Make a Simple Dust Collection Box

preview-imageRecently I saw a downdraft suction box used to collect fine dust sanding somewhere online and thought I could make it very simply with 2x4s and plywood. Using some scraps of each that I had around my garage, here’s what I came up with:

Though after production, this came out to be a 7:00 video, you can probably figure out the basics from the picture above. A few details that might not be especially evident come at around 2:00, where I cut two offset holes to allow my Rigid vacuum nozzle to fit properly, and around 3:00, where screws are used in a sort of non-traditional way to retain the top.

Results are shown at the end, and it appears to be somewhat effective, if not “vortex-like.” I should note that this could also likely be used for vacuum forming, where thin material is heated, then sucked around another part. I haven’t tried the process myself, but it definitely seems to have its uses.

For another take on this design, here’s a suction box that looks slightly more complicated to build, but features an angle on the inside to help channel the vortex. Perhaps the results would have been better with that inside. It wouldn’t have been too hard to add to my build, but I was trying to make the simplest build possible (OK, I perhaps the machine screws weren’t that simple) so this is “left as an exercise to the reader.”

I put a lot of work into producing this video, so hopefully you like the results. I started putting things on YouTube to simply host it for this site, but I’ve been trying to put quite a bit more effort into production etc. I’d encourage you to subscribe there to see what other videos come out of “JCP!”

On another note, I’m thinking of changing around my YouTube playlist format to hopefully make things easier to find and play. Please let me know what you think about the video in the comments below, or perhaps via Twitter here! As always, thanks for reading and watching!

More StrandMaus Footage

StrandMausAfter my first video attempt, I decided to make another clip, this time featuring the external camera more prominently than the FPV GoPro footage. FPV footage is from my Hero4Session – now known just as “HeroSession” – Amazon.

The results, as previewed in a little GIF above, I think are much better. In the FPV portion, I featured a view of the front legs/linkages prominently, as I think this is the most interesting part of the design, that and the actual camera turret setup. Check out the whole video below!

You can see the original video, as well as a little more information in this post.


Introducing the FPV StrandMaus


If you’ve been following this blog for any length of time, you have seen my various iterations of a remote-controlled vehicle based on Theo Jansen’s StrandBeest. My latest version is much smaller, so I’m calling it the “StrandMaus” (Beach Mouse, instead of Beach Beast). Check it out walking around in the video below:

I plan to explain how it works in further detail in another video or post, but what really sets this apart from my other versions is that I’m using thrust bearings from Servocity*, along with shaft collars, which allow the legs to be tightened more than the loose configuration I tried before. Also, the gear train is partially based on something I saw on Twitter from Jo!, using gears instead of linkages to transmit power between the central shaft and the legs.

Probably the most visually obvious feature of the FPV StrandMaus is the GoPro camera (a tiny Hero4 Session – Amazon) attached on a Servocity Pan/Tilt system. I used this on my first StrandBeest model which was neat, but was never able to walk on its own. In theory, one could log onto the StrandMaus’ camera and view it remotely while having it walk around it’s environment. Certainly I’ll have to experiment with this further in the future!
