Some of these features became “standards” for communications receivers while others are only found on the PR and its matching Pre-Selector. Besides its unusual design, the PR has an important place in history relating to radio manufacturing on the West Coast in the s. The PR has always been a favorite of mine, probably because it was the first communication receiver I owned at age fifteen. This write-up includes circuit details, restoration suggestions and a performance report. Before , radio building on the West Coast was uninhibited and pretty much any type of radio could be built and sold without very much interference from the license-holding and patent-owning radio manufacturers located on the East Coast. California was just too far away and their share of the booming radio market didn’t seem to impact the radio-selling profits enough to enlist infringement-busting lawyers to pursue those who were violating patents.
June 20, Without being facetious, why? Do you use different amps for different purposes depending on the input? Do you have a different set of speakers connected to each amp, or do you use the same speakers, connecting and reconnecting them as required?
You dig oddball guitars and strange, rare equipment. Sure, a Fender Telecaster is a great guitar (I have a , and I love it), but there’s something about the weird ones that pulls you in or you wouldn’t be reading this newsletter.
Three generations of Programmable Bricks: In addition, it has a slightly larger screen, more buttons, and it is possible to control the EV3 brick using both iOS and Android devices, as opposed to Android only for the NXT. See this article for a list of technical specifications of both bricks. On first thought, you may wonder why you would need these features. First, the micro SD card slot can be used to add extra storage to the brick by means of a micro SD card.
Additionally, the USB port can be used to link up to four EV3 bricks so that you can control up to 16 motors and 16 sensors on one robot. Although the general user will not notice on the outside, the brick runs a Linux based operating system. Basically, this means that your robot almost resembles a full computer, a bit like the Raspberry Pi! Figure 3 shows the complete family of EV3 electronic components. Complete family of EV3 electronic components not every component is included in each set.
Both versions of the EV3 set contain two Large motors. They are comparable to NXT motors in terms of speed and torque, although their shape is slightly different to make building easier. In addition, both sets have one Medium motor, comparable to the Power Functions Medium motor.

You may also have some insider or technical knowledge that can shed light on the UE22 error and that would be most welcome. This thread will be updated as the information comes in and will be compiled to better understand the problem and find possible solutions. See post and in this thread for the background that identified the cause of UE22 Error. See post 2 where the defective DSP chips are located.
Don’t connect two amps to one doesn’t work that way. You ‘can’ connect two amps up to a dual voice coil sub but it’s a bad bad bad idea. It is possible to hook up more than one amp/sub, but certain things need to happen. I don’t know how to do it but i think your amp need to have phase control, if you know you don’t have that.
Let’s face it; some people go to shows and relate bad venue sound with your band’s talent, regardless of how good your band may really be. House sound systems are usually anything but spectacular, so why not take charge of your own sound with a complete and affordable PA package? Its specially voiced crossover ensures clear separation of frequencies for crisp, full-range reproduction.
A 15″ woofer delivers deep; rumbling low frequencies, while a 7″ x 15″ horn with overload protector produces bright high-end tones. It also features two parallel input jacks, sturdy construction with reinforced corners, and a heavy-duty Tolex covering. The speaker cabinet’s 10″ woofer delivers punchy low frequencies, while a 2″ x 6″ horn produces bright high-end tones.
Installing A Circuit Breaker
So this approach may not work for you. I use 10 AWG for my G, again not for any electrical reason, but for mechanical strength. It will take a lot longer for a buried 10 AWG to corrode through.
In the United States, most electronic devices plug into wall outlets that provide volts of electricity. But large appliances, such as clothes dryers, stoves and air conditioners may require volts.
Dual F25 Well, here’s my deal I am trying desperately to build a theater in the basement of my home. I now have everything other than the screen. Unfortunately, I have had no time for building, so the project is falling behind. A single F25 absolutely blows the SVS away! The difference is incredible.

Email Shares 52 We get a lot of questions on our electric wiring articles from folks tackling electrical projects in their own home. One of the most common and intimidating parts of electrical work is dealing with the main breaker panel. This article provides an overview of a breaker panel. Some jurisdictions require you to be an electrician to perform any electrical work, even in your own home.
Almost all jurisdictions require you to get a permit to complete any substantial electric work beyond simple tasks like replacing receptacles. Electric Breaker Panel Volts and Amps Before we get started on the panel, note that virtually all homes in the United States are wired with amps volt service. For homes equipped with natural gas, propane, or oil heat, amps volts is usually enough to meet electric demands throughout the year.
For homes with an all-electric heat system, amps is the minimum recommended service level. In houses with a heated pool or spa, electric radiant floor heat, etc. The service lines are out of phase with each other, hence how you can get volts of total potential across the two wires. These two service wires come into the panel along with a ground wire usually the ground is a bunch of strands that surround the hot wires. From the main breaker, each of the two service lines connects to one of the power buses on the back of a breaker panel.

