Fresh hacks every day
About a year ago, [Anthony] decided to embark on his biggest project to date. He wanted something with a ton of LEDs, so when the idea of recreating the classic electronic Lights Out game came to mind, he knew he had the makings of a killer project. The finished Lights Out arcade box is a wonderful piece of work with sixteen 17-segment displays and just as many LED illuminated arcade … [Read more...]
The LVL1 Hackerspace held a hackathon back in June and this is one of the projects that was created in that 24-hour period. It's a 3D scanner made from leftover parts. The image gives you an idea of the math used in the image processing. It shows the angular relations between the laser diode, the subject being scanned, and the webcam doing the scanning. The webcam is of rather low quality and … [Read more...]
The location clock found in the Harry Potter books makes for a really fun hack. Of course there's no magic involved, just a set of hardware to monitor your phone's GPS and a clock face to display it. [Alastair Barber] finished building the clock at the end of last year as a Christmas gift. The display seen above uses an old mantelpiece clock to give it a finished look. He replace the clock … [Read more...]
[Chipsy] found himself with an interesting problem. The room that serves his home theater has a wall mirror which reflects part of the screen during viewing. In an otherwise dark room this was very distracting. His solution was to add a blind that covers the mirror during viewing, but who wants to constantly pull that down and back up again? Since the motorized projection screen he is using has a … [Read more...]
Over at the LVL1 hackerspace in Lousiville, [Brad] is putting together a workshop on etching PCBs at home. [Brad] wanted all the participants to take home something cool, so he settled on an Arduino clone as the workshop's project. The clone [Brad] used is the Nanino, a single-sided board we've seen before. Unfortunately, there aren't any CAD files for the Nanino and doing a toner transfer … [Read more...]
[Osgeld] is showing off what he calls a sanity check. It's the first non-breadboard version of his Pocket Serial Host. He's been working on the project as a way to simplify getting programs onto the Apple II he has on his "retro bench". When plugged in, the computer sees it as a disk drive. The storage is provided by an SD card which is hidden on the underside of that protoboard. This makes it … [Read more...]
[Hasbi Sevinç] is using perishable goods in his electronics project. The orange, tomato, and two apples seen above act as keys for the virtual piano. The concept is the same as the Makey Makey which is often demonstrated as a banana piano. This implementation uses an Arduino to read the sensors and to connect to the computer running the piano program. You can see there's a fair amount of … [Read more...]
