Bongo Pong
2007-07-09 13:01:32
Imagitronics has created a new interactive version of Pong. He calls it Bongo Pong, rolling right and left on a platform controls your on-screen pong paddle. Video after the jump. “I started work right away on the project. I quickly found out that Indo boards do not come cheap, with prices starting around $80, so I decided to make my own. For $6 I was able to get a short length of 5″ PVC pipe and a piece of wood (which I later replaced with the skateboard deck seen in the video below), and some small metal tubes to use for the tilt activated switches. The total expenditure was less than $20 for enough equipment to make a board for each player.” ...
 
Automated Weed Pulling Robot
2007-07-08 13:00:54
Will the farmer be a thing of the past soon? The HortiBot is an interesting idea that could automate many tasks. With larger automation everything from planting to harvesting of crops will be able to be automated. Video after the jump. ” The vision is the Spider mounted with the HortiBot accessory kit, which transforms it into a tool carrier for high-tech plant nursing for e.g. organic grown vegetables. High-tech tools for weeding that at a later stage can be implemented are tools like laser, micro spraying and mechanical devices. The HortiBot is capable of passing over several parcels with visible rows auto­nomously based on a commercial row detection system from Eco-Dan with no use of Global Positioning Systems (GPS) which is normally used by UGV’s. Unskilled workers will be able to operate the basic functions of the HortiBot within one hour of education and by use of a pictogram based operational guide. Report of operational analysis documenting the HortiBot conce...
 
Inside the iPhone CPU
2007-07-07 14:53:21
Our friend Nick Chernyy from uBlog has got his hands on an Apple iPhone and worked his magic to get a shot of the CPU wafer image. “The chip contains both the ARM CPU and the RAM, three dies to be exact. The CPU had what looked to be a model number and the RAM chips had what looked to be part of a model number on the cut-away part of the die. No visible logos or slogans on these chips.” ...

Light LEDs in a Hot Dog
2007-07-06 13:03:14
Have you ever seen LEDs powered through a hot dog before? Well Evil Mad Scientist Laboratories has been having some fun running some juice through a hot dog and lighting LEDs that were simply stuck into the hot dog. “If you’re *not* going to eat the hot dog, a neat trick is to stick a bunch of standard LEDs into it. (Yes, this really works!) Apparently the voltage between nearby points on the hot dog is fairly low, since the LEDs don’t seem to burn out. As the hot dog cooks, the resistance of the hot dog increases and the LEDs get dimmer since less current can flow through them. If you look *very* closely (or take a time lapse movie) you can see the LEDs move further apart as the hot dog swells during cooking.” ...
 
Exploding a Potato with Defibrillator Capacitor
2007-07-05 13:14:42
  This video of a Potato Exploding with the discharge of a Defibrillator Capacitor is very impressive. The 54uF/4200V capacitor was charged up to 3000VDC prior to the discharge. If I ever have a heart attack I think I might just tough it out and hope for the best. ...
 
Holographic Video
2007-07-04 13:02:42
Could the technology that MIT’s Michael Bove is working on change computer displays as we know them today? It wasn’t long ago that LCD flat screens took the market over. Are we going to see a similar change when Holographic Video technology matures? “The Media Lab’s video holograms appear to float above a piece of frosted glass. An electronic device behind the glass, called a light modu­lator, reproduces interference patterns that encode information about the pictured object. Laser light striking the modulator scatters just as it would if it were reflecting off the object at different angles. A holographic video begins with a computed 3-D model of some moving object or scene. This model “can be thought of as having a whole lot of points on its surface at different depths that change over time,” Bove says. To make that model holographic, a computer needs to figure out the intensity of the light that would be reflected from each point on the objec...
 
