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:

solidworks_requirements_edrawings

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.
  • Remote camera trigger (optional) – Less than $5.00 from Amazon, or you can check out my review of the RC6 infrared trigger.
  • LED nunchuckssee this post for how to make a set, or you could swing a light around on a string.

Once you have this stuff, you’ll want to start the nunchucks (or whatever you’re using) spinning close to the camera.  Open the shutter, preferably using Read more »

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 »

How to Supercharge your HTPC with AutoHotKey

In this post, I wentautohotkey screen capture over the benefits of setting up your PC to be used on your TV as a Home Theater PC.  This has worked for me for well over 2 years, but one thing that was a bit annoying was having to find things and navigate around with the trackball (using this IOGear wireless keyboard from Amazon).  The range on it is great, but as the batteries wear down, the keys, and especially the trackball, become unreliable.

While researching some stuff related to my learning Python, I came across the program AutoHotKey.  Unfortunately, it seems to be only for Windows, but I’m sure there’s a Linux or Mac alternative out there (let me know in the comments).  Apparently it’s got scripting and macro capabilities, which is really cool, but for my purposes I simply wanted to assign a few hotkeys to open: A. Netflix, B. ESPN3, and C. A workout video that we have stored on the hard drive.  I’m sure we will assign more, but that’s probably 90% of what I use my HTPC for.

Fireflys Wheel Lights – For Wheels or Other Inventions

fireflys-led-lights-with-packagingWhile ordering some parts for my Large Hexapod on Amazon, I came upon these little lights that attach to your bicycle or automobile valve stem.  They were priced at $1.63 at this writing, and were hard to pass up given my interest in light painting (See my CNC light painting article) as well as mountain biking.

I wasn’t sure what to expect out of these devices, given the insanely low price for a set of 2, but according to the packaging that they came in they are:

  • Made of high quality material
  • Different color for option
  • The light will be off when the vehicle stops,onwhen it runs, and flash when you’re driving at night
  • Bring more color to your car
  • Bring more enjoyment to your drive

That’s what it said at least (in all caps).  Actually this isn’t too bad for a Chinese translation.  Although most of the points are debatable at best, Read more »
