Pinholes are a ton of fun. I've been using a TLR converted to a pinhole
- a very simple and easy system to work with:
http://www.markcassino.com/b2evolution/index.php/kinoflex-tlr-pinhole?blog=9
On my camera, the pinhole is not very good - its only ~ f180 and was
drilled, not a laser hole. So lots of distortion but not the real long
times that come at higher f stops. But, the finder lens in the TLR
corresponds well with the pinhole "lens" so framing shots in very easy,
and the finder lens is actually quite bright. Just set the camera to "B"
mode and shoot away. Looking at my camera - it was modified simply by
removing the glass lens and replacing it with a pinhole. No need to
change the shutter or anything else. Seems like a simple modification
for the mechanically inclined, and even "broken" tlrs - clouded lenses,
stuck apertures, inaccurate shutters - could be converted so long as the
shutter B (or T) mode works and film can still be spooled into it.
I tried using a 6x7 Pinhole body cap from this place:

Much better pinhole than the TLR but you can't frame up the shot with
the body cap in place - so you get into lens swapping. (A finder that
corresponds to a normal lens might work and I have one (for the Pentax
Q) that would fit into a flash hotshoe - if only the 6x7 had a
hotshoe...) Also the body cap is not light proof so either you get light
leaks or use some kind of tape to block the light leaks... More fiddly
than the TLR approach but it produces some nice results.
Have fun!

Not that anybody has expressed any interest, but it is a slow weekend

My recent 4x5 sheet film holder enablement has reignited my desire to
get into pinhole cameras. I've had such a hankering since at least
back to 2009 when I bookmarked a bunch of resources. Never having
enough books, I ordered Brian J. Krummel's "The Pinhole Camera" (which
has great reviews) and it arrived late this week.
The thing that fascinates me about pinhole is the stretching of time
through looooong exposures. It causes you to look at scenes in a
different way. Sort of like using a 10x ND filter, but different. Also
the extreme "f-stop" means that everything is in focus (extreme DOF).
I also like that there are a million different ways to make pinhole
cameras: flat film plane, curved film plane, anamorphic film plane...
each with different results. You can use photographic paper for the
negatives or film for the negatives.
I also like the whimsy potential of many pinhole cameras (oatmeal
boxes, empty paint cans, wooden cigar boxes, etc.) You can also
exercise your woodworking skills, if you like. This 13 part YouTube
video series is a little slow and tedious, but also very educational
(showing workarounds when things don't go 100% according to plans)...

In other enablement news, I've got a thing for Pentax preset lenses
and I found a minty 1957 Takumar 135mm f3.5 with original leather case
and the metal lens cap that says simply "PENTAX". I've wanted that
lens cap for a long time. So it is on its way now. It will find its
place alongside my other preset lenses, the Macro-Takumar 50mm f/4,
the Tele-Takumar 200mm f/5.6 and 300mm f/6.3, and the Takumar 200mm
f/3.5. I've also got a preset Auto Vivitar 85mm f/1.8 but I've got
some difficulty (T-mount or otherwise) because I can't make it reach
infinity focus.

I call upon the PDML Collective Hive for ideas (and, optionally,
LINKS) to fun things to do with 4x5 film holders. I tripped across a
box of some, priced too cheaply, at a local antique store and bought
the lot intending to sell the majority.
However, I intend to keep 2 or 3 for myself. One obvious project would
be to make a pinhole camera. Anyone have a favorite design (or plans)
to share? (PS: International Pinhole Photography Day is April 24,
2016)
I've also seen some ultrawide (think Hasselblad SWC) cameras built,
but those would require the future purchase of a wide lens/shutter
combo that is outside my planned expenditures for at least a while.
Alternative ideas are also welcomed. I have no 4x5 camera ATTM, but I
suppose buying or building one of those from scratch would be another
possibility. I do have a 4x5 enlarger and paper up to 20x24 that I'm
itching to do SOMETHING with.
PS... if you are interested, a good video 5 minute video on Pinhole
