How Do I Attach a Led to a Shure 55 Microphone?

Do you want a LED or a lead? do you want to drill holes in your expensive toy and what for? It is easy to tape a LED & battery onto the case or even drill a hole, but why?

1. LED headlight strip legal in NJ?

if they catch it you get ticket/hard to spot when its not colored light

2. How to toggle LED on button press?

success case tested OK,modified from arduino examples.UNO r3,atmega 328 try it !!!!!


Led Zep!

4. Stuff about under-car led lights?

Yes theyre probably illegal to use on public streets. If theyre illegal, you get a fine (and probably have to remove them)

5. Who led the WWE in each eras?

Bruno Samartino, bob backlund, Superstar Billy Grahm Hulk Hogan, Randy Savage, Ultimate Warrior Bret Hart, HBK, Undertaker Steve Austin, The Rock, HHH Brock Lesnar, John Cena, Batista John Cena, Cm Punk, Sheamus Not sure if I am right about all those, because I did not start really watching until the Attitude Era!

6. LED help yo. 3V led with 3V battery?

If you have a 3 volt LED, it means that the junction offset is 3 volts. What happened is that the battery discharged and it's voltage dropped slightly to something below the offset by a few millivolts. LEDs are current driven, so if your LED is a 10 mA device, you need a higher voltage, like 4.5 volts with a resistor in series. The resistor would be 1.5/0.01=150 ohms. If you omit the resistor, you will destroy the LED as the current will try to go to infinity.

7. laptop led-backlit display ?

I do not have one, but i have been looking into it. What I have read about say that the led lights use abour 10% to 15% less power then the regular ones


When i connected the 5v source to the circuit the led started blinking, but afer 5-6 seconds the became very fade. When i connected the circuit to a 7v source the the led did not blink, it bliked for 2 sec. and remained stable and fade. The changes which i have made to the circuit are:- Resistors - 100k instead of 47k, And no resistor at the place of 100 ohms. And i will soon post the images of my circuit. Ihave checked every thing and everything is working

9. pink floyd vs led zeppelin?

Both bands are perfect in their own ways. Asking me to choose between them is like asking a dog to stop licking himself. It just ai not gonna happen man. It is an impossible decision to make. Both bands are 10s in my books

10. Is my nail lamp UV or LED?

UV is about the frequency of the light. It means Ultra Violet, like Beyond Violet. LED means how the light is made. It means Light Emitting Diode. How long your cure your nails depends on the instruction that came with the gel. Your light is a UV light. The light is made by an LED to save electricity.

11. Fixing a flickering led

Hard to say without a bit more info (photo might help) but here's a few thoughts: It's probably got a little WLED driver IC (here is an example) that's stopped regulating properly. This could be due to one of the components involved in it's operation (inductor, diode, capacitor, etc - see datasheet) failing. It could be something to do with the dimming control if it uses it, or even power supply problems/dry solder joint somewhere.Follow the trace from the anode of the LED to the nearest IC and take a look at it and surrounding components. Check all the solder joints look okay. You could try powering it up it, and tapping gently around this area with a plastic implement and seeing if the display lighting "responds", this can give clues as to the problem area. Also heating with hairdryer or cooling with freezer spray can tell you things. Thanks for the pictures, they are helpful. Could you possibly take another one of the area highlighted in the picture below and also post the part number just in case it's not readable (you can gently bend the large inductor L7 leaning over it out of the way):I would try tapping/wiggling the connector (the one with LED /- on it) a bit and around the highlighted IC too. EDIT - here is another better snip of what I think is likely to be the LED driver, although I still can not quite make out the part number (I had a couple of tries on find chips with the characters I can see but no luck):Notice what looks like it may be some corrosion around the IC, the solder joints look like they could be a potential problem. Tapping/pushing gently directly on each individual pin may locate the problem. If the problem does lie with IC6, simply reflowing all the IC pads may fix the issue. If you do this use plenty of flux if you have it, if not at least tin your tip with some fresh solder then wipe the excess off. Do not solder the pins for too long, you should just be able to touch for a second or two and it will do the trick.

