6502 Gate Simulator

Ever wondered what’s going on inside that chip as the program executes? Now you can take a look at the die itself with this visual gate simulator for the 6502 processor. [Thanks Puli and Svofski]

Copper corrosion

[Moogle] cracked open his DockStar to find corroded copper. It seems that Seagate left a portion of the ground plane unprotected and it reacted badly with the shielding metal. If you have one of these devices you might want to crack it open and tin the exposed copper so that it will hold up over time.

Segway kickstand

Don’t want your Segway to flop over when you park it? Follow [Paul's] lead in building a kickstand for the self-balancer. You can just make it out in the image above. It’s a dumbell that folds down from the handlebar tube when you’re not on board.

Tesla makes everything better

Do you like the song Iron Man? We think it’s better when our friend Nikola takes part.

No Smoking

Smoking is really quite bad for you. Plus you can’t chain smoke nearly as efficiently as this mechanical smoking machine can so don’t even try. [Thanks Ferdinand]

    #4: Damn. Are they wearing chain mail? Just imagine how the 100 Years War could’ve turned out if the French had Tesla generators…

    #5: Guess that’s an efficient and safe way of collecting butts for DIY ammo… http://mythbustersresults.com/episode84

    @uzerzero
    The “cain mail” is a Faraday cage.

    The smoking machine is a beautiful piece of mechanics.

    Anyone else just get “loading 6502…” for the 6502 Gate Simulator? (Firefox 3.6.10)

  4. svofski says:

    @hmm: the 6502 simulation uses debug features native to Chrome, or provided by Firebug extension in Firefox.

  5. biozz says:

    i would not call it a “Virtual” kickstand … more of a physical human emulator XD

    Smoking machine, wow, how can I learn to do something like that myself? I mean, to learn electronics, no problem, but mechanics? Gears? Brass?

  7. Patrick says:

    hey, that visual 6502 is awesome.

    Very nice, if you want to understand how a CPU works.

    I’m kind of surprised the segway doesn’t have the ability to stand on its own without an occupant. Still, this is kind of a battery-intensive and theft-vulnerable way of parking it.

    That Tesla coil video is awesome. But I love how there’s a big shop fan running in the background.

    simulator works in chrome

    great links this week!

    i wonder if it was out of tune because its hard to play in those suits or they need to tune up their tesla soundsystem. they should doit again with an MP3 bc you cant tell if they’re really playing the guitar anyway. Awesome nonetheless.

    I am impressed with the 6502 simulator. From reading the presentation, there are plans to gate level simluate the Apple II which would be GREAT (especially Wosniak’s revolutionary Disk II drive that made affordable disk based storage available for the home market)

  12. jeditalian says:

    damn that machine made me want a smoke

  13. chris says:

    6502 is amazing!

    I’d love to see a video of say a simple loop modifying and address with all the parts shown explaining what is going on…

  14. Tachikoma says:

    Apparently you can write your own code for that sim. Should give it crack.

    Also the Tesla guitar dude owns as well.

    Nice collection of links HAD :) Love the gate simulator! The smoking machine reminds me of our middle school science fair project. We used running water to create suction on the cigarette and a majority of the tar was collected in the tube behind the butt. That was our smoking machine lol.
    Next year we did a Pulsed Ionic Induction drive VERY similar to the “caterpillar” drives on big nuke boomers at the time ala Hunt for Red October. Hint: The drive works the on the same principle as combing your hair and attracting the faucet trickle with the static charge ;) Again, wonderful collection of links :) Keep it up HAD :)

  16. Chris says:

    I am severely impressed by the 6502 simulator. I just wish it could run at full speed while emulating programs and such.

  17. svofski says:

    Anyone who is seriously interested in simulating CPUs and seeing what is really going inside can try FPGA. This is not going to be gate-level simulation of the original CPU, but you will be able to see how individual signals and busses in your Verilog or VHDL model change as the CPU is crunching. To run simulations, you do not even need a development kit, but the real fun begins when you tap into a working design of course.

    The simulator runs fine on my firefox.

    As for the dockstar, I found that everything sold has some issue, it’s good to find what it is since if you can fix it yourself as in this case you are golden and you won’t find the flaw later.
    But seriously, it’s a rule, everything has at least one (sort of obvious) flaw, from spaceshuttle to flashdisk.
    That’s also handy since if you come across a review of something and they report all is perfect and don’t mention a nagging flaw then you know the reviewer is either not trying hard or he’s paid off (I’d say the last one is slightly more common than the first one)
