    Neo Geo Arcade Gets Second Life with a Raspberry Pi

    neo-picade

    An old Neo Geo Arcade, a Raspberry Pi, and some time were all [Matthew] needed to build this Pi Powered Arcade Emulator Cabinet.

    Neo Geo was originally marketed by SNK as a very expensive home video console system. Much like the Nintendo Play Choice 10, SNK also marketed an arcade system, the MVS. The Neo Geo MVS allowed arcade operators to run up to six titles in a single cabinet. The MVS also allowed players to save games on memory cards.

    [Matthew's] cabinet had seen better days. Most of the electronics were gone, the CRT monitor was dead, and the power supply was blown. Aside from a bit of wear, the cabinet frame was solid and the controls were in good shape. He decided it would be a good candidate for an emulator conversion.

    We’ve seen some pretty awesome arcade conversions in the past, such as this Halloween rendition of Splatterhouse. For his conversion, [Matthew] stuck to the electronics, leaving most of the old arcade patina intact. The CRT did fire up after some components were replaced. [Matthew] ran into some refresh rate issues with the Raspberry Pi, so he opted to swap it out with a modern LCD monitor. Controls were wired up with the help of an I-PAC board.

    [Matthew] had to write a driver to handle the I-PAC, but he says it was a good learning experience. Aside from the LCD screen, the result looks like it could be found in the back of an old bowling alley, or a smokey bar next to Golden Tee. Nice work, [Matthew]!

    Air-Tensioned Bandsaw Simplifies Woodworking Life

    bandsaw

    If you’ve ever had the pleasure of owning a band-saw you’ll know exactly how much fun it is to try to replace the blade, or properly tension it even. [Richard T] got tired of it and decided to upgrade his band saw with a bit of pneumatic power.

    To remove the band saw blade or tension it you have to turn an adjustment knob on the top of the band saw — it’s kind of awkward and really annoying. [Richard] has taken the lead screw out and replaced it with a pneumatic cylinder. He’s added a little control panel with a main valve, and pressure regulator. To remove the band saw blade, he bleeds the system with the valve, and to tension it, he turns up the regulator! It’s simple and super effective.

    This is especially convenient for tensioning because you can watch the blade during the “Flutter Test” while gently turning up the regulator.

    If you look in the right places you could probably build a system like this for less than $50. For a complete explanation stick around to hear it from [Richard] himself!

    Electron Beam Control In A Scanning Electron Microscope

    Electron

    A few years ago [Ben Krasnow] built a scanning electron microscope from a few parts he had sitting around. He’s done a few overviews of how he built his SEM, but now he’s put up a great video on how to control electrons, focus them into a point, and scan a sample.

    The basic idea behind a scanning electron microscope is to shoot electrons down a tube, focus them into a point, and scan a conductive sample and detect the secondary electrons shot off the sample and display them on an oscilloscope. [Ben] is generating electrons with a small tungsten filament at the top of his electron ‘stack’. Being like charged, these electrons naturally fan out, so a good bit of electron optics are required to get a small point.

    Focusing is done through a series of pinholes and electrostatic deflectors, much like you’d see in an old oscilloscope CRT. In the video, you can see [Ben] shooting electrons and displaying a Christmas tree graphic  onto a piece of phosphor-coated glass. He has a pretty big scanning area in his SEM, more than enough to look at a few chips, wafers, and whatever other crazy stuff is coming out of [Ben]‘s lab.

    Video below, along with the three-year-old overview of the entire microscope.

    Hackaday Links: April 13, 2014

    hackaday-links-chain

    Check out this Pokemon Yellow cartridge for Super Nintendo. Wait, what? That is a Game Boy game! Well there is a Super Gameboy cartridge that lets you play them on SNES. This mashes the guts of the two into a custom-decorated SNES cart. Now if you’re more interested in the guts of that Super Game Boy cartridge you’ll want to check out this classic hack which dumped the ROM from it. [Thanks Nick]

    Here are a couple of interesting things from our friends over at Adafruit. First off, they have a high-res gallery of the Raspberry Pi compute module and carrier boards which we heard about earlier in the week. Also, the latest Collin’s Lab has a great video on soldering. We especially appreciated the discussion of soldering iron tips and their effect on heat transfer.

