Lumileds has added news LEDs to its Luxeon IR Domed Line with a significant increase in both DC and pulse drive current–up to 1.5A and 5.0A, respectively. The new emitters deliver radiant power of 1350mW at 850nm wavelength (slightly visible) or 1450mW at 940nm (invisible or covert IR). These new IR LEDs are engineered to …

I have toyed with the idea of building a clock for sometime and my sister had a big birthday coming up so I decided that this was a great opportunity to build a clock for her as a gift. My sister has a PhD in science and works as a science educator so I decided …
Three physicists have been awarded the Nobel Prize for revolutionizing the way the world is lighted. The 2014 physics award went to Isamu Akasaki and Hiroshi Amano of Japan and Shuji Nakamura of the University of California, Santa Barbara, for “the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light …

Now forgive my memory, as this was a few years back now. What started out as a children’s spaceship themed bed, turned into an epic build. Supplies The project started with the purchase of a single mattress. I then walked around the local DIY store and started to find shapes that I thought I could …

There are so many authentic looking lightsaber build guides but not many on building a super long lightsaber. Regarding Star Wars, I’m not sure why lightsabers are normal sword size anyway. Its not like the longer the lightsaber, the harder it would be to swing. I assume they are essentially weightless. Just make it 10′ …

With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to …

In the previous instructable I showed you how to get started with IoT using the nodeMCU, in this instructable I will be featuring the Particle Photon which is an easy to use IoT device to get started with designing IoT projects. The particle photon is smaller than the nodeMCU and features STM32 ARM Cortex M3 microcontroller on …

A while back, we constructed a pair of LED skateboard truck-risers. That project was intentionally created without the aid of advanced tools and techniques. We decided to try the concept again but without limiting ourselves. This time around we used custom designed PCBs and 3D printed parts. There was no limiting ourselves to hand tools and …
