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
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
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.
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.
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. 🙂
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.
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
