Where Should I Place the Series Termination Resistor for AVSBus?


Where Should I Place the Series Termination Resistor for AVSBus? 1

You can add a series resistor at the sending end of the clock in order to control reflections ut, you do need to route the PCB track at an imedance that somewhat matches the series resistor.Or, you can use a arallel resistor at the receiving end: -Given that a driver may not e ale to suly enough current for (say) a 50 ohm termination, a lot of folk ot for the series arrangement. There is a further otion - see icture (d) elow: -It works y dealing with the high frequency content of the clock ulses (i.e. the harmonics) and terminating them correctly. This means that "C" can e quite low (maye 100 F or less) and DC conditions are unaffected.At 25 MHz, you might e interested in ensuring that the 7th harmonic is roerly catered for i.e. u to 175 MHz. At this frequency, the wavelength is aout 1.7 metres and usually, engineers say that if track lengths are less than one tenth the wavelength, then terminators can e avoided. This means tracks can e uto 17 cm long however, electrical signals travel at aout 0.

6 the seed of light so, this lowers that track length to aout 10 cm

Physics Engine with Fixed-Point Positions closedI've never heard of one.And there are reasons why noody does it that way.First, numerically-intense comutations moved to floating oint decades ago ecause of the amount of headache involved in keeing track of the decimal oint across multilications, divisions, and exonentiations. The moment you hit transcendental functions (sin, cos, ex), you die horrily.Second, one light-year is aout 63000 AU, so your "universe" is 15 of a light-year across. Given that Alha Centauri is 4.3 light-years from Sol, your Universe is limited to one (1) solar system. AT THE MOMENT, it is summer on Pluto, meaning that it is just inside Netune's orit, and so the whole asic Solar system is 60 AU across (30 AU to Netune's orit, x 2).

What are you tired of explaining to people when it comes to electricians?

We used to operate a lighting store. It was difficult to get electricians to come to people's house and install things. Most electricians don't want to do that. People don't expect to pay a lot or they start to argue. I had to explain on one of my cadre of electricians, never to argue the price. He would simply hang up.I had to explain to people that there were different levels of electricians. Less skilled ones tend to do new house construction wiring which is repetitive. More skilled electricians migrate to industrial or commercial work. Highly skilled electricians tend to avoid residential installations.one funny story, was where a homeowner was returning a flexible track light. He said that that his electrician said it was no good. However at exactly the same time an electrician who worked at a local nuclear power plant, wanted to buy the same product. So I credited the homeowner and immediately sold it to the electrician. The homeowner stood there amazed. I suggested that the homeowner needs a better electrician.summary. It is hard to get electricians to do installations and it is really hard to get highly skilled ones.

Solar panel set rotation: How to achieve both vertical and horizontal rotation?

Your question is very broad... what have you tried already? SE can help with specific issues, but not design an entire sun tracking system.However, a simple google for "sun tracker DIY" should give you some ideas. 50k4's suggested link is a very good example of a DIY sun tracking system.

Basically you need to track the Sun, on a daily basis, throughout the year. So a mechanical system with 1 or 2 DOF (degree of freedom) is required to tilt the panels, along with a mechanism to track the Sun.TiltThere are two types of tilt required - vertical and horizontal:How you mount the panels on to the servos is up to you, either:Remember the larger the number of panels in the array (2x2, 3x3, 4x4.

..), the heavier the array will become, the greater its mechanical inertia and the larger the required actuator will be. You could use one actuator for each panel, but then the maintenance required will be greater, as there are more servos to maintain. Also, from a cost perspective, is one big actuator cheaper than 9, or 16, smaller servos?TrackingThere are a number of ways to actually track the Sun, to keep the panels facing the Sun, including:.

I have little lag on Offline Games

Do you get this on any other game? Do you delete your mail from your inbox and have the same on lots of accounts?

turn off PS3 so the red light is on.

Hold and keep holding the power button. The console will turn on, and eventually turn off again.

Once off, with the red light on again, press and hold the power button. You will hear one beep, another single beep after that, and then two beeps in a row. After the two beeps, let go of the power button so it doesn't turn off again and you'll end up in the system recovery menu. From here there are a few options. Now this is important, DO NOT CLICK ON 'RESTORE PS3'. That will wipe the HDD clean. You don't want that...

