Land ROV is Internet connected and packed full of stuff

April 29, 2012 By Leave a Comment

[Blair Kelly] has always been interesting in the concept of Remote Operated Vehicles. As soon as he got his hands on an Arduino he began his endeavor to turn an RC vehicle into a land-based ROV. What he’s done so far is incredible.

Here he’s showing off features of the build using a PS3 controller. But it can also take commands from an Xbox 360 controller or an arcade-style steering wheel. We like the latter the best, which is shown off at about six and a half minutes into the video (embedded after the break). Since there’s a webcam on board, this ends up being a virtual cockpit for the pint-sized car. But it gets better. That webcam is mounted on a servo motor, and [Blair] included controls that pan the camera. This lets the driver ‘look’ left and right. On the front of the vehicle there’s an accelerometer. Data is collected by the Arduino and sent via the WiFly module. This adds rumble to the controller if you’re using one that has that ability.

It’s a big project already, but it sounds like [Blair] has not end of ideas for future versions. Right now he’s planning to increase the overall size which will let him explore places that aren’t as flat as his livingroom.

Miniaturized N64 controller fits the tiniest of hands

April 22, 2012 By Leave a Comment

n64-controller-mod

The controllers that came with the Nintendo 64 don’t exactly measure up to the “Duke” of Xbox fame, but they’re not the smallest in the world either. Made by Bacteria forum member [Bungle] says that his girlfriend has incredibly tiny hands, so he thought he might try trimming some of the fat from an N64 controller by cramming its components into an N64 cartridge.

He tore down a 3rd-party N64 controller, tossing out the D-Pad, plug, and rumble motor, retaining all of the other buttons. After gutting the game cartridge, he heated the back side under a lamp and stretched the plastic over a roll of electrical tape to make room for the N64’s trademark “Z” button. Having only removed the rumble motor due to size constraints, he found a suitable replacement at Radio Shack, which fills in for the original nicely.

After a good amount of careful trimming, wiring, and mounting, he came up with the little gem you see above. We’re sure [Bungle’s] girlfriend is pleased with his work, and he seems happy with how it came out as well.

Continue reading to see a short video showing off [Bungle’s] latest creation.

[Thanks, Chris Downing]

Build an elevator controller, gain a friend for life

April 1, 2012 By Leave a Comment

diy-elevator-controller

[Michael Ruppe] was working one day when a man named [Kevin] approached him for a bit of help with a project. It just so happened that [Kevin] was in the middle of constructing a DIY residential elevator and he needed assistance putting a control board together.

[Kevin] had no problem casting a forklift ram into his basement slab, nor installing a submersible pump in a custom-made hydraulic pit, but wiring up the controls for the device was just not something he was comfortable with. [Michael] was more than happy to lend a hand, and over the next couple of months the pair got things running nicely.

Instead of relying on a microcontroller, [Michael] built a control board that uses little more than a handful of relays and microswitches to get the job done – It’s certainly not hard to appreciate the controller’s simplicity.

It’s stories like these that remind us just how much the hacker community is willing to help out complete strangers with any task, big or small – you guys rock!

Stick around to see a short demo video [Michael] shot, showing the elevator in action.

Sentry gun controller-board upgrade

March 29, 2012 By Leave a Comment

This open source sentry gun controller board builds on a great concept by getting rid of the Arduino board. The previous version was an Arduino shield, but this upgrade keeps all of the cool features by rolling the necessary parts into one smaller footprint.

The image above doesn’t quite convey the scope of the project. Go take a look at the feature from last year which used the shield version of the controller. That build used a servo-mounted paintball gun in conjunction with a webcam. You can still build the same platform, but use the open-source files to include this board. It has outputs for three servo motors, and can also interface with airsoft or paintball guns which have their own electronic triggers and integrated batteries.

We always like to see the schematic for projects like this one. For your convenience we exported an image from the Eagle package. You can find it, along with the demo video, after the break.

Trumpet Hero

March 29, 2012 By Leave a Comment

[Evilsigntist] combined an old cornet with an old PS2 guitar hero controller to produce the Trumpet Hero. The fragile looking conglomeration really brings a smile to our faces. Just make sure the instrument has already seen the end of its days before drilling holes to mount the various parts.

In the image above you can see that the three valve buttons have been painted to correspond to frets on the original guitar controller. The orange and blue frets are positioned for the left hand to operate. There seems to be a couple of different version because there is a diagram showing a mute in the bell that can be twisted for whammy bar input, but that’s not shown here. Strumming is accomplished by blowing through the mouthpiece, but as you can see in the video after the break, no buzzing is necessary.

Using actual instruments as game inputs is a lot of fun. We always think back to the flute and drum set controllers for Rock Band.

Hot dirt keeps your plants happy in the winter months

March 19, 2012 By Leave a Comment

[Craig] tried heating his greenhouse last winter, but really only managed to push the limits of his utility bills. This time around he took a different approach by building a system to warm the soil in which his vegetation is planted.

The core of the system is this box which houses the plants. It is lined with heating tape along the bottom which warms a layer of dirt. The plants are in pots, but since those are surrounded by the dirt it doesn’t really inhibit the warming properties of the soil. The controller takes into account the temperature inside the box, as well as ambient temperature in the greenhouse. When it’s a bit too cold the controller will close the lid, which is covered with translucent plastic. This makes sure the temperature around the plants won’t fall below about 41.5 degrees Fahrenheit.

This really takes the work out of caring for you plants in the winter. What would have been a multiple-times-per-day visit can be limited to every day or two. Now he just needs to expand this to regulate temperature and humidity in the greenhouse itself, kind of like this other hack.
