Bike camera mount

I'm doing a 7, and 14km downhill ride out at the Grampians shortly, and wanted to take some video of the ride. Microsoft's Hyperlapse video smoothinator is an incredibly impressive piece of software, and I want to run the ride video through it. Not to be confused with normal anti-vibration or stabilisation software, Hyperlapse actually tries to build a virtual 3d model of your path, and reforms the images to construct a moderated flight-path. I can only speculate much of the research for Photosynth went into this one.

I needed a handlebar mount for my phone. Instead of burning cash, I made one from scraps in the shed. :)
It's mounted to the handlebars with a combination of parts from an old bell, and reflector mount. The rest is just some hardwood and polycarb.
I can even tilt it forward for "maps" mode. ;-)

The hole in the polycarb is for the camera so I don't get any refractory glare or other optical effects, something you're probably familiar with if you've tried to take shots through windows etc...
Should work out great. Can't wait to try it. Will upload the smooth-inated videos after the trip.

Small boys' toys with MOAR POWAR!!


Garrick turned 11. I got him a big-boy's sized RC car, though it's important to note that it's a kids toy, not a hobby RC (big boy's) car. There's a BIG difference.
It looks like a big boy's car
And Garrick absolutely loves it.
It even manages tiny jumps.
But dad had a big-boy's RC car when he was growing up, and just plain felt bad about the toy-sized power...so while the boy was in bed, Dad got to work.
The supplied battery is a 7.2V, 600 maH NiCad cell. Absolute RUBBISH. There's space for x8 standard AA's in the car, so I mocked up a battery pack from some 3mm plywood, and made sure everything would fit cleanly inside the car. I even had the correct battery terminal from an old RC car of my own from ~20+yrs ago.
I was going to wire up my plywood battery holder, but ultimately bought a x10 cell battery holder from JayCar for a couple bucks, cut it down to hold x8 cells, and soldered on some heavy wire to the terminals. The car now has an awesome ~10.5V, 2400maH battery pack!!! The difference is outstanding. This car went from a fairly ordinary toy, right into big-boy's RC car territory with a really basic upgrade. MOAR POWAR!!! :D It's super fun to play with now, even for Dad. Burnouts, slides, spinning wheels, crashes... Can't wait for Garrick to see what I've done to it. :D