    [Marius] got tired of the static shock from the office coat rack. You know, like the scene straight out of Office Space? But he didn’t disassemble the infrastructure to solve the issue. Instead he connected it directly to ground. Just make sure you stick the wire in the correct hole!

    It’s as if Hackaday is on a quest for the most perfect DIY cyclonic separator. Here’s the latest offering which you can cut out from sheet stock by hand. It’s the alternative for those of us without access to a 3D printer.

    If you think it’s too difficult to build what we refer to as a Daft Punk table you need to check out what [Dan] pulled off. He proves that your LED matrix coffee table project doesn’t have to take up a ton of time or cost an exorbitant amount of cash.

    We should have mentioned this to you before the weekend so you’d have something to watch: you can now download BBS: The Documentary from the Internet Archive. We’ve watched the entire thing and it’s fantastic. If you know what a dial-up modem handshake sounds like, you’re going to be awash in nostalgia. If you don’t know the delight of those sounds you need to watch this and see how things used to be back in the day when connecting your computer to a network definitely wasn’t what the cool kids were doing. [Thanks Larry]

    Super Affordable LED Lighting Ready to Go Off Mains Voltage

    lights

    If you’re looking for a super cheap way to add LED lighting accents to your house, then this hack is for you! Corn-cob style LED light bulbs can be had for a few dollars. The bulbs include driver circuitry, and 8 LED arrays! All you have to do is take it apart.

    [Martin Raynsford] stumbled upon this idea when trying to think of a way to light his laser engraving enclosure. It originally came with a regular light bulb, but it didn’t distribute light nicely and was in the way for some of his other planned upgrades.

    Not wanting to add another DC power supply to the mix he remembered an old corn-cob LED light bulb he had — as it turns out, they’re pretty easy to take apart! Solder some longer leads on (take note of how they are wired, some are in series, some in parallel) and you’ve just made yourself some easy to use LED accent lighting!

    Of course you could just buy those cheap LED rolls from China nowadays for next to nothing for your accent lighting.

    Hackerspace Tour: IXR in Wall, NJ

    IXR2

    Hackaday took a little trip out to Wall, NJ last weekend for the Vintage Computer Festival 9.1 East. The event was held at Camp Evans, a former US military installation that can only be described as, ‘The DARPA of a century ago”. This is the site of a Marconi transmitter and the place where [Edwin Armstrong] developed the regenerative receiver a little more than 100 years ago.

    There’s a lot more to Camp Evans than a vintage computer festival once a year – it’s also home to MARCH, the Mid-Atlantic Retro Computing Hobbyists, InfoAge, a retro technology museum, and IXR, the Institute for eXploratory Research, a hackerspace located in the old telecom building at Camp Evans.

    In our video tour, [Joe Wilkes] takes us around the shop, showing off their equipment and tools. Unlike most of our hackerspace tours, we couldn’t find a Makerbot sitting disused on a bookshelf anywhere, but the space did have a Solidoodle 3D printer, a Shapeoko 2 CNC machine under construction, and enough hand tools to bring any project to fruition.

    There were a few oddities in IXR compared to the other hackerspaces we’ve been to. First is an inordinate amount of synths, keyboards, and other MIDI gear. [Joe] didn’t know what these were for, so we’ll leave that explanation for an IXR member in the comments of this post. There was also a small supply of random components for sale (and on display). Most of the merch was from Adafruit, and it seems like a great way to have that one part I need to finish this build for members while providing a little bit of beer money for the space.

    Desktop Sized Tamagotchi Is Even Harder to Ignore

    desktop tamagotchi

    [Vadim] was feeling a bit bored at work one day and dreamed up this rather odd project. He had a spare LED matrix handy, and thought, “I should build a giant Tamagotchi…” and so he did.

