Last Notes npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist No test points, no problem! npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist PSA: Don't let capacitors into your life, they'll resist any change in your potential npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist It's only I2C if it comes from the semiconductor region of Philips, else it's just two wire interface npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Finally got ScopeDeck working for #38C3, does this count as #badgelife? npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Step one of bringing ScopeDeck back to life for 38C3. Turns out I rammed the PERST resistor with the m.2 interposer at some point (the scope slides into the bracket blind) and it just kinda came off. Had to solder some magnet wire from via to via to fix it, and fiddle with the m.2 interposer some more to get it working. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist I better conclude this rant before it goes on too long. I guess I sat on this one for too long and it just kinda got out. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist But being easy to use doesn't mean it can't be feature-rich and powerful. A learning curve is fine, but it shouldn't be a wall. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist So if you want to see people using open tools, do what you can to remove those barriers! npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist People who chose to contribute to open source obviously want things to be more open and accessible. And if you take away the barriers they face, they *will* learn and use an open software or tool. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist And this is why I don't believe in judging a open source project on how open the tools/software it uses are. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist My intention was to make it a design for folks to learn from and build upon. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist It's official, ThunderScope has now fully moved over to KiCad! npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist PSA: Tempered glass should not be made into sheets! npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Shot, Chaser: npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Pull-up: pulls the signal up to the rail npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Ghidra or IDA? npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Who gets to be first victim of my evening reverse engineering plans? npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Manager: What should we call this circuit? npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist So what are you actually guaranteed to get with a usb4 connection? Well it's a simple answer, let me pull up *the table* npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist If you're looking for a vendor agnostic way to scan stuff on windows (and not download half a gig of printer vendor software that does ???) check out NAPS2, I just used it and had a rare painless interaction with my printer. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Six years ago I had the idea to make an open source oscilloscope, a scope I wish I had when I started playing around with electronics. Three years ago it was a working proof of concept that I documented online, hoping I'd find people who were interested in making it happen. I did, and I can't express how grateful I am for it! Through our shared efforts, I'm so proud to announce that ThunderScope is finally ready for your lab bench: https://www.crowdsupply.com/eevengers/thunderscope npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist New ThunderScope page is up on Crowdsupply! If you haven't been following the project closely, this is a great time to catch up. I think you'll really enjoy the spec sheet - especially if you were in the market for a certain "very small" scope 😉 npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist If you have a spreadsheet and need to make it a table in markdown for GitHub, I just used: npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Nice, I'm sure the folks on mastodon will get a laugh out of this! *checks time* damn, that's three hours of my life I'm not getting back npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Thanks! It's interesting they mention using different line rates for [PCIe] Gen 2 and Gen 3 - TS can only do Gen 2 due to the Artix-7 FPGA. 10/10.3125 gbps puts it in reach of slightly more normal FPGAs too so that's cool. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Something something plausible deniability, for all i know you measured it lol. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist so what changed? Everything I've seen online about it is either what I just said, or vaguely pointing out that it is different. I don't have access to any non-public data and because of ThunderScope I'd rather not cross that line and get turbo sued by Intel npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Enforced minimum transfer speed, wake from sleep required, dma protection required. All things you could do on TBT3 but now there's no ambiguity. npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist that's pretty much the vibe I get from all public docs I've seen, what's changed behind the scenes? npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist holup, wasn't TBT4 just TBT3 with all the optional goodies enabled? npub177fx7qm9kkrv7guezvcg2zq93aqaa2mhgmxar0xwk04ulqxa3xescjl00d Aleksorsist Skill issue.
