Interesting screen connection method

I disassembled this "recalibrateable" Caliper and I was wondering why the LCD came off like this with no clear way for the signals to travel to it, I can only assume this is a very interesting way for them to recalibrate it without having to add more pins/pads.

Soldering cobot

Soldering cobot I've made few months ago. It's based on UR5-e cobot with a JBC soldering tip. All is automated.

Changing battery packs in mobile X-ray machine

Changing battery packs in mobile X-ray machine

There are two built-in computers, one running windows 10 (visible on photo 8) and another one running (I think) custom firmware (little screen on top). There were 20 batteries total. You can see internal network switches there, amazing. We did an x ray of a drill to test it's functionality. Also as soon as we discovered it was running windows we had to open paint. We couldn't connect to internet due to security concerns, but it has 4 wireless antenas around it

No idea what I was doing. Attempted to replace 5 capacitors that split from capacitor plague. Burned myself twice, the whole job was hideous.

The Xbox booted up, and it working fine!

10/10 will burn myself again! If you're unsure I'd you can do it or not, just go for it, you can do it!

My second attempt at trace repair (update)

My second attempt at trace repair (update)

The flux arrived early, as well as some cheap helping hands. I used wire instead of blobs and actually repaired the traces instead of the in between this time.

The wires are made out of a torn up desoldering wick, and I used an insulated cable below because I accidentally ripped part of the trace off.

Using flux is amazing, everything just starts sticking to where it needs to go (the wires spontaniously allign).

I cleaned everything with some vodka afterwards.

All buttons on the drone controller work again :)

I made an led earring for my gf!

STM32F103, CR2032, 15 leds, 3 resistors, and one day of work resulted in this.
