content: Quote from: GEuser on July 22, 2014, 11:31:49 amBeing somewhat a cynic, I like the Checkout too. Especially the Guilty Mum segment and the theme music at the end.I have one kid who lives in Japan and the other lives in France. They cannot watch the Checkout, or other quality ABC or SBS documentaries because foreigners are blocked from watching them. I don't know why. At least they could provide ex-pats some method of watching quality Australian news and documentaries. Foreigners cannot watch iView either. My guess is the government's attitude is like that of the BBC: You aren't paying for it with your taxes, so shove off. So why do they provide Radio Australia to the world, and the BBC provides the BBC World Service. There must be other reasons. Proxy servers fool the providers, but it is sort of cheating.
Cheap Maplin Amplifier Hums in Hot Weather - Page 1

content: I have a £70 Maplin Amp head "ProSound N73HH"I was in all likelihood ripped off as Maplin are not known for their quality.Anyway when it's really hot like today the 50hz mains hum is loud and clear but on cool days it seems to work fine with no audible hum. So my question is: what have they cheaped out on that makes it do this? Caps or Resistors? Or something else?

content: Hey all, so for some reason my axis 2401+ died, I think my fault(I made a change over teamviewer and it said "restarting the server" but I think you need to pull the power, I always did but couldn't drive over there on that day or the next couple) and now it will not connect to the network. It does try one in like, 10 times, but it doesn't stickAnyways, I need another solution, I have seen a $5 usb capture card but it's on amazon.com and won't ship to Canada.The next options are PCI capture cards. I have limited space in the server but I do have one or two more slots left, and I doubt I need the SCSI raid card, I noticed one of those compact style SCSI connectors on the back of my server while putting it in.This one seems to be a good, cheap option:http://www.ebay.ca/itm/CCTV-PCI-DVR-capture-CARD-with-4x-BNC-RCA-M-F-connector-/180640755770?pt=US_Surveillance_Digital_Video_Recorders_Cards&hash=item2a0f07303aAnother thing I think may exist but I am not sure, is a small box to hook BNC and LAN into and it basically just turns it into an IP camera.These capture cards do support four cameras though, and you can get decent looking quality BNC cameras for $30 + shipping, and they have IR, they look like the ones that come in several hundred dollar kits so I think a capture card is best in the long run, and cheaper than an actual dvr style box, this allows me to get cameras as I need/want them.Just wondering if anyone has any recommendations. I'm going to be using this capture card with yawcam for motion detection, I imagine they can output some sort of video feed like a webcam would, I'm not sure, but being able to do that is important.Waiting to see if someone I know has something like this laying around I could get really cheap, but I doubt it.Also, does anyone know a way to convert TV lines to a rough pc resolution? I'd like to know what sort of resolution images I can get out of these things.

content: http://www.elinetechnology.com/definition/712502-tvl-tv-linesThe analog/BNC cameras top out at 700 TVL I believe, and anything higher would be some digital format (SDI).IP cameras are commonly higher resolutions (720p+). The nice thing about them is you can run power with POE, so just one RJ45 line is required. But may be beyond your budget.

Ring files containing electronic components, where to get them? - Page 1

content: I have seen ring files containing transparent plastic pages with small compartments in them. These spaces hold electronic components (Resistors, Ceramic Capacitors, Electrolytic Capacitors). Each page consists of a lot of components in these separate compartments on these pages. The compartments are closed with plastic lids.It seems that this is the most compact and mobile way of storing all the resistors and capacitors instead of buying a storage cabinet with small drawers and the components separately. The only problem is that I can't find them on the internet. Does anybody know where I can find these component files? I am sure just 1 file will contain all values for a given series.

Recently, I got an email that stated "It is top trace in your file while it is selected 2 layers in the order list. Could you please confirm it ?"In times past, this meant that the operator did not see any bottom traces and assumed I left out the layer information. I assured the operator not to worry and that there are only bottom copper pads not traces.But that wasn't the case.I received PCBs with soldermask and NO COPPER on the bottom layer. It seems I exported the whole directory and missed the bottom layer file. I even checked it in the Gerber viewer, but because I wasn't watching closely, I identified the soldermask as the copper layer.

