 IDE to NDS Connection

Published on 2006-09-09 - by Alexei Karpenko, ©Alexei Karpenko

To get back to hardware development, I decided to do a quick IDE to GBAMP (GBA Movie Player v2) hack. I also took a few pictures for the few people interested in doing this (at their own risk) :)

You might not know it, but CompactFlash memory cards use IDE interface; and hence it’s possible to map each IDE pin to a corresponding CF pin. Unfortunately, DS delivers only 3.3V to GBA slot and so an external 5V power supply is required. I used a 11.1V li-poly battery and a DC-DC converter to bring the voltage down to 5V.

 Xbox Laptop 360

Published on 2006-09-10 - by Ben, ©Ben

A friend of mine asked back in May Can you build an Xbox 360 laptop? And I responded Sure, can you pay for it? He agreed, and thus I set forth on what was surely to be my most complex and insanely ridiculous videogame project yet. (I say videogame project as I highly doubt I’ll ever manage anything as complex as Port Washington again, though at times this project sucked my will to live about as much)

With my first batch of "venture capital" in hand I ran off to the nearby store to get myself an Xbox 360 Super Package, or whatever the $400 version is called. While I won’t mention the game store I stopped at by name, I will recreate the amazing conversation I had with one of their employees...

 DS Lite Replacement Case Tutorial

Published on 2006-09-10 - by Karl B., ©Content Holdings, LLC.

Painting your DS Lite is a good way to show your individuality, but it’s just so easy to mess up. That’s why replacement cases are really popular these days. You can just pick out a design or color that you like, and if you have the money, you’re pretty much good to go. The only hard thing about it is the actual case replacement part. Not all of us are good with their hands, and sometimes the sheer thought of taking a screwdriver to your DS Lite and taking it apart when you’re not a Nintendo-certified DS Lite tech is enough to make some people break down with fear and guilt.

Alright, we’re exaggerating. Maybe. Who knows, there really might be people like that out there in the wide blue yonder.

 eLoader 0.98 "Porter" - 2.0+ Homebrew for PSP without GTA!

Published on 2006-09-05 - by Pranav T., ©Content Holdings, LLC.

We’re sure you guys would be really itching to know what Fanjita and Ditlew have been up to lately. There hasn’t been an eLoader release for quite some time. The last one, if we recall correctly, was on the 2nd of April which bundled in WiFi support. After that, the 2.XX homebrew scene had been quiet for a while...That is, before the onslaught of downgraders! Although they might have taken a bit of shine off the eLoader with the masses moving to 1.5 firmware for kernel mode homebrew, I know a lot of people who stayed with the eLoader, anticipating great things.

And the Noobz crew isn’t one to disappoint. How about I tell you that you can skip buying that GTA UMD for using homebrew on 2.00 and above! Using the recent TIFF exploit in all the higher firmwares, Fanjita and Ditlew have been able to "port" the eLoader to the TIFF exploit. Earlier, homebrew on higher firmwares was run using the savegame exploit by Edison Carter. Now, rather than wasting time by starting GTA every time you want to use homebrew, you can simply go the the Photo section and start the eLoader. Heck, it’s actually faster than even 1.0/1.5 homebrew since you don’t have to view that "flashing bulbs" video. And the best part is that it doesn’t matter whether you have a TA-082 PSP or not, you can play homebrew regardless!

 Modified NES (in progress)

Published on 2006 - by pixelform, ©pixelform

In early June I was contacted via email with a request to modify an NES game console for use as a visualizer for chiptunes based music performance. I accepted and have made some incredible progress over the past few days. I’ve already completed the manual bends and have pretty much solidified the circuitry that will be handling the audio reactivity. Below are links to images and video taken through the process.

Most of the bends are taken from the 9049A chip that is labelled "sram(vram)". The "schematic" image-003 shows an abstraction of how I sussed out bend points and features this chip. Filled in bubbles on the schematic indicate duplicate points found on the "sram(vram)" chip. The points left open do not effect the video or are unstable (case a crash). The points with dashed above or below them are used as bend points and each is unique. The way I’m using the rotary switches is similar to leaving the the device open and sweeping a wire along pins. 9 points each from the circuit board are wired up to each of the rotary switches outer lugs. The inner lugs are wired up to toggles that connect the two selected points on either rotary switch. By holding one rotary still and rotating the other you are essentially sweeping a contact from one pin across 9 others.

 NES Controller TV Remote

Published on 2005-09-03 - by leadingzero, ©leadingzero

Ever wanted to control your TV with an old school Nintendo controller? No? Well, I have and now I do. A few weeks ago I picked up an old school Nintendo controller from eBay and began thinking of a project for it - then it hit me! Controlling the basic functions of my TV through a NES pad would not only be awesome, but it would make me one step closer to that darned Captain-N.

