Dynalite Dali Problem - Page 1

content: I am working in an installation in which I have a Philips Dynalite DDBC120 controller to which I have connected 63 ballasts with Led luminaires. My problem is that when I order them to light up, they do it asynchronously, some first and others later, not all at the same time. The same thing happens when I order them to turn off. I am programming the system with the Envision Project software from the same manufacturer. Does anyone know what may be due?Enviado desde mi iPhone utilizando Tapatalk

content: If you are controlling the lamps individually it will be painfully slow, DALI is crap like that, but IIRC there is a way to create groups of lamps and then address the group with a common command?I cannot now remember the details, but it will be in the protocol document somewhere.Regards, Dan.

content: I'm just starting out with planning a DALI installation at home so I'm certainly no expert but yeah, you're going to have to assign your individual ballasts to group(s) (there can be up to 16 groups) and then command that/those group(s). If you just want to control all of them, look at using broadcast.Unfortunately the protocol documentation isn't freely available, just bits and pieces but the documentation for your specific controller should tell you how to create groups and assign ballasts/illuminaires.

(Fake) RKC Rex-C100 - Can I change the sensor type? - Page 1

content: I got a cheap RKC Rex-C100 from Taobao a while ago. It's obviously fake and will lack some function of the original.Anyway, I am using a K-type Thermocouple and that is off by about 4°C. My usage range will be 30-55°C, and that is already wide.A few question:Can the sensor type changed? Mine seems for K type, can it change to PT100?Can the K type range be set? The standard is 0-200°C (K01), but I see also a 0-100°C setting (K13). Or is that hard wired to the C100?Can the tolerance be adjusted?I might just re-adjust to the wrong °C, but this silly timewasting drive for perfection....
How to seek out a mentor? - Page 1

content: I’ve come to the realisation that I want/need a mentor who’s an engineer (preferably in electronics/RF related) but I don’t know how to go about finding one, or how you begin a mentorship, whether I pay them, and such. There’s a lot I want to learn and know, but unfortunately I can’t get that mentorship from anyone at my work...do you think it’s necessary to have a mentor? Or just use the extensive resources that the internet offers to act as a substitute?I only know of one other engineer whom I’d approach for a mentor, but he lives in Melbourne (he’s a subcontractor for my company) whilst I’m in Brisbane (Australia btw) so that wouldn’t work out...unless I ask if he’d employ me or something.Anyone else ever had a good mentor? How do you go about establishing the nature of the mentorship?

content: Hi,First off, this is my opinion and the kind of mentoring that has helped me personally and it may not suit you.You should not be paying for mentoring, it is a two way relationship that benefits both, if it doesn't it is not working. But also note that mentoring shouldn't be something that imposes too much on the mentor's or your time - short regular sessions that allow you to focus on important stuff. You can't bring everything to a mentor and ask for help. Choose important things and bring your thinking along. My mentors acted more as guides than solutions (If that makes sense).There is certainly technical level mentoring (which is what I think you are after from your post), but this is often informal and occurs during the normal process of working in a team (well.. it should..) If there is no one you can rely on where you are for this, it is difficult. Perhaps an external mentor can assist, but it takes significant time to convey a nuanced understanding of the project and issues so it would be hard for them to provide solid advice. Perhaps they can provide lessons from experience you can draw on and apply to your situation..There is also more professional coaching type of mentoring. I found that this was best with someone who was external to your work as they will not be involved with internal politics, or have preconceived notions about situations or worse, their own agenda. In this you look at the longer term, your career, dealing with conflicts at work, other non-technical stuff.Really, if you are just starting your career, I'm impressed your are thinking about this stuff. Very encouraging.Ash.

Doppler shift and relativity - Page 1

timestamp: April 03, 2018, 02:54:09 am
content: Say a distant radio station transmits on 100MHz so that is where you would tune to on the dial. Then that transmitter starts approaching you at 1% of the speed of light. The frequency you need to tune to would then be 101MHz but the radio signals would still be approaching you at the same *unchanged* speed of light despite the source now moving toward you.The question is: is this increased received frequency from your POV the same as you perceiving that time at the approaching radio station is going 1% faster than time for you? Does the clock on the approaching radio studio wall look to you as if it is actually going faster than your clock the same amount as the radio frequency is now increased by Doppler shift, or would it look slower?

timestamp: April 03, 2018, 03:08:46 am
content: I do not think there is a necessary relationship between relativity and the Doppler effect. For example, if an audio source emitting sound at 100 Hz moves towards you at 1% of the speed of sound you will hear a frequency of 101 Hz. This outcome does not have anything to do with the perception of time.Therefore I think you are creating a false connection where none exists, or wrongly attributing the cause of the Doppler shift to time dilation.

content: My very poor understanding is that what you are describing is more the "classical" view of things, which just takes into account that light has a defined speed. If your clocks were in sync (from the point of view of an observer half way between them) as described they would stay in sync.However, in reality & relativity the clock that undergoes acceleration slows down, so the accelerated clock would fall behind the stationary one.If your clock was one light-minute away from the other clock, but synced. If it was then accelerated instantaneously to the speed of light, spent a minute getting to the stationery clock, and then instantly decelerated, it would be one minute behind the stationery clock.IIRC the effect is something to do with the square of the speed, so moving at 1/100th the speed of light slows time by 1/10000th.Another way I've had it explained to me, the combined vector of moving in time and space is constant for everything. The faster you move in space, the slower time moves.I never could see how this ensured that everybody could have a consistent view of events, but I am not physicist.As it comes to Doppler effect, you will not see 101MHz, but 100.995MHz , as the transmitter looks as if it had slowed to 99.995 MHz.EDIT: Yes! I did recall almost correctly -http://www.fourmilab.ch/cship/timedial.html

