Money Shredding Alarm Clock Project

at 10:18 am. Filed under Electronic Hacks, Funny Hacks

 

If you have trouble getting out of bed a bed shaker alarm might be a bit extreme, you might be just fine if there is a bit of money on the line if you sleep in. This Money Shredding Alarm Clock Project might be just what you need to give you some inspiration. With this clock you are given the beep warning to get up and switch off the alarm since if you leave it too long the cash that is siting on top of the clock will be fed into the shredder. You can switch the $1 for something a bit higher if you are having a late night and will need more persuasion to get up in the morning.

Hack a Sigma Lens to operate with Canon Cameras

Hack a Sigma Lens to operate with Canon Cameras

 

With this hack you will be able to Hack a Sigma Lens to operate with Canon Cameras. The lens being demonstrated is an older lens and the camera that it is being adapted for is a DSLR. The issue is that the signals from the DSLR for adjusting the aperture of the lens are not recognized by the lens. By adding a small microcontroller in the mix, the camera can now talk to the microcontroller and the microcontroller can now control the lens appropriately. The system is not entirely stable so this doesn’t sound like a solution for professionals but for a hobbyist that wants to get some use out of an old lens this might be just the hack needed.

“Components required

  • ATTiny24 x1

  • 10k resistor (colour code: brown-black-orange + precision_colour) x1

  • 47k resistor (colour code: yellow-purple-orange + precision_colour) x1

  • 100nF ceramic capacitor (with 104 written on it, to be precise) x1

Tools required

  • A computer: to program the microcontroller
  • An AVR programmer (I used an usbasp, which can be found en ebay).
  • A solderless breadboard and some jump wires
  • A soldering iron (not too powerful, obviously) and some solder
  • Some screw drivers to open your Sigma lens and pliers”

Wireless Voice-Controllable Smart Home Project

at 3:29 am. Filed under Complex Hacks, Electronic Hacks

Wireless Voice-Controllable Smart Home Project

 

Jiayuan Wang and Sheng Zhang from Cornell University built this Wireless Voice-Controllable Smart Home Project for their ECE 4760 Final Project.

“There are two CPU in our project, ATmega328 and ATmega1284. We set up the wireless communication by two Xbee chips. One of them connects with ATmega328 working as the transmitter to transmit the signal, another one is connected with ATmega1284 to be the receiver. We pick up ATmega328 to be our transmitter part because there is a microphone on it which could receive and store the voice signal from people. When people say the voice instruction, microphone gets it first and then ATmega328 receive it. By the program controlling, ATmega328 will send the signal to transmitter Xbee. When the Xbee is enabled, it will send the corresponding signal to the receiver Xbee by the different voice instructions. When the wireless communication set up successfully, it will send instructions for ATmega1284.”

LEGO Mindstorms Boat

LEGO Mindstorms are very versitile but I think this is the first boat I have seen. Interested in Mindstorm? Have a look at his Youtube channel to see what else he has built.

Build a Robot Hand

at 7:20 am. Filed under Toy Hacks

 

Using some assorted pieces of wood, springs, string and some odds and ends will allow you to make a cool looking Robot Hand! Looks like William Jakespear has lots more cool demonstration of what he makes on his Facebook Page. The hand straps to your wrist and your normal sized hand can then operate the huge robot hand. The springs that were scavenged form a bunch of pens allow the fingers to return the the straight position when you relax them.

3D Printed Stepper Motor

 3D Printed Stepper Motor

Check out this cool 3D Printed Stepper Motor that  Christopher Hawkins made. You can see in the video that it can move quite quickly and not loose any steps. This design would be idea to teach how stepper motors work.

Via: Hack a Day

“This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D printed piece that I designed around these things. My goal was to make something about the size of a business card that moved. You can’t exactly fit it in your wallet but it does indeed move. It just a first draft- there’s lots of room for improvement. It has a step angle of 15 degrees (although the way I’m driving it, it is 7.5 degrees.)”

3D Laser Cutting System

at 6:32 am. Filed under Insane Equipment

 

Nothing DIY here other than if you win the lottery you could turn your garage into the ultimate fabrication shop using this one Mitsubishi machine. It is amazing how flexible this machine is. Programming this thing must be a blast!

 

“The VZ20 series “Offset Head Type” 5-axis lasers provide more cutting power (2000 or 4000 watt choices), quicker response time, enhanced welding capabilities, lower cost of operation and a new control system with to many new features to mention. One of the new M700 series Mitsubishi control features the ability to add a rotary axis to provide full 6-axis machining capabilities.”