DIY Laser Engraver / Cutter
2007-07-03 13:23:14
If you ever wanted to do some laser engraving, this project might be of some interest to you. The circuit is basically a variable voltage regulator that is powering a high power laser. I would highly recommend laser goggles when experimenting with devices like this. “This laser will immediately BURN AND CUT anything you put in front of it faster than a hot knife through soft butter. And, a laser is a light beam, so it will REFLECT OFF OF ANYTHING SHINY OR REFLECTIVE AND THEN BURN WHATEVER ELSE IS NOW IN ITS WAY. You’re not going to cut shiny foil or anything else that reflects light unless you want a quick trip to the Emergency Room. Treat this with the respect you would give any powerful tool. Put something under your work that won’t burn, or you don’t care about. A sheet of plywood is disposable, but cheap sheetrock drywall is meant to hold flames down (the white side, not the paper side). Have somebody at Home Depot show you how to easily score drywall an...
 
LEGO NXT Rubik’s cube solver
2007-07-02 14:24:10
Daniele Benedettelli made a LEGO robot that can solve the Rubik’s Cube automatically. Looks like the robot has been well thought of and constructed. Video after the jump. “A motor actuates a prismatic joint that pushes the side of the cube; another rotates the cube’s support; the third one has the double function to help the pusher arm to accomodate the cube on the support and to hold the cube while the bottom face is rotated. The robot uses 2 touch sensors as limit switches for the arms and a light sensor to zero the rotating base.”   ...
 
iPhone Taken Apart
2007-07-02 13:52:34
Hacked Gadgets doesn’t normally cover off the shelf items but there has been so much buzz over the iPhone and the guts do look interesting. One of our advertisers, iFixit, bought a perfectly good iPhone and took it apart to see what makes it tick. By the looks of it Apple doesn’t think the battery will ever need replacing… Great job guys! “Samsung manufactured Apple ARM chip. Numbers: 339S0030ARM, 8900B 0719, NOD4BZ02, K4X1G153PC-XGC3, ECC457Q3 716. The processor is likely stacked on the SDRAM, which looks to be 512 MB. This chip could have H.264 and MP3 hardware decoding built in. The chip above the ARM is a Wolfson audio chip. Part numbers WM8758BG and 73AFMN5. The chip underneath the ARM is a Linear Technology 4066 USB Power Li-Ion Battery Charger, which Apple uses in the iPods as well.” Via: Make ...
 
Jet Powered Sinclair C5
2007-07-01 13:40:59
The Sinclair C5 doesn’t look like a vehicle that would turn many heads. Dropping a Jet Engine into the Sinclair sure changes that! Video after the jump. “I purchased the C5 from a nice chap called Ron, the entire chassis is going to be replaced and the power source will be a gas turbine. I’m going to drop the Turboshaft Kart and use the engine as a Turbo Jet conversion on the ‘Jet Powered Sinclair C5′. The engine is an Air Research JFS100-13A; its happens to be the same make and model of engine that is being used on the Jet Go-Kart.” Via: Retro Thing   ...

Diode based Fan Controller
2007-06-29 13:51:30
Diodes can be used for temperature sensing. Nick Chernyy used this principle to make a Diode based Fan Controller for his Shuttle PC. “Figuring that I should just go build a more substantial fan controller myself, I promptly went to the lab to look for a thermistor. Unable to find one, I settled for the next best thing: a diode. After building the circuit, I tested the output with a DMM and applied various amounts of heat using a hot air gun. For the final install, I simply stuck the diode inside the CPUs heatsink/heatpipe assembly, connected the device to power and the output to the fan.” ...
 
Text-Based YouTube Video Player for Linux
2007-06-28 22:37:00
  Working on a command line Linux system and want to watch a YouTube video? Until now you were out of luck. Warren Harding has designed a program that reads in a YouTube video and plays it using ASCII text! “This is a concept video depicting how users can surf and even watch videos from youtube with out the use of a Graphical User Interface. The operating System is linux fedora 6, I used the lynx text based browser to search for a video on youtube, then I dug through the source found the keys required to build a request to download the desired video. Once downloaded I invoked the shell from lynx to launch mplayer to play the downloaded video. Mplayer is a really handy media player utility, if it doesn’t see X it uses a text engine to render the video, it has support for every codec you could think of including flv.” ...

