Solidworks eDrawings License Check

So maybe you don’t have access to a 3d modeling package like Solidworks or ProE, but you need to look at models that others have made.  I tried to download the Solidworks free viewer the other day, and this is the message I got:


None of this applied to me, but apparently you aren’t allowed to download if you live in Cuba, Iran, Libya, North Korea, Sudan, or Syria.  Additionally, you’re not allowed to download if Read more »

Light Painting with LED PVC Nunchucks

nunchuck-light-painting-vortexAs outlined in this post, you can make some sweet nunchucks using PVC pipe and wheel lights, but besides being generally awesome, what good are they?  Light painting is one good use, and I’ll demonstrate how I made the vortex shape that you see on the right in the video after the “read more.”

You’ll definitely need some photography equipment including:

  • DSLR or other camera capable of long-exposure shots (this is the camera that was used from Amazon, a Canon T2i)
  • Tripod (optional) – mine came from Walmart, but you could also just set it on a chair or table.

How to Make a LED Light Nunchuck Set

led-nunchucks-complete-paintedAs hinted at in a previous post, I recently made some LED light nunchucks. Although light-up nunchucks aren’t a totally new idea, these are really easy to make, and turn off automatically when not in use.

What you’ll need to make this device is the following materials:

  • 2 “Fireflys” wheel lights (Available from Amazon)
  • 1 foot of 1/2 inch PVC pipe
  • 1 foot of sturdy wire or string

led-nunchucks-light-paintingYou’ll also need tools including:

  • Drill
  • vise
  • Saw
  • 11/16 inch paddle bit
  • 3/16 inch drill bit

Most decently equipped garages or shops should have this stuff, but a drill press or milling machine would be quite helpful for getting the hole started.  The pictures and video after the “read more” should illustrate everything pretty well, but Read more »
