The Useless Candle

at 1:02 pm. Filed under Funny Hacks

 

Remember the cool Usless Machine? Well now there is a Useless Candle. New idea but just as much useless fun. As soon as you light the candle the system detects that it is lit and blows it out. :)

“The control circuit for this project is built around a 555 timer IC. When light shines on the CdS photoresistor, the voltage at pin 2 drops below the trigger threshold. This sets the output at pin 3 HIGH and activates a power transistor. The power transistor then turns on the relay. After a short delay, the system resets itself and the output is turned off. The two capacitors are included to add a delay when turning the output on and off. The 100kohm resistor and the capacitor connected to pin 2 determine the delay in turning the output on. The fixed 10kohm resistor and the capacitor attached to pin 6 determine the delay in turning the output off. To increase either delay, you can increase the values of the resistors or the capacitors. To decrease the delays, you can decrease the values of the resistors or the capacitors. The power transistor is included so that you can activate relays that may exceed the power rating of the timer IC (200mA). The sensitivity of the sensor is set by adjusting the 10kohm variable resistor.”

Internet Controlled Robots

These Internet Controlled Robots are not available to play with all the time but if you keep an eye on the Twitter channel you will have a chance to have a look and give them a try when they are online next.

“I only put together one robot kit previously, then these two robots both started as Activity Bots.
I hooked up a Raspberry Pi with an HD camera, went through a few wifi options, and got the robot to stream video to twitch.tv and take commands from users via their chat. Later i added the Aruduino for using neopixels and some other future features. We’ve also been making dungeons around the house, made out of cardboard, making quests, and other things for people to do and explore.”

Numechron Digital Clock

 Numechron Digital Clock_1

 

built a very interesting clock called Numechron Digital Clock which is based around a very old clock. It uses an AC motor to keep time which keeps time based on the 60 Hz in the AC line.

“I really liked the Art Deco style of the Model 1364 case and chose to emulate it, although my clock is considerably larger than the prototype. While mimicking the original style, I employed considerable open space in the case design so that the clock’s internals would be visible. A Pennwood employee, F. Greenewalt, patented the mechanism for this type of clock in 1935. He developed an ingenious set of wheels, cams, and levers to flip the numerals and operate the clock. I consulted the original patent to design the mechanism for this clock.”

Power your House from an Old Washing Machine

at 3:55 am. Filed under DIY Hacks

 

Alternative energy is a hot topic. If you are looking to lessen your reliance on the grid you might want to look into a windmill or watermill. In this video Buddhanz shows us how a used Washing Machine can be turned into a power generator. Looks to be a cool weekend project. Most people would need to opt for the the windmill version but the water powered type is very interesting also.

Propane – Oxygen Cannon & Shock Tube

at 3:05 am. Filed under Crazy Hacks

 

This Propane – Oxygen Cannon & Shock Tube is one heck of a project. Looks great and should work very well, don’t think there is a video of this one in action though.

 “When a stoichiometric mixture of gasses is ignited, it is known as a deflagration, which results in a subsonic pressure wave. The principal behind the shock tube is to use the subsonic wave to compress a mixture of flammable gas and oxygen in a tube of specific geometry so rapidly that the driven gas mixture detonates rather than deflagrates generating a supersonic shock wave. In this particular type of shock tube pressure waves have been generated as high as Mach 7.”

Bluetooth Smart Car Project

 

Have a look at the Bluetooth Smart Car Project from Elecfreaks. If you are looking for a new project they provide some nice step by step instructions to get you going on this one.

Thanks for the tip Kathy

“DIY enthusiasts can build their own smart car with simple kits like building blocks, controlled with Bluetooth 4.0 joystick or app.  With simple communication protocol, the car can achieve human-computer interaction.”
