When I taught a two-week photo class to kids (7th to 12th grades, mixed), the first day we made pinholes cameras, then exposed litho film in them. Continued doing so the second day. Then three days of cyanotypes from the litho negatives. Film cameras (35mm) the second week...but we used Ilford C-41 B&W film and a deal with the local camera store to process them. Two days to shoot, three days printing 8x10's. Lots of fun! But it has been years. Have fun, Andrew!
Cool! I bought the square pieces of cyanotype-treated fabric from Freestyle and we did a project making a Tibetian prayer flag sort of thing where we put them on a long string. And I also did the classic soak a big piece of canvas in cyanotype chemicals and laid it out in the sun for a big solargram (found objects, hands etc).Been having a blast! Next year we will also be doing cyanotypes, possibly from paper negs.

I use a #9 oring in my OMs and SRTs.
I use a 675 hearing aid battery with the same O-ring. The voltage is closer at 1.4v, I don't do any compensation.I just tried this out and it works great! A 357 1.5v with #9 o-ring around it is now powering a SRT-201 that's been hanging around on the shelf for several years without being used. The extra voltage meters about 2 stops too much light and so I'm adjusting Ektar down to ISO 25.
