I had a pair of eclipse glasses, but I don't know where they are. I want to try and make my own solar viewer, and a pinhole projector seems the easiest option, but I'm concerned that aiming it correctly at the sun will be challenging.
Which is the cheapest, easiest, most satisfying and least injurious way to view phenomena such as transits and sunspots?

We've got an east coast low forming at present...Those things are notorious for hanging around all week long in winter and blanketing the length of the New South Wales coastal lowlands in drizzling rain and overcast - that eliminates the prospect of avoiding it by travel within any reasonable distance. This one is looking no differentIf weather is bad I'll try to find a good place within the next 100 km.

ESA’s Venus Express and PROBA-2 space missions, along with the international SOHO, Hinode, and Hubble spacecraft, are preparing to monitor Venus and the Sun during the transit of Earth’s sister planet during 5-6 June.
ESA’s Venus Express is the only spacecraft orbiting Venus at the moment and while the transit is being watched from the Earth, it too will use light from the Sun to study the planet’s atmosphere.

I dearly hope you say that for the "project to a paper" part, not "use the eyepiece" one.Depends on which telescope you have - if you have a reflecting one (which uses mirrors), don't do it. It should be OK with a refracting one (lenses). Also, binoculars would work just fine for that.
That should be more than good enough if you don't have a big telescope with proper filters.If I try to project the light with my telescope to a paper will be good?
