Servo DIY – How to Make a Servo Plotter!

max — Thu, 04 Jun 2009 18:49:07 +0000

For those of you circuit hackers and servo-addicts, you might be happy to learn that there’s a way to make your own servo plotter.

For this project, we wanted to build a lower cost, lower precision XY table for an installation at TeleToyland. The goal is to allow web users to draw shapes in a sand box, so we wanted a simple XY table that is easy to control from a web application. Since we already have the Web to Hobby Servo connection working well for other installations, using a hobby servo was the desired approach. Most homebrew CNC XY tables use motors like steppers and acme screw drives, but we don’t need that much precision, and they are a bit slower than we’d like.

This homebrewed Wii App called Wii Physics is similar to Microsoft’s Physics Illustrator and will let you test out your ideas before applying them in real life.

Wii Physics is a clever little homebrew app. You use the Wiimote to rotate, size and place objects on a stage. Pulleys, ropes, gears and joints can be used to connect objects together, and when you press the play button, a 2D physics system is turned on, causing the objects to fall and interact with each other.

You can download this for free and run it from the Homebrew Channel. If you’re ambitious, you can also download the source, add new features, or base a new game off of it. It’s written using libwiisprite, a library you’ll want to check out if you’re thinking of doing any 2D game dev for the Wii.

We know it’s a pain in the ass to buy a separate DVD player, especially if you have just bought a Wii. Here’s a great Wii hack showing you how to use your Nintendo Wii as a DVD player!

For some reson Nintendo decided not to include the dvd play-back function into the wii.

But it is now possible thanks to some amazing work by Team Twiizers

Kaizo Mario – Homebrew Level for Super Mario World

Here’s a cool homebrewed level for Super Mario World. Of course, you can play the Kaizo Mario on your computer or make your own levels like in this video.

Kaizo Mario is a homebrew level for Super Mario World that’s equal parts evil and genius. My tolerance for frustration isn’t nearly high enough to be able to handle this, but for those of you looking for a gaming challenge, there’s a link to the ROM below.

You can make your own custom levels for Super Mario World with a graphical level editor called Lunar Magic. You’ll need a Windows PC and the original SNES Super Mario World ROM to use it. If you come up with anything you’d like to share, please add it to the comments.

DIY – How to Build a Hard Disk Green Laser Projector!

Here’s a really cool DIY showing you how to build a hard disk laser scanner made from bunch of old hard disks.

My latest tinkery hardware and embedded systems project is a homebrew laser scanner. You know, the kind you see at planetariums- sweep a laser beam around on the wall really fast, and draw vector graphics. Commercial laser scanners have been around for decades now, but buying a complete system is still really pricy, even on eBay. Besides, where’s the fun in that?

There are plenty of examples of homebrew laser scanners on the internet. Many people have wired up a pair of loudspeakers, hard disk actuators, or other readily available mechanisms to an amplifier and used them for simple laser graphics. This will make some pretty wiggly patterns on the wall, but it isn’t a real vector graphics display. The best example I know of for a totally built-from-scratch laser projector (not using commercial galvo actuators) actually uses custom hand-wound galvanometers. Very nice.

This is exactly what I need instead of my whiteboard and pens that wear out.

This is a port of Johnny Chung Lee’s Whiteboard app for the actual Wii. Kudos & thanks to Johnny Lee, Team Twiizers, svpe, shagku and para.

To use this application, you need the following:

* A Wii with some method to run homebrew on it, e.g. the Twilight Hack
* Two Wiimotes. Wiimote 1 is for interaction, Wiimote 2 should be positioned somewhere where it can see your entire screen, but not much more. It shouldn’t be moved after you have started the calibration.
* An infrared Light Pen, very easily soldered according to this schematic.
