Practise copying and sending Morse code using a scheme of sessions developed by Rob Brownstein of CWops. The speed, Farnsworth speed.
The W8BH Morse Tutor is a great project for learning programming, for learning about hardware, for beginners to learn the Morse code, and for people who already know the Morse code to increase their speed, both in copying and sending, with either paddles or a straight key. You can build the Morse code tutor for $20 in parts.

You should see the window turn red and the progress bar move steadily across the window as the Audio Book is created.

Practice sending and receiving code.

Steve Weber, KD1JV has designed a inexpensive device to help you learn or improve your cw skills virtually anywhere. We are calling it the KD1JV Code Trainer. You can practice receiving code at 5-30 wpm just about anywhere. It is small enough to slip into your shirt pocket and using some ear buds, you are good to go. It is small, highly portable, and runs on a simple coin cell. The device uses an Atmel ATTiny13 microcontroller. There is also an led that will flash in receive and send mode as code is generated for hearing impaired users.

The receive function sends random five character mixed letter, number, and punctuation code groups. There is also an optional setting for Farnsworth character spacing.

The send function works as a normal code practice oscillator, but accepts either a straight key, bug or paddle. A single lever paddle or Iambic B can be used. Paddle speed is adjustable from 5-30 wpm. There is a jumper block to select either normal or reversed paddle side preference. It has auto-sense on startup that automatically detects either a straight key/bug or paddle connection. Adjustable gain on the output will drive a small speaker, earbuds, or with a simple cable you could attach one of the many external speakers now available for larger group use.

The standalone through hole kit has all the components except a user supplied CR2032 coin battery that mounts in the pcb battery holder. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 2. Assembly time should be less than an hour, depending on experience.

About

There are many Morse Code training tools, but most of them require installing or are platform dependent. I really liked an online tool by AA9PW, which generates audio at the server and streams it to you. This has a number of advantages - totally platform independent, and it will work with basically any browser ever. But when I looked at it the other day, it was no longer working (this may have since been fixed). This encouraged me to make my own tool, along the same lines as AA9PW's and adding some of my own ideas.

Using the HTML5 Audio API has a number of advantages - far less bandwidth used, you can change the speed/pitch as it's playing, and so long as the page is still hosted it will always work, since no processing is done at the server. The disadvantage is you need a fairly recent browser to use it, as the Audio API was only introduced a few years ago.

Receiving (copying) Morse Code is generally much harder than sending it. I had previously made a few quickfire Morse tools, but they were very limited. I've also built both software and hardware Morse Code USB keyboards.

Speeds

Slowing down morse code evenly can make it quite difficult to hear the 'shape' of the characters. In the Farnsworth method, characters are sent at a reasonable speed, so they sound correct, but with spaces between them so the overall word speed is reduced. As you learn, gradually increase the word speed until it matches the character speed.

In the Koch method, you should start at full speed but with a limited character set. When you can copy just two characters with 90% accuracy, add one more. When you can copy those three with 90% accuracy, add another, and so on. There is a recommended learning order which I've put into the dropdown box. These are chosen at random but with weighted probabilities so the most recent two characters are most likely to appear.

Using the custom character set, characters are chosen with equal probabilities.

When you feel ready to move on to real blocks of text, be prepared to slow down again. Morse Code is designed around the letter frequencies in the English language, with E and T (the most frequent letters) having the shortest codes. So copying real text will be faster than random characters at the same character speed.

The speeds are determined by the word PARIS being 50 dot-lengths long. See the wikipedia page on Morse Code for more info about the timing.

RSS

Although you can paste an arbitrary block of text into the source box, it is pretty difficult to do so without reading it. Using RSS is a simple way of fetching meaningful blocks of text that you won't already be familiar with.

Despite my ambition to have this entirely Javascript-based, the same-origin policy means some server involvement is unavoidable. The RSS feeds are bounced off a PHP file on my server so that an AJAX request can be made without breaking this policy. This is possibly open to abuse so I've only given it a fixed set of available feeds, but if there is an RSS feed you want added to the list feel free to message me.

Wikipedia actually has an entire API for fetching its content, and it supports JSONP which would avoid the need to bounce it off my server. However, it isn't really intended for this sort of thing, and grabbing the featured article's description is rather complicated through this method. Easier just to use the RSS feeds in the same way. The feeds are located here and here.
