Mind Control Via Serial Port

brain-control-via-serial-port

[Zibri] found a very simple method for using brain waves as a controller via a DB9 serial port. He’s using Uncle Milton’s Force Trainer which we saw yesterday in the brain controlled Arduino. In that project the Arduino tapped into the LEDs and interfaced those signals with a computer via USB. This time the connection was made using an RS-232 transceiver to pass data from the programming header inside of the toy’s base unit to a computer over the serial port. Tapping into the programming header has a lot more potential and should be more reliable than sniffing logic out of LED connections. [Zibri] has written an application to display the received data but it doesn’t look like he’s made the code available for download.

Apparently he tipped us off about a week ago. We recall seeing this submission but as you can tell it’s a little bit light on the detail. So if you want your tips to be at the front of the line, make sure you do what you can to fill us in on all the details of your project. At our request [Zibri] provided a picture of the PCB from the Force Trainer’s base unit. See it after the break. Continue reading “Mind Control Via Serial Port” →

Ski Bot

[Bojan Nemec] has come up with a robot that can ski better than us.  Not that skiing better than us is a hugely lofty goal. The bot is capable of skiing using standard, off the shelf skis. It has a dual computing system. One system only does steering and balance while the other does all the vision and control. He’s using the carving technique of skiing, stating that normal skiing is just too hard for a robot. That sounds like a challenge to us. You can check out the blooper reel, which is still better than us, after the break.

Yahoo Hires Strippers For Hackers

Yahoo has issued a public apology for an event that occurred at their recent Hack Day in Taiwan. Apparently they  hired strippers for the event, two years in a row. The girls did their usual bump and grind all over some poor hackers. Poor guys. While there is a part of us that says, “what about the little girls getting into hacking?” the other part of us says, well, you know what it says.  Wow, we’re suddenly feeling the urge to use yahoo for all of our services. How peculiar.

Industrial Robots Producing Art

Here is an interesting project that should spark some good discussion. Artaic is a company that is using industrial robots to produce mosaics. They are then selling these mosaics as fine art. As you can see, some of the examples are quite nice looking. However, we have to wonder what the draw is to own one that is made by a robot. Is it really that much different from just printing an image? We really do think it is a cool project and an efficient way of producing these mosaics. We would really love to see one of those super fast delta robots doing the work.

We’re trying to reduce the negativity here at Hackaday. We are passionate geeks and hackers, and as such, we tend to jump straight to the negative points. We hope you guys will follow along with us and try to be constructive in the comments. That being said, the video did seem a bit pretentious, didn’t it?

Bouncy IPhone Controlled Dance Lights

[John Boiles] introduces us to dimlet, his portable network controlled light dimmer. Inside the box is a fonera 2100 router that is running openWRT connected to an unnamed AVR microcontroller. Right now, he’s controlling the unit with his iPhone. It has three modes of control; a manual “slider” mode, an accelerometer controlled “dance” mode, and a programmable “tap” mode. You can download all the source code and schematics on his site.

Ps3 Laptop Courtesy Of Ben Heck

[Ben Heck] may be the coolest person ever (take that [Adam Savage]). You would think that after producing so many laptop versions of gaming consoles he would grow tired or we would be bored of them. But no! We love each and every new production – including his latest laptop-ified Ps3. Not too much in the terms of ‘new’ comes from his latest article, but it does reaffirm some things including: why make what you can buy, cheap foam sheet should be purchased by the ton, and use the screws from an overheated Xbox 360 when you lose the Ps3 originals. Oh, and [Adam] we were just kidding, you know we will always love you. Check out a video after the break.

Well Engineered Diy Segway

[Mark] wanted a Segway but why buy something if you can have more fun building it? His end product is an amazing homemade version of the self-balancing transportation package. We’ve seen several projects that include auto-balance, but this one is large enough to ride on and has a bit of an advantage in the design. The motors, batteries, and other components are mounted below the wheel hubs and are weight balanced. This means that the device wants to find balance naturally, even when the electronics are switched off.

The frame was modeled in CAD and then welded together. For propulsion [Mark] has installed two 750 Watt motors which will use sprockets and chains to turn the wheels. The machine balances based on data from both a gyroscope and an accelerometer, with the entire packaged tied together using an Arduino.

[Mark’s] build log is well laid out and details each part of the build with a different post. His two most recent entries include video of the unit balancing and of him riding the 95% completed project. A big thanks to [Mark] for taking the time to document this so that we can share in the excitement of a well-executed project.
