This project shows how to build a LED holiday tree using a custom made circuit board. The circuit board is made using a Dremel rotary tool and doesn’t require any etching chemicals. You use the Dremel tool to cut a copper into a tree shape and route the two separate PCB sections that will power the LEDs. The LEDs and resistors will be soldered at the surface of the board. The result is pretty nice. Check the construction PDF on the link below.

Researchers at CMU and Intel are attempting to map and understand human brain activity well enough that individual words can be detected. Currently, giant MRI machines are being used but the future holds smaller devices that can be worn like a helmet according to Dean Pomerleau, senior researcher at Intel. The efficiency and productivity of word detection will be superior to existing technology that allows an operator to simply control a cursor. This technology will no doubt make its way into robotic telepresence applications including remote surgery and construction in dangerous environments such as the ocean and space.

I Really Really Want a Cyborg Kidney

Yesterday, I got a kidney stone. I would describe what it feels like to get a kidney stone, but I’m not sure that words can do it justice. If you’ve had a kidney stone before, you know exactly what I’m talking about, and if you haven’t, be thankful. The only reason that it’s something to look forward to is so that you’ll be able to contrast it with every other pain you’ll ever experience and think, “well, this may be bad, but at least it’s not a kidney stone.”

Soldering ADuM4160

Long overdue USB Isolator Assembly Guide is finished. It describes building Analog Devices ADuM4160-based USB Isolator kits. The guide contains component identification, step-by-step building instructions and soldering hints. Those who has their isolators already built will find useful powering and tweaking information at the end of the guide.

If you see any errors or have any questions, please let me know!
