During the summer of 2018, I studied several prosthetic arm designs under the orientation of Dr. Manfred Huber and spent two weeks in his lab at the University of Texas at Arlington.

The prosthetic arm you see below was based on the work of Mahdi Elsayed Hussein. He developed this prosthetic arm as part of his undergraduate engineering thesis in Mechatronics, Oct 2014, entitle "3D Printed Myoelectric Prosthetic Arm." I have modified slightly his upper arm design to fit a bigger microprocessor board - a Beaglebone Black with a Circuitco Breadboard cape. I have also controlled the arm using basic gesture commands of the Thalmic Labs MYO armband ring instead of using several MyoWare muscle sensors. This project served as stepping stone to my Junior Fellowship Project.

I had a budget of around $2K to build this desktop super computer back in July 2017. You could probably build it for less now. I had used this desktop to learn python and run some machine learning algorithms for my Junior Fellowship Project. I have put together a document describing how I put together this super computer . Check the list of parts here.

In the summer of 2017, I 3D printed three sets of this cool low cost eye examination device developed by Dr. Hong Sheng Chiong. I learned about this device via this article at the Ultimaker website - Ultimaker is the manufacturer of my 3D printer, an Ultimaker 2+. I printed the open source product ( the oDocs Fundus) and offered to two ophthalmologists I knew, one in the US and one in Brazil. They really liked the new technology; but unfortunately, these devices are currently only approved to be used in New Zealand. One day they will be able to check the eyes of patients using a portable device like their cell phones, some cool APP, 3D printer accessory, and optics; what will make the diagnostic of eye diseases faster, cheaper, and easier.
