Hack a Day
[Bill] is back with another fantastic video explaining a piece of intriguing hardware. This time, he’s explaining how a CCD works. For many of us, these things are part of our daily life, but aside from the fact that they capture an image, we don’t put much thought into them. [Bill] breaks things down in [...]

Hack a Day
When a few lights in the dashboard of [Garrett]‘s truck burned out, he was looking at a hefty repair bill. The repair shop would have to replace the huge PCB to change a few soldered light bulbs, so he was looking at a $500 repair bill. Lighting up a LED is everyone’s first project, so [...]

Arduino + PS2 controller + R2D2 Here’s an unbelievably real-looking R2D2 replica driven by a PS2 controller with an Arduino inside that plays sounds from the movies. Too bad we couldn’t find any more details about it. [Thanks Bill] Server build time-lapse [Justin] and his colleagues spent five days upgrading their server by building a [...]

Hack a Day
[Bill's] worked on his homebrew computer for almost a decade. He didn’t start with a Z80 processor like a lot of the projects we’ve seen, but instead build the CPU itself from 74-series TTL chips and a ridiculous amount of wire wrapping to connect it all. The video after the break shows off the functionality. [...]

Hack a Day
[Bill] Decided that his living room could use some more light, or at least some more colourful light. To meet his needs [Bill] has designed and build what he describes as a modern/contemporary chandelier. The chandelier uses about 250′ of fibre optic cable to distribute the light from eight LED’s, light from the fibre optics [...]

Hack a Day
[Bill the “Engineer Guy” Hammack] is back with another lesson in the science behind the technology we know and love, but might not fully understand. This time around he discusses fiber optic cabling and how it is used to relay data across distances both small and large. He starts off by showing how laser light [...]

Hack a Day
Using IR repeaters for larger home theater setups is not uncommon, but they usually are quite simple. A series of IR receivers are placed throughout a home, all wired to repeat the signals in a central closet where all of the AV equipment is located. [Bill] constructed a solution that works much like a standard [...]

Hack a Day
We have gotten a number of Arduino tips in the last couple days, and we thought we would combine them for your convenience. The first tip we received was for some hints provided by [Bill] on some digitalWrite() alternatives. Similar to some previous research we covered, this tip also includes some tips on how to make the [...]

Precision CRT manufacture Here’s a great video from Tektronix about building a precision cathode ray tube. The tube manufacture method was developed to use in oscilloscopes and we’d guess it dates back to the early 1960′s. [Thanks Bill] Snake on an LED matrix We would have done a full post o this beautifully built LED matrix but [...]

Hack a Day
[Brad] has continued working on the Super Pixel Bros game. We saw a glimpse of this a few months ago but he’s added a lot since then. The game now has enemies; one type is similar to Bullet Bill, another type drops from the sky and walks toward you, kind of like a Goomba. Game [...]
