe body style. Compared to the standard V10 models, the Plus sheds upwards of 130 pounds thanks to lightweight manual seats (not fitted to my test car), carbon-ceramic brakes, reduced sound bay insulation, a smaller fuel tank and an assortment of carbon-fiber pieces (including side blades, front splitter, rear diffuser and spoiler). But that’s not all, as the V10 Plus also receives a bump in output that pushes its ten-cylinder to an even 550 horsepower.

Driving Notes:

  • My six-foot two-inch frame has always found the R8 Coupe to be very comfortable – a standout in a segment of cramped coupes. The enhanced cabin is nothing short of breathtaking, with beautiful carbon-fiber and aluminum accents, tactile switchgear and a fit-and-finish to rival Rolls-Royce. My Brilliant Red test car was fitted with the optional diamond-stitching full leather package ($6,300) that seems a worthy investment, if just to watch your passenger’s jaws drop when they climbed in.
  • The naturally-aspirated 5.2-liter V10 has been massaged to produce 550 horsepower and 398 pound-feet of torque, a 25 horsepower increase over the standard V10, which Audi says is good for a 3.3-second sprint to 60 mph (with the help of launch control). Nobody will miss the old, sometimes clunky, single-clutch gearbox. The new dual-clutch unit shifted smoothly during normal driving, yet it eagerly cracked off the gears when driven aggressively (don’t waste your time with the console-mounted shifter, as the wheel-mounted paddles are much easier to use). Power at the low end of the tachometer was plenty strong, but the V10 really came to life once it started vigorously spinning. Run it to the 8,500 rpm redline between each shift, and its screaming audio track will remind you why enthusiasts still appreciate fine, naturally aspirated engines.
  • Zipping through the canyon roads in the mountains above Malibu put the R8 V10 Plus right at home. Its mid-engine handling and balance was exceptional. The damping is fixed to a very firm setting, even though lesser R8 models offer a variable magnetic suspension, …read more

Review: Brother's HL-3170CDW color laser-class printer is inexpensive, but graphics are mediocre

You want a color laser printer, but you don’t have a lot of cash. How does $280 sound? That’s the price of the Brother HL-3170CDW, and in exchange it delivers reasonably good prints. Not pristine, evocative color graphics—move on to another printer for that. But good text and decent spot color, it can do, and the toner costs are tolerable as well.

Here’s the real decision: Do you pick this all-around-average machine, or do you pick this other, like-priced color laser, the Dell C1760nw, which has much better color quality—but also much more expensive toner? Or do you think a bit outside of the box and consider a business inkjet, such as the Epson WorkForce WP-4020, which competes head-to-head with both of these lasers on speed, print quality, and features, and whomps them both on cost of consumables? By our reckoning the latter is the best deal, but some people just can’t get laser out of their heads, and they will have to think harder about the tradeoffs.

Bulky profile, basic features, and duplexing

Measuring 16.1 inches wide by 18.3 inches deep by 9.4 inches wide and weighing 39 pounds, the HL-3170CDW is fairly large and beefy for an entry-level, laser-class printer (it uses LED technology to produce basically identical results). The height is due more to the stacked toner/drum system than the bottom-mounted, 250-sheet paper cassette. There’s also a 100-sheet output tray integrated into the top of the unit, and a single-sheet manual feed for envelopes and glossy photo paper. The unit prints automatically in duplex.

When some color printers run low on one color, they will complain, but keep printing. Not so with the HL-3170CDW: It will not print when you run out of any of the four colors. This can be a problem if you really, really need to print something and haven’t any spare toner. Better a warning and a less-than-optimal printout, than no printout at all. Brother needs to rethink this.

DC power circuit

By barclay7568

Folks, I’m brand new here so go easy–I’ve got plenty of questions.

I want to power a 10 X 10 tent canopy at music festivals so we can jam at night with instruments. Power would come from motorhome 12V DC deep cycle batteries. I have ideas of what I want to do but want to know the best way to go about it.

Canopy would be @30 ft from MH. I want to run a direct line from the battery to the canopy, go thru a dimmer, from the dimmer splitting the line to 2 lines, one to each LED strip light. Each LED strip is 24 Watts and they would be 5′ apart. I would run them for 3-5 hours a night. I would like some sort of quick connect/disconnect prior to the dimmer and one after the dimmer. The one after the dimmer would split the line from one to two, one to each light, if they make such a thing. I would also like to make up two additional lines with quick connect/disconnects, each line 10′, that I could add in the event the canopy ends up further away from the MH than 30′.

I have a roll of 12 awg and 18 awg speaker wire, the LED strip lights, the dimmer, and alligator clips to attach to the battery terminals.

