The Pac-Man Bus Stop For Gamers At Heart

DSCF3537Combined

Waiting for the bus can be drag. You never know exactly when it will come, always looking down the road hoping to spot the vehicle as it turns a corner. When it doesn’t show up right away, the result is usually staring down at a ‘smart’ phone checking it for any incoming messages. Directing the attention up might produce a list of estimated arrival times and maybe even a map showing the routes that are taken throughout the day. But there is only one bus stop in the entire world, that we know of, where people can play Pac-Man while they watch for the bus to arrive.

It was created by the combining efforts of two maker communities in town. Norwegian Creations and Trondheim Makers teamed up to build an interactive gaming display that gave individuals the ability to pass the time by directing the famous video gaming character around a blue maze, eating yellow pellets and avoiding colorful ghosts along the way. This display was also made to raise awareness for the upcoming Trondheim Maker Faire that year. They choose Pac-Man as the foundation and integrated a slightly modified invention kit called Makey Makey with a Raspberry Pi running RetroPie into the actual frame of the bus stop. The people involved must have had some serious business connections in order to get approval for that. They figuratively hacked into the bus stop’s power grid gaining the necessary 230 volts required to energize the custom gaming unit. Once hooked up, anyone standing by could play Pac-Man until the bus came. [Ragnar] at Norwegian Creations told us in an email that future ideas of theirs include syncing up several stops that can communicate with each other, which could lead to some great multiplayer interactions. They also have a fantastic video that they uploaded that shows the building process of their current design. Check that out below, and let us know what other types of games you would like to see at a bus stop near you.

LED Light Staffs For The Ultimate Portable Rave

3531621392887203462

[risknc] and [mpinner] have been working on a couple of LED light staff designs for a while now and have come up with a prototype that can light up the night with an array of streaming colors. There is even a dial that can turn up and down the brightness.

Originally, [risknc] began developing his own project at SpaceX and dove further into the idea right before Burning Man. The visual effects, when twirled through the air, produced an extremely bright flow of energy that can be seen circling around the user.

The 8ft long carbon fiber staff was stuffed to the edges with RGB LEDs. Neopixel strips at 60 LED per meter were used to alternate between colors, and a whole bunch of white capable LEDs were embedded into the staff as well. One of early designs was purposefully left at a local hackerspace called Crashspace in Culver City, California. Photos of community members trying it out surfaced on the hackerspace’s website. In addition, a description of the staff and a few high-quality photos of the ‘Sparkle Stick’ were uploaded on to the Suprmasv projects page. Searching through the pictures reveal an instance that shows the LED light staff being used during a flow session with a fire poi spinner in the background. Perhaps there is a way to combine LEDs and fire? Anyways, a later version of the staff was tested out at the 2014 Maker Faire in San Francisco.

Full specs and logs of the project can be found on Hackaday.io. A quick video of [mpinner]’s light staff being spun around comes up after the break. In the video, it looks like they are testing it out outside of Crashspace as they run through the darkness of the alleyway in the back, lighting up the area with a nice LED glow. Plans for the future include building a bunch of them and wirelessly syncing them up. CAD models will be uploaded soon as well.

Extrinsic Motivation: Integrated Room Sunrise Simulator

4544731407291141702

A Hackaday Prize entry that didn’t make the semifinal cut but deserves its own featured post is this wireless alarm clock that simulates a sunrise in the morning. It was created by [Ceady] and connects to an in-wall dimmer that slowly but surely increases the light over 10 minutes to help gently wake a sleeping person up . The Wireless Interface controls the speed of the illumination mechanism and has the ability to turn the lights off when the snooze button is pressed. Is is a neat little hack that brings together a typical alarm system and in-house lighting in a nice internet-of-things type of way. We foresee items like this being used in everyday household bedrooms in the near future.

Circuit schematics have been uploaded to the Hackaday.io page, along with detailed project logs and a list of the component’s parts. A video of the alarm clock being tested out comes up after the break:


SpaceWrencherThis project is an official entry to The Hackaday Prize that sadly didn’t make the quarterfinal selection. It’s still a great project, and worthy of a Hackaday post on its own.

Homemade Nerf Blasters With 3D Printed Parts

esltcollagesuperawesome

This spectacular bullpup nerf gun was developed by the guys over at Mostly Harmless Arms. It is complete with 3D printed parts in a variety of colors. The Extension Spring/Latex Tubing (ESLT) Blasters were based off of [Kane]’s snapoid trigger design with 1/4″ aluminum for the plunger rods which worked out really well. [Prince Edward] adapted [Kane]’s work and modified it with 3D printing in mind. The original post from 2012 gave an in-depth look into where the idea started.

The documentation for all the printed part files and high quality photos can be found on Nerfhaven. It is really nice to see such a clean design that can be fashioned together on a relatively small budget. This makes these playful nerf blasters easy to duplicate, allowing for a full out office war. Granted, access to a 3D printer is needed, but additive manufacturing devices are getting more and more common these days. Now it’s just a matter of seeing how well they work, which can be deduced from the videos after the break:

Gemma-Powered NeoPixel Sound Reactive Drums

adafruit_products_drum-slide-out

This tutorial from Adafruit shows how to create a custom interactive drum set that lights up with sound. It uses a mic amp sensor that is connected to a miniature Arduino Gemma board to detect when the instrument is being hit by the sticks. Neopixels then illuminate into a range of colors creating a beautifully synced up music presentation.

The container that houses the electronics is 3D printed. The entire circuit is integrated into the snare, mid-tom, hi-tom and a drum kick. All the code and step-by-step instructions can be found on Adafruit’s website. Now imagine something like this being packed up in a suitcase and carried from venue to venue as an up-and-coming band travels from state to state on tour; especially at Drum n’ Bass raves or electronic based music festivals. A video of the kit being used is below.

An IPod Dock Converted Into Chromecast Speakers

CoQIKNJ

[easybakejake] figured out a way to fuse together an iPod speaker dock and a wireless Chromecast receiver. His method utilized a modified HDMI-to-VGA adapter. From the looks of it, apps like music for Google Play, Pandora, and Music All Access seem to able to be streamed through this device.

A few problems did come up with this project though when researching the functionality of this music hack. For one, there is little to no documentation since the tip came to us through a Reddit post. Another inconvenience had to do with supporting different monitor sizes. [easybakejake] confirmed in the comments of that post that he ran into an error where the input was not working; probably due to a resolution issue. Eventually, he got it working and dubbed the device the MusicBox. Now stick it on a roomba and get it to DJ a party (like this Parks and Recreation skit that follows after the break):

Laser Engraved Business Cards With LEDs

Plexiglass-LED-Lit-Business-Card-1

Regular paper business cards are boring. They are flimsy and easily forgettable for the most part, and when stacked together or thrown in a pile, it’s hard to locate a specific one; like trying to find a needle in a haystack. Plastic cards aren’t much better either because they still fall into that ‘who cares’ category. But plexiglas business cards with laser cut etchings beautifully lit up by an LED?! Yes please.

The design was developed by Romanian engraving company called Gravez Dotro who fixed the problem of simply glancing at a business card, putting it in a wallet, and causally forgetting about it later, never to contact the person that gave it out. If someone hands away one of these though, the receiver is definitely going to remember it. The solution isn’t that high-tech and just about anyone with access to a laser cutter can make their own. It will be interesting to see what people come up with. If you feel like creating one, be sure to send us pictures. We would love to see them. Video of the design comes up after the break.
