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.”

3D Printed Car

3D Printed Car

 

Printing this car took just 44 hours our out of 44 parts. Just bolt on some electronics and wheels are you are ready to drive! Love the design but up close it doesn’t look polished like a metal vehicle but you can see that it goes together in thick levels. What will we see in the future? Instead of customizing your new car by picking a color, interior trim option and accessories are we going to be able to push and pull some of the body features? It sure does open things up for some interesting thoughts.

Hacked Gadgets Halloween Pumpkin Experiment

We crank up the juice on a 5mm LED to light up the Hacked Gadgets Halloween Pumpkin. LEDs have some incredible run time, quite often we don’t need them to run for thousands of hours. If you just need a fraction of the run time just crank up the power and get increased intensity. Watch the long version of the video below to see the math behind the hack. If you just want to see the cray results jump down to the short version. Don’t try to imitate the results since there is an electrocution and burn hazard with this hack. :)

Thanks to my daughter Alexis for carving the Halloween Pumpkin!

Thought it would be fun to jazz up some cookies for Halloween. After some playing around with the power, speed and focus the results are not too bad. You can see the full res images here.

Kettle Cranked up to 10KW and Boils Water in 10 Seconds

at 2:06 pm. Filed under Crazy Hacks

 

Photonic Induction cranks up the juice on their kettle to 10KW, it lasted long enough to boil a cup of water in 10 seconds but it did self destruct during the speed round! Check out the 10 second toaster also. :)

Makers can Design for NASA and Win Millions

at 10:45 pm. Filed under Crazy Hacks

 

Caleb Kraft interviewed Sam Ortega from NASA, Sam explains how the prize competitions at NASA work. Anyone can submit designs for their competitions but only US citizens can win the prize money.

“NASA Centennial Challenges were initiated in 2005 to directly engage the public in the process of advanced technology development. The program offers incentive prizes to generate revolutionary solutions to problems of interest to NASA and the nation. The program seeks innovations from diverse and non-traditional sources. Competitors are not supported by government funding and awards are only made to successful teams when the challenges are met.”

3D Print with Wood

3D Print with Wood

 

Most hobby 3D printers use melted plastic but it looks like we can now print using wood! It gets extruded at 200 degrees celsius. If I were to guess I would think it would be a material similar to MDF which is mainly sawdust and glue, of course the glue needs to be one that can be made soft again by reheating.

“A Thingiverse member going by the nom de printer “Kaipa” recently uploaded pictures of 3D-printed parts that weren’t made of extruded plastic, but a wood/plastic mixture he created on his own. The maker wouldn’t share the process for making the material, or even what the ingredients were, but he did offer to send sample spools of his experimental filament to interested hackers.”