    In case you’re not aware, Tamagotchi’s were digital pets introduced in the late 90′s. You had to feed them, play with them and even train them — attempting to teach the responsibility of having a real pet. It was a bit of a fad, and to be honest, they were really quite annoying — but that didn’t stop [Vadim] wanting to make his own!

    He’s using an ATmega328P with the Arduino boot loader at the heart of this project. The LED matrix is made of a group of four 8×8 LED modules with four shift registers (74HC595) and two Darlington transistor arrays to take the current — This is because the 256 LEDs need to be multiplexed down to 32 IO’s (16 rows + 16 columns).

    Once the hardware was all done, he started coding — he’s actually coded the entire game from scratch, and while it’s not that complex it’s still an impressive amount of effort that went into this desktop sized Tamagotchi!

    To see it in action, stick around after the break.

    To learn more about hacking a Tamagotchi, there’s an excellent talk about how to reverse engineer it that we covered a few years ago.

    Printing In Three Dimensions, For Real This Time

    topo

    3D printers don’t continuously print in three dimensions – they print one layer, then another, then another. This is true for every single 3D printing technology, but now Topolabs has a very interesting technique that changes that. They’re printing in three dimensions by moving in the Z axis while also printing in the X and Y axes.

    The basic idea behind Topolabs’ software is to print a support block, then print an object right on top of the support. The support block can be curved and convex, and the finished product follows the contours of the solid support block. Unlike ‘printing with supports’, the printer extrudes along the X, Y, and Z axes, which should make the finished product much, much stronger.

    There are a few drawbacks to the technique – a release agent must be applied to the top of the support block. In the video below, Topolabs is using Kapton, but hair spray or glue sticks will also work. There’s also a limit to how steep an incline a printer can print, determined by the size of the extruder nozzle. Lastly, this technique would be much better suited for a delta-style bot, but the team is getting very good results with a normal Cartesian bot.

    You can see a few videos of the Topolabs printing technique below.

    The Ultimate Workstation That Folds Up

    ultimate maker station

    Looking for an easy way to keep on making stuff even though you’re living in a tiny dorm room? [Matt Silver] was tired of not having a dedicated work-space, so he spent some serious time designing this modular, re-configurable and collapsible portable workstation ready for almost anything.

    He started out by sketching ideas, playing around with 3D models in SketchUp, and eventually building a few prototypes using trial and error — and what he’s come up with is pretty darn impressive. It folds down to just under a foot by three feet squared and has casters to roll it around. Once unfolded, you stabilize it by placing your chair on one of the walls that folds down, and the desk itself is also re-configurable for different work surfaces. He’s included a power bar, an LED work-light, and it even has storage racks for tools on the side.

    It’s a very thorough Instructable, and definitely worth a look through — especially to see how it magically unfolds! And if you’re wondering about how much it would cost to build, you’re probably looking at around $200 depending on what you already have on hand. What we really like is how it’s almost entirely made out of a single 4′x8′ panel of plywood — it’s like this guy works for IKEA or something!

    Sewing Conductive Thread in Parallel Lines

    sewing-parallel-lines-conductive-thread

    [Cynthia] has shared a great video of  machine sewing parallel lines of conductive thread onto ribbon using a cording foot which usually comes standard with most machines. This technique could be particularly useful when using addressable LEDs like a NeoPixel to get the ground, data, and positive lined up fairly accurately. Sewing the conductive thread onto ribbon also makes it a hell of a lot easier to attach to many garments or textiles,  and also makes it easier to replace or reuse.

    The method is pretty easy, essentially using the grooves in the cording foot to guide the conductive treads and ensuring even spacing. Two of the lines are sewn down approximately 3 mm apart using a zigzag stitch. The third line is sewn separately making sure the stitching doesn’t break the first two lines. In the video, a striped ribbon is used which has slight troughs that additionally helps the threads stay in place and the sewer to stay on target.

    [Cynthia] of Cynthia Designs Studio has been experimenting with embedding electronics in textiles and has quite a few great videos that you can check out on the Cynthia Designs Studio YouTube channel.

