Edge Lit 481 Digital Voltmeter Display

at 11:36 am. Filed under Complex Hacks, Crazy Hacks

 

This Edge Lit 481 Digital Voltmeter Display totally makes me want to build a clock with this mechanism. Can you imagine talking a measurement with this meter that oscillates, it would make a ton of noise. I can see this being great help if you were siting on a stable reading and waiting for something to avalanche.

“These early NLS digital meters used a resistor dividing network and stepper relays to select the display digits. If you see one of these in operation you will hear a lot of mechanical relay noise as the range and digits are selected.”

DIY Plasma Cutter Notcher

at 6:09 am. Filed under Crazy Hacks

 

Make it Extreme shows us how he built this DIY Plasma Cutter Notcher. The video shows the interesting build process. The end result is a great looking jig that handles the plasma cutter with precision.  End end result is a compact machine that can easily make very repeatable pipe notches and cuts.

POP Bottle Rockets

at 9:46 pm. Filed under Cool Gadgets, Crazy Hacks


 

 

Pop bottles normally find their way into the trash or recycling but if you have some time you can make some interesting rockets with them. The 2 stage water rocket above was launched to a height of 864 feet.

 
This one quick to build the rocket portion, most of the bottle work is for looks and a bit of stable flight purpose. The neck of the bottle is simply friction fit to the multiple wraps of duct tape on the pipe that increased the diameter to provide a snug fit. The end of the tube has a cork stuffed in the end with a bottle cap and filler nozzle glued in place. This adds some safety since the cork can easily pop out if over pressured. An alternative would have been to glue an end cap to the pipe and drill a hole to mount the filler nozzle.
 

 

 
This Oobleck filled water rocket didn’t behave the way I expected. Oobleck is liquid and can be poured but when a hard force is applied it firms up. The Oobleck reacts to the high pressure and delays the launch until it is slowly forced out of the nozzle.

 

 

 
This alcohol powered rocket is great since it can be fired with the push of a button. A simple BBQ lighter is used as the spark source, a bit of rubbing alcohol fumes is used to power it but this design should be great with other things such as propane and hair spray.

Keep your fingers clear of these machines! If you are looking for a job that is bound to eventually take off one of your fingers some of these machines are sure to help with that. Fantastic machines but most are very dangerous.

Concrete Creations to Inspire

at 8:02 pm. Filed under Crazy Hacks

 

 

When you think of concrete you probably think about parking garages and and house foundations. Here are some projects that might cause you to add a few bags of concrete to your next DIY project. In the first video you will see that by using a simply mold and a simple jig you are able to create some wonderful bends in concrete. The concrete in many of these projects need additives to allow it to set fast, bend without cracking and not slump when bent.

High Speed Corn Starch Experiments

at 11:45 am. Filed under Crazy Hacks

 

We have seen lots of corn starch experiments in the past. When mixed with water it is a liquid that can be poured but if you shock it with a hard impact it will turn into a solid. There are lots of fun experiments that can be done with it but the TheBackyardScientist has recorded some great reactions with his high speed camera. The best reaction I think is the one at 2:50 where a golf ball is shot at a balloon filled with the liquid, in real time it looks like a normal explosion but in slow motion you can see that the substance breaks apart like chunks of fruit.
