SMARTPHONE managed LABYRINTH
This entire job might have been done as an app, drawing the labyrinth as well as sphere virtually on the screen. however that wouldn’t have been almost as fun as what [Matt] accomplished. He developed a bit Labyrinth which responds to the accelerometer in his phone. Take a close look at that handset. It’s not …
CONDENSER MICROPHONE building
browsing around today, this job caught our eye. mainly because of the visual similarity to, well, personal massagers. As it turns out, it’s a house made studio condenser microphone. We would generally prefer to link directly to his personal page, that has a somewhat more in dept compose up, however it has popups as well …
MASSIVE ETCH A SKETCH FROM TV screen
[Jeri] put together an absolutely enormous Etch A Sketch for The FatMan and Circuit girl show. She had removed the DLP chip from an HD rear projection TV and chose to repurpose the 52inch screen. The movement mechanism uses pulleys from screen doors with nylon lines. The two sets of lines are fed in a …
FPGA EMULATES NES CART; PROTOTYPE SO CYBERPUNK
By now, most of us have had some experience getting ROMs from traditional video games to run on new hardware. Whether that’s just on a personal computer with the keyboard as a controller, or if it’s a more fine-tuned RetrioPie in a custom-built cabinet, it has ended up being fairly mainstream. What isn’t mainstream, however, is …
RASPBERRY PI used TO build A smart television
In the title of his post [Donald Derek] calls this a Google TV you can build yourself. That’s certainly an over-reach. but the project is still a very excellent smart television developed using a Raspberry Pi. The open source project starts with the Rasbian OS, an RPi version of Debian Linux. functionality is developed up by installing …
HACKADAY LINKS: APRIL 9, 2017
[Federico Musto], one of the Arduinos in the Arduino vs. Arduino saga (which lastly concerned an end last September) may have fabricated his academic record. This news comes from Wired, offering files from the registrars at MIT as well as NYU specifying [Musto] never went to these institutions. because this story came out, [Musto] has edited …
FORKNIFE, ANDROID G1 managed ROBOT
When we first saw [Jeffrey Nelson]’s G1 based robot we immediately wondered what the transfer for the controls was. The G1‘s hardware supports USB On-The-Go, but it’s not implemented in Android yet. It turns out he’s actually sending commands by using DTMF tones through the headphone adapter. The audio jack is linked to a DTMF …
RASPBERRY PI REPLACES A VOLVO NAV SYSTEM
[Reinis] has a Volvo S80. one of the dashboard features it includes is a 6.5″ LCD screen which periscopes as much as utilize as a navigation system. The issue is that Volvo stopped making maps for it around five years back as well as there are no maps whatsoever for Latvia where he lives. So …
IR BASED AUGMENTED reality
For a final design project, [Frank] and his group took on an augmented reality project. The goal was to make objects interactively controllable by pointing a smartphone at them. Their solution was Augmented reality universal Controller and Identifier (ARUCI). The system locates controllable objects by sensing IR beacons that contain identifiers for each object. The IR is received …
MINIMALISTIC 555 adding machine
how many 555 timers does it take to add up two 10 digit numbers? [Alan’s] 555 adding machine does it with 102 of them, he designed the machine as an extreme entry to the 555 contest and the original plan was to make it even more complicated. This machine uses the 555’s to implement a …
