Psuedoscope-1 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”.
