This guy is a badass.

God damn right he is, that's freaking awesome! I wouldn't mind having a bash at making a console myself when I get the time.

anyone got a circuit diagram from woz's first computer when apple was 1 computer in a garage. i would love to make one of those

So campus safety decided to reprogram my door code while I was at work today.. got back and had to climb in through the window to get into my own room. I wired up a toggle switch to the override inside the back of the keypad and stuck it where it's not visible but just reachable under the door. Now I just push a button and my door opens regardless of what keycode is programmed into it.

I'd reset it to my own code again, but I'm leaving in a week and have no way of knowing the current code to fix it before I leave.

Sweet stuff. How the hell'd you guys learn to do cool stuff like this?

I took it apart out of curiosity. My roommate decided he was gonna unplug the battery for some reason, lol. When we plugged it back in our code didn't work anymore but 12345 did. So I googled the model number and found the manufacturer's owner's manual and hilarity ensued.

That would be freakin awesome.

I have a quick question about breadboards. I didnt wanna start a whole new topic so here it is. I am trying to do this arduino tutorial but I think the breadboard I have now will not work for it. Here is a picture of the tutorial I am trying to do:

And here is the breadboard I have:

As you can see the tutorial breadboard has two strips on each outer sides ( I think they're called bus strips ) while mine only has one. Should I go out and buy a new breadboard or can I somehow make this work?

Dude, you totally don't need to buy a new one. Even if you didn't have a single rail, you could still make it work.

They're commonly used for ground/VCC inputs. If you notice the diagram, the +5V and the GND pins are both going to the bottom rails. Then both of the bottom rails are being wired to the top two rails. It's completely redundant. They're only doing that, so that you can easily access the GND/VCC from either the top or bottom of the breadboard.

That's good to know, I'll get back to it. Appreciate the help falco

No prob. Welcome to the wonderful world of electronics... post if you need anything else. We don't have enough of this kind of shit going happening on these forums.

I've made some cool stuff with my Arduino. Made a tiny game on a 8x8 LED screen once. Had to tear that apart for another project >_<

Really wanna try making something with it again, sometime soon.

Thanks, I have a feeling I'm gonna be asking A LOT more questions. Electronics are fun, but hard too. If it'd be appropriate, you guys should definitely add a new section to the forums.

You should post pics if you had any. I'd love to see it. Also if anyone else has pics or wants to share what they've worked on, I'd love to hear about it.

I'll leave that up to Falco to decide, but for now Programming Discussion suits the topic well enough.

As much as I don't think breadboarding has anything to do with programming, we can't just open up an entire new forum category for all two of us who do this kind of stuff... I do hope that some day when we introduce more of this into our videos and feature more of it on the site, we'll have enough people interested to make a dedicated forum.

Alright that sounds fair enough.

I've been wanting to get into that stuff as well... you guys open up that forum and I'll get to buyin some supplies lol

wow, i didnt know you guys knew about arduino
i have a side project writing and interface for a home automation system. essentially equivalent to Z-Wave. (except we are selling to clients for half the price)

Started a new thread for arduino viewtopic.php?f=4&t=6265
