low powered variable optic 3d models

This is the third series of rubber band-powered vehicles that I've created. There are two photos attached to this message showing the previous version of this design. Until this model is printed, I'm facing some challenges. The main issue I'm...

A USB-powered centrifuge can be constructed for under $10 using a small DC motor (1.5-6V, 4000 RPM) and a DC motor speed controller kit. The centrifuge features a 40mm radius and spins at up to 4000 RPM on a 4.5V/100mA USB port, providing a...

When the winter comes I'll use a similar design to power lights on my bike. I used a Noctua NF-P12 Redux fan and a Lidl (Parkside) battery.  Any fan of the correct voltage and size should work and I think some other manufacturers make batteries of...

This Project Is Powered by an Arduino Nano Pro, an SI4702 FM Radio Connected via Level Shifters, a DS1307 Real-Time Clock, and a Small Audio Amplifier. The Display is Based on Four MAX7219 LED Matrix Modules from Aliexpress. The Left- and...

This rocket attaches to a 1-inch PVC pipe for compressed air-powered launches. Our record distance reached 306 feet, as seen in this video (http://www.youtube.com/watch?feature=player_detailpage&v=TydK261hhFI#t=26s). For optimal printing, we...

Create a simple, fun helicopter model with two propellers, a paper clip, and a rubber band for power. The design is easy to print and build, with a quick assembly process. To print, use ABS or PLA, keeping the body light at 2 perimeters and 20% fill....

It can output a constant 5A at all output voltages, so 20V would provide 100W of charging power. The project is quite specific to my setup, however it does work well as long as the setup is the same. A USB to Lenovo rectangle connector wire is...

This allows the machine to be battery powered. The new motor is driven by a foot pedal based on a cordless drill speed controller. There is a larger handwheel to give a reasonable gearing to the electric motor. These parts can also be used to...

The charger can provide a steady 5 amps at all output voltages, meaning that 20 volts would supply 100 watts of charging power. The project is highly specific to my setup, but it works well as long as the configuration remains identical. A USB wire...

Drill Powered Outboard (Work in Progress) https://youtu.be/Ix5F3YQOyLg Assembly requirements: Print - 1x Propeller of your choice - 1x Handle - 1x Bearing Support - 2x Bearing Spacer - 2x Bearing Cap Buy: - 1x M10 Threaded Rod (I use 1000mm) - 7x M10...

I designed these components to enhance the performance of a potato cannon powered foam glider. Every measurement assumes you're using an 8mm carbon arrow and a 1in PVC barrel. The arrow holes are precisely 7.9mm in diameter for a snug friction fit.

This allows the machine to be battery powered. The new motor is driven by a foot pedal based on a cordless drill speed controller. There is a larger handwheel to give a reasonable gearing to the electric motor. These parts can also be used to...

This innovative design was crafted to overcome the formidable challenge of powering and propelling a miniature race car using the components of a compact quadcopter. To successfully meet this challenge, numerous constraints were carefully considered...

You wouldn’t have to worry about low batteries anymore and at the same time, it would be pretty satisfying to know that you have charged your phone without contributing to global warming. We truly believe that this device will go a long way in...

Hi all, Here is my latest creation an AI powered cat feeder :) Inside is a 3D printed mechanism with an auger allowing to push out the pellets. a servo rotates gears and the auger which is into a PVC pipe. Cat is detected with a neural network...

Yesterday, I came up with the idea to design an air-powered motor for various applications. While the animated GIF at this link (http://www.animatedengines.com/co2.shtml) explains the concept perfectly, my design process is still ongoing. I...

This is a 3D printable air powered engraving hand piece that remains fully adjustable via an internal spring compression adjuster. I designed this version to be very simple to print with no supports, to require minimal post-processing, and...

Working model of a steam engine powered by compressed air. Tolerances between pistons and engine housing are tight but will loosen with use, possibly requiring a gasket between top and bottom blocks depending on flatness and tolerances. M5 bolts,...

Additional parts: Strandbeest (Wind Power Biomimetic Beast) Kit x 1 Bearing (id 5mm od 10mm) x 2 hamster ball (12cm) x 1 (If for hamsters, recommend buying transparent as in the tutorial to ensure their visual field) M3 X 8mm screw x 4 M3 nut x 4 16...

Heat fluid flows down conductive wire-like lengths alongside Super Muscle Actuators running parallel - an innovative alternative exhibiting notably increased power per unit mass ratio in comparison to living tissue. Even including considerable...

The vehicle houses a 400cc, twin-cam, one-cylinder, hydrogen-powered, 4-stroke combustion engine with 4 valves per piston. Moreover, the vehicle assembly is constructed around a 40mm steel tubular chassis. Additional components resemble rear and...

To assemble, you'll need rubber bands: high-power folding a size 117B band in half works best, while size 64 bands (3.5 inches x 0.25 inches) deliver milder shots. You're free to print extra pellets as needed. There are two official ways to launch...
