Attach Sandpaper to a Dremel Tool

dremel-sandpaperIn preparation for a big project I’ll hopefully be able to post on later, I needed a way to deburr and take out a small amount of material from the inside of a wood hole.  My first idea was to use a Dremel Tool (around $50 on Amazon) with sandpaper loosely attached.

I needed to actually widen the hole, so it didn’t work that well for this purpose.  On the other hand, if one simply needed to deburr a hole, I think this could work quite well.

How to do this (and the results) are illustrated in the video after the “read more” link.  Basically, it was Read more »

SC Maker Faire 2014 Results

As alluded to before, I showed off my MountainBeest at the Maker Faire in Columbia, SC.  Here’s a video of the results:

It was fun, and I had a good time at the event.  I tried to conserve battery in the morning, but the legs were functional the whole time.  Along with this, I’m happy that nothing shook loose or jammed “catastrophically.”  My GoPro ran out of juice after a few hours, but that’s not too bad since it was transferring video over WiFi.

The components I used from Servocity performed quite well, including the 6 RPM gearmotors that powered each set of legs, the PWM relay to allow them to be controlled, and the servo pan-tilt device that my GoPro was mounted on.  Thanks to them for their sponsorship, helping me to build this ‘Beest without breaking the bank too badly.

I was happy to meet everyone there, and thanks especially to Jay for setting up the event.  For a little broader look at the cool events there, check out my article on Make’s blog about this, or there’s a huge set of photos available here.

Columbia, SC Maker Faire

If you are going to be in the Columbia, SC area this Saturday the 14th, I’ll be showing off my “MountainBeest” contraption at the Columbia Mini Maker Faire taking place at the EdVenture Museum.  It’s apparently already set up there, and from the picture, it looks awesome.  Pretty cool to have an “exhibit” featured in a museum.
