The Wii Golf Glove

April 27, 2010 by Mike Szczys 14 Comments

[Shu Uesugi] is filling a controller void that Nintendo has yet to address. He picked up a golf glove from Target and incorporated it into an air guitar interface. Give the video after the break a chance, you’ll start to see the full potential of this build about three and a half minutes into it. Using an Arduino, a Wii nun-chuck, and his flex-senor adorned glove [Shu] can play individual notes, strum cords, and play around with sound effects such as distortion.

So come on Nintendo, the Power Glove was one of your greatest ideas, where’s our 21st century version? I guess we’ll just have to make our own like [Shu] did. Perhaps we’ll even build our flex sensors from scratch.

Lawnmower Converted To Hoe/scraper

April 27, 2010 by Caleb Kraft 13 Comments

[Torx] wrote this instructable on how to convert a lawnmower to another useful tool. We’re not sure what language he natively speaks, but we doubt it is english, so you might be better off just looking at the pictures to figure out what he’s doing. To summarize, he has lowered the mower and reversed/bent the blade to scrape the ground. He has also added thick rubber edges all around to try to keep debris from coming out. You might be wondering why he would need something like this, but the last page sums it up pretty well. We could imagine this possibly getting some use in the garden as well. This one does look pretty dangerous though, so don’t blame us if you cut off a hand or lose an eye to some debris. Then again, a regular lawnmower looks pretty dangerous too.

IEE Clock

April 27, 2010 by Caleb Kraft 21 Comments

The IEE clock looks somewhat un remarkable at first glance. Upon closer inspection though, you’ll find out that there are 12 light bulbs crammed in there for each digit. The bulbs sit behind a curved lens with the numerals on it. When the appropriate one is lit, it projects the number on the front of the clock. While it isn’t new, it is certainly new to us. It is also interesting that you set the time by rotating the little dial on the top right. While it may be easier to set the time that way, it seems that it would be prone to getting nudged on accident.

Lawnmower+stake+rope=Analog Robotic Lawn Service

[Kirov], a regular reader and one of our most notorious commenters, tipped us off about this lawn mowing hack. On one hand we’re wary that this is bait for a huge flame war, but on the other hand it’s a hack that brings a smile to our mischievous faces. By pounding a stake into the center of the yard and connecting a mower to it with a piece of rope, [Korey99] has achieve an automated lawn mower. He tied the self-propelled mower’s throttle bar down to make the machine run unattended. There’s no kill switch or any kind of remote control for the lawn mower so we wonder what happens when the rope gets all wound up?

The MIDI piano instructor is a tool aimed at those who wish to learn to play piano, but don’t want to take lessons. The LED bar mounted above the keys lights up to show you exactly what key to press and when. We’ve seen this available in some electronic keyboards for some time, but this unit would be able to fit any standard sized keyboard. Check the page for schematics and pictures.

Printable Appendage With Two Joints And Integrated Motors

April 26, 2010 by Mike Szczys 15 Comments

[Kris Reed] developed this robotic appendage as a follow-up to his original prototype. He printed it using Alumide which is a printable material with aluminum dust mixed into it. [Kris’] design utilizes three gear types; large gear, small gear, and worm gear. The motors are mounted on the middle portion of the assembly and offer an elbow and shoulder type of setup that both rotate along the same plane. We’ve got video of the testing after the break. He makes note that the movement is a bit jerky but can be cleaned up with better motor control using PWM.

Altair 8800 Pc Case Can Emulate The Original Hardware

April 26, 2010 by Mike Szczys 9 Comments

The Altair computer is commonly considered the genesis of personal computing and for that reason it has a special place in the hearts of many. [Bob Alexander] brings back the glory of the Altair 8800 plus a lot of added computing power. This PC case houses a Core i5 system but the front panel isn’t just for looks. He designed a PCB and resized an image of the original Altair front panel to end up with a fully functioning control interface. In the demo after the break you’ll see that the buttons can be used for power and reset and the LEDs can show random Altair-like patterns. But the interface can also works in conjunction with an Altair emulator to perfectly mimic the original Altair experience. This is a great way to sidestep the buyer’s remorse one might experience with a standalone kit.
