One of my latest projects has been a Cable Cam. A Cable Cam, as the name suggests, is a camera that runs down a zip line. Here is mine:
DIY Camera Crane Update.
I have recently made some changes to my DIY Camera Crane. I got sick of the position of the monitor, so I fabricated a bracket to hold it on the pivot point.
I also painted the whole thing with flat black spray paint to make it look more professional. I chose flat black to minimize reflections that might cause imperfections in footage.
I found that my bucket of weights kept slipping off of the crane, go I bent the metal bracket to make it impossible for the weights to slip.
I am currently designing a Pan/Tilt mount for the camera. Let me know what you think in the comments.
DIY Camera Crane
The finished crane at it's highest point
Over the past week I have been building a camera crane, or jib. For those of you who do not know what a camera crane is, it is a device that allows you to take video from really high in the air to really low in the air. The one I built costs about $25.00, but if you have an old stand and access to a welder and some scrap metal, you could build it for well under $10.00.

DIY Electronic Drum Kit Coming soon…..
I have been working on an electronic drum kit over the past few days. It should cost only $5 to make. I will post some pictures soon.
My CNC Machine (a work in progress)
I have started to build a cnc machine. It is small, but should be fine for cutting foam, soft wood etc. The mechanics more or less finished. I am stuck on the controller. The build log is here.

Easy To Build Stepper Controller from Recycled Materials
****I take no responsibility for any injuries, fried computers, or anything of that manner. Follow these instructions at your own risk****
I am 13 I have always wanted to build a cnc machine but because inexpensive parts are hard to find in Canada I have had trouble trying to build a decent cnc controller. The purpose if these instructions is to show that anyone can build a cnc controller using an old scanner. The scanner I used was an old OpticPro scanner. I had previously extracted the stepper motor and experimented with it but not considered it for a cnc controller. All of the controllers on the Internet had a large number of expensive transistors or were ridiculously complex. I finally stumbled across this controller and realized I could build it. By reusing the parts from the old scanner and making the case from recycled cardboard, I am cutting back on my impact on the planet. Also, because this controller is so simple, it only needs one power suply, so, it only needs 1 12 volt (for both the logic and the motors), instead of 1 5volt (for the logic) and 1 12 volt (for the motors). This saves energy, especially when you run it for a long period of time.
If you don’t already know what a cnc machine is, it is a machine that uses special motors called stepper motors to move an object a percise distance. The difference between a stepper motor and a regular DC motor, is that stepper motors “Step”, not spin. if you don’t understand, refer to this artical. There are two types of stepper motors. There is Bipolar, and Unipolar. Bipolar motors have 4 wires. Unipolar motors can have 5, 6 and 8 wires. The difference between these two types of motors is that unipolar motors have 4 coil inside that, when energized in a certain order, allow it to step forward and backwards. This makes them easy to control and is why we are going to use them in this instructable. Bipolar motors only have two coils that can be energized in forward, or reverse. To drive a bipolar motor you need two H-bridges. Because of this, bipolar motors motor controllers are much more complex.
