I'm curious if there's a site tracking new software for vintage platforms such as ssheven which is a modern SSH client for Mac OS 7/8/9. For the occasional retrocomputing enthusiast, it'd be great to have a dedicate

History repeats itself. Check out the story of the Molly Maguires, a somewhat vigilante labor group in PA's coal region, who were infiltrated by an undercover Pinkerton in the late 1800s: https://en.wikipedia.org/wiki&#

Good idea! I'd want to do some research and simulations to figure out how much of an altitude hit I'd take with the added weight of an additional controller.

Yeah taking the Uber route on regulation compliance does not work for space travel.

Really helpful! Thank you! Would you happen to have your source code available anywhere for me to take a look?

I'm not totally certain. I could do a quick C++ POC to see if that improves throughput a bit, but I've got doubts. My other thought is that the SPI interface only can go up to a certain speed. If anyone has deeper knowledge of tha

Hey man! I hope you're doing well! Maybe I'll paint the next one green and white! (For the rest of the world who's confused by this: college fraternity colors.)

I looked into the Feather for a bit, but my experience with the Pi is much stronger, so I felt more comfortable working with that after I determined the battery I'd need to power it wouldn't be too heavy to lift.

I'd like to eventually start working with those more high-powered motors, but for a first flight I wanted to keep things manageable. ... and I also had a 400 ft limit with my permit.

That's exactly it. This thing was pretty heavy with a battery, Pi, sensors, mounting components, etc. I used an Estes D12-5 engine, which is fairly powerful but there are wayyy more powerful model rocket motors out there that I'd