Tip for cooling a small compressor if you need it. - Page 1

content: Hey all, I have this mastercraft 1/3hp compressor, which can run for about 15 minutes before the case and motor get too hot for me to run without worrying about burning it out. Filling up a 33 gallon tank (the well rite one I got a while ago) took an hour because you could pup for 15 minutes, have to wait for it to cool, and pump for the last 15 minutes.I originally was going to find a way to clank on some sort of manifold and use an old radiator to cool it, but I had a couple old blower fans, so I took some strong hot glue and hooked them up, and it works amazing, after running almost half an hour straight it's pretty much lukewarm on the case, I'm not sure what it's like on the motor, but I also plan on mounting some heatsinks to help cool that off more than just blowing air through the motor itself.It's just powered by an old PC power supply, but I want to add in a transformer and switch so that it's built it, but for now it works amazingly.(It also is amazingly refreshing on your head on a hot day, it blows lots of air through your hair and feels awesome)
Just noticed an odd quirk with Osram LEDs - Page 1
Forum section: electronics / general

author: SirNick
author_rank: Frequent Contributor
timestamp: July 08, 2014, 11:02:50 pm
content: I built an SMD LED demo board (to easily audition my stock parts) and of course managed to swap the power leads on its first power-up. Now, there are some bi-color LEDs on there, but none of them are in an anti-parallel configuration. They just use 4 pads, with all diodes forward biased.So, with reversed leads (and a safe, low voltage input), whatshouldhave happened is -- nothing. At first glance, I wondered why only three LEDs were lit. Then, I noticed the three that were lit, were lit red. Which is weird, since they'rewhiteLEDs. (Osram LW / LCW) Of course, once I sorted the polarity, the whole board lit up in a painfully bright display of every possible color all at once. (Each LED is individually controllable via a breakout header, but they were paralleled for the initial test.)How do you explain that? Dummy light? It seems unlikely they would go to the expense of providing a reverse-polarity indicator for giggles. Maybe they're intended to be used in LED flashlight applications, and the red "night light" is an undisclosed feature? (Or maybe I just haven't scoured the datasheet adequately.)

I remember this coming up on some automotive forums years ago now. I can't find any info on it now but there was some available at that time. Actually not undisclosed, just not well described. Many of their datasheets say reverse voltage will result in red or no emission.

content: Huh. I never knew LEDs came with reverse polarity protection diodes. All the ones I've used up until now just don't conduct in reverse. Unless the avalanche rating is exceeded.The latter was arelativelyrecent discovery as well. I blew out an LED on a breadboard with -5v. Had no idea that could happen. It was only still connected because I changed the circuit around it, and didn't think it would care whatsoever. I was quite wrong. Even more the surprise since it had a rather hefty rating of 50mA.I guess it goes to show, even simple components aren't always as simple as you think. So anyway, thanks for that little tidbit.

Happens to be cheaper than an ESD rated table top, the color can be representative (i.e. green for lead-free, blue for non lead-free), and it prevents most types of damage to the table/bench top (molten solder, impact, ...). Extremely useful stuff IMHO.

What it tells my I can't do is operate the pump when plugged into AC or damage may result.. I can't really figure out why they've done this but am looking for a workaround.The car adapter outputs 12v and is rated to 6.6 amps, the wall adapter outputs 12v and is rated to 400mA. Am I able to trick the pump into not damaging itself when operated from AC by just using a 12v adapter rated to 6.6 amps?

I'd love to get three analog scopes, and hook them to each channel of my speakers, it would be a nice visualizerIf/when I send some random stuff to dave for mailbag I think I'm going to include these, maybe they will be a good addition to his high spec equipmentIt would be funny to see what he thinks of their performance.
