content: Can higher temperature ( about 70 degrees) makes damage to LCD Samsung galaxy i9300 ? I exposed LCD to that temperature and now the starting logo turned into GREEN colour ( and LCD has more green colour too instead of default white color). Another LCD works correctly, so it is NOT a problem of the mobile.I think the command ,that the starting logo should be white, is programmed in LCD but is there any program( flash program) that can change that properties?Thanks

Getting up 1/2 hr before going to bed... - Page 1

content: I'm sure many of you in the UK and I'm sure some in Oz and NZ are familiar with the 4 Yorkshiremen.Well Friday I truly have to get up a half hour before going to bed... I'll explain.This past month I had to trade shifts with a coworker so he could get more experience during the day shift when our facility is fully staffed and production is running at a higher rate.So up until this week, that was 4:30PM to 1:00AM.But there's also this thing our facility does during the week of July 4, where you work 4 10 hour days in exchange for an extra day off during Christmas. So that makes my shift this week 4:30PM to 3:00AM since the evening shift works 2 hours later and the day shift works 2 hours earlier.That puts me getting home around 3:30AM. I'll usually have a little something to eat watch some Youtube and I'll be actually forcing myself to go to sleep a little after 5:00AMAlso this week, my wife's Aunt who had been not doing well for a while passed away, and I had been asked by my wife's family to be one of the pallbearers with the burial on Saturday.I thought ok, won't be getting much sleep that night, but I can manage and sleep when I get back.There was also a memorial/visitation service planned Friday evening and my wife asked if I could get off for that but I wasn't quite sure since I was the only one there. Another co-worker overheard me and said she wanted me to be with my wife that night and said she'd trade shifts with me.So now on Friday, I have to be at work at 6:00AM meaning I truly will have to get up at 4:30 which is a half hour before I'd be going to bed.And at this moment I am drinking coffee from a chipped cup, but did not have a cup of hot gravel for breakfast.

content: Hi,i recently download the videos of the EEVBlog so that i can copy them onto my mobile phone or just quick search for a video and seek in the video. I now hat the idea to make a public BitTorrent Sync folder where everybody can access the video files or upload new videos if i am too late with the latest episode. It would be very cool if Dave would join and upload the new episodes himself.So if anywone wants to join me you can get the videos from the RSS feed (http://www.eevblog.com/feed/) what somehow does not work at the moment :-/. I will have to take a look at it later... perhaps direct download it from youtube.I did it via the torrent feed before (http://bitlove.org/eevblog/torrent) which is not supported anymore by Dave.If you don't know BitTorrent Sync you can view this videofrom 49:00 onPlease tell me if you like the idea or not. But don't blame me for my low upload speed. If many people share the folder it will be much quicker. The Secret is R7WUCQDCHJ25XLQCVHEVA4P7BPIQ7OIQT (which is at first a read only secret. Please contact me if you want to help me and get write access)Elektrofreak

But this will reduce the work of every user and be easy to be used by everyone. That's it

Hard to misread these, they just have the one green band on them. 20% tolerance, and they drift so nicely that they can go from 6R to 4r as they heat up, and when they hit 70C the wax impregant melts and makes them glossy.

Due to their high power requirements, OLED phones such as the Galaxy S3 and S4 have low maximum brightness compared with comparable LCD devices.Organic light-emittingtransistors(OLETs) offer a potential solution, and obviously can also incorporate a switching function into the display technology itself.Some links:http://phys.org/news194506432.htmlhttp://spectrum.ieee.org/consumer-electronics/audiovideo/nanotubes-promise-bright-future-for-displays

content: Hello all.To assist with some home renovations I just finished putting together an old Dick Smith Electronics Stud Finder finder kit. However after double checking and triple checking everything over I just can't get the damn thing to operate properly. The issue with the unit is that no matter what I do, whenever I get within a 600mm radius of it, it just starts beeping and blinking its red LED like crazy. As you can imagine, this makes it quite a pain to use for its intended purpose.Has anyone else experienced this problem?

Siglent Equipment... Old or New Design !! - Page 1

content: I have been doing a lot of searching for interest sake, at a Siglent SDG1020 Function Generator; it's specification is much better than the ATTEN ATF20B DDS on E-Bay, and sells under £200; where the Siglent is between £200-250, and gives you much more for your money.Apart from the price, I decided to look up Siglent web-site and found it's series 2000 model, URL:http://www.siglent.com/en/product/detail3.aspx?id=100000001526838&nodecode=119008003Anyone know how recent the SDG1020 could be, or is it now an old model; I ask because E-Bay sellers touted this model as new, however there is a series 5000 e.g. Siglent SDG5082 being much higher in frequency 80 Mhz BW, are these the newer model or just because they are a higher frequency model range... just interested, any ideas ? !

content: Ah, thanks Mike for this information, much appreciated.Don't know how I missed the first posting on Siglent SDG1020 and Dirty Signals... very informative throughout the membership input.I have to admit, was thinking of buying this model while I am designing an analogue function generator, around the MAX038 chip, mainly because I need clean square transitions, along with the sine, triangle. Yes I know, the chip is old but it's all there, colpits osc driven; however what lets it down, is the roll-off around 4 Mhz from the 2 volt PtP output, to around a one volt at 20 Mhz.So currently solving the 20 Mhz end equalising at 2 volt, so found a LM6172IN 100 Mhz BW at unity, it performs best; I have a 100 mV deviation between 3 Mhz to 20 Mhz, it's acceptable for what I need, and now just about to work on a sweep ramp for the chip.It's so tempting to just buy a generator, but these DDS designs seem to have issues beyond the jitter for my use, mainly due working at Htz and HF ends of the spectrum.

content: On many new cars with LED tail lights, I find myself being *really* distracted with their flicker. When I look directly at them, I can just "feel" it's flickering... it has sort of a non-uniform look to it. But what is most distracting is when your eyes move to the side, and you see a string of images of the shape of the tail light across your retina. It causes you to look back at the tail light because "something" caught your eye.I always shoot for as high a refresh rate as I can... if it's just for dimming, I go for at least 1Khz, ideally 10KHz.

If this is the case and the OP is putting aluminum caps into the filter then he will run into issues. In that circuit the signal will be sinusoidal and the aluminum caps will fail as they will be reversed.Neil
