We obtained a mysterious box of 1960s electronics. I reverse-engineered it and with much effort, we got it running. It turns out to be a test unit for testing NASA's Up-Data Link, a system from the Apollo moon landing to control the spacecraft from the ground. Let's take a look inside... 1/n

Some people prioritize setting up a site and making logos rather than working with the community to address the issues using what we often refer to as "responsible disclosure".

NASA used this "Up-Data Link Test Set" to test one of the electronic systems onboard the Apollo spacecraft. I've been reverse-engineering this box and I found that it uses LED-based opto-isolators. I didn't realize that they had LEDs and optoelectronics in the mid-1960s, so I investigated... It turns out that opto-isolators existed back then but were extraordinarily expensive. 1/N

Funny FPU trick I discovered yesterday to detect arm64 or x86_64 architecture at runtime

The Densha de Go 64 controller has a spot for a pocket watch so you can make sure you're on time and feel like a real conductor! I'm using an old one as a placeholder, but you can get Densha de Go branded ones perfect for that slot (though they can get pricey!)
