Arduino Marble Roller #2

Here is an update to the marble roller project.  We are using foam board and hot glue for construction.  This is a surprisingly strong construction method for prototyping and projects like this.

In the foreground is a new stepper motor.  Not sure if we will be using it or not for this project yet.

Arduino Bipolar Stepper Circuit

I got a cool little 4-wire bipolar stepper motor and wanted to drive it via Arduino.

I based the design on this reference:

Here is how it looks for real.  Kind of a mess of wires, but you know what?  It works great.

Restoring a Driveway

As part of an utility easement I negotiated with an adjacent property owner, we agreed that I would improve his driveway using fill from my property.

This took hundreds (if not thousands) of tons of dirt and rock to complete.  Nice!

Another excellent project completed by Simondale Excavating from Tyrone, PA.

Plain to Pretty: Rubber Band Gun #6 Anodized

Gord over at Gord’s Garage has been busy with home-based anodizing.  It’s some amazing stuff he is doing. I sent him one of the rubber band gun assemblies, and he did an amazing job on it.

In an incredible amount of detail, Gord has written up and photographed the whole process:

In summary, it went from this mill finish:

To this polished finish:

Amazing!