I would like to know what the best way to quick connect/disconnect and where to find these parts? Also, does it sound like I’m on the right track on what I want to do?

Thanks for any help–joe

LED appliance bulbs?

By Hi Ho

Hello all. This is my first post in this forum but I have browsed here for a while. I have a Samsung over the range microwave that I actually really like except for one thing. The lights underneath that shine down on the stove are not very bright and produce a tremendous amount of heat. It uses two standard 40w appliance bulbs and I would love to replace them with LED bulbs so that I could leave that light on without wasting so much power and making my house even hotter (no A/C).

This is the type of bulb I want to replace:
Philips 416255 Appliance 40-Watt T8 Intermediate Base Light Bulb – Amazon.com

I have searched and searched for something that would work and unless I’m missing something LED replacement appliance bulbs do not seem to exist. Does anyone know of any warm white LED bulbs that would replace that type of bulb? I have replaced all of the GU10 halogen bulbs in my kitchen with LED equivalents and am very happy with those. I even replaced the small 12v bulb in my refrigerator ice dispenser with a cool looking blue LED. I just can’t imagine that no one is making a bulb that will fit in a microwave.

Chrysler recalls 2013 Ram pickups, 2014 Jeep Grand Cherokee

By Brandon Turkus

2013 Dodge Ram 1500 - front three-quarter view

Filed under:

Chrysler’s spate of successful products is about to be marred by a trio of recalls. The Pentastar is recalling 51,477 Ram trucks and Jeep SUVs. According to the National Highway Traffic Safety Administration, there have been no reported accidents, injuries or deaths related to the affected vehicles.

The largest action covers the Ram 1500, which is seeing 45,961 trucks being recalled. Models built between June 26, 2012 and February 5, 2013 are being recalled due to a potential software issue in the electronic stability control. Apparently, the system can be randomly deactivated upon vehicle startup.

Chrysler is also recalling 4,458 2014 Jeep Grand Cherokee models. Covering everything but the SRT models, the potentially defective SUVs were built between January 14 and March 20, 2013. This recall focuses on “premium headlights,” which means cars equipped with LED running lights. During the switch from the bright daytime running lamp setting to the low-intensity parking light setting, an electrical spike can cause one of the Jeep’s computers to go into a safe mode, turning off the LEDs. This violates Federal Motor Vehicle Safety Standards.

Finally, Chrysler is recalling 1,058 Ram 4500 and 5500 heavy-duty pickups. The action covers vehicles manufactured between January 22 and March 8, 2013 due to an incorrect bolt attaching the track bar to the frame. If the bolt breaks or falls off while driving, drivers may lose control of the vehicle.

Owners of effected models will be notified to report to their dealers for free repairs or retrofits, with all three recalls kicking off in August.

Outdoor LED Lighting for pool patio

By npkr01


I am new to the forum.

I am considering low voltage LED lighting around my pool patio. I found Alliance Outdoor Lighting fixtures on the web along with a few others. There fixtures are brass and seem to be competitively priced. However, I can’t seem to find much on the web about user experience or their quality.

Does anyone know anything about Alliance outdoor fixtures/transformers? Are they of decent quality and reliability?

Any commentary on personal experience or knowledge of this brand would be appreciated.

Thank you

(1) Replacing Existing Light with Cans; (2) Installing New Cans on 1/2 Hot

By entgegnen

First, thanks to those of you on the forum asking questions and providing answers – I’ve been learning a lot and becoming much more familiar with what to think about when doing home improvement projects.

My upcoming project (for which I am seeking advice/guidance) has two parts:

Project Part #1: Remove an existing dome light and install a (non-lighted) ceiling fan and (4) new recessed/canned lights – for Edison style LED bulbs. The room is already wired with (2) switches – one for the yet to be installed fan, and one for the existing dome light. The circuit for the room appears to be 15 amps. I have limited attic access about the ceiling.

From what I can discern, there is an existing “J” box, and installing the (non-lighted) ceiling fan should be relatively straight forward. Where I am confused is the proper method for wiring the (4) new recessed lights. I want them to all turn on/off at the same time, with the existing switch. I am a bit confused as to whether I need to use 14/2 or 14/3. I am also a little confused concerning what order/wiring formation the four cans should be wired – eg. box or zig-zag
(Imagine the finished product will be a square – lights at each vertex and a fan in the middle.)

Project Part #2: Install (2) new canned lights – for Edison style LED bulbs – on an existing switch (different from the two switches previously discussed above) which appears to only control a 1/2 hot outlet. I have limited attic access above the ceiling. This part of the project is also in the same room as the

I suspect I’ll need to run Romex from the existing switch to the new canned lights (Meaning drilling from above, or doing a little patch repair). I also suspect that if I want to make the 1/2 hot “permanently hot” I’ll need to change out the receptacle with one that has not had that copper-tab cut. But again, will I use 14/2 or 14/3 to wire the lights? Is there anything I need to be careful of considering the switch already controls the 1/2 hot? (Aside from turning the power off before I start!)

