Does Anyone Know Wifi LED Light?

Having just read through the information on their website again, it sounds as though these lighting devices consist of a Powerline adapter, which feeds the Internet signal supplied over the power wiring from the encoding module through to an internal router in the lamp that then drives an internal wireless access point. The router function is necessary to be able to support more than one WiFi device at once. Configuration of the wireless network takes place probably over the devices own wireless network and also, I suspect, through the Powerline network unless there is a reset button on the side of the bulb or table lamp. I do not believe there is any Bluetooth interface to the device; however, I suspect it can be configured equally well from any device with a web browser such as Windows or Android. It is difficult to access just what is happening with the lack of detailed information on the website. As you will see from the information I have lifted from their website below, you need to plug in their encoder device to a power outlet and connect it to a router (not necessarily a wireless router) or possibly directly to a modem although that is not explicitly mentioned. Whatever device the encoder is connected to has to provide your connection to the Internet. The encoder then sends the connection through the power wiring in your house to the bulb or table lamp, which provides the WiFi signal that is available for devices within range of that lamp. You will still need an ISP connection and a modem or router to connect the encoder to. The only cables from the encoder to the lamp will be the house's power wiring. I can see on major problem if you want to network to any Ethernet connected devices. Unless there is an option to disable the router function in the lamp, anything connected to the lamp's WiFi will be on a different subnet from anything connected by Ethernet to the ISP's router. This may seriously impede any networking between WiFi and Ethernet devices, These lamps may be an ideal solution for getting Internet access in remote corners of your house, but for a general building wide network they may prove to be totally unsuitable. That's my opinion. They are an interesting device, but I suspect their applications may be limited.

How Long Did the Monolith Remain on Earth?

This is really two different questions...Second question first: I'm pretty sure that it is expressed in later that all monoliths are one and the same, just different representations in our space. Although, that then doesn't fit with the lag of 950 years for communication.First question: the monolith on Europa in 2061 is evidently a long-lasting feature, providing some kind of shelter for the Europan lifeforms, and also, apparently, guiding them (possibly, ever since the events of 2010). I figured this would be the same for the monolith in 2001 - seems I was wrong.Thumbing through the book I find the passage:As he led the tribe down to the river in the dim light of dawn, Moon-Watcher paused uncertainly at a familiar spot. Something, he knew, was missing, but what it was he could not remember. He wasted no more mental effort on the problem, for this morning he had more important matters on his mind.Like thunder and lightning and clouds and eclipses the great block of crystal had departed as mysteriously as it had come. Having vanished into the non-existant past, it never troubled Moon-Watcher's thoughts again.

A little bit later in the book, there is a reference many such 'crystals' and they seem to appear and disappear at the same time. This would indicate that the monolith(s) disappeared after only hanging around for a few nights.However, 3001: Final Odyssey describes the discovery of a monolith in Olduvai Gorge (the site of the famous discovery of Lucy by the Leakeys) somewhere around the 26th century. It became labelled TMA-ZERO (since the lunar monolith was labelled Tycho Magnetic Anomaly One). There's even this passage:For here was an archaeologist's treasure-trove - crudely fashioned flint tools, countless bones - some animal, some human - and almost all arranged in careful patterns. For centuries - no, millennia - these pitiful gifts had been brought here, by creatures with only the first glimmer of intelligence, as tribute to a marvel beyond their understanding.

So - depending on if we are restricting ourselves to the first book/film only - the monolith was only around for a few nights, and affected only one small tribe of proto-homonids (although, other monoliths were also doing this elsewhere at the same time). If we accept ret-cons, then it will still be around after hundreds of thousands of years, although possibly inactive once buried after an unspecified period of activity

Lighting a Room with LED Light Strips

1 Yes, it's possible to light a room with LED light strips. Lots of people do it. But it requires doing your homework. If you are impatient and fly past your skills, the project will probably fail. There are a variety of ways to do it. 2 You'll need a significant amount of 12V or 24V power (24V means half the current, which greatly improves the situation with voltage drop and fading). You will probably want dimmers and amplifiers. And appropriate wiring. 3 Given that this will be your primary light, you should place importance on CRI aka Color Rendering Index. If you remember green fluorescent and some CFLs and very early LEDs, that thing that made them look awful was bad CRI. Hold out for 80 CRI preferably 90 CRI. You should also be thinking about color temperature. 4000K is similar to fluorescents in an office. Old incandescents are 2700K. 5000K is similar to daylight and 6500K is a cloudy day. You don't want colors that are too blue in a bedroom in the evening, because they will make it hard to sleep. If you just buy random LED strips and don't pay attention, you will probably get 5100K, which will be pretty blue. LEDs naturally make blue light and use phosphors to convert it to other colors, so they like to sell you the more blue LEDs because they require less phosphor and are therefore cheaper. RGB or RGBW lights let you dial in any color temperature you want, including some insane ones, but the CRI is fairly poor. I'm not sure I'd want to use RGB as primary lighting. 4 The product bundle you linked is a complicated bundle of products, including an LED strip, a smart WiFi based controller (RGBW dimmer), and a power supply. You probably don't want to use that. If you want control via WiFi or Alexa, then look for a-la-carte controllers or dimmers that do that. Keep in mind that the electrical and building codes require that you have a light in the room that responds to a physical switch in the usual location. That can be a smart switch talking to a WiFi or Alexa type system, but it has to work when you push it. All the wiring needs to be done consistent with NEC low-voltage rules. If your power is over 55 watts (which is actually a lot in LED), pay close attention to those rules

How to add red led light to my white led lights

Whats the best way to wire the red led to this system?White LEDs have a forward voltage of about 3V and red LEDs are about 2V. With a 9V supply you can wire two white and one red in series. To get the right luminous intensity balanced between the white and red you use the LED's rated intensity to increase or decrease the brightness. Doing it this way will not have any effect on battery life if the resistor is changed to provide the same current. When powering LEDs with batteries it is advantageous to use high output (mcd) LEDs. The white Cree 5mm Round LED C503D-WAN has a typical luminous intensity of 48,000 mcd (64,600 mcd max) at 20 mA and a Vf of 3.2V. At 10 mA the Vf drops to 3V and the luminous intensity is still very bright. You could reduce the current to 1 mA and it will still be brighter (2,400 mcd) than many of the cheap white LEDs. Even though they cost 24 they will easily save that much in battery cost. Now that the LED's Vf is below 3V you may be able to wire three white in series if the Vf is below 2.8V at 1 mA. Another thing is to try and match the LEDs Vf with the battery voltage. If the Vf is just a little below the battery's voltage you will get the best efficiency. You must look at the discharge curve of the battery to see how much the battery voltage changes over its lifespan. If you use a 9V lithium battery (or 3 CR2450 620 mAh, CR2430 320 mAh , or CR2032 235 mAh) the discharge curve is such that the battery voltage remains above 8.5V for most of its lifespan. Lithium (good for LEDs) has a very flat discharge slope and alkaline (not so good for LEDs) slope is relatively steep.

source 9V Ultimate LithiumWhereas the voltage of a 9V alkaline will drop significantly over its lifespan. The best way to power LEDs with a battery is to use a boost step up constant current LED driver. There are some very simple boost circuits that work with battery voltages very well such as the MCP1662 in a 5-Lead SOT-23 package. The MCP1662 is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with constant current from a two- or three-cell alkaline or lithium Energizer, or NiMH/NiCd, or one-cell Li-Ion or Li-Po batteries.
