I would like to see this crazy robot play a match of table tennis with a human. Prepare to be amazed, these videos are unbelievable!

"Interactions in the real world (not only physical but also social and psychological interactions) are inherently parallel phenomena. By constructing models and engineering systems that take into account such parallelism, one can expect a better understanding of the real world as well as enhanced performance of systems when dealing with practical applications. These fundamental considerations lead us to concentrate on parallel processing for sensory information. Four main related topics are currently being explored in Ishikawa-Komuro Laboratory:

  1. Sensor Fusion theory and implementation in engineering systems;
  2. Dynamic Image Control Dynamic control of image based on high-speed visual information processing;
  3. Massively parallel image processing through a Vision Chip, which is capable of realizing high-speed real-time vision tasks on the basis of VLSI technology, and
  4. Meta Perception concerns ways of capturing, manipulating and presenting information which is normally inaccessible to humans and machines.
  5. (Past research on Optics in Computing: architectures that combine the advantages of optics and electronics to realize enormous computing throughput)."

Display Text on Oscilloscope using PIC16F628A

at 2:24 pm. Filed under DIY Hacks, Electronic Hacks


This Oscilloscope Display project uses no external components! All you need is the microcontroller and a power source. Source code is provided so you can build your own.

Metal Finding Robot

at 4:45 pm. Filed under Electronic Hacks


This Metal Finding Robot is a work in progress. The creator hopes that it will find enough money to self fund its completion. That is a goal that I am sure most robot creators could only dream of. I could see letting a few of these loose in a park the day after a big event and collecting tons of cash!

"The Metal Detector consists of 2 separate detetor coils wound around a ferrite rod. The Circuit is a Beat Frequency Oscillator – able to detect metal and also live electrical cable. The Beat-frequency oscillator (BFO) is the simplest type of metal detector. The basic beat-frequency metal detector employs two radio frequency oscillators which are tuned near the same frequency. The first is called the search oscillator and the other is called the reference oscillator. The outputs of the two oscillators are fed into a mixer which produces a signal that contains the sum and difference frequency components. This signal is feed to a low-pass filter removing the harmonics. As long as the two oscillators are tuned to the same frequency, the output will have no signal. When a metallic object disturbs the magnetic field of the search coil, the frequency of the search oscillator shifts slightly and the detector will produce a signal in the audio frequency range. "

64 RGB-LED Panel with Multi-Touch

at 12:27 pm. Filed under Complex Hacks, Electronic Hacks


Edo has just added multi-touch capability to his 64 RGB-LED Panel with Multi-Touch. This is an enhancement to the initial design which later got video capability. Keep up the great work Edo! Hopefully Edo will pass along some details and pictures of his work.

Let Arduino Play – Brico Geek Project

at 9:36 am. Filed under Contests, Electronic Hacks, Game Hacks


Our friends over at Brico Geek are having a cool Arduino based contest called Let Arduino Play. All you need to do is make a cool game using an Arduino and enter. There are lots of cool prizes to be won so it’s sure to be a fun contest. I am one of the judges and am looking forward to seeing all of the entries! Note that the main language of the site is not English so please excuse some of the mistakes, they will get cleaned up.

"All you need to do is make a game with an Arduino board. You can use any version of the board available but it must be playable so user can interact with your project. For example you can make a Simple Simon game or even a world domination multiplayer game with graphic LCD with sounds, why not! Just let your imagination flow and do it. The jury will be looking at the presentation, originality, documentation and execution of your project. Don’t forgot to grab a video demonstration!! You can submit your project, one per person, before the deadline show on the right of this page, so be quick! Once the contest is over, our jury will inspect all the projects submitted and select the three winners."

MIDI Shoe Hack

at 1:12 pm. Filed under DIY Hacks, Electronic Hacks, Funny Hacks


This shoe hack allows you to play MIDI with you shoes! No more boring walking around, now you can play a tune where every you go. 🙂

"I’ve put together a pair of shoes that, with a little help from an Arduino, will let me trigger MIDI signals. There are FSRs (Force Sensitive Resistors) in the heels and toes of the shoes, which serve as the tap sensors. Basically, an FSR, without any applied pressure, is like a break in a circuit (i.e. has infinite resistance), and as you apply more force, it becomes less and less resistive. So, if we hook up one end of an FSR to a voltage source and the other to the Arduino’s analog input, we can send a signal to the Arduino every time we apply pressure to the FSR. We can then take this signal, convert it into MIDI, and start making sounds. I used the Serial-MIDI Converter from Spikenzie Labs. The serial-MIDI conversion could likely be performed in MAX or otherwise manually, but this does the trick and saved me some time. For the actual sounds I used Garageband, but you could use MAX, Ableton Live, etc."

Make your own Magic Mirror using Arduino Microcontroller

at 8:45 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks, Funny Hacks


This Magic Mirror is an interesting way to get caught up on what is happening today. It will tell you how your stocks are doing, the local weather and more. It is also sure to be the most elaborate door bell that will be a conversation piece to all who see it. The software and electronics needed are sold as a kit. See the install steps here.

"Take that extra PC you have lying around and turn it into an Interactive Magic Mirror. You build the hardware using an Arduino and some sensors following the instructions on http://diymagicmirror.com and then install the DIY Magic Mirror Software which runs on the PC, Mac, and Linux.

Magic Mirror Features:

  • Weather Forecast
  • Stock Performance
  • X-10 Lighting Control
  • Picasa based slideshow
  • Princess, Pirate, and Halloween Modes
  • Personalize it with your own Videos
  • Runs as a native application on the PC, Mac, and Linux"
