Today I want to show you guys the Coast TX40 LED flashlight, which is extremely bright at 164 lumens. While not touted as a security flashlight, I'll show you exactly why I think it could be used as one. Additionally, it can also be mounted on your favorite shotgun or rifle.nnAmazon: http://amzn.to/17odsA6nCoast: https://www.coastportland.com/tx40-led-flashlight.htm Less

Demo of a five channel LED / flame-less candle circuit. nnRunning in premium mode. Addition of external LED drivers driving 50mA into 5 LEDs. Long as your led driver draws less than 12mA from the micro you can use all 5 channels at once. Results in a smoother ficker effect. nnThe 5 leds could be split up into individual candles as well with a course effect at each candle. Less

**Subscribe for a future video on how I make these**nJust a collection of clips from a project I've been working on. It includes live light painting techniques I came up with in AE, timelapse clips and the light up dudes. I've made 3 LED stickman suits and a color changing RGB LED suit for snowboarding. The LED strips that I bought don't hold up well in the cold so I need to spend a little more money to get some better ones for future video. This was shot at Mountain High last season (12/13).nnMusic:nhttps://www.youtube.com/watch?v=kvxJTIzPiQU Less

Kisai Console Wood is available exclusively from: http://www.tokyoflash.com/en/watches/kisai/console_wood/nnKisai Console Wood combines vivid LED lights with a natural hardwood case, creating a cool watch design with both classic and futuristic elements.nnKisai Console Wood looks like a sci-fi control panel but reading the time is simple when you know how.nnThe hex shapes indicate hours (1-12), the gauge at the bottom indicates five minute intervals and the level on the left indicates single minutes 1-4.nnAfter wearing the watch for a few hours, you'll be able to read the time at a glance.nnKisai Console Wood has been carefully crafted from 100% natural wood in very limited quantities.nnAvailable in red sandalwood with green LEDs or dark sandalwood with blue or green LEDs, the digital tube interface is set beneath a mineral crystal lens with mirrored detail separating sections of the display.nnThe top surface of the case has been curved and the visible wood-grain highlights the contrast between natural material and modern technology.nnBeing made of a natural material, Kisai Console Wood is light and comfortable to wear and every single watch has a unique color and grain pattern.nnThe links that make up the strap are individually made and the strap can be adjusted like a normal watch to fit your wrist perfectly.nnLike all wood watches from Tokyoflash Japan, a clear coating has been applied to Kisai Console Wood for protection.nnKisai Console Wood is USB rechargeable. Just connect to your computer with the USB cable provided. One full charge will take 3.5 hours and each charge should last 1 month. There are 300 charges in one battery and the battery is replaceable.nnAn animation is programmed into Kisai Console for night time. Every fifteen minutes between 6pm and midnight, the LEDs will move around the display in a suitably sci-fi pattern.nn=============nMusic: Seas of Mars by Jahzzar.nhttp://www.jamendo.com/en/track/1052774/seas-of-mars Less

An electromagnet levitates a ring of LEDs attached to a coil. The LEDs are powered using a wireless power transfer from another coil under the electromagnet. nnLevitation is achieved using a Hall effect sensor and a proportional controller implemented on a KA7500 SMPS controller.

In-depth look at the new HUE LED lightbulb by Philips - one of the first bulbs to change colors and brightness, all controlled by a smart phone app!nnCouple notes I didn't get into the review - nI was concerned about the standby power the bulbs and base station would use, but with all three bulbs AND the base station plugged in and the bulbs off, the power consumption showed 0 watts on my meter, so less than 1 watt.nnAlso, while you can group bulbs in a scene, and name the bulbs like "Livingroom 1", there is no good way use the groups across scenes. It would be better if you could create "rooms" of bulbs, then drag them onto the scenes. Again - all first generation software issues. It will get better. Less

What's an LED TV? Can you save money simply by buying the right TV? LCD TV backlighting is a complex subject, and the marketing of different TVs to make them stand out on at your local electronics store is often designed to confuse you further!