 Interfacing with the PSP Remote port

Published on 2006-06-16 - by NIL, ©NIL

As already revealed here and here, the Remote port of the PSP™ is in fact a serial port, and the remote is being handled through a standard RS232 protocol, albeit using [0,+2.5V] voltage instead of [-12,+12V]. Therefore the question is; is it possible to connect the PSP™ remote port to a PC serial port? The answer is yes! Of course, you can NOT plug a PSP™ directly into a PC serial port (unless you want to fry it beyond repairs), but with a simple serial line converter this is no trouble at all, and you can then exploit a standard serial port out of the PSP™.

 PowerBook disassembly

Published on 2005-10-21 - by Wil Harris, ©Bit Publishing Ltd.

Regular readers will know that the majority of my day is spent attached to my beloved Apple PowerBook™. A 1GHz G4 machine with 768MB of RAM and Radeon 9600™ graphics, it's my daily workhorse, despite the prevalence of high-powered PC workstations round here. Why? Well, it's all about OSX™, for me.

My PowerBook™ goes with me absolutely everywhere. It's been around the world more times than I can count, to innumerable Starbucks™ coffee houses, to parks, gardens, exhibitions - everywhere I think I might be able to find 5 minutes to answer email.

However, those who know me will also know that I'm not the most careful of people. I can be clumsy and more than a little reckless on occasion. It was not an entirely unexpected event, then, when my PowerBook™ decided to give up the ghost.

 Fast robot prototyping

Published on 2005-10-04 - by Erik Zoltan, ©International Business Machines Corporation

The previous article, How to drive your wireless robot, covered the use of servo controllers and how to modify a servo motor for continuous rotation. This gives you a good starting point for actually building a "base" robotic system. I want to continue the bottom-up approach of creating integrated subsystems and assembling them together without any real idea of what the final product will look like, which was described in my inaugural article, A recipe for success in wireless robotics.

In this article I want to show you how to actually prototype a wireless robot. I'm going to take you through an initial prototype I developed in a couple of hours, and then show how I took this prototype to the next level using sturdier building materials.

 How to drive your wireless robot

Published on 2005-10-04 - by Erik Zoltan, ©International Business Machines Corporation

The previous article in this series, A recipe for success in wireless robotics", covered bottom-up design as a proposed methodology for wireless robotics. Taking that as a starting point, I want to begin this article by examining the question of what to build first. In bottom-up design, this is a matter of "finding the bottom," so you need to figure out what the dependencies are between systems. You want to avoid painting yourself into a corner.

It turns out that you should start with the computer, the motor controller, and the motors. I'll cover some of the considerations that you should be aware of when selecting these components and integrating them together. Resources points you to more information about specific hardware, which you can use to help you make your decisions.

This article is part of an ongoing series of articles on building an open source wireless robot. Object-oriented software design makes it possible for many different robots to run the same code, even if they have different hardware, different operating systems, and so on. I want to be able to write high-level navigation code that could run on a wheeled Linux™ laptop robot or a legged robot controlled by a handheld computer running a different operating system. Future articles will build on the components covered here.

 Recipe for success in wireless robotics (A)

Published on 2005-08-02 - by Erik Zoltán, ©International Business Machines Corporation

This is the first in a series of articles on wireless robotics. The first group of articles will take you through the process of building an actual wireless robot component by component. I'll cover a number of variations on each component. You can use these articles as a guide to build your own wireless robot, or you can simply read them to learn about the field at an informational level.

After I've completed the process of building a wireless robot, future articles will cover the field at a more advanced level, using these initial articles as a base. I'm going to cover a variety of approaches you can take when building a robot, so you won't be one stuck building any one specific robot. I don't know exactly what my own robots will look like yet, but I'm pretty sure there will be more than one of them. (That might sound odd, but it will make more sense after I've described the methodology.)

This introductory article focuses on methodology. Before I get to the actual building process itself, I want to let you know about the general approach I will take toward these articles. First will be some good advice for robotics in general, and wireless robotics in particular, but the column is also customized to this particular context of articles published on developerWorks. A large team working on a specific project with a specific deadline would certainly take a different approach.

 Investigations into Socket 939 Athlon 64 Overclocking

Published on 2005-10-03 - by Jarred Walton, ©AnandTech, Inc

This article is an in-depth look at overclocking. We'll cover how to do it, what sort of performance you can achieve, problems and potential solutions, etc. Overclocking can be frustrating, rewarding, fun, and dangerous. We don't mean burn the house down dangerous, but you could certainly end up ruining some or all of your computer components. We take no responsibility for any difficulties or losses you may experience by using the information in this article, and we certainly take no responsibility for any damage that may occur to any person, place, or object. The manufacturers of the parts that we are using are also not accountable for any loss/damage that may occur - most companies void your warranty for overclocking. It's a risk, and it's your risk - proceed with caution. Finally, overclocking is never a "guaranteed result". You may or may not match the results that we achieve. We'll be happy to offer suggestions if you need them, as will many of our forum members. Patience and research are part of overclocking as well, so please understand that you may have to do some work on your own. If you can accept those warnings, we hope that you enjoy this article.
