Recording Emotions with the Emotiv Headset

at 5:17 pm. Filed under Complex Hacks, Computer Hacks, Crazy Hacks, Electronic Hacks

Robert Oschler sent in this interesting project which allows Recording Emotions with the Emotiv EEG Headset to sense your mood. Just like the read receipt tells you if and when your email was read this would let you know what type of emotion it conjured.

“EmoRate is an application that demonstrates the power of Affective Computing, a technology that allows computers to detect and react to human emotions and will change drastically the way we interact with them in our daily lives. The last barrier that has held Affective Computing back, an affordable consumer grade EEG headset, has been broken with the introduction of the 14-electrode EPOC headset, created by Emotiv systems, Inc.”

Levitating Rotating Globe

at 9:13 pm. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks


Have a look at this Levitating Rotating Globe that Alexey Sha built. Not content with the standard levitating products out there he decided to step it up a notch.

“There are many globes available today which are levitating and rotating along vertical axis. This one is the world first globe levitating and rotating along TILTED axis. It uses wireless power transmittance and geared motor inside the floating globe. In brief, frequency generator is built around micro controller, a square wave output is directed to MOSFET which drives primary coil (10 turns) of output circuit. Secondary coil forms parallel LC circuit (20 turns and 25 nF) and serves as transmitting antenna. Generator frequency can be manually tuned around resonant value to control speed of rotation.

Receiver coil is a parallel LC circuit (~2.5 nF and ~60 turns of wire). It is connected to rectifier bridge. DC geared motor (made of micro servo, modified for continuous rotation) is powered by inductive resonant coupling. Receiving coil, electrical components, and tilted motor are fixed on the floating base. Their locations are adjusted to maintain center of gravity. The globe’s outer shell is directly attached to the motor shaft.”

Illuminatrix – Burning Man LED Project

at 5:54 pm. Filed under Cool Gadgets, Electronic Hacks

If you are heading down to Burning Man this year make sure you wander over to the More Carrot theme camp at 5:30 and Baghdad to have a look at this Illuminatrix which is a one metre square LED matrix.

“The system is contructed of 16 custom built PCBs, each containing a PIC16F1827 microcontroller which receives data via I2C from a master board and controls 3 MAX6964 LED Drivers via I2C – one each for red, green and blue components. Each board then runs two ribbon cables of 8 RGB LEDs.

The master board is running on a PIC18F26J50, a very powerful little PIC with an awful lot of I/O capability. Its reading the animations from an SD Card formatted with FAT32 using an SPI interface, it then chunks this data up, and sends it via the main I2C bus to the slave boards.”

at 4:30 pm. Filed under Contests


The prize this week is a mountaineering clasp that is sure to add some flair to your keychain or provide a cool way to clip your backpack in place. This contest will run for one week (August 28 – September 3, 2010) . Ending time is based on central standard time. To enter, identify the item pictured above and give an example of what can be done with it. You don’t need to know the make and model just what it is in general, and what this type of thing is normally used for.

Please do not give the answer in the comments.

Send an email to contest @ hackedgadgets.com with “Name the Thing Contest” as the subject, and the message body consisting of:

  • The name of the item in the above picture

PIC AXE Microcontroller based High Speed Photography Trigger

at 3:11 pm. Filed under DIY Hacks, Electronic Hacks


“I hacked a cheap camera flash shoe so that it has a 3.5mm cable jack insted of a pc-sync cable. A 10 cm ling Pc sync cable is 10 times the price of a 150 cm 3,5mm cable. I have a Brain circuit, a Sound Detecting Circuit and a sensitive gate SCR to trigger the flash. The picaxe is not overclocked (running at 8MHz). The box has a 3.5mm jack for a picaxe USB download cable so it is easy to program more. The code is now about 400 rows (basic) with alot of white space. alot of code is taken up by the menu system. I will try to make some kind of strobe funktion to”

Vacuum Cleaner Subwoofer

at 7:05 pm. Filed under DIY Hacks, Electronic Hacks


All speaker systems need a housing of some sort. Normally we see boring wood boxes with some holes cut in them so that round speakers could be mounted into them. There are a few companies who make some speakers which are not just boxes with holes such as the Bazooka Tube Subwoofers. Instructable user djairjr had an old vacuum cleaner which had reached the end of its life. After cleaning out some of the guts he was able to fit a woofer into it, now he has a very unique DIY Vacuum Cleaner Subwoofer.

Launchpad MSP 430 Programming with Linux

at 7:04 pm. Filed under Complex Hacks, Computer Hacks, DIY Hacks, Electronic Hacks


Mike Szczys from Hack a Day shows us how to Programming Launchpad MSP 430 with Linux. The basic method that people use to program their Launchpad MSP 430 is a Windows box but for those on Linux there is still hope.

“We’ll be working with Ubuntu 10.04 Lucid Lynx. When the Launchpad is connected to USB it is identified and mounted to /dev/ttyACM0. It’s not immediately apparent how to use the device but fortunately it can be done. To talk to the hardware for programming and debugging we’ll need to use MSPDebugger. For compiling our code we’ll be using the MSPGCC open source compiler package.”
