Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am merging a couple projects into one and hoping they stick. Let\u2019s get started!<\/p>\n\n\n\n
I\u2019ve been piecing bits of my photo trunk project workflow together now for way too long. Right now, the architecture is looking like I\u2019ll be scanning sets of pictures to a directory on a Network Attached Storage, then I can use a cluster of dedicated microcomputers from another unfinished project to separate and deskew the raw data into individual files. These files will then live permanently on the NAS.<\/p>\n\n\n\n
Progress is rarely linear though. My end goal for this week hopped around quite a bit, but in the end I felt like I did nothing but figuring out how not to proceed: ground work with no structure. Routers are hard when you\u2019re trying to learn them on a schedule!<\/p>\n\n\n\n
In a perfect world, I would have been well on the way to configuring a cluster node by now. In a less unreasonable one, I would have had my Pi 4 OpenWRT ready to support the cluster. Late-cycle diagnostics chased me into an even more fundamental problem with the system: Wi-Fi connectivity.<\/p>\n\n\n\n
During diagnostics, I\u2019m learning about how different parts of the system work. Physical connection points can be bridged for a single logical interface, and Ethernet cables can support separate ipv4 and ipv6 connections. I can\u2019t configure the Ethernet (on either logical interface) the way I want because that\u2019s how I\u2019m connecting to the Web UI and SSH. I end up stuck using two computers besides the two router Pi\u2019s (OpenWRT and a Raspian hack router that actually works) because I don\u2019t like switching my Ethernet cables around on the switch, but I need to do that anyway when I have to copy a large block of text. In short: the sooner Wi-Fi gets working, the better.<\/p>\n\n\n\n
I understand I am essentially working with a snapshot. It\u2019s been tidied up a bit, but bugs still exist. Wi-Fi is apparently one of those things that\u2019s extra delicate; each country has its own region, among other complexities. On the other hand, I don\u2019t know if that\u2019s actually the case, as diagnostics are ongoing.<\/p>\n\n\n\n
I\u2019m probably going to work on this one in the background for a while. The OpenWRT help forum\u2019s polish at least in part makes up for routers being dull to learn. If it takes too long, I do have other projects, so I may need to replace the cluster with a more readily available solution.<\/p>\n\n\n\n
