I've been playing around with KiCad for the first time, and I'm quite the noob. I was going to make my own INA3221 board to simplify (and clean up wiring) I've experienced with other INA boards.

      Ordered a radio from Rokland, the "WisMesh Pocket v2", after the ARROW @W8RP presentation by Blake the other night.

      When it arrives my plan is to work this into my Ann Arbor "Bike Every Park" parks challenge - throw the node in a backpack, stop at a city park, see if there's coverage there, make a suitable note, move on.

      First to try is Burns Park which I know is near @W9TNC which should be easy. From there start mapping out radio terrain.

        @w8emv@mastodon.radio Depending on terrain, a handful of fixed infrastructure nodes can be really helpful in making the mesh usable until it can reach critical mass. It's been cool watching our Austin mesh develop from a dozen people messaging "ack?" to fairly robust coverage through most of the city over the past year.

          @brad The ARROW ham radio club is talking about putting a Meshtastic node up on one of its repeater sites, which would give us coverage to the south side of Ann Arbor. We do have a few trees here to get in the way.

                      @Ricardus@mastodon.sdf.org I saw BEAT in Austin a couple of months ago and thought it was great at the time. But after more reflection, I felt like it wasn't much more than a nostalgia experience. I really preferred the 2017 tour incarnation of KC with Fripp and the three drummers across the front of the stage.

                        @molly0xfff@hachyderm.io This may just be my own personal journey, but I feel like the early-mid aughts were a special time with blogs, blog-rings, RSS, and aggregators. I remember building a proto-social-media site where local blogs were aggregated into a forum for discussion. A friend and I did a weekly podcast about underground rock bands in Shanghai. Pre smartphone photo blogs were amazing. Non-commercial sites like shanghaiist (gothamist franchise) and metafilter could survive on adword revenue. Google search still worked.

                        My memory of the "personal web" at that time is that it felt like it was a linear progression from BBSes, gopher, Usenet, and IRC. More graphical and more widely accessible, but with a lot of the same community spirit.

                          I just realized my good ol' days ended about the time smartphones became ubiquitous. I wonder if that has anything to do with it. How much of that old feeling could be recaptured just by using a desktop computer to "go online?"

                            yt-dlp can also download subtitles, including automatically generated closed-captioning.
                            Formatting and screen captures would take some manual work, though.

                                While playing with my kids at Jinjiang Action Park (锦江乐园) earlier this week, I had a sudden rush of memories from my first time there in 2002-03. At the time, I still carried a paper pocket dictionary everywhere, but my Chinese had gotten good enough that I was able to make friends with people who didn't speak English. A couple of my "local" friends, S and X, wanted to check out this huge new ferris wheel that had just opened up. We walked around the outer wall of the park until we found a some construction debris we could use to climb over, then just hopped the wall. I don't remember what the ferris wheel cost, but it seemed expensive at the time, so S talked an attendant into letting us ride for free. They say the wheel is going to be torn down later this year.

                                Bluetooth audio has been broken on my Ubuntu Macbook since the upgrade to 24.04, but I finally got around to seriously looking for a solution today. After quite a few useless stackoverflow comments, I found the answer. Turns out it was as simple as blacklisting the snd_soc_avs module: https://bugs.launchpad.net/ubuntu/+source/pipewire/+bug/2063150

                                    The article goes on to say that Kaspersky is banned from providing software to US users, which I guess is possible to enforce to a certain extent.

                                            Farmers in Bastrop, TX were hopeful when Elon Musk bought land nearby, but now he’s turning the area into “an environmentally hazardous industrial park.” Authorities won’t do anything because they’re understaffed and “intimidated by their powerful new neighbor.”

                                              @paulrickards@mastodon.social I didn't have a modem for my VIC20 or C64 when I was a kid, but I happen to have one of those VICmodem cartridge near the top of my retro computing project pile. I was thinking about sticking an esp32 serial-wifi thing in the case.