Ducting Introduction This page translates the engineering ducting solutions that the experts who guarantee customer air quality use. If you have not already read at least the Home and Medical Risks pages, you should read those pages first to better understand fine dust risks and how poorly most do at providing good protection. The peer reviewed medical research is clear that every fine dust exposure causes a measurable loss of respiratory capacity, some of this loss becomes permanent, the larger and longer the exposure the greater the damage, and in spite of this damage from each exposure being small the damage builds over time to eventually cause asthma, COPD, emphemsia and also worsens other age related diseases often resulting in shortened life spans.
The problems are many. Almost all small shop vacuums, dust collectors, cyclones and air cleaners miss collecting a significant portion of the fine dust made. Worse, most small shop vendors sell too open filters that freely pass the unhealthiest invisible fine dust and they also sell undersized filters which causes these filters to rapidly wear out and pass even more of the finest unhealthiest dust.
OSHA testing shows that with every twenty pounds of sawdust we make enough fine dust to cause 15, typical two-car garage sized shops to fail an EPA air quality test and harm our health. Fine dust lasts nearly forever unless it gets wet. Most vent our dust collection systems inside which allows the fugitive dust that escapes collection to build to dangerously high levels.
Almost all hobbyists and six out of seven professional woodworkers work in small shops that are not government inspected or covered by any standards except what we choose to put in place for ourselves. Most home insurance inspectors, building inspectors and fire marshals will fail almost all small shop dust collection solutions due to serious safety concerns.

Do you need a sub-panel for your basement? Why, and how much will it cost? December 19, by Jason 6 Comments When you’re planning the wiring for you basement keep in mind that you may need to install a sub-panel. How much will it cost? Should you install it yourself?
Wiring in one amplifier can be complicated enough, especially when you’re dealing with a factory car stereo, and the situation just gets more complex when you add multiple amplifiers to the equation. You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra.
Why, for that kind of money, a sane person could buy ten guitars! So, where do you go from here? Here is a group of, in my opinion, seriously undervalued amps. Even the priciest of them are still, in these times of inflated value for anything tube or tweed, well worth the coin. These are relatively simple amps with a very basic control panel Volume and Tone and only Speed for the Tremolo. With a silver grille cloth and the Univox or Lafayette logo, these are good looking, if somewhat aesthetically pedestrian amps.
Very lightweight — super for recording or a small jam where you need a nice bluesy overdrive at low volume. Not the most versatile amp on the list, but a very cool one-trick pony at, often, a great price. Both these amps use the seldom-seen 6MB8 output tubes. They are low powered watts amps, with a great smooth overdrive with crisp highs and woody, warm mids and lows.

Halogen Lighting James It would be nice if you showed an alternative diagram for someone adding a light to an existing circuit. Adam Franz71 I am trying to install a digital timer on my outside garage lights. The timer has Black, White, Green and Red wires. There is only One switch for the outside Garage lights and BOTH wires on the 15a v switch are Black which is unlike the diagram on this page.
The foyer lights and interior garage lights are also on this same circuit. Is it possible to install the timer and if so how should I go about it.
Dear Twitpic Community – thank you for all the wonderful photos you have taken over the years. We have now placed Twitpic in an archived state.
This is where the two pieces meet. The cut is on the weld with little damage or heat to the plates. Although some of the other processes are more efficient, there are some jobs where SMAW is the most practical, like climbing around on a high-rise office tower, shopping centers and large spread-out structures. Skip Weld — A sequence used to control warping distortion. Once on a parking garage there were big beams made of concrete with steel gusset plates on each end to be welded to gusset plates on the columns.
Concrete is never completely cured, it has moisture in it. If you get a cutting torch close to it, or excess heat from welding, it will blow up and send little concrete shrapnel shooting out like a dad gummed fragmentation grenade. If we woulda’ welded those plates solid, it would’ve blown concrete out from around the plate and weakened the connecting points big time. So instead, we skip welded the plates. We’d weld a couple of inches at the top, couple at the center and a couple at the bottom.

Connecting 2 Amps to 1 Sub? I have a friend who use to work in the Best Buy install bay, and he told me it was a bad idea If i connected it all right and set the amps the same, and not too high, wouldn’t it work just like a W amp? Anyone ever done this? It depends on the setup of your sub.
Oct 12, · A sub woofer or two in a vehicle can make the world of difference in listening to music. It is very important to match the RMS of your subs to your amp. You want an amp more powerful than your sub, because you don’t want your sub to : K.
It also has a 5V output, which a few of you might be interested in. This is a perfect supply for the kit. Connecting a 90 ohm power resistor in series with a. Because this unit is external, no AC enters your chassis. This means less potential for humm. Also, because the supply is outside, there are fewer size constraints on selecting your chassis. Finally, the fact that it’s prebuilt gets you up-and running in a shorter amount of time.
