new battery and chair mount

From drawing board to being ready to install in single day? Colin, same guy that is now selling wifi robots, salvaged an old power drill to go with the new Lithium-ion battery pack for my chair. More Ardiuno and IOIO protects are possible now that I have a power supply I can remove and charge myself.

aldebaran robotics’ nao

Solid state sensors and high torque servos are getting cheaper all the time, but it is the software methodologies that needed to change for walking to be considered a “primitive behavior”. Any kids learning about robots would, and should, assume that we have walking sorted. Getting back into standing from an unknown state, say on bumpy uneven ground — that’s still tricky. Google is going to lead the cloud...

sexual health education

sexual health education for spinal cord injury These are a few videos we made with Dr. Elliott(sexual health doctor) discussing sperm retrieval and vibro-stimulation with Dr Ip (family doctor). This is basic information for quadriplegics that are going through rehab and want to avoid dangerous Autonomic Dysreflexia while being sexual. More here on things you didn’t know about orgasm on TED talks.

have a go day

Summer is in full swing and we are going to set up the climbing rig in Squamish on August 21st. We have done this route several times, but with everyone in different jobs. I’m going to put all the details here because much of the planning is buried in email and will be best to keep it public. We are going to hog the crag. Shamelessly. Once a year...

better text entry for disability

In past posts, I’ve ranted about resistive vs capacitive screens for typing. Apple’s phone and tablet are great, but as a quad with poor hand function, most will prefer to use a finger nail to type. On my Nokia 5800 this works well and the new firmware has better smooth scrolling (inertia in the flicking though contact list for example). Some technology that came from eye tracking has seen...

the world nuked itself over 2,000 times

This made me feel ill…watching the nukes go off as your birthday goes by. Pretty disgusting way to spend allot of money! So now that the cold war is over, how does the MAD Doctrine keep the balance? If a terrorist bomb goes off, no one knows how allegiances will shift. Lots of books (Tom Clancy) play out the scenario of a nuke or dirty bomb going off and...

super tankers a threat?

Regardless of how you feel about big oil companies, government and hippie activists… light needs to be shed on how many super tankers are in local waters. One good friend that works in the environmental business (yes that’s a business like any other) says that it is not fair to compare the unending leak from the earth’s crust with an oil tanker. Sure.. I’ll take a known volume on...

squamish paralympic torch relay

squamish paralympic torch relay I wish I had more to say in this video. It really took some time for it to sink in. Certainly a once in a life time opportunity. Everyone was really excited and to be honest.. the thing I remember the most was the things fellow torchbearers said. I recall two guys that had autism and were better prepared to answer the question than I...

isaac asimov on bill moyers

I enjoyed the Asimov books my Dad has collected, and very much want to believe that people want to learn. That, in general, people prefer learning to passive entertainment because engaging. Game designers leverage this all the time to get us to strive to get to the next level of a game. Only when we know there will be a test after do we recoil in horror.
