Hey everyone, I wanted to announce my new Electronics and PCB Design course on Udemy. I worked on it for 18 months and tried to create something that would enable people to learn electronics and PCB design in a single course, have fun, and not be overwhelmed by math and too much theory. The goal of the course is to teach electronics both theoretically, but practically as well with lots of bench work. And then once the fundamentals are learned, we dive into PCB design from schematic to manufactured PCB. Those that are interested in building add-on boards for various retro system, but haven't made a PCB, then this is perfect for you. Also, those that "hack" electronics, but want a deeper understanding of analog, filters, amps, and circuit analysis, you will find this course helpful without needing a Ph.D in math Here's the information, links, and discount code... (along with some images of project developed in the course; PCBs, simulation, bread board work). Crash Course Electronics and PCB Design @ Udemy -- 135 lectures, 87 hours. 50% Discount Code HAL9000 https://www.udemy.com/crash-course-electronics-and-pcb-design

In my effort to provide documentation for lynx, I've started a new task : "vectorisation" of the Atari Lynx Schematics. I've done it with KiCAD. The schematics are based on the 4 part of Atari Lynx Hardware Schematics This is not the "final" version. Some parts were hard to read/understand. If you see any mistake, please feel free to report it. Schematics v0.1.pdf

ElectronicSentimentalities http://electronicsentimentalities.com/InstallationServices.html Spectacular...If I had to choose one word to describe both my dealings with and the end results of the service that ElectronicSentimentalities offers, spectacular would be that word. I have had the pleasure of purchasing and currently own the Best 7800 Composite mod system, a 7800 system mod from Yurkie, and now one from ElectronicSentimetalities. Yurkie was dead on the money recommending their service after discontinuing the one he provided. The recommendation meant a lot to me, knowing how satisfied I was and how awesome Yurkie's work was on the 7800, for him to recommend another - I knew it had to be good. I was wrong. It is not good, but excellent. Joe was friendly, fast, and a pleasure to deal with; including shipping my console back way before the expected return date. Further, the price is extremely reasonable. You get S-Video, Composite, and audio out jacks. The composite picture is the clearest I have seen and the S-Video is even more stunning. Being that I own a "CPS 7800 Diagnostic Test Cartridge'', the console was tested, and the color calibration was shown to have been performed perfectly as well. The console was packaged very carefully when sent back including a second box with padding/insulation in addition to the one I utilized sending my system out. Externally, you could not tell (Outside of the new connectors) the system was even touched. In fact, it was wrapped nearly exact the way I shipped it. You're not a DIY console mod person or not very good at it; or just want the ease and convenience of having your 7800 system mod done beautifully and professionally with spectacular results, this would be the place your console needs to go. Highly recommended and highly impressed - Bravo, Joe/ElectronicSentimentalities.

So here's a situation I found myself in last week. I was enjoying a nice game of Moon Patrol on my newly-acquired Atari 5200 when the 1, 2, 3, and Start buttons all decided to stop responding. At first it was intemittent, depending on the angle at which I had the controller held, but then it got to the point where it wouldn't work at all. So I do some quick research, find that the 1, 2, 3, and Start buttons on the 5200 controller are all tied to Pin 7. I open up the controller, find the red/white wire for pin 7 and do an end-to-end continuity check. Nothing. All the other wires were fine, though. So I start incrementally checking the red/white wire as far as it's exposed leading up to the cable's collar, and it's whole. Unwillingly, I carefully trimmed off the collar and continued checking the wire, hoping to find the break very close to that end. Still nothing--I've got continuity to over 2 inches past the collar. Crap. So then I start checking continuity at the plug end. By that point, it's getting messy; I've already made several surgical incisions to expose the red/white wire for testing, and I STILL hadn't found the break. FINALLY, I go back to the controller end of the cable, cut back the wrap another 3 inches and THEN I find the break in the wire--some 5 inches down from the collar. What rotten luck, even by 5200 controller standards. So I'm able to patch it back up and get it working again, although by the time I had to tape all the cuts back closed, it truly looks like a ghetto controller. But the whole situation got me thinking--was there an easier way to find the break without having to make all the exploratory incisions in the cable? I know that there are wire break detectors commonly used by owners of buried invisible fence lines which use something like an AM radio signal using the suspect wire as an antenna and a receiver to figure out the approximate location of a the break. But is there anything that works at a much smaller (and therefore more precise) scale? What I'm thinking is a device that you hook to one end of the wire and emits a simple square wave over a radio frequency, and then have a receiver which picks up the tone as you move it along the cable (presumably, the tone would change once you pass the break). But I have no idea if that would work on the scale of locating a break within an inch or so. Has anyone run across a similar problem for which they've found a solution? It's pretty much a moot point for me now since the damage is already done. But I'm intrigued by the challenge of coming up with a more elegant way of addressing the problem should I run across it again in the future.