What you want is the other two options, 'restore ps3 database' and 'restore ps3 file system'.

These two options will not delete any content on your HDD, but it will nuke any music playlists you have, and if you edited track information on any mp3s, say you renamed them all to something less ambigous than "track 01", the names and other altered data will revert.

How to keep a tray horizontal when moving around a closed, vertical track?

Image in my mind: The track is on a wall, with the trays being perpendicular from the wall. The track is rectangular (with rounded corners obviously). Solution 1:

If the things that the trays are holding are relatively light (to the tray/shelf), or if its feasible to perfectly balance the load on each tray, then you could just use gravity. You could attach the tray to the track carriage (for lack of a better word) via a bearing, and then just ensure that the CoG of the traycontents is well below the pivot point (where the bearing is).Solution 2:

Have an additional track/slot that controls the angular position of the tray (by it's position, so it would not just 'follow' the other tracks). It would probably need to be a slot, and the 'track' would probably need to be redesigned as a slotted/indented track as well that was of greater depth than your angular-controlling slot so that the angular-control-slot could pass over the normal slots/track. It would be an idea to offset the arm by something other than the depicted offset (let's call it 90 degrees) as then the two tracks would overlap less.

How do you manage / collaborate on a project in Unreal with Developers and Designers?

Unreal has source control built in, I recommend checking out git, and setting up a local git server to track the users and their changes. Good practice includes working in a separate branch per sub project. for example. If I am working on a blueprint script for a light switch I would create a branch called light switch, and after it has been tested I can merge the branch into the main branch. This prevents issues that can break the entire project until they are resolved or files from being inadvertently deleted. As for partitioning the project, Take the overall project, and decide what components need to be built or designed, assign those to a group, then split those down into tasks. assign each group member a task based on their skills. Slack can help in organizing communication within each group, and overall. I recommend no more than having meetings 3 times a week. This helps the programmers a lot. mainly due to the common requirement of maintaining the overall code they are working on in their head until it is complete in code.

Be sure that the code is properly commented. I can't stress how important that is especially in large projects

What is a good approach to detecting distance and speed in model railroads?

I would start with the optical interruptor or reflector method on either side of Road crossings to signal approaching trains and turn on a flashing RED LED. Remote tracking can also be wire to a trainmap with indicators of trains crossing and direct and speed.Bar-code scanner is deceptively simple until you have to deal with laser beam safety, label speed tracking rates and computing bar gap interval time to compute speed and validating contents of code to determine direct

ion in software.Breakdown the project into;IR can detect interruption of signal on either side easiest or reflection of signal from the same side with a wider range of detection. THe sequence to two adjacent detectors tells which direction and the time interval indicates the speed. This can be measured with either analog or digital methods.IR barcode scanners either rely on the code going past the detector at aconstant speed or the emitter being reflected past the barcode to be detected by scattering of light or absorption of black carbon. Steady laser beams facing up would need to be optically changed to lower the power to a safe level or spread and then focused for a short path length to reduce power density of stray light.

Different LED tubes are different from the light source and materials that determine different price and safety, and the LED tube has a built-in power supply, and the agency different decisions is different.Century Ruiguang Company Engineering Department Li Manager's current technical security issues related to LED tubes, for the type II anti-electric shock type, requires LED tube input contact to reinforce insulation resistance and electrical strength, many built-in power transformers and LED module aluminum substrate Improper installation, causing the test to pass. Or many companies use non-separated power supplies in order to save costs and power efficiency. Internal wiring is mainly linear and insulating thickness, mechanical damage, and insulating layer. The inside is basically can't be in contact with the lamp shell of the aluminum, and the insulation is enhanced. It is also necessary to avoid internal wires and power supply directly to contact the outer casing and prevent the wire from being broken. In terms of structure, it is necessary to prevent insulation of the lamp head, screw, and contact metal surface, and the corresponding lamp head plastic should be used to prevent melting. Since the screws of the LED tube are directly locked, they are required to pay attention to the creepage distance and electrical interval. The internal power supply and the aluminum housing are needed to be separated from the insulating sleeve to reach the power level. The lamp holder and the lamp body are relatively insulated to prevent leakage of the shell.Article Source: LED tube
