Everything is Spinning

at 2:03 am. Filed under Crazy Hacks, What Were They Thinking

 

Our crazy mad scientist friend Rick Crammond (MrfixitRick) had made a cool compilation of the last 5 years of his experiments. You will see some of the successes and failures that he has had over the years.

Magnetic Perpetual Motion Machine

at 9:52 pm. Filed under Insane Equipment, What Were They Thinking

 

Another Perpetual Motion Machine here, this one is magnetic. Not sure how this one was done. Any ideas? It is very convincing, my first guess would be a small motor within the center drum. The real system is demonstrated at the 2:00 mark.

—SPOILER ALERT—

After you are done guessing how this is done click here or have a look in the comments (number 13). Mfsamuel has located an image that shows us how this was done.

VIA Train built in Toronto Basement

at 9:23 am. Filed under What Were They Thinking

 

Do you work on your hobbies in your basement? Most of us do, so what’s the big deal about Jason Shron who built a train in his basement. Well his train isn’t a model, it is FULL SIZE! 

“It took me four and a half years and over 2500 hours to build VIA coach 5647, and it even involved buying the real VIA coach 5647 and taking it apart. My favourite place is on board the VIA train, especially on board the VIA trains of my youth, riding the Rapido between Toronto and Montreal. Now I have this special place in my house.”

Free Energy Generator Head Scratcher

at 6:18 am. Filed under What Were They Thinking

 

Have a look at this Free Energy Generator Head Scratcher. It is obviously a hoax but how was it done? My bet is there is a battery in the meter and a battery in the motor. This way when the leads are shorted out the meter reads the internal battery voltage and when the motor leads are shorted it connects the small battery to the motor. I was thinking that if there was a large enough overhead power lines this might have some possibility but the Mythbusters did there experiments on this and based on their results this coil would not do anything… Any thoughts?

Analog Clock Voltmeter

at 5:43 am. Filed under Complex Hacks, Cool Gadgets, Crazy Hacks, DIY Hacks, Electronic Hacks, Funny Hacks, Insane Equipment, What Were They Thinking

 

What is the voltage on a AA battery? It would be around 1:30PM if you were using this voltmeter! A PICAXE 18M2 microcontroller is used to read an analog value, calculate what time it represents and then uses a stepper motor to spin the adjustment knob to have the clock show the voltage using the hour and minute hands. :)

Read more about the Analog Clock Voltmeter

“The max input voltage for the ADC on the PICAXE 18M2 is about 5VDC.  To tame the input signal for the PICAXE a simple 3:1 voltage divider (10K, 10K, 10K) was implemented.  This limited the input voltage into the PICAXE to 4VDC.  A trim pot was also used to adjust for the input impedance of the PICAXE and to help calibrate the measurement results.”

50,000 Amp Transformer Short Circuit Test

at 1:04 am. Filed under Insane Equipment, What Were They Thinking

 

If you are thinking that this transformer is quite beefy you would be right. Youtube user Photonvids has designed it to be connected to 220V and it has an open circuit secondary voltage of around 4 volts. This means you can safely touch it with your fingers but I would step back if someone was planning to short it out with a crowbar. I guess that might be a good idea if there was no light in the room and you needed the cherry glow of some hot metal to see with. Next upgrade is the copper buss bar since it gets warm during the testing. In some parts of the country they do drug grow house busts based on the large amount of power the grow lights consume, I wonder what the bust team would say if they broke down the door here? No drugs, just the power supply for a time machine…

DIY Neurophone lets you Feel Sound

at 11:03 pm. Filed under Cool Gadgets, Crazy Hacks, DIY Hacks, Electronic Hacks, Insane Equipment, What Were They Thinking

 

The Neurophone was invented by Patrick Flanagan and used radio transmitter that injected sound into the human  nervous system.  Antennas coupled a one-watt 40kHz transmitter to the body to inject the signals. Seems that Patrick was quite the brain since he developed and sold a guided missile detector to the U.S. military when he was 11 years old.

Andreas Hahn has make a modern version of the Neurophone using modern electronics to help him out. Andreas uses ultrasound that is modulated with sound and can be sent directly into the brain.

“To make the ultrasound signal, we’ll use a widely-available TL494 pulse-width modulation controller. This isn’t a perfect solution, so you won’t hear the signal as well as with one of Flanagan’s designs. But it’s a lot simpler than messing around with DSP. And it gives you a chance to experience and experiment with the “Neurophone” effect.”