    We have seen a machine embroidered LED matrix and a hand sewn LED quilt here on Hackaday, but those who have tried know that conductive thread can be very tricky to work with and keep conductivity.  Do you have any tips or tricks for hand or machine sewing conductive thread? If so, please share in the comments below.

    Turn Your Drill Press into a Bobbin/Spindle Sander

    drill press ander

    Drill presses are a staple tool of the typical garage — they aren’t too expensive and are indispensably useful — but have you ever thought of turning it into a spindle sander?

    You can buy drum sander kits fairly cheap, but the problem is they’re really difficult to use and really messy too — you’ll have sawdust everywhere in no time. What [Carl's] done here is created a wood box for his drill press with different size holes for each drum sander bit. By attaching a vacuum cleaner to the box, you can clean up your mess while you’re still doing the work.

    Just a note — drill presses aren’t designed to take radial loads like a mill is. If you’re planning on doing some really heavy sanding, adding a bolt through the entire drum sander bit and then coupling it with a fixed bearing inside of your box might be a good idea.

    It’s a pretty simple hack, but could save you an additional power tool, and space on your work bench! Have a drill but no drill press? No problem.

    A Virtual Cane for the Visually Impaired

    cane

    [Roman] has created an electronic cane for the visually impaired. Blind and visually impaired people have used canes and walking sticks for centuries. However, it wasn’t until the 1920′s and 1930′s that the white cane came to be synonymous with the blind. [Roman] is attempting to improve on the white cane design by bringing modern electronics to the table. With a mixture of hardware and clever software running on an Android smartphone, [Roman] has created a device that could help a blind person navigate.

    The white cane has been replaced with a virtual cane, consisting of a 3D printed black cylinder. The cane is controlled by an ATmega328 running the Arduino bootloader and [Roman's] code. Peeking out from the end of the handle is a Maxbotix ultrasonic distance sensor. Distance information is reported to the user via a piezo buzzer and a vibration motor. An induction coil allows for charging without fumbling for tiny connectors. A Bluetooth module connects the virtual cane to the other half of the system, an Android phone.

    [Roman's] Android app runs solely on voice prompts and speech syntheses. Navigation commands such as “Take me to <address>” use the phone’s GPS and Google Maps API to retrieve route information. [Roman's] app then speaks the directions for the user to follow. Help can be summoned by simply stating “Send <contact name> my current location.” In the event that the user drops their virtual cane, “Find my device” will send a Bluetooth command to the cane. Once the command is received, the cane will reveal its position by beeping and vibrating.

    We’ve said it before, and we’ll say it again. Using technology to help disabled people is one of the best hacks we can think of. Hackaday alum [Caleb Kraft] has been doing just that with his work at The Controller Project. [Roman] is still actively improving his cane. He’s already won a gold medal at the Niagara Regional Science and Engineering Fair. He’s entered his project in several more science events, including the Canada Wide Science Fair and the Google Science Fair. Good luck [Roman]!

    Developed on Hackaday: The Top PCB dilemna

    The Hackaday community offline password keeper is slowly coming together. A few days ago we received the top PCB for Olivier’s design (shown above). If you look at the picture below, you may see the problem we discovered when opening our package: the soldermask was the wrong color! Given the board is meant to be placed behind a tinted acrylic panel, this was quite a problem…

    After using some spray paint, we managed to get to the point shown in the bottom left of the picture. The next task was to find the best way to illuminate the input interface with reverse mount LEDs. Using a CNC mill we machined openings (top right PCB) but also removed some epoxy on both PCB’s sides, thinking it would provide a better light diffusion. We then wrote part of the Mooltipass PWM code and took these pictures:

    Using the FR4 to diffuse the light

    Cut through openings

    We hope you agree that the ‘FR4 version’ looks better. The other version, which has the cut openings, illuminates unevenly because the smartcard isn’t under all of the LEDs. This raises several questions that we hope our dear Hackaday readers can answer:

    1. Can this kind of machining be done in standard PCB fabs?
    2. Instead of leaving the bare FR4 on top, should we cover it with white soldermask?
    3. Instead of leaving the bare FR4 on top, should we cover it with white silkscreen?

