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.

Arthur Benjamin – Mathemagician

at 10:23 pm. Filed under What Were They Thinking

 

Are you good at math? Not sure you will think that after you watch the TED Talk featuring Arthur Benjamin, the Mathemagician.

“Dr. Arthur Benjamin is both a professor of mathematics and a magician. He has combined his two loves to create a dynamic presentation called “Mathemagics,” suitable for all audiences, where he demonstrates and explains his secrets for performing rapid mental calculations faster than a calculator.”

ABB Robot made of LEGO

ABB Robot made of LEGO

 

Computer engineer Lassee Laussen and software engineer Ken Madsen built this ABB Robot made of LEGO bricks. It was an 8 month build to recreate the complex 6 axis machine. If you are interested in seeing some other interesting projects from Lassee and Ken have a look at Brick It.

“The LEGO version of the IRB 120 is so accurate that it mimics every shape and curve. It also has all 6 axes for the same freedom of movement that the real thing has. Sure, it won’t be moving as quickly as the original or carry the same payloads, but nonetheless it is a pretty spectacular recreation of an industrial robot that finds itself in assembly and pick-and-place operations in factories all over the world.”

Drone with a 80KV Stun Gun

When you get tired of flying a regular hexcopter why not kick things up a notch and install a stun gun on the thing to protect your property!

“In the video above, CUPID (short for Chaotic Unmanned Personal Intercept Drone) takes down an intern. He doesn’t get up with ease.”

Dummy Load Water Bucket

at 8:36 am. Filed under What Were They Thinking

 

When you need to ensure your power supply is up to snuff a dummy load is often used when it isn’t feasible to test with the real load. You will often see this on a big scale when load testing emergency generators. Normally you would use a large resistive load that is air cooled by fans.  Mikeselectricstuff demonstrates his array of resistive loads but for a new project he didn’t want to build another one for his new project so he did some out of the box thinking. He shorted the output of the power supply with the right length of light gauge wire to draw the load needed. Normally this type of wire would heat up and melt with any significant load so he put it into a large tub of water to allow for direct cooling. The wire he selected is enameled so that it doesn’t short out to adjacent wires in the tub but provides for virtually no thermal resistance so the water can draw away the heat.

SMD Soldering on Hot Sand

at 10:43 am. Filed under What Were They Thinking

 

When Oliver Krohn isn’t using an Arduino to control the temperature climate chambers he is soldering SMD parts on hot sand! I guess the skillet and toaster oven is not cool anymore. :) He is using a bunsen burner to heat the sand but anything would work as long as you can get the correct temperature. Might be a little hard trying to follow the reflow curve of some parts but in a pinch it looks like it should work well. I guess you could even get a really good temperature measurement by just jabbing a temperature probe into the middle of your hot sand. Oliver is tinning the pads with solder but if you started from cold sand or drop your board onto the bed of hot sand I am thinking you could also use some solder paste and place your components prior to heating. This might be a great backyard soldering experiment using a bucket of sand heated using a fresnel lens on a hot day.

RumbleRail – Floppy Disk Jukebox

 If you still have a few floppy drives left over after making your Floppy Drive CNC machine have a look at making some music by making a Floppy Disk Jukebox!

 “The overall setup is completly modular. Each floppy is connected to its own floppy driver (rrfdc), which in turn speaks I²C with the main board (rrcmd). On power-on the main board auto-discovers the connected floppies and adjusts the software to utilize the available drives. In theory the amount of floppies connected to RumbleRail is only limited by I²C address/bus restrictions.

The most important feature of RumbleRail is the ability to run standalone. After being powered-on, the main board scans the hotswapable SD card (rrsdc) and lists its content on the display. The user can browse through the selection using the rotary encoder and, once a song is selected, the main board decodes the MIDI file and streams the notes to the floppy drivers.”
