- Last week I built a shutter speed tester and this week I built a 3D printed enclosure for it.

That came out really well. I still use an older version of SketchUp, ver. 8, because Trimble kept messing with the simplicity and adding bloat to newer versions. You can still download it from OldVersion.
I use the older version to.
I also use SketchUp 17 and love it. Here is an idea I came up with you might like: Often I connect 3D prints with rivets. I light some filament on fire, blow it out, shove it in a hole or just attach to the side of printed PLA. When cooled cut it to length. Now you have a strong shaft. Put it through a PCB board hole, heat it with a match, then quickly rivet it with an aluminum X-Acto butt. Or make short lengths of PLA filament mushroom one end. Line up two .2mm holes, thread your mushroomed filament through and mushroom the other end. Sorry I didn't explain this very well.
I get it!
Really enjoyed watching this project. I don't have a 3D printer, but I plan on building a similar device!
I’m not picking holes as your far more familiar and accomplished with these things, however I would think that you could have the connecting rods/ dowels as a threaded connection, like a helicoid or vice with dense foam pads so the camera is gripped most SLRs and other types are centralised lens with a space either side for grip and for other types a u bar could be slotted in place to achieve the sides. I’d be interested in what 3d printer you have and if you think there are equally as good now on market! Regards DG
Awesome project. Trying to source that phototransistor, not that easy over here in the UK :( Keep em coming!
Nice, I like it.
Should also look at uploading to printables. Ive been going there first for most models now.
Curious how older (one speed shutter) box cameras test. I have a Kodak Brownie from 1950, which is rated by various spec listings as between 1/40th to 1/50th of second.
Really great idea. Any motorbike projects in the works?
Nope
Any chance that you'd upload the stl files? (or email) thanks, m.
Thanks for the reminder. I'll have to do that this weekend. I'll post a link in the video description.
@@HackaweekTV Thanks a lot!
@@HackaweekTV how accurate do you think this tool is? Like, 10% possible error etc...?
My guess is that the sensor doesn't give correct numbers.
I checked it against a know timed light pulse and it's very accurate.
@@HackaweekTV Actually, the accuracy is less a mater of time than a matter of size:
Shutter speed measurement is not only about time, it is also about position. It is a spatio-temporal phenomenon.
The curtains travel speed is about 3 m/s, according to repair manuals.
3m/s = 3mm/milisecond
Your sensor is 3mm large. You have a spatial accuracy of 3mm, so you have a time accuracy of 1 milisecond .
At 1/1000s you have an uncertainty of 100%
At 1/500s you have an uncertainty of 50%
And so on...
@@sebastienroy6281and how could we fix that inaccuracy?
hey can you share also the Fusion files/ stl Files ?
i making one :)
You're not the first person to ask. I'll get them up on Thingiverse and post a link in the description. (:
@@HackaweekTV can i have your email or Facebook? I would like to talk with you
