[Nick Poole] does a lot of custom work with vacuum tubes — so much so that he builds his own vacuum tubes of various shapes, sizes, and functions right on his own workbench. While the theory of vacuum tubes is pretty straightforward, at least to those of us who haven’t only been exposed to semiconductors, […]

Many times, when parking our cars in the garage, we accidentally scratch them against the walls or cause damage due to a lack of visibility regarding the remaining distance between the car and the wall. To address this issue, we can create a straightforward electronic project using Arduino and an ultrasonic sensor. This project aims

Grizzled veterans of the computing industry will relate stories of submitting projects on stacks of punched cards, something those of us who stored their 8-bit works on audio cassettes could only imagine. But for those who fancy experimenting with the format it’s still possible to make a basic card reader using LEDs and light sensors, as

Fibonacci numbers are seen in the natural structures of various plants, such as the florets in sunflower heads, areoles on cacti stems, and scales in pine cones. [HackerBox] has developed a Fibonacci Spiral LED Badge to bring this natural phenomenon to your electronics. To position each of the 64 addressable LEDs within the PCB layout, [HackerBox] computed

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′
