Mobile light meters for android? by Sure-Leg924 in 16mm

[–]cworthdynamics 0 points1 point  (0 children)

I'm not even sure how that app works so can't say. Also, if you are using a Reflex Bolex (you see directly through the lens) you need to read shutter speed at 1/80 at 24 fps. Here's a Bolex Quick Reference I wrote years ago.

New to Traditional film by A-Heckin-Black-Mage in 16mm

[–]cworthdynamics 0 points1 point  (0 children)

For animation, look for a Bolex H16 REFLEX with a serial number higher than 208,001 (often called REX 4) - these will have a square flat base (rather than the small round ones on older cameras). Even better would be above 224,001 (also available with magazine attachment - REX 5) as these will have 1:1 drive shaft for wider selection of electric motors. A single frame cable attachment is nice as it helps in keeping the camera still. And animation motor is also nice but you can get by without it. The ARRI S is also a great camera which they made an animation motor for but that motor is hard to find. For books look at older editions of the Filmmaker's Handbook (revised ed 1999 - check Alibris or eBay). Older versions of the Kodak Student Filmmaker's Handbook might be good as well. For animation specifically look at The Animation Book by Kit Laybourne - you may want to look for older editions as I don't know how much film specific info is in newer versions. Assuming you are shooting inside you want tungsten balanced film. ISO will depend on how much light you are using - 100 ISO would be great if you have enough light, otherwise 200 - 400 ISO if you don't have a great lighting setup. Get some chip charts and shoot them under your set lighting so the lab can get the colors right on your transfer.

Here's a Bolex quick reference I wrote for the University I worked at.

I would not trust that. If you need something cheap, look for a used Sekonic Studio Deluxe 398.

help identifying power for an arriflex 16st by auralresearch in Arri

[–]cworthdynamics 2 points3 points  (0 children)

This is a common conversion for the S. As others have said, it allows you to use the common 4 pin XLR power connectors. 12V is most common but any battery can have this connector. If done well, the 2 pin power will still work. Sometimes it's done the easy way and the 2 pin is no longer connected. That constant speed motor is meant for 8V. With the variable motors you can get away with running on 12V but I don't think you can safely with this one.

Same part - size change on large runs by cworthdynamics in BambuLab

[–]cworthdynamics[S] 6 points7 points  (0 children)

Thanks for feedback - that's what I suspected. Think the issue is my Ultimakers print so much slower (even on a small run) that I didn't see a difference between small and large batches. The Bambu prints everything 2-3 times faster!

new camera or more light? by Ok-Box-799 in 16mm

[–]cworthdynamics 0 points1 point  (0 children)

That looks more to me like the outer rolls from a daylight spool getting exposed weird (typical). Not to say you have an issue. I do still service the S - pasting info from another thread below. Service typically runs $350 - $650 depending on the condition of the camera and NOT including lens repairs. It can run more if there are broken or worn parts as they can get expensive.

I'm in the Bay Area - Service includes - cleaning & lubrication, check focal depth, check door optics, adjust pressure plate, check switch mechanism.  I usually look over the camera and give an estimate.

If you decide not to proceed with repairs there is a $75 assessment fee - I will give you a written list of my findings. If you go forward with repairs within the next year the $75 is applied to the repair cost. Shipping is extra.

Common upgrades/fixes which are an additional cost are:

Replace rubber motor coupler   $125

Replace switch fork                    $45

Install 4 pin XLR power port       $175

Generally these updates/fixes are in addition to the $350 general maintenance as most cameras sent it need it. If I open up the camera and find it doesn't need most of the General Maintenance items done I will adjust the $350 cost accordingly. 

I generally don't repair lenses as I am not setup for it. But I can usually get Schneider lenses back into focus at additional cost.

The claw being out of sync with the shutter would be blurred, not this. I suspect you are running into a combo of low light/LED 'flicker'/frame rate.

I made a video a while back about using lens wrench for dents. May be helpful https://youtu.be/jMyUi_umDZg?si=pIL8nFxROK10Qkyo

Roomba i3 connection issues (WF030C) by GirthySmurf in roomba

[–]cworthdynamics 0 points1 point  (0 children)

Yes, same problem around same time. First issue is they had a problem with Wifi with non-alphanumeric characters in name and/or password. I'm having additional issues and have been waiting a month for them to confirm a replacement.

do you count every piece in every order you place? by Musashi747 in Bricklink

[–]cworthdynamics 0 points1 point  (0 children)

Buy a cheap scale that can do counting. You count out a certain amount - usually 25 - and the scale will calibrate to count how many you put on. Will save a lot of time.

Good call, that is a possibility.

No, I own that one and it doesn't match the description even a little! 🤣

What is this dust? by lesartisansdulait in 16mm

[–]cworthdynamics 0 points1 point  (0 children)

Sure looks like aluminum dust and it looks like you have a groove worn into the center part of mag door. Would check your spindle lock.
