I posted this on photo.net back when I first did this to my camera, but now that this forum is here, I'll be linking it up here as well.
It is a little tutorial I wrote to take the very inexpensive (Yet equipped with a rather nice D. Zuiko lens) Olympus Trip 35, and turn it into a manual mode minimalist zen street shooter.

I did something similar to a Trip 35 with a faulty light meter. For mine, I don't seem to recall having to dig so deeply into the camera's innards: I think I just located the (non-functioning) meter movement which would normally control aperture and shutter speed, figured out which positions corresponded to the higher 1/200th sec shutter speed, and held it in that position with a scrap of wire insulation and a tiny bit of contact cement. Which results in a fixed shutter speed (there were only two speeds to begin with...). For aperture, just use the aperture ring. Remember that it won't synch with flash anymore, because flash uses the 1/40th sec shutter speed.
Thank you so much.
Have just done this with an ancient Trip 35 (dug out of a drawer after a long and varied working life, followed by 30+ years of ignoring).
Youngster wants to use it, despite my having offered other 35mm's with working light meters! The magic Olympus created with this camera clearly persists.
We'll see what the first film produces . . .
