LED Fireflies in a Jar (v1.0)

superfro — Thu, 08 Jul 2010 15:37:42 +0000

Me and my wife recently had our first child. I’ve been trying to come up with some projects I can do for the kid. Well, around this time of the year the fireflies go crazy around my house, so we came up with the idea to do led fireflies in a jar. It should be something cool for him to stare at and is easy to build.

Schematics, C source code and hex file are available here on our wiki. If you want to build one it should only take about an hour.

I’m planning on making a version 2 with some changes, stay tuned for that one.

Our first birthday! Seems just like yesterday, HaHa was just a twinkle in Dave’s eye. Check out this video of us enjoying some inkjet-printed confection.

Our CNC Can Kick Your CNC’s Butt!

This video is in response to the one posted here, where a Mr. Riley Porter moves a 35 pound dumbbell with his CNC. We decided to try to trump his CNC’s weight-moving ability by pushing our machine to lift and move first 45, then 55 and finally 65 pounds! We wanted to continue with the weight increases, but did not have a safe way to attach more weight to the Z-axis assembly. Our CNC build is turning out to be quite the beast. Now all it needs is a catchy name…

Our CNC Machine’s First Cuts

bsom — Sat, 05 Dec 2009 02:24:37 +0000

The CNC machine’s construction has advanced to the point where we can begin to cut items. Being a bunch of teenagers trapped in adult bodies, someone decided that we should cut a throwing star from sheet aluminum. One copy of CamBam and 6 minutes later and the star was ready to be cut! After a few adjustments and a bit snapped in half from being dragged through the metal too fast, the cutting was underway. The star took about 10 minutes to cut and was an excellent first attempt at metal production. The next step is to use the CNC to cut more precise parts for itself and help bring about the Robot Armageddon. Special thanks to our newest sponsor, CamBam, for supplying us with a free copy of their most excellent software. Note: The soundtrack to this video may change at any time as we are experimenting with YouTube’s AudioSwap feature.

Robonova-1′s First Steps

Very quick video documenting our Robonova’s first steps, warts and all… A bit rough since he has yet to be properly calibrated or balanced and his battery pack is still hanging off of his back.

Cornstarch Monster Video

A while ago, HaHa member bsom introduced us to non-Newtonian fluids and the idea of using cornstarch and water in conjunction with a speaker/amp and function generator to produce what he called a “Cornstarch Monster.” The video below is an excellent representation of what can be done with this simple yet captivating recipe.

Also, keep an eye on our new YouTube Channel, available here, for more videos, tutorials and technology dissections.

CNC Machines First Production

Squintz — Thu, 01 Oct 2009 03:15:29 +0000

Tonight our CNC showed signs of life. We attached a pen and drew images of circuits, skulls, and Road Runner. The CNC Router was the first project we started working on and it has taken many nights of team work to get to this point. There is still a lot more to do. We started working on the Z-Axis tonight and once that is finished we will have to take most of the machine apart and make fine adjustments to make it as precise as possible. After that there is the long process of mastering the 3D Software.
