ubuntu wireless

configuring ubuntu wireless setting headless there is nothing cool about a robot that needs wires plugged in — actually it vexes me to no end. running ubuntu in an embedded device can be a real pain when first setting up a new device, like this xaxxon robot pictured. many robots are running linux on low...

ze belgians

climbing with ze belgians a crew from Belgium found the me via the “boosting” news stories and planned a trip to come climbing in squamish. they chanced the weather for mid October but we got lucky, very lucky. that’s what I remember most about any of our big climbs, constantly checking the forecast leading up...
yun REST lighting

yun REST lighting

led lighting with arduino yun progress on the rgb leds continues, here is the code for a useful android testing tool, with a very brutal looking UI.. awful. sliders for the red, green, blue light levels, few buttons for presets and scrolling debug messaging. the only noteworthy thing is defining the range of the sliders...
$100 light bulbs

$100 light bulbs

Philips has a new led lightbulb coming soon for $12, but of course it doesn’t have wifi or bluetooth radios for that price. cheap and hackable led bulbs are being done on kick starter too (but also without a radio). this is because just the wifi radio costs $15 dollars. but.. is a sweet rgb...

drobo fail

drobo fail

I own two drobos and they cause me great pain. Why buy two of them then? Well, drobo won the american business awards for best product, and many more. The problem is that it’s simply underpowered hardware and that the hard drives can’t be mounted by any other system. Now I can say a few...

I chose high torque servos hoping they would be a bit smoother and less “buzzy” when tracking into new positions. with the lightweight gopro camera there is still some jittering, but nothing...

workouts at home

workouts at home Winter has been pretty kind with sunshine thus far, but the rain is coming. Days where I can’t wheel on the seawall, I do more “pulls.” Getting ready for climbing the chief climbs I spent hours on this simulator at home. (see notes on performance boosting) After many versions, I’ve come up...
testing brakes

testing brakes

Here is a short video of us testing the elevation wheelchair with the disk brakes we designed. This project has been both frustrating and rewarding. The tiny details add up quickly. The disk brakes require a bit of extra chair width, and this can be deal breaker for most users. It can make getting into...
data acquisition on arduino

data acquisition on arduino

arduino data acquisition Arduinos can be used in real products, they just aren’t teaching tools anymore. I cut my teeth on 68HC11 using C and the BUFFALO bootloader, mostly pain and not so much fun. sure the paid tools and IDE’s for this chip were pretty good but the were expensive and not hobby grade....
