Cobbled but working is a win!
I haven't done any exposure testing of the Royal blue vs Pink. If any is lost, I haven't noticed in use. With this latest build I'm getting similar times with the Green vs Pink channel. a typical...
The item I ultimately got most recently was https://www.amazon.com/gp/product/B09MRK3CHC
When I was first looking at them several years ago, one of the LED retailers has posted the spectrum graphs...
I've built / rebuilt a DIY LED 5x7 head for my Durst several times now.
First was with standard RGB LED Strip lights - worked as proof of concept, but the Blue isn't the right wavelength for VC...
looks good!
I'll have to attempt a 5x7 soon...
Amazon - search 'polysorbate tween'
drop me an email address in DM and I'll send you the .stl files
I have an Ender 3 v2 that I got for less than $200 about 9 months ago. I had no 3d experience before then.
In that short time, I've learned simple CAD (TinkerCAD) and with that have designed and...
This is a plate holder. I wanted to avoid hinges/flaps. But after doing this, I might try it.
I get the garolite from McMaster-Carr. Last batch I got was 1/16" x 12"x24" .
Here's my version of 3-D plate holder - this a 5x7 I designed and printed this summer. I based it off my 1903 wooden holders. Parts are printed to mimic the slotted wood, including joinery that...
Here’s my solution for most barrel lens - almost as simple but a bit more controllable than the Galli shutter. Black matte board with a slit cut in the middle. With practice you can get fairly...
Very nice - thanks for documenting!
Nice!
Totally reasonable - I have an 8x10 B&J with a setup you describe. I built a lensboard / box with Packard Shutter mounted in the back to use a nice petzval. Air hose goes though the Lensboard - no...
Press on series filter step-up adapters - to - any normal mm filter size have always been hard to find in my experience. Often it's a 2 step process - for example Series VI to 'MM I don't want', then...
I Use construction type foil-faced foam insulation boards in the window of my darkroom. Cheap easy to find at hardware stores and home centers and very easy to cut. Cut it 1/2 in. larger than the...
I use the foil backed pink insulation foam panels in the window of my darkroom. The foam is easy to cut, deforms easy to mold itself around minor bumps. The foil makes it 100% lightproof. Its dirt...
I made a decent 11x14 washer from 1/4" plexi with a less than professional grade table saw. 2 chambers each able to hold 4 prints comfortably with dividers, water from first cascades into the next. ...
You can get decent digital milligram scales from major online retail site for less than $50
Mine came with a calibration weight too.
Graduation weekend for my son. Will have to keep you in suspence till next week.
Mostly McMaster Carr stuff
WOW that is quite a cannon indeed!
My ULF scissor lift ver 2.0 is making progress - I ordered a 1/2 acme/jack screw. It's a 36 in. rod, and it was delivered in an ** 8 ft ** cardboard tube.
Nicely done!
I like the eye-bolt tie-downs.
Indeed - those wheels look great!
I think with the success of the scissor lift, I may move on to ver 2.0 rapidly with the addition of some larger wheels. Love the rickshaw concept!
And thanks to...
Last weekend I joined the world of ULF with my latest project. I was given this copy camera body over 20 years ago from a customer back in my camera sales days - It has moved houses with me and sat...
Love it - simple and elegant solution
Indeed. My early version only had mixing chamber + frosted plexi and that was a bit hot in the center. But adding the second layer of plexi with an inch or so gap between evened things out pretty...
Thanks!
I enjoy your many DIY posts. JB indeed has many good things on his site too - it was a great proof-of-concept jumping off point for this project.
As I've been dabbling with handmade emulsions and alt processes, I have recently been longing for standardized exposure for my plates as I test different formulas and variables. I needed a...

well done!

I have a 14x14 copy camera i'll be working on this summer and need a transport system for it
Interesting results! I've got a few extra hangers I will try modifying when I have a chance. I also have some 4x5, 4-up hangers that I have had really noticeable issues with surging at the holes in...
Thanks Peter!
The D70 wasn't very hard to modify. There were a couple of thin-film ribbon cables that were a bit tricky to re-seat properly. But even with a couple of reassembles to get said ribbon...

Another vote for hot glue - I have several older lenses without flanges that I've hot glued to a lensboard. No failures yet.
That is not to say there isn't a learning curve to using hot glue...
I have a 12" f4.5 Radar in a Betax 5 - the front and rear cells have identical threads. I can put either cell in either position in the shutter.
I also have a Velostigmat f4.5 in a Betax 5 - same...
I use foil-backed foam insulation board to plug up windows - available at any home center. It's easy to cut with a simple knife, and deforms a bit to wedge it in for a tight seal. Cheap. Easy to...
I've been souping my own glass plates in kodak hangers for a couple years now. Like film, if you're only doing one or 2, tray is fine. Beyond that it gets tedious and I switch to hangers and tank.

I separated my LED strips by the same distance as between each LED on the strip - about 1cm if i recall. I'm sure a math person could tell me reasons why this is not the best, but it gives me a very...
I built a similar UV box as OP with flexible strip LEDs (not weatherproof) for salt printing and have been very happy with it. Not the brightest, but I haven't had any problems with banding or uneven...
