After only 13 years, I am retiring my #Thinkpad#T420s. It did a great job over all these years and I upgraded it to the max, completely disassembled several times. But it was showing its age. I just set up my new personal device, a #FrameworkLaptop 13 DIY Edition (AMD) by @frameworkcomputer - that's a new kind of maintenance-friendly, repairable notebook. Order, delivery, assembly, setup, migration were a blast. No issues, and the installation of @manjarolinux worked out of the box. :awesome:
Apart from common reviews, the two pieces from @pluralistic were interesting reads where he wrote about his experience with Framework, incl. when his device got broken:
The Lost Cause is my next novel. It's about the climate emergency. It's hopeful. $LibraryJournal called it "a message hope in a near-future that looks increasingly bleak." As with every other one of my books #Amazon refuses to sell the audiobook, so I made my own, and I'm pre-selling it on #Kickstarter:
(I went through two keyboards during lockdown. Thankfully, I bought a user-serviceable laptop from #Framework and fixed it myself both times, in a matter of minutes. No, no one pays me to mention this, but hot damn is it cool.)
A closer look at our walnut record frame! These frames allow you to easily slide your favorite records in and out from the top so that you can display your newest album or what you're currently listening to!
I've got a busted consumer product here that has 2 #Holtek#microcontrollers in it. Either one would be sufficient to run this product (a brushless-motor tower fan), but #MCUs are cheap, so why not throw a second one in if it saves a few centimeters of wire?
I'm trying to determine if there's a #standard#serial#physical#layer in use here to communicate from one #MCU to the other. It's one-way communication.
The other MCU pulls the signal wire to #ground to xmit.
The MCUs - Holtek BS82C16A-3 and BS84B08A-3 - natively support #SPI and #I2C, but this isn't either of those.
Each #frame with one byte of data starts with a long (~10ms) low pulse (for #sync, presumably), followed by the #data line returning high for ~5ms, then the data bits are transmitted as low #pulses of different durations for 0 and 1 - 0.6ms and 2.8ms.
The eight data bits are followed by a stop/end bit, always short.
Ich habe eben den zweiten handwerklichen Druck von @GuidoKuehn montiert und gerahmt. Passepartout fand ich nicht passend, also habe ich eine umlaufende Schattenfuge gebaut, um es präsenter zu machen.
Was meint ihr? Bin offen für Kritik und alternative Ideen, denn ich habe noch zwei weitere Drucke zum Rahmen hier... #ink#print#druck#rahmen#frame
