1100 Paintballs Shoot to instantly make a Picture

at 5:28 am. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, Crazy Hacks, Electronic Hacks, Funny Hacks, Insane Equipment, What Were They Thinking

 

Adam and Jamie from Mythbusters built a huge paintball gun that can shoot 1100 paintballs in an blink of an eye. When the balls crash on the canvas you can see a picture of the Mona Lisa. This was an attraction at an Nvidia event, I wonder how much the unit cost! I guess when you have a huge budget your mind can do wild.

iPod LCD Hack

at 5:30 am. Filed under Complex Hacks, Electronic Hacks

 

If you need a display for your next project you could probably use one from a defective Apple iPod however after looking at the iPod LCD Hack details I think purchasing a display that has a simple interface may be the ticket in this case.

"Looking for a small, cheap LCD for a possibly large-scale project, I decided that the 2.5" QVGA TFT in the Ipod Video may be worth a look, as cheap clones of it are available from Hong Kong via Ebay.. Not finding any info on this unit on the net, I decided to investigate myself, & bought a faulty ipod on Ebay to dissect. The hard disk was dead, but I could get it into service test mode, which was all I needed to fiddle with the display to see how it was driven. This display should be drivable from most microcontrollers ( *I’ve not yet verfied that it can do 3.3v I/O. If not, you’ll need alot of resistors, or a level shifter), however the 16 bit data bus will need rather alot of I/O pins. If you’re running from something like a NXP LPC2xxx ARM processor, this may not be a big deal, and you may want the speed of the 16 bit bus."

Pedal Powered Snowplow

at 5:32 am. Filed under Funny Hacks

 

Winter seems to be just around the corner. This Pedal Powered Snowplow seems to be a good idea, say goodbye to the sore lower back and have fun driving the plow through the fresh powder. Only problem I can think of is the plow seems to be quite bug and may not handle anything deep.

"One day while watching the show “Monster Garage” he was inspired. He immediately turned off the TV and started sketching some ideas for the snowplow. Within four months of working after hours and week-ends Blake had a functional machine. After some cutting, welding and bolting Blake had a frame with wheels that he could sit on. Even better, it worked! The joke in the Blake household was Blake calling his wife to make sure she didn’t shovel the driveway before he got home so he could plow it with his invention. "

Build a Steel Shotgun Pneumatic Cannon

at 7:17 am. Filed under Crazy Hacks, DIY Hacks

 

You can have some dangerous fun with some pipe supplies from your local home store. This Steel Shotgun Pneumatic Cannon is a good example of that. For more items like this have a look here.

"The Steel Pneumatic shotgun is a very simple metal spud cannon, so see how to make it in this video. It is specially designed for C-cell batteries, but will work with any projectile (granted it makes a good seal in the barrel). It is also very easy to construct and disassemble considering it is put together completely by treaded fittings."

Tachometer made from a Bicycle Computer

at 12:50 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks, Other

 

A clever way to use a bicycle computer as a poor-man’s tachometer.  While I’m not sure about installing it in my car, I’m sure it’ll come in handy down the road for another project. 

"Sometimes you just have to know how fast a wheel or shaft or motor is turning.  The measuring device for rotational speed is a tachometer. But they are expensive and not easy to find.  Its cheap and easy to make one using a bicycle speedometer (cyclocomputer). In fact, the only thing you need is a functional cyclocomputer that reads speed in miles per hour. You won’t damage it, so you can even ‘borrow’ one from your bike, or add it to your bike once your done!"

Balancing Robot

at 5:37 am. Filed under Complex Hacks, Electronic Hacks

 

Futz’s Microcontrollers & Robotics has a few balancing robots featured, the second version was built on the non functioning first attempt. It is still a work in progress but the build log is good and it will be interesting to see the progress of this project all the way to completion. Still seems that accelerometers are quite pricey, has anyone found a good deal on these anywhere? See a video of the work in progress after the jump.

"Woohoo! I now have an Analog Devices ADXRS150 gyro on a Sparkfun breakout board (left). That, in combination with my Dimension Engineering DE-ACCM3D accelerometer, should get this thing balancing once I get the software squared away. After playing with it for a while I moved the gyro down to the centerline of the axles where I believe I’ll get the best response from it (right). The gyro is ultra sensitive and really "locks" the tilt attitude of the robot. You can feel it trying to keep the robot’s tilt right where it is. But it drifts, as all gyros do and pretty soon the bot is leaning way over."
