This light couldn't be much easier to build. Mine took about $5 and less than an hour. I used a thrift store transformer and crammed the whole thing into an old DIN plug. As he says, you can use excel to make a disc.

If you want to try something easily available, download my arc template generator. It also prints out 50 and 60 Hz strobe disks at any scale you like. The quality is way better than images, since it generates the pattern locally. It's even better if you use photo paper to print it. I'm not sure how stable the line is where you live, but in many places the use of a quartz stabilized light is a bit pointless. In other places it makes a lot of sense. It takes more time but you can double check using 50 or 100 revolutions and timing with a stopwatch.

Here are a couple of LED strobe circuits - your choice of quartz or
mains driven -

Thanks, Sheldon.
How did you generate the disk?

There's an interesting postscript program I found here -

Re: Strobe circle

The postscipt program above can be modified for 50hz
using the strobe icon count formula on Sheldon's disk
(or here -
HOW STROBES WORK AT KABUSA.COM
)

50 hz 33.33 rpm - change t33 to 90.

For 45RPM, in 50Hz the exact number of strobe dots is not
an integer number.
An approximation is to set t45 to 133, giving
45.1127 rpm

Less fancy solution.
If you have an Ipod Touch. Get frequency generator app, connect Ipod to to amp. Then LED to amp speaker output. Pure fun.... :-)
