HOW TO make a Pseudoscope
Rob H. writes “How to make an $800 pseudoscope for less than $10. My first post on this subject involved prisms, this time the scope is made with mirrors. I’ve never seen the MX-3 in person but I recommend buying one just because they look so cool, but if you can’t afford to spend that much this post will show how to make a pseudoscope for less than $10, and also how to construct better versions for a little more”.

Across the country, kids compete to construct amazing works of art and help put a dent in hunger.” The winning entries from the 2005 competition are pretty amazing. My favorite is the 3,160 can model of a breaching shark. Very cool. The tornado too. Heck, they’re all cool! Be sure to check out the slide show of past entries as well. There’s a great entry of an Etch A Sketch made from large Hunt’s Tomato cans–complete with artwork on the screen–that looks to be about 7 feet tall!”
A business called “Robot Village” has opened in Manhattan — basically a robot store where you can buy, rent and even learn to build robots. The store also throws robot theme parties for you, and sells all manner of robot-related gear. The Robot Village is even planning a BATTLEBOT CLASS. [
All electronic devices send out eletromagnetic waves, so does your monitor – and your monitor does it all the time at very high frequencies. High enough for your short wave AM radio. All you have to do is display the “correct” image on your screen and your monitor will emit the “right” signals. Tempest for Eliza displays pictures on your screen. One for each note in the song.
