747 laser cut modelMy daughter had asked about making a plane at “your workshop” (aka Nova Labs) and I thought I’d test one method before I brought her along.

This Boeing 747 model started from a vector 3-view drawing I found online. I cleaned it up in Illustrator and prepared cutouts for 5mm wood.

Definitely less than an hour start to finish.

I think the next try will be to make something a little more 3d by layering pieces of material (I can then get the relative position of the wings and horizontal stabilizer in the right place).

Camera Slider build – Part 1

Camera Slider build – Part 1

Motorized Camera Slider – an introduction.

A while back I teased a project I have been working on for a long time: making a motorized camera slider.

Slider are all the rage lately, giving filmmakers the camera moves of a dolly shot with much less equipment, and also adding motion to time-lapse photography projects.

One of the first ‘cheaper’ motorized models I saw was the Stage Zero slider by Dynamic Perception. Soon after, however, I came across MakerSlide, an extruded aluminum rail with v-channels integrated into the profile. This made it easy to have linear motion components do double duty as structural pieces for small CNC mills or laser cutters. The inventor of MakerSlide, Bart Dring, at one point sold everything himself, including a basic camera slider kit.

I purchased the kit, which included a stepper motor, and got to work. Unfortunately, I had no experience with Arduino at the time, and I wanted to get using it for some projects ASAP…

First pass – Lego NXT

The solution was to jerry rig a Lego NXT motor and controller to the dolly since A: I had it, and B: I could come up with the basic code to get it to work.

It turned out that a Lego Technic axle was just a tiny bit smaller than the diameter needed for the shaft of the 5mm MXL pulley, so it fit well with just a wrap or two of clear tape. The ‘X’ profile of the Technic axles also gave a good space for the grub screw on the pulley to nest into.

The holes in the mounting plate were big enough for Technic pins and axles to pass through without too much play, and while a little janky, I didn’t have to modify or destroy any Lego parts getting everything hooked up.

Stay tuned for build post #2, upgrading the system to an Arduino and stepper driver.

Mazda5 2012 projects

I recently bought a new-to-me 2012 Mazda5 by Mazda (obviously). There are a few projects I want to do on the car, including installation of a new head unit, auto-on headlight kit, and LED daytime running lights.

In the meantime, here are 2 quick videos showing my mini-review of WeatherTech’s DigitalFit Floorliners, and installation of an OEM rear bumper guard.
