I got a whole set of Japanese container cars, which were pretty cheap because it came without the containers. I designed, 3d printed, and painted a whole bunch of them to fix that

I’ve made another PCB to control my model trains. I got a bunch of switches that can be controlled electronically, and I wanted something that could do that via WiFi
A black pcb with a bunch of terminals and a green raspberry pi pico 2 w. All of it next to tracks and two trains

I've got a simple light sensor hooked up to the system that's logging temperatures around my house and it captured the partial eclipse of yesterday

Madelief While she has her home in one of the houses close by, this cat really likes to hang out on the tiny grass field behind the station. And it's always nice to see her when I pass by.
A cat called Madelief napping on dry grass and leaves. parts of the station are visible in the background

The Eiffel tower One of the few photos I planned before going to Paris, and the reason I took a Fuji GSW690 with me.

On Friday I picked up the six rolls of color film I shot in Paris, and edited them over the long weekend. The 6x9 photos are nice, but I'm pleasantly surprised how well the photos I took with my Rollei B35 and Harman Phoenix came out.
