T-Scann 8 - project page
Super 8 / Regular 8 film scanner
Stepper motor must be Nema 17, it is a size standard, it is sold by different manufacturers.
Stepper motors are available with 1.8 degrees
(200step) and 0.9 degrees (400step) T-scann 8 programmed for 1.8
degrees. If you have a stepper motor 0.9 degrees, the arduino code must
be adapted.
There are 2 variants shaft 5mm round and bevelled edge
this is what you should look for. The shaft should be around 20 mm
long, there are several variants here as well. Furthermore, there are
not always contacts on the cord, so it is good so you do not have to put
it on yourself since the cord is not too short, on mine they are 30cm
shorter than so they should not be, preferably a little longer. Below
link to one that. There are certainly in several places buy what suits
you depending on where in the world you live.
If the distance (Stepper ‐ motor ‐
distance.stl) does not fit the one you get, say, I will post a custom
one. The shaft protrudes 18mm above the plate, with my stepper motor.
Almost everything can be ordered from mouser.com free shipping from 400skr or 50euro. Delivery worldwide.
This list contains 20 different items (81.46 Euro) the exel file can be imported directly into mouser Shopping Basket.
Arduino Nano can be found cheaper. Compare the price when shopping for other things

Warning for some stepper motor cables
Temu.com has a lot of stepper motors like this

Highlight the film
White LED CRI 95 / 4000K seems to be good
Note "Cree CXA1304" is available in several versions some are only CRI 80 the one I
recommend is
CXA1304-0000-000C0UA240H look for this in technical data or compare carefully.

As an alternative to the XL4005, this works well

about brightness but I'm guessing 150-300 mcd.

Phototransistor WP7113P3C if you can't buy
it then it must
have sensitivity around 900nm and clear not blue! this
has sensitivity even for shorter wavelengths 390-395

Back‐panel‐contacts
Contacts are expensive, these contacts fit in the panel.
Search for
these in your home countries maybe you can find these cheaper?
Inside the scanner, these short cables are preferably needed under 1 meter.
USB-A to mini-USB / Arduino Nano depending on the manufacturer there are also USB-MINI and USB-C
USB-B to USB-A / Raspberry PI
HDMI to Micro HDMI(Type D) / Output Raspberry PI
If you have difficulty finding any part or have any questions, send an email to brev@torulf.com and I will try to help you.
* This connector has become expensive and difficult to buy.
Will choose a new connector and probably update theback panel