I'm new to classic computing since I've only been collecting video games and haven't gotten into the computer game craze yet. The Qs: Q1# What are some of the best spectrum games to buy at first and how much should I pay for each? Q2# How much should I pay for a Commadore 64 with all the hook ups or complete in box?

Ah, promo material.. It takes so long to put together, sometimes. Such is the case with my myspace page for my dj profile. Took about six hours yesterday to get the thing sorted out, the whole process consisting of compiling promo mixes on my harddrive, to uploading them to a variety of distribution sites, to creating new artwork to be used as album covers, to uploading varius phots to the photobucket, then linking them into the myspace profile, to creating blogs to link to with each promo album, etc. etc.. Such a long, drawn-out process, but maybe it's something I should have done right from the start when I started my music page nearly two years ago. Oh well, I'm not exactly known for thinking that far ahead.. Ya live and learn, I suppose. Anyways, to add a shameless plug on to this, I have a new promo DJ mix available on my MySpace music page (http://www.myspace.com/djaustinmusic). I spin breaks/breakbeats--music that goes excellent with gaming--so if anyone is interested in a free promo CD, PM me and I will gladly mail one to you. Otherwise my mixes are available to download on the myspace. Even more details (or just me essentially saying this in person) can be seen at my YouTube video I just uploaded: http://www.youtube.com/watch?v=mGZMPcK1nA4 Now since that's done, I can relax a bit and get back to playing Gauntlet: Seven Sorrows on the original XBOX. I'm actually borrowing my brother's copy, and it's been sitting in my collection for about eight months now, waiting to be played. I've actually been a little hesitant on playing it, for one reason or another.. Honestly, I don't even know the reason. Lack of motivation, I suppose. Sometimes that happens with games and I. I think one thing that kicked-start me into finally popping it in is that I read John Romero had a hand in making it. I don't usually play games based on names associated with them, and Romero especially has had a rocky career since he left ID, but there's that little bit of hope that I suppose sits in my mind sub-consciously--DOOM and Quake are still some of my favorite and absolutely most-played games of all time, after all. Also, asides from that, I was a huge fan of Gauntlet Legends and Dark Legacy. I probably spent hundreds of dollars perfecting Legends in the arcade.. There was a point where I managed to get each character up to level 99 and finished it the most amount of times, solidifying my place on the number one leader board slots for each type of character on the machine (Man, I wish that arcade was still open and didn't get rid of that unit).. So needless to say, I think it was about time I finally gave it a shot. I went into it not expecting anything, but I was pleasantly surprised that it is actually more similar to Legends/Dark Legacy than not. It uses a similar form of 3D visuals for the environments, there are still the usual projectile shots, and hoards of enemies come at you via the spawners. Overall, I'm satisfied *enough* with it, but I think it fell short of the greatness (or at least addicting factor that Legends had). I have many reasons for this. For one, the requirement of projectile shots being a vital part of a successful gameplay run are zilch in this one. In the original Legends, it was really necessary to use them as much as possible, using them to take out frequent bomb throwers or kamikaze enemies, or to destroy bosses. In this one, the projectile shots are so weak there is no point in using them, and with the multiple melee attack modes and moves that always put you in a defensively sound position (for instance, the purchased A then X button attack with the Warrior), projectile attacks are ONLY used when there is an archer perched on a ledge you can't physically get to. Second, the boss battles don't feel like boss battles, compared to the arcade games, anyway. Many of the bosses are roughly the same size as the mid-level golems in Legends, so needless to say, it's not quite the same as fighting the nearly full-screen bosses of Legends and Dark Legacy. Third, the sizes of the stages seem quite small compared to Legends. This is probably either due to easily being able to smash through spawners and hordes of enemies quickly, or the fact that the world is quite detailed, going far, far into the visible distance, leaving the XBOX not much to do in actually expanding the size of the playable levels. There are a few other details that I think could have been worked on or changed, but overall the game is still an enjoyable mash-fest. There's not much technique involved like there was in Legends (in order to survive on the one quarter), but I think it's entertaining. I haven't finished it yet nor do I have the ability to play it in multiplayer, but I've gotten a kick out of it so far (I'm up to the fifth sorrow right now--each "sorrow" being a boss--out of seven, so provided there's not anything after that, then I'm close to the end of the game already, having only played it for a couple of hours). I may recommend checking it out if you're a fan of Gauntlet Legends or Dark Legacy. I don't think it's going to have the replay value of the prior, as the max level cap for your character is 20, but nonetheless, it seems like it's enjoyable for a playthrough or two. **EDIT: After writing this, I popped in Gauntlet to continue playing, and guess what? All of my special attacks, items, etc. were wiped off of my character. Autosave was on when I was playing last, so I know I've just experienced a very, VERY piss-poor design choice.. It's damn near-impossible to finish the stage I am on (apparently 68% through the game) with all of my abilities stripped from me. Who's crackhead decision was this?? With this in mind, my verdict on this game has changed: If you don't plan on playing it straight through in one go, then you're best off passing on this one.