I am at the very beginning of this project, so I have not taken anything apart yet. I wanted to think it through before I started cutting out holes in the ceiling! 🙂

I’d appreciate any thoughts on issues I should be considering or conditions I should be on the look-out for. Especially I’d appreciate guidance on how I should be wiring the canned lights so I create an appropriate circuit – especially on the 1/2 hot part, which seems like it could be tricky.

Thanks in advance.:D

Overhead Door quit working…

By IDaman

I have an Overhead Door Legacy Model #696CD/B. It has worked flawlessly for the past 6 years. last night we had a thunderstorm, with one bolt of lightning hitting close enough to the house to trip one of my breakers (not the one for the garage door opener).
The door opener stopped working. The power to the motor is on. The two Saf-T-Beam sensor units are receiving power and the lights are constantly on. The wall switch is receiving power, and it is unlocked. The red LED on the back of the unit blinks when the remotes are pushed. The keypad remote is powered and transmitting.
I have unplugged the unit for 20 minutes, hoping for a reset, with no results.
I have not yet opened the case, but I suspect that the capacitor or circuit board might be fried.
Any suggestions on how to proceed will be greatly appreciated. Thanks.

2015 Mercedes-Benz GLA (spy photo)

What It Is: The Mercedes-Benz GLA-class small crossover, spotted wearing its thinnest camo yet. The playful, swoopy lines favored by chief designer Gorden Wagener work well on this compact crossover, but casual observers may have a hard time distinguishing it as a Mercedes without spotting the three-pointed star positioned in the grille. The GLA was previewed by the Concept GLA unveiled at the Shanghai auto show earlier this year, and will lose the massive 20-inch wheels, the recessed door handles, and the laser/LED headlights for production.

3-Way Dimmer Switch Delay – Is it the Dimmer Switch or the Circuit?

By cloves

Hi everyone, I am wiring a 3-way switch and a 3-way dimmer switch, and when I flip the switch there is a delay in the lights turning on. I thought it might be the bulbs so I put cfls, and then even tried incandescent, delay is still there. Eventually the lights will all be dimmable LEDS.

The switch I installed is a Lutron dimmer switch, the other is a regular 3-way switch. Both switches work but there is a delay when the lights turn on, I think a half a second which is noticeable.

Overview of circuit, 15amp which I brought up from the basement into a junction box (14/2). I am going to be using this circuit to power the lights for the hallway, and 2 bedrooms. The lights will all be LED (10 @10watts) and there will be 2 fans (@ 325watts).

Review: A solar home isn't for everyone

As someone who considers himself an environmentalist, I’d love to get a solar array for my home. But I’m finding that it may not make a lot of sense – at least right now. My wife and I drive fairly fuel-efficient cars. Our house is lit almost entirely with compact fluorescent and LED light bulbs. And our entertainment center is connected to a power strip that turns off all of our various game consoles and digital set-top boxes whenever the TV is off.

Official: New Mercedes Unimog debuts to the cheers of little boys everywhere [w/video]

By Jonathon Ramsey

Filed under:

The Mercedes Unimog, the superhero villain of the off-road world that’s just waiting to make the jump to Transformer, has been completely upgraded for its new generation. There are ten models, expanding the range and getting new designations across the traditional all-terrain series and the implement-carrier series. Panoramic cabins get more visibility, multifunction steering wheels and better dash clusters, improved HVAC and a three-mode central tire inflation system. Outside, there are new items like LED headlights and daytime running lamps in the bumper, roof-mounted windshield wipers and a front-camera monitor for the implement carrier.

The new engine lineup is compliant with Euro VI, featuring four- and six-cylinder BlueEfficiency engines putting out anywhere from 156 horsepower to 354 hp. Powerplant placement has also been tweaked, the chassis members getting a revised curve to place the engine a bit further back and lower, maintaining off-road clearance and lowering the Unimog’s center of gravity. The new location of the engine means the cabin has more room, and the wheelbase is shorter. Combined with a higher turning angle, the Unimog has a smaller turning radius than before.

The implement carrier gets what’s called a “synergistic traveling drive,” the bonus being that drivers don’t need to stop in order to use an attachment – a hydrostatic transmission works with the regular manual transmission at up to 31 kilometers per hour for seamless switching.

Those are just a tiny number of the changes in the new Unimogs. You can find out enough about them in the two videos and three press releases below to become a certified dealer.
