content: I must sing the praises of World of books USA, I bought from them a book called Electronic Testing & Fault finding, second edition by GC Loveday , they are all second handbook, books like New, world of books is a charity I think, it cost me £1:49p & £2:00p P&P to the UK from the USA, which is absolutely brilliant , I used these for a while, I'm not fussed about a book been brand spanking NEW all I want is a book to help me get to my final goal, "which is having some idea as to what I'm doing" just thought I'd give them a mention "World of Books"

And, when they get there, they will go through your junk box, shudder. See below link to a story about an printer owner whom the police are accusing of having made a "plastic trigger".http://www.express.co.uk/news/uk/439075/Police-clarify-toy-shop-gun-claim--Below is a link from makerbot about 3D printers the Law and Science Fiction Writer Cory Doctorow, whom I highly recommend.“I’m going to print more printers.

content: It's crazy, and stupid. I'm not in favour of gun legalisation in this country. (But I can see why it will remain in the US: no way you can get rid of all guns now!)You can go down to a hardware shop and build a zip gun from parts. You can use a lathe to produce gun parts. A 3D printer only makes it more accessible to those with less skill, but the majority of plastic printed guns do not work properly when printed on your average Makerbot.

They only had a problem making the ammunition, but in a country awash with USSR sourced ammunition that was not a problem.

content: The whole "If you got our attention you must have done something wrong..." mentality of many police forces and security organizations is getting down right scary. If you happen to hit that spot, it's guilt until proven innocent and they are going to work very hard to make it a guilty verdict. Combine that with poor science knowledge and the general "wars on stuff", and any 3D printer, exposed circuit board or lab equipment can get someone labeled as a terrorist/hacker/crime mogul.

I have mine set to "Google UK", this allows me to view London Telegraph articles after I have used up all my free views, and it demands that I sign up. TOR was made to allow you to get past national ISP blocks. For videos like these I usually copy the URL, paste it into my browser, and the download.

LCD Displays, to fix or not to fix :( - Page 1

timestamp: October 18, 2013, 12:23:43 am
content: I have a few LCD displays with bad CFLs Everything works fine but the stupid cfls changed color on one side. They are a pain in the neck to take appart and the replacement CFLs are not cheap.In particular I have 2 Dell 22" LCD displays that have LG LM229WE1 LCD panels and they lasted about a year. Probably would be worth it to retrofit them with LED strips but then you would need also another power supply. I've repaired lots of displays in the past specially when you can swap parts or recap the power supply or the LCD controller but to reach the fluorescent tubes is a pain in the neck. I'm running out of space to store this displays in my garage I hate to throw stuff away that is not that difficult to fix but is probably not worth to spend the money.

Definitely not worth for me to retrofit them with LEDs as I got them for free and the LED kits would cost more than a new or used working display. I have 4 22" displays that came with terrible ccfls. They are going bad after 18 months. The internals are LG, the displays are Dell.

Other choices are China Post and EMS.As an example, I selected a touch screen weighing in at 190gns and shipping ranged from $19.89 for DHL down to China Post for $5.47. It might depend on whereabouts you are in Australia but it's not likely to be more expensive than to southern Tasmania

content: The reference voltage for the base of an npn transistor is always the emitter. The base needs to be more positive than the emitter (by a margin). The emitter of the right transistor is basically connected to the base of the very same Transistor (via the base-emitter path of the left transistor). There will never be a lower voltage at the base of the right transistor than at its emitter.

content: Many of us prefer to use an image hosting service - you just upload your photo to the hosting service (which is made to be easy), and it will give you a "BBCode" version of the image link that you can then just paste into your post.I have used imgur.com for years and it does it well. There are many other similar services that do pretty much the same thing (flickr, imageshack, etc).Doing it this way reduces the load on the forums servers and also lets you link to the photos from other things (maybe you want to email someone one of the photos - you can just send them the image link instead).

You probably will find power supply caps are bad, or that the LOPT or caps or driver or diodes is dry jointed ( or the splitter for the EHT, careful the EHT in those sets can deliver 1A at 30kV) or the connectors are dry jointed. Another problem is that often the CRT's are burnt, or there is a bubble in the coolant, which shows as a blob on the bottom of the screen. Another favourite is the digital board going intermittent, though that often just gives odd colours.If you part it out can I have one of the optical blocks, nice lenses there to use as a poor man's board magnifier.

The HID inverters in most projectors can indeed supply a pulse of a few tens of kV followed by on the order of a hundred volts at a few amps, but that's nowhere near a few tens of kV and a few amps at the same time.

content: Point-to-point is almost certainly the reason. Look at the transistors in this photo - those leads go all the waytothose turrets, but alsothroughthem, and this is one of the more compact p-p layouts.As for gold - I don't think it has anything to do with noise. The only effect it will have on electrical performance is if the device is socketed - once they're soldered they are solidly connected. I suspect it has more to do with price. Semiconductors were expensive, andgoodsemiconductors were more expensive. The gold plating was less expensive back then and made them last longer without somebody having to take a knife to the leads and scrape off the corrosion before soldering. I'd guess those diodes were expensive types as well. (Edit: Yeah, now I see you said they're Zeners.)

The boards have an accelerometer, gyroscope and e-compass, come from U.S.A., cannot be exported to Portugal (and have a big sticker "Made in China"). Mouser is nice because for orders over a certain amount, shipping is free.Second try: ST Online shop. Order almost complete, but suddenly, there is a small text that says "Order fulfilled by Mouser"...Third try: Ask ST sales, where can I buy one of these boards.After two weeks, received email from ST asking why my order was not complete.Options:My credit card was not acceptedI wanted to add more items to my shopping cart but could notI did not use the right credit cardI got a better deal elsewhereI changed my mindAnd no additional choices.That's quality customer service!Best regards