    Keep in mind that we would only need to machine one PCB’s side.

    Another concern is the top panel. As previously mentioned we’re currently using a tinted acrylic panel, which may not be the best solution to prevent scratches. We’re thinking to use glass in the future (corning gorilla glass?) so we may also hide everything around the display’s active area. Do you guys have any experience with this? Would it be expensive in relatively small quantities?

    As you can see, we still need to find the best compromises and we hope you can help us. Please post a quick message in the comment section below or contact the team in the official Mooltipass Google Group.

    DIY Linear Actuators For A Flight Sim

    linear

    [Roland] has already built a few very cool and extremely realistic flight sims, but his latest project will put his current rig to shame. He’s building a six degree of freedom simulator based on homebuilt linear actuators of his own design.

    The actuator is powered by a large DC motor moving timing belts along the length of the enclosure. These timing belts are connected to a shaft that’s coupled to the frame with a few bungee cords. The bungee cords are important; without them, the timing belts would be carrying all the load of the sim – not a good thing if these actuators are moving an entire cockpit around a living room.

    Also on [Roland]‘s list of awesome stuff he’s building for his flight sims is a vibration system based on the BFF Shaker. This board takes data in from sim software and turns it into vibrations produced by either unbalanced DC motors or one of those ‘bass kicker’ transducers.

    It’s all very cool stuff, and with all the crazy upgrades [Roland] is doing to his sim rig, he’s doing much better than paying $300/hour to rent a Beechcraft Baron.

    Transcribing Piano Rolls with Python

    Piano Roll

     

    Perforated rolls of paper, called piano rolls, are used to input songs into player pianos. The image above was taken from a YouTube video showing a player piano playing a Gershwin tune called Limehouse Nights. There’s no published sheet music for the song, so [Zulko] decided to use Python to transcribe it.

    First off the video was downloaded from YouTube. This video was processed with MoviePy library to create a single image plotting the notes. Using a Fourier Transform, the horizontal spacing between notes was found. This allowed the image to be reduced so that one pixel corresponded with one key.

    With that done, each column could be assigned to a specific note on the piano. That takes care of the pitches, but the note duration requires more processing. The Fourier Transform is applied again to determine the length of a quarter note. With this known, the notes can be quantized, and a note duration can be applied to each.

    Once the duration and notes are known, it’s time to export sheet music. LilyPond, an open source language for music notation, was used. This converts ASCII text into a sheet music PDF. The final result is a playable score of the piece, which you can watch after the break.

    This Is Not Your Father’s Power Wheel

    powerwheels-mainIf you had a Power Wheel vehicle as a kid you may have been the envy of the neighborhood. Even as fun as they were you probably out grew them. Lucky for a few youngsters, [Bob] hasn’t. Not only does he have several Power Wheels for his children to use, he does some pretty cool mods to make them even more fun.

    Changing the stock motor out for a cordless drill is one of the first things that gets done. A few brands have been used but the  Ryobi 18v Cordless Drill is the favorite. The entire drill is used, including the reduction gearbox. The gearbox is switched to LOW gearing so that the drill has enough torque to move the combined weight of the vehicle and child. As much as it may sound odd to use a drill in this manner, the Power Wheel can get up to about 15 mph. A stock Power Wheels maxes out at 5 mph

    The stock Power Wheel ‘gas’ pedal is a simple on/off switch and may have one or two speeds. It’s replaced by the variable speed trigger switch from the drill giving the tiny driver full control of the speed. In most cases the batteries that came with the drill are responsible for supplying the necessary electrical power.

    Plastic wheels aren’t going to cut the traction mustard. These are upgraded to rubber tires and metal wheels like the ones you would find on a rider lawn mower. Not only are the rubber tires much quieter than the originals but they give superior traction that can handle rain, snow and steep hills.

    So how do all these mods hold up over time? [Bob] says some of his modded Power Wheels are still working after 2 years of regular use. There are several different conversions on his site so head over and check them out.

