    Well, the MegaDrive 2 has an ASIC containing the CPU and audio chip. One of the pins define the video signal is at 60 or 50Hz the other is for the language, Japanese or "International". So, you cut the tracks going to those two pins, get the +5V and GND signals elsewhere. Depending on the...

    Not much, I have to concede ;) But it's far enough for a bunch of SMD components. My board only has a STM8S, a SWIM connector, some "large" pads to solder kynar wires, a dual pin connector, a bunch of resistors and capacitors, an rgb led and a few SMD transistors. That's all what's needed for...

      It's from OshPark, they charge 5$ per square inch, you get three copies and free shipping. My board design is a bit smaller than a square inch. I bet there are cheaper per square inch PCB factories. But they often have a minimum number of boards, so it's actually cheaper to pay more per inch...

    Great to see that your project is coming along. A zikzak "cube" would be sexy as hell  :P I've started playing with STM8S003K3, quite a nice chip! I was surprised to discover that a value line product has so many integrated peripherals :D (3 timers, 5 channel ADC, SPI, UART, I²C and off...

    It's an oscillator, the large 4 pins rectangular "tin box"… And yeah, they're indeed more expensive than crystals. For four pieces, I almost paid 4$. I guess I could have done some researches to use the video chip with a crystal and some resistors. But it's easier to use an oscillator and...

    I'm still lurking around and I would be interested by a more polished product than this first revision. Right now I still have those old unfinished projects, but started yet another one (quite simple, I only want to make it extra clean) :P That new project is modding my MegaDrive : I've...

    100% agree… I think that in "card trading" games it's even more complicated than in other kind of games. That's why we're not planning on the long term right now, we go for the fastest implementation. Getting thing done quick and dirty keep our motivation high, since we can see some...

    I feel that OOP makes dev easier when you're not alone in a project.That way I can work on a class while someone else is working on another without any trouble. We're starting really small and simple. As time passes, we will make it more and more complex. I don't want to spend weeks planning...

    I bought and received a SMT8 "dev board". The board has the footprint of a wide DIP32 chip, it has a STM8S003K3, a SWIM connector, an integrated voltage regulator, unpopulated holes for a crystal oscillator and of course two rows of pin headers. Pretty neat IMHO. I still have to launch windows...

    Since people are going to use that elevator, I want to make it as safe as possible, so IMHO wireless isn't an option (and it's pricey!). The main board won't be that far from the electric winch, so I'd rather use a transmission support that won't get completely scrambled when the winch is in...

    Well, he wants to learn programming and I want to try teaching (even if I'm not great at programming since my experience is limited).And since he always wanted to learn, but never found the motivation to do it alone, I think it's a good opportunity. ;) ---- I should receive the LQFP32 to DIP...

    About your post on the developer blog, you said that the cards are hard to plug in the slot. I had the same problem when I changed the cartridge connector for a brand new one in my NES, you probably just have to break in the slot ;) I'm still waiting the breakout boards for the STM chips I...

    Eagle free is okay for "small" 2 layer boards. If you want to make more complex boards with more layers and/or boards larger than 10*8cm, the only solutions are either using another tool to design your board or paying for eagle. That reminds me that I still have a few PCB to design : - AMS hall...

    Too bad about the borked eZ80, I hope you'll get some of those working. I can understand your disappointment, it's really annoying when you've done everything right and it still doesn't work. ----- I got my ST-link/V2, 40 pins ZIF sockets and my super cheap Super Famicom today, girlfriend was...

    http://www.ams.com/eng/Products/Position-Sensors/EasyPoint-Joystick-Position-SensorThere you can find the hall effect chip AS5013 and the joystick module N40P105 (with "pins" for better mechanical connection to the PCB, they call that combination "EasyPoint." The joystick feels a bit like the...