Binary Marble Adding Machine
2007-06-28 13:34:55
Learning binary addition would have been more interesting if it were demonstrated using a Binary Marble Adding Machine. Video after the jump. “The core of the invention is a modification of the divide by two flipflop to retain the marble that falls off the right side, and keep it until the flipflop is flipped to the left by the next marble. See small diagram above right. The retention of this extra marble allows the state of the marble accumulator to be dumped. The adder would just as well add without it, but the number would have to be read off by the angle of the rockers, rather than have the device dump the count out. Really, if such an adder were integrated into a hypothetical marble computer, reading out the result as a series of marbles would be an essential element.” Via: TechEBlog and Make   ...
 
USB Controlled Traffic Light Status Indicator
2007-06-27 13:00:54
Imagitronics from Japan shared his latest creation with us in the Hacked Gadgets forum. It’s a USB Controlled Traffic Light Status Indicator which he built to show the number of running applications at a glance. “I retrofitted this generic “Blinking Traffic Light” with a USB module and wrote a simple Mac application to monitor my computer usage and reflect the results in by changing the stoplight. This project was born out of the frustration after being constantly interrupted by people who could not tell that I was already busy. The alpha version of the software detects the number of running applications on the computer using Cocoa’s NSDistributedNotificationCenter and updates the light based on a user-defined threshold.” USB Controlled Traffic Light Status Indicator ...

Computer Controlled Room Ambilight Controller
2007-06-24 19:15:58
Check out this Computer Controlled Room Ambilight Controller that Mike built. I didn’t realize that there was an open source program that would perform the same screen analysis as the Phillips Ambilight system, this gives me some ideas… Video after the jump. “What it basically does is, it waits for info from the PC through the RS232 interface and then controlls the brightness of the different collors. I then wrote a programm which sends bytes to the cotroller depending on where the mouse is positioned on the color triangle. The second program is a opensource program called BobLight (http://www.xs4all.nl/~loosen/elektron… ). it looks at the screen and then sends the dominant colors through the comport. I modified it a little so it would only look at the top left corner of the screen. the I made a plugin for winamp that produces plain colors depending on the beat of the music. That’s about it. then I made some LEDclusters and strips and mounted them i...
 
TTL to RS232 adaptor Explained
2007-06-23 21:25:56
When building microcontroller projects it’s often desirable to connect them to a computer. Most RS232 computer ports are able to read 0 and 5 volt TTL data levels however there are some computers that require voltage levels that are closer to the true RS232 spec. Most people use a MAX 232 chip when there is a need to follow the spec. correctly, but it’s possible to build your own circuit. uC Hobby has an article that shows and describes a circuit that does just that. “The basic problem we have to solve is that the uC UART is a logic level device and RS232 is not. To send data over RS232 the voltages need to be about +/-10V while the output at the uC will be 0-5V or 0-3.3V. To see a zero signal the receiving RS232 device needs to see a negative voltage. We also need to invert the phase of our logic signal so that a 1 (5V) is converted to the negative voltage (-10). Typically the threshold for 1 vs. 0 in the RS232 receiver is slightly above 0V we can get away with u...

Induction Heating Demonstration
2007-06-22 13:44:11
Richie Burnett has a Induction Heating Demonstration that is worth having a look at. Richie has also done extensive work with Tesla coils, make sure you have a look at those also. “Induction heating is a non-contact heating process. It uses high frequency electricity to heat materials that are electrically conductive. Since it is non-contact, the heating process does not contaminate the material being heated. It is also very efficient since the heat is actually generated inside the workpiece. This can be contrasted with other heating methods where heat is generated in a flame or heating element, which is then applied to the workpiece. For these reasons Induction Heating lends itself to some unique applications in industry. How does Induction Heating work ? A source of high frequency electricity is used to drive a large alternating current through a coil. This coil is known as the work coil. See the picture opposite. The passage of current through this coil generates a very i...
 
