Always seeking cheaper ways to source materials to cut with the CNC, I came across some tutorials on building a charcoal fired aluminum foundry.

Some external resources if you want to try your hand at it!

Be extra careful if you decide to embark on this project!

Here are some photo’s of our progress:

This summer (2011), we built this giant swing in our backyard — it’s over 20 feet tall and swings out over the hill behind the workshop. Total cost was under $40, but we had the pressure treated beam and some of the hardware lying around, we just had to buy the cable and some extra 5 1/2″ lag bolts. Definitely is lots of fun and great for taking a breather between coding-sessions to meditate.

My friends Colin, Brian and Joey can all be spotted in the shots — until I get their photo’s I’m nowhere to be found

Here we’re cutting the stator plates that will hold our coils, and showing off the coil winding jig on the variable speed drill press.

The Serial2Parellel library was developed to work with shift registers like the 8-Bit Serial-In/Parallel-Out Shift Register from TI. It makes it easy to set the state of all the bits on one to four chips chained together then push all that data out through a data pin on the Arduino. This library has no other dependencies and is very lightweight. It’s free software, if you use it please just leave me a comment I’d love to hear about your project!

Source Code:

The source code is available at:
https://github.com/ElectricJack/Serial2Parallel

Download:

Serial2Parallel.zip

To use it download the zip and extract it’s contents into the folder:
[ArdinoSketchbook]/libraries/Serial2Parallel/

Then just #include “Serial2Parallel.h” in your sketch and you’re good to go!
Check out the example for further assistance!

I have worked on a couple projects now on the arduino where I’ve used the LCD 117 controller to run LCD’s from Modern Device. I wrote a small arduino library to make working with the component even easier. I’ve since decided to release the code in hopes someone else will find it useful.

Download Source:

• LCD117.h
• LCD117.cpp

To use it download the source files into the folder:
[ArdinoSketchbook]/libraries/LCD117/

You’ll also need the NewSoftSerial library installed in your Arduino sketchbook’s library folder.

Then just #include “LCD117.h” in your sketch and you’re good to go!
