Simple Camera Pan & Tilt

I wanted to create an unlimited 360° +/- pan with 180° tilt sync'd to my camera shutter (Prism)


So I got some scraps from the garage and made this thing - I know the quality is really lousy

I'm somewhat unsure if the fuel tubing couplers will be strong enough (bottom/pan coupler isn't connected yet)

Both mechanisms move "fairly freely" so . . . we shall see

 

It's a start - more later

Arduino Controlled Brushless R/C Vehicle?

Hello,

I would like to be able to use an Arduino and control an r/c car

Goal:  When I reset the Arduino, the car moves forward a small distance, then pause for "n" number of seconds and then loop for "x" number of times

I have a good grasp of r/c and a little experience w/Arduinos and I'd like to be able to vary the forward progress of the car - move it just an inch or so each time the program loops - steering isn't important (right now)

Thank you

Battery Power - Where Do I Find Answers?

 

Hello

I need to use one battery to power 4 items, each is identical and requires 5V DC and can use up to 2.5 amps under full load.  I would like to use the lightest battery that would provide about 8 minutes of use for all four of these devices.

I would like to have all four of these powered by one 5V battery but how do I calculate the amps &/or discharge rate for this power requirement?

Where do I go to find the answers to these questions?

Thank you

:)

 

 

Weekend Project: Either Create a 3-Axis Printer or Finish My Delta Robot

Hey Everyone,

I'm making an effort to create either a very small 3-Axis Printer/Router or finish the Delta Robot this weekend

I have other things on my list of "must do" but I'm going to make an effort to get one of these projects done

If I build the Printer/Router, I realize there are a zillion examples already out there but I want mine to involve a different design (not that I expect mine to be better than anyone else's)

That's all for now - photos & build log updated soon

My Delta Robot

Hello,

I built this robot and using the Arduino, I created a sketch that makes the end effector go up and down.

I'd like to make the end effector do more than that, of course, so does anyone know what I need to do next in order to control the end effector in the same ways that others are doing?

I have a functional copy of Processing, if that helps.

Thank you!

Why Do I LOVE New Projects?

 

Especially ones I've designed - especially when it seems like nobody else has done this before?

 

This should be as much fun as it will be frustrating . . . more soon . . . yeah c'mon!

I received the parts so I could finish my Printrbot and it's nearing completion . . . woo hoo!  :)

 

 

 

 

 

 

I also dabble around with quad copters

Here's one of my home brews . . . flies really well. My first quad using the Naza flight controller - very nice controller.

Comments About the Book "Making Things Move"

 

Hello,


As someone who has been a contributing author for a fairly popular CAD book, and who has been a technical writer, I am no longer as critical as I used to be before I added authorship to my repertoire of career achievements.
