Project DIY Dashcam notes

In order to get a clear image, rotate the lens 0.625 turns left, presuming that the white line that has been drawn on the lens case starts at the bottom.

Making a test photo with the DIY Dashcam

Today I learned that the following command creates a test capture with the raspberry pi camera:

libcamera-still -o test.jpg

A screencapture of the output of the camera test command — The output from the command

A dark image with a window visible. Some daylight shines through the window. — We have an image!

And by golly, it works! So yet again some progress has been made. Somewhat worry that it is blurred, so let me make another one with the lights on:

The same as the previous picture, but this time with the lights on and the room is now visible. But it is terribly blurry — Oh no, this is way too blurry

Well heck. That’s not good. I have still not been ably to install python3-picamera3. Would that be the issue? Weird though. Let’s do another test with a mug at 10 cm distance:

a blurry mug can be seen in the center of the image — Well, that doesn’t look good…

One more test then at 20 cm:

Another attempt at 20 cm distance makes yet another blurry photo — 20 cm has failed too.

Sooo. Not sure what’s going on here, but at least the camera works. 😀

Little update for the DIY dashcam

The progress is slow, but steady. Everything is now assembled and ready to go. Now it is time to find the best opensource dashcam software. I have now hooked it up to the local network so I can poke it everywhere I want.

Loctite 242 and 222, what’s the difference?

In regards to strength, I stick to this rule of thumb:

For something you tighten with a ratchet wrench that is 1/4″ or smaller, you can use Loctite 222.

If the wrench is 1/4″ or 3/4″, Loctite 242 is suitable.

To add to the confusion; If your ratchet wrench is 1/4″, either 222 or 242 will work.

Enjoy getting things intentionally stuck! 🙂

Fixing an issue with my Browning BL22 (Lever not closing)

Update here: https://3xn.nl/projects/2024/08/01/fixed-browning-bl-22-bolt-fault/

After cleaning out my Browning BL22 and replacing some springs, I experienced an issue with the lever on a regular basis. I took it apart again, checked everything, only to have it re-appear again.

Then I noticed that a small plate in the roof of the rifle’s action housing had come loose. After some investigating, I deduced that this was a part that should not move around. Especially since I discovered that I could visibly see the plate when the issue occurred and by pushing it back, I could resume shooting. Another pointer was, that this particular part does not occur in any parts list.

The plate itself, which does not appear in a parts list.

This is how it looks when the plate has moved then then causes a lockup:

So I decided to use some Loctite 242 to lock the plate in place and now time will have to tell whether this works or not.

[Projects] DIY Dashcam update

Alright, that was a lot of soldering and it’s not perfect, but I’m not either. So with that done, I have bolted on the PiSugar auxiliary battery and I think it is time to plug in the camera as well. Now I do hope that I find that one github thing back where all the code was!

Back soon with more progress! (I hope)