Home Made CNC Machine
2007-06-21 13:18:13
Our Danish friends David Pedersen and the guys from AC/KW got together and built a CNC machine from scratch. There are lots of videos and pictures of the build on the site. Have a look at the 3D Hacked Gadgets logo, this machine does a great job! “The CNC mill has been built from scratch. We’ve even made our own controller board to drive the stepper motors that power the axis of the CNC mill. What makes the CNC mill tick? It’s the controller board. I don’t want to go into details on how the CNC controller board has been designed. This is just a quick overview of the project, and a more detailed description of each subsystem will be written some day. The board is based around a central PIC controller, the PIC18f2220. An optocoupler bridge isolate the parallel port cable from a PC from the rest of the board. You cannot see this bridge on the picture below as it is SMD mounted on the back site of the board. 3 arrays of FET transistors are used to provide motor...

Orange worked with the University of Texas to develop a charger that would take advantage of the English climate ‘to ensure a constant energy source.” Via: Cooler ...
 
Graduation Cap LED Hack
2007-06-20 13:48:58
Long time Hacked Gadgets reader Chris Rybitski sent in this cool Graduation Cap LED Hack. It uses a blue LED to add some electronic goodness to a plain old Grad Cap. By the way, congratulations on graduating Chris! “I used three button cells from a light up bouncy ball to power the high intensity blue LED. Then I hot glued the batteries to the inside of the cap. To turn on the LED I just put my hand up to the side of my cap and push. Originally I wanted the switch to be in my gown sleeve, but I had no way of hiding the wire going from the cap to the gown. If I had long hair I could have pulled it off. The LED is hardly noticeable until I press the button.” ...
 
Vintage Wi-Fi Radio
2007-06-19 14:13:45
If you like cutting edge gadgets then you need to get your hands on a Wi-Fi radio, but what if you have a love for antiques? Alinke used a vintage radio housing and modified a Wi-Fi Radio to fit inside. At first glance it looks like an antique, well until you spot the LCD display anyway. “I found a local vintage radio dealer in town. He’s a real purist and is only interested in preserving radios with the original electronics so he really didn’t have any interest in helping me out. It took awhile, but he sold me this box for $30. After a few Google searches, I came across this product which seemed a good fit. Its not cheap though and goes for $300. I shopped around a little and was able to get one for $260. The other one out there is this one and is slightly cheaper but I needed to be able to attach a knob to the volume control for the retro look as opposed to an iPod like volume control.” ...

Atmel Atmega based Electromagnetic Floater
2007-06-15 13:28:26
We have all seen these floating globes in the novelty stores and online. How would you like to build one? J. Hodgie has put together an article that will walk you through the required steps to make your own. The code for the Atmel ATMega168 Microcontroller is also provided. “It is much like the floating globes you can buy, except it works by balancing the forces of permanent magnets with electromagnets, rather then simply using combinations of permanent magnets. This is done by using a microcontroller and an IR sensor to detect where an object is floating below. Then based on a set value, the microcontroller uses the electromagnets to to hold the floating object at a given height. The place the object floats at depends on the weight of the object and the power of the magnets in the object. The height is set by holding the object under the magnets and sensor and pushing the button. The object floats at the point where the force of gravity down equals the force of the magnets p...

Handy Recovery 3.0 Review
2007-06-14 03:52:58
We have all experienced file loss at one time or another. For me it’s usually an accidental deletion of a directory when I am cleaning up old files from my hard drive. Soft Logica has requested Hacked Gadgets to perform an unbiased paid review of their software package called Handy Recovery. If you are working in a Windows environment chances are you could use Handy Recovery to restore some of your data in the future. The software downloaded in a few seconds since it is less than 1MB in size. Anyone that does Windows software development knows that an executable of this size is quite impressive. Installing the program was simple, all it took was a few clicks and about 30 seconds. There is extensive help available however I’m not fond of reading documentation, I would rather click around and just kick the tires. Luckily the interface is intuitive using a few large buttons along the top. One area that could be improved is the hover over tips and the help text at the bot...