We'd position two PM rotors on a steel topped work bench, they LOOK identical, but one has been de-mag'd (magnets heated to beyond their Curie Temp). An engineer tells the New Guy and an existing tech to go "grab those rotors" and existing tech leads, easily picks up rotor which isn't magnetic, then the fun starts whilst the New Guy tries to pick up the (extremely) magnetic one......

content: I had something very similar.The symptoms of pixellation were more prominent on certain channels, but after some time of observation and some tests, I worked it out.With the TV tuned to a susceptible channel and with my computer off - or with both screens in sleep mode - the TV was perfect. Wake up my computer screens and the problem hit hard. Turn off one screen and the pixellation diminished significantly. Turn off the second and the problem disappeared.My problem turned out to be poor TV signal path integrity that was fixed by replacing a section of coax with a decent quad shield RG6, replacing an unnecessary connector with a soldered splice (watch your geometry if you do this) and generally running the antenna cable away from proximity to my screens.Has been perfect ever since (unless we get soaking rain and a bit of wind - but that's pointing to a trip up an antenna pole).Quote from: sony mavica on March 28, 2018, 03:19:29 amThat's not necessarily aconclusivetest - but it is a positive indication.My bet is you have a problem with your antenna cabling - quite possibly poor connector contact, if not the cable itself. These days a decent quad shield cable is all you should be looking at using.

Blatant lack of calibration on Aoyue 936A - Page 1
Forum section: electronics / general

timestamp: February 28, 2013, 03:48:16 pm
content: Hello all,The guys from the technical lab recently acquired a 852A++ Rework Station and a 936A Soldering Station.Upon arrival, they found that the performance of the soldering station was abysmal: the tip was oxidizing instantly and the solder was a rather sad blob of poor looking material. While competent in melting the solder, there was no wetting, no shine, no pleasure to work with.Well, we've put that on the poor quality of the delivered tip and we've tried a new original Hakko, with exactly the same behavior.After some fiddling, we've found that by setting the temperature to minimum (200C), things were vastly improved, very similar to what you could expect at a normal soldering temperature. Hah! I've constructed a small probe with some thermocouple wire on the tip and guess what?...There was a bloody +150C of difference between the set value and the actual temperature.At the 200C setting, the tip temperature was a rather nice 350C. It was actually easy to fix since the calibration pot is accessible on the front panel by removing a rubber cap. Now everything is OK and the station is actually useful.(One explanation could be that the factory tried to calibrate the station to 392F but they used a Celsius thermometer.More likely, no calibration was ever made)Well, just be aware of this. If you don't have a solder tip thermometer, It's rather easy to use a couple of turns of thermocouple wire on the tip.BTW, the rework station shown a difference of +30-40C between the set temperature and the measure at 1cm at the nozzle.The Weller soldering stations were exemplary: only 2-3 degrees difference.Best regards,Dan

content: I have the same model and mine was the other way - it wouldn't melt 63-37 leaded solder unless you turned it to 400. I'd assume that two completely uncalibrated units would at least behave similarly, since the trimpots are usually sold centered - wouldn't surprise me if the factory oompa-loompas just give it a random twiddle with a screwdriver to make it look like they're adjusting it...

I worked in video production and deadcat's only really have one function and that is to act as a wind shield without affecting the acoustic pick-up of the microphone (i.e.: you don't get that "muffled" sound).The are normally used outdoors or where fans/air blowers are present.If you're filming indoors, even in an air conditioned environment, wind screens are hardly ever required.Pop filters however are very useful in voice-over recording.But yes, it's true, a good cat is a dead cat.

content: Hi guys. If you were to choose a career path in the US, would you rather go for network engineering or biomedical electronics?I decided I wanted to give the US a try and apply for a job there, in 2 to 3 years time. I am interested in the Chicago and Houston areas, but anyone can comment about their own city.I am a mobile network engineer with 2 years of experience.I was/am looking into a masters in cibersecurity. I am currently training to pass the CCNA routing and switching exam.I was recently given the option of getting a biomedical electronics technician job in my country. This job would train me in several countries so that I can work on the equipment of a couple of leading brands of biomedical machinery (MRI machines, X-ray, etc.). Because this training is overseas, I cannot pursue a masters of I do this. However, this training is international, so I guess it’s valid for any company that works on this type of equipment. It looks like this company will pay me more and I kind of need that money to emigrate and settle in a foreign country.I was wondering which one of the two sectors would welcome me better and which one has more space for me to grow into, considering that I don’t have US-specific certifications. (I don’t think that’s a problem in networking but it could be in biomedical).I like both options, it’s a matter of which one will give me more money, stability and room to grow.dI have time to advance my career, I’m in my early 20’s.Which field you think can get me faster/more probably from technician to senior engineer? Which one gives me more places to work for?All opinions are welcome.-Ivan
