Raptor: 3-D printed prosthetic hand

I designed the Raptor to be a basic terminal prosthetic hand that could be 3-D printed. There are only 4 pieces that are printed and they can be made at a home printer.

I designed the Raptor hand for a design competition on GrabCAD. As of this post the competition is still up.

If you would like to print the Raptor yourself here are all the files that you need

If you would like me to design a custom application prosthetic for you feel free to contact me.

Here was a demo of the prototype. I used shockcord and paracord as the cables which is way to bulky. In future I will likely use small steel cable a maybe just rubber bands.

Portable Event Solar Phone Charger

This solar phone charger is designed to be deployed at outdoor events like weddings and concerts so that people can charge their phones. Normally extension cords or large cumbersome solar umbrellas have to be set up to fill this need.

The one issue is that people have to supervise their charging and the charger itself can be stolen. In a future iteration I will add essentially a port for a bike lock and locking compartments for phones to sit in while charging.

I would also like to spread the usb ports around the  edges more so that they are not so condensed. It will change the experience from waiting in line to just walking up and plugging into your own space.