The New Technology of OLED 5g TV Will Be a Turning Year for the Color TV Market in 2020
As the only truly mass-produced product in the next generation display technology roadmap, OLED is ushering in a "highlight moment" - although the sales growth in 2019 is limited, the joining of Huawei and Xiaomi is shaping a new image of "OLED".The killer mace of Internet brands?Recently, South Korea reported that LG display will supply OLED panels to Huawei, and the two companies are negotiating the supply. It is reported that this will be an emerging "TV" with 5g function.Lenovo thinks that the 5g package of the three traditional telecom operators has been officially launched in China; The fourth 5g license has Zhao Jingchun, chairman of China Radio and television. At the recently held world 5g conference, it was revealed that China Radio and television will promote 5g business for individuals next year. Huawei's smart screen series products will receive a "completely different product form upgrade" in 2020, which is a high probability event.It is also reported that emerging TV manufacturers Vizio and Xiaomi plan to use OLED panels next year to enter the OLED TV market. It is even reported that Xiaomi has signed a supply agreement with LGD for OLED display panels next year.If the radio and television 5g network is commercial, a batch of 5g TVs must be listed before. This is a "great opportunity" for communication enterprises and Internet enterprises to enter the color TV market. Industry experts believe that not only mobile phone companies that have "news" at present, but also other mainstream mobile phone manufacturers may launch 5g TV next year.In this context, OLED products with continuous tight supply of display panels will be particularly popular: just as OLED used to be synonymous with high-end in the mobile phone market. 5g color TV market, this scene may accelerate. In particular, considering that the new capacity of OLED panel supply of LGD in 2020 is concentrated on the 8.5 generation line in Guangzhou, there is no reason for domestic brands not to "get the month first".Therefore, 5g OLED, as the killer mace of the color TV industry in 2020, especially the mobile communication and Internet brands, has a sufficient "value foundation".Reshape the value chain of color TV, new brand new technologyAt present, the pattern of the domestic color TV industry, in addition to Xiaomi's great success in market share and sales scale by relying on low price and high quality, the traditional disk is still not much different from that 10 years ago."Among more than 10 innovative color TV brands, only Xiaomi is still active in the front line!" this is a true portrayal of Internet color TV entrepreneurs in the past few years. In this regard, industry experts believe that this is mainly because the "new brand" has no "substantive technological breakthrough" except "image, price and more dependence on e-commerce"—— The old routine of price war has also brought financial pressure under huge losses.The biggest feature of 5g OLED combination is the "hardware technology" which is very different from the traditional mainstream LCD TV.Wu Zhanghao, vice president of LG display and Minister of TV business, predicts that the sales of OLED TVs in China will reach 300000 400000 units in 2019, and the sales of OLED TVs in China is expected to reach more than 1 million units in 2020 - this product with short supply and growth is a good helper for the new brand to "create unique" technology competition value.On the other hand, 5g TV technology is bound to create a new concept of "cognition" between traditional TV brands and mobile phone and other communication enterprises. As a global leader in 5g technology, Huawei obviously has outstanding advantages in all aspects, especially in the fields of 5g signal processing antenna, chip, codec and so on. Industry insiders believe that the technical core capabilities of 5g TV and Huawei smart screen will be improved across dimensions."The new round of communication brand TV is very different from the previous Internet concept brand: because this round of new brand entry has 5g, OLED, fan aiot ecology and more hard core content."The battle for high-quality resources begins. Should the color TV industry changeFacing the upcoming 5g OLED color TV war in 2020, what is the biggest variable? The answer is the battle for upstream resources.On the one hand, the supply of OLED TV panels is always insufficient, which greatly limits the improvement of OLED market sales. For example, the data show that in the third quarter of this year, Samsung Electronics sold 1.16 million QLD TVs worldwide, a year-on-year increase of 520000 and a month on month increase of about 70000. Similarly, as a high-end TV, LG OLED TV sold 1.06 million units in the first three quarters, an increase of only 1%.On the other hand, the supply of 5g related chips and other products is also in the "initial stage". Unlike 4G new products and system products, high, middle and low-end gears are fully supplied. In 2019, the layout of many mobile phone brands on 5g mobile phones actually received the restriction that the chip is not in place. For example, apple is a typical example.Therefore, in the expectation of tight supply, Huawei Xiaomi seizes the new technology of OLED 5g TV, which has the effect of "dimensionality reduction and attack on traditional brands". Industry experts believe that 2020 will be an extraordinary "turning year" for the color TV market!
