Hey guys, if you’ve got a noisy pot and there’s no dust in it then you might want to check for DC in the signal path. No coupling cap between stages can cause that.
There must be some retro-computing types who would relish figuring out how to fix Voyager’s and other satellite’s issues from a distance. I wouldn’t be surprised if someone has a Voyager emulator.
NASA has also let organizations “adopt” orbiting satellites whose missions have ended. [ https://en.wikipedia.org/wiki/International_Cometary_Explorer ] is one and it did involve a fair bit of cash. I also remember someone on AstronomyCast talking about a satellite that NASA let their school (or whatever) take over a retired satellite – and being told to just ignore that encrypted signal overlayed on its data stream.
Maybe some school or whatever will make a bid on Chandra too.
Also, kudos to magtape and Core Rope Memory. CuriousMarc did an in-depth video on Core Rope. [ https://www.youtube.com/watch?v=hckwxq8rnr0 ]
The discussion about Dave’s Skunk Project & USB vs. BT got me thinking that it might be a good idea to ask Michael Ossmann back on the show. Great Scott Gadgets has been working on “Cynthion – A multi-tool for building, analyzing, and hacking USB devices [1]” and according to their latest Crowd Supply status update (30.4.) they appear to be “on track for June shipping!”. Thus I guess he’d be kinda uniquely qualified to answer questions about both protocols. Also, even if Dave goes for BT, I’m still demanding a demo of the product! Could do a video comparison of both protocols and then decide which one to use?
2xAA batteries is going to be an interesting challenge. I mean I’m not sure how far Dave wants to go but the specific instructions that are required to do “one sampling” take a certain amount of power (considering one actually reads the datasheet to see how to program the devices and to not just throw microSnakes at it). It would be kinda cool to do a measurement of how much power each protocol would require for the “same output”; also taking into consideration the other ancillary electronics required as they’d differ based on the protocol I suppose. From that baseline one could do a rough estimate on how long 2xAA would be able to power the device. Yeah sure one could just ask ChatGPT to do an estimate but that wouldn’t make for an interesting video.
ps. Greetings to the fellow nerds commenting on these posts; very much authentic “community engagement” :Dd
pps. NEXT EPISODE BETTER BE BAD TO THE BONE \,,/, (>_<) ,\,,/ lmao