    Play Peek-A-Boo with Blind Spot

    blindspot

    You’re at a concert, and a car filled with balloons is in a glass box. As you approach the box, vertical blinds close to block the view directly in front of you. You move left, more blinds close to block your view. The blinds follow your every move, ensuring you can’t get a close up view of the car inside. You’ve just met Blind Spot, an interactive art installation by [Brendan Matkin].

    Blind Spot was presented at Breakerhead, an incredible arts and engineering event which takes place every September in Calgary, Canada. Blind Spot consists of a car inside a large wooden box. Windows allow a view into the box, though there are 96 vertical blinds just behind the glass. The vertical blinds are individually controlled by hobby servos. The servos are wired to six serial servo controllers, all of which are controlled by an Arduino.

    A PC serves as Blind Spot’s brain. For sensors, 6 wide-angle webcams connect to a standard Windows 7 machine. Running 6 webcams is not exactly a standard configuration. To handle this,  [Brendan] switched the webcams to friendly names in the windows registry. The webcam images are read by a Processing sketch. The sketch scans the images and determines which of the 96 blinds to close. The code for Blind Spot is available on github.

    ISPnub – A Stand-Alone AVR In-System-Programmer Module

    [Thomas] tipped us about his latest project: a stand-alone AVR programmer module named ISPnub. As you can see in the picture above, it is a simple circuit board composed of a main microcontroller (ATmega1284p), one button and two LEDs. Programming a target is a simple as connecting the ISPnub and pressing the button. The flashing operation success status is then shown using the green/red LED.

    ISPnub gets its power from the target circuit so no external power supply is needed. It works over a wide voltage range: 1.8V to 5.5V. The module also features a programming counter which can be used to limit the number of programming cycles. A multi-platform Java tool is in charge of embedding the target flash contents with the ISPnub main firmware. The complete project is open source so you may want to check out the official GitHub repository for the firmware and the project’s page for the schematics.

    Using Bitcoin To Detect Malware

    vigil

    Now that you can actually buy things with bitcoins, it’s become a playground for modern malware authors. [Eric] recently lost about 5 BTC because of some malware he installed and decided to do something about it. He came up with BitcoinVigil, a web service that constantly looks at bitcoin honeypots and alerts you when bitcoins are surreptitiously removed.

    The idea behind BitcoinVigil is to set up a Bitcoin wallet with a small amount of coins in it – only about $10 USD worth. When modern, Bitcoin-seeking malware is run on a computer, it looks for this ‘moneypot’ and sends an email out notifying the owner of the coins to stolen money.

    [Eric] was at a LAN party a few weeks ago and ‘borrowed’ a friend’s copy of Starcraft 1. Just a few seconds after installing it, he received an alert notifying him about a few stolen bitcoins. This time [Eric] only lost a few microBTC, but better than the thousands of USD he lost before.

    Google Releases Project Ara MDK

    Ara Modules

     

    It’s been a little while since we’ve heard about modular smartphones, but Google has just released the Module Developers Kit (MDK) for Project Ara. The development kit gives an overview of the inner workings of the project, and provides templates for building your own modules.

    Once you’ve agreed to the license agreement and downloaded the MDK, you’ll find a large specification document. It explains how a phone will comprise of many modules loaded into an endoskeleton, giving mechanical support and electrical connections. An interface block provides each module with power and data over LVDS. Modules are held in place by an electro-permanent magnet which can be toggled by software.

    When you’re finished with the specification document, you can dive into the reference designs. These include templates and actual modules for WiFi, thermal imaging, a battery pack, and more. Mechanical CAD is provided as STEP files and drawings, and electrical design files are provided as Altium projects and PDF schematics.

    We discussed both Project Ara and Phonebloks on Hackaday in the past, but now we’re starting to see real details. Google’s Project Ara Developer Conference takes place on April 15th and 16th, and you can register to take part remotely for free. Is this the start of an open, modular phone? Let us know what you think.

    [Thanks to Adam for the tip]
