Monkey controls a Robot with Brain Power

at 5:45 am. Filed under Complex Hacks, Computer Hacks, What Were They Thinking

 

If this research wasn’t being performed by a reputable University I wouldn’t have believed that a Monkey could control a Robot with Brain Power!

"In a first-of-its-kind experiment, the brain activity of a monkey has been used to control the real-time walking patterns of a robot halfway around the world, according to researchers at Duke University Medical Center.

The Duke team is working with the Computational Brain Project of the Japan Science and Technology Agency (JST) on technology they hope will one day help those with paralysis regain the ability to walk."

Universal Remote Control Tester – Ubicom SX28 Microcontroller based

at 5:26 am. Filed under Complex Hacks, Computer Hacks, Electronic Hacks

If you have ever wanted to make a remote control project, this Universal Remote Control Tester project that uses the Ubicom SX28 Microcontroller could be a good starting point. This chip is now being sold by Parallax.

"This project use the Ubicom SX28 micro controller to made a test of the frequency and the complete wave taken form a IR remote control, could be an TV, Audio, VCR, or any type infrared. It consist of two parts, one is the hardware or the physical tester and the another one is the software.

The output state of the IR sensor will change from one to zero in a TTL level, the circuit will detect only this in the rb.4 SX pin , ( after a power on or reset ) starting at this point the RTCC register in zero, and while the rb.4 pin no change RTCC will increment by one each 16 times clock ( see option register configuration ) therefore 3.2 uSeg for a 50 Mhz clock, ok, while this happened the "veces" variable will increment by one many times as the RTCC produce an interrupt."

IR LEDs used to defeat Security Cameras

at 5:46 am. Filed under DIY Hacks, Electronic Hacks, Funny Hacks

I have seen lasers used to "dazzle" security cameras before but they normally use visible light and need pinpoint accuracy to be effective. I had never thought about using an array of IR LEDs (infrared light emitting diodes) to create a permanent result that would not be noticeable to anyone else around.

Original Version, Translated version

"IR.ASC is an infrared light – to the device before Divining infrared surveillance cameras.  There is no special technical knowledge of each reconstructed.  The device emits infrared light from the infrared images from surveillance cameras disturbs. The face of the person is monitored by a light ball over. Since the whole interaction in a non-visible spectrum (at frequencies between 780nm and 1mm), the man noticed nothing of it and he sees neither the infrared emission of radiation surveillance camera nor by the IR.ASC "

Almost There – Near Space Project

at 5:26 am. Filed under Complex Hacks, Computer Hacks, Electronic Hacks

 

A Hacked Gadgets reader took his Almost There project up to over 42,000 feet a few years ago and documented the process.  Looks like Near Space is gaining some popularity recently.

Here is a list of projects that are worth a look:

Near Space Project 1
Near Space Project 2
Near Space Project 3
Near Space Project 4

 

"So, here’s what I decided to do. Use a Pressure Sensor and a Temperature Sensor fed in to a PicAxe CPU that approximately once a minute will trigger the transmitter and bang out the raw data using simple Morse Code.

On the receiving end, I’ll use a matching FRS radio to receive the data, feed it in to the Sound Card of a Laptop, and a Cassette Recorder with sound level activation to record the data for time immemorial. Run software on the Laptop that decodes the Morse Code and displays it on the screen, and saves it to a Data file. Then (finally) I’ll have a conversion chart that I can look up the raw data values from the screen and manually convert them to Altitude and Temperature readings."

Canadian Inventor to Launch Bottle Rocket into Orbit?

at 5:21 am. Filed under Complex Hacks, Cool Gadgets, Crazy Hacks, Insane Equipment, What Were They Thinking

 

This Canadian inventor from Antigravity Research who holds the world record in bottle rocket launches wants to launch a rocket into orbit! Is it possible? After watching some videos and poking around the inventors site I am thinking that if it is possible that Antigravity Research will be the company to do it. Watch the videos for an example of this powerful technology.

 

"They’re made by attaching plastic or cardboard fins to an empty bottle, punching a hole in the bottle top to act as a nozzle and pressurizing the bottle with air from a bicycle pump.Add some water before pumping in the air and the bottle will go higher. Add a squirt of dish soap to the water and it goes even higher.

Schellenberg’s two-stage model is easily capable of reaching altitudes of well over 200 metres.Several years ago, one of his "toy" rockets – actually a Kevlar-reinforced, experimental, single-stage missile pressurized with compressed nitrogen and packing high-tech instruments – flew to just under 379 metres. Based on that research, Schellenberg is now convinced that it will be possible to put a bottle rocket into orbit. In preparation, he’s working on sending a modified two-stage rocket – reinforced with ultra-strong carbon-fibre and fuelled by liquid CO2 – up about five kilometres."

Ford Ranger MP3 Radio AUX Input MOD

at 5:22 am. Filed under Cool Gadgets, Electronic Hacks

There are many products that will allow you to hook up your latest audio gear to your car stereo but none of them will give you the sound quality of this Ford Ranger MP3 Radio AUX Input MOD.

"I recently purchased a new cell phone and wanted to play my MP3’s in my truck. My truck has the factory radio in it and did not alow me to do this. I once used a FM linker to play my MP3’s but found the music quality very poor. This was my solution to the problem."
