Thanks Niglyn! I guess there is no need in designing a new film-gate box for your tester, we can use the one from srozum's project, all the 3D printer files (STL) are on his Github. I understand that you don't want to be dependent on someone else's project, but there is also no need to reinvent...

It's been a while since I visited this forum and unfortunately the build of my tester has been on hold for a while. Now I see your picture with the LED light source and the sensor box, I find this a very interesting option (I was messing around with the alignment of the lasers the whole time)...

Can anybody please enlighten me? I've got the tester ready to go and tested my first camera. It's a camera I've used quite a lot, so I know the shutter speeds are within tolerance (at least within my acceptable tolerance, I only shoot B&W). So, not very suprising, all the shutterspeeds (accept...

Thanks again for the quick replies. For now I'm gonna remove the battery and power it with the usb, it's clear to me I need to do some more research before I'm gonna use a battery safely, without damaging my Arduino :)

Right now I'm relying on the onboard VR. But I'm still a bit struggling on the best way to connect the battery. I have connected it to the GND and VIN port so to use the onboard VR, but I'm using 3 AA batteries, which results in 3x 1.5V = 4.5V. From what I understand, the input power on the VIN...

Today I finally had some time to work on my project, so here are two pictures of my creation. It's not finished yet, the laser and receiver will go inside the grey boxes, but are now temporarily mounted on top with some blu tack. I also used an old cutting board and some pieces of wood from an...

Did anybody perhaps did some testing on what hole size is best? Is it the smaller the better, or is there a point where the hole is too small?

I have actually build one, but it is just a first test to check if everything's working (this is my very first Arduino build). So it's just a couple of wires and components connected. If I have some spare time (which is limited since I just became a daddy :D ) I will finalize the project and...

I finally got it to work! First of all I had to adjust the contrast pot (thanks for the tip!), when I did that I noticed the screen only showed blocks. After 5 minutes of searching the web I found out my wiring was wrong (switched A4 and A5), so now it works! Now it's time to fix everything in...

The code did load OK, I got no errors. I will try to adjust the contrast pot, hopefully that will be the easy fix ;) I was searching for the serial monitor on my PC, I guess I did find it, but it was empty, so I wondered if I had the right one. Hopefully I will have some time soon to test these...

I finally have found some time to build this tester. But, since all this is completely new to me (Arduino, code), I can't figure it all out, excuse me for this silly question. I have connected everything, uploaded the latest code to my Arduino Nano, checked the port of my LCD (0x27), but my LCD...

Not yet, I do have all the parts, but haven't got the time yet to put it all together. Also have to learn a bit about the Arduino, this is my first project :)

Leica M5, Foma Fomapan 400 @ 400, developed at home, Rodinal 1+100 semi-stand, Patterson tank. Gotta love the Rodinal grain :D

Nice!

Quite pricey, but I actually like it
