Natasha Nox 🇺🇦🇵🇸Is there some (very) cheap controller / tinkerboard with *lots* of GPIO pins?Need one for extensive communication with other ESP8266. I live in an apartment building and definitely don't want to put dozens of them in a massive WPA2-only network, especially not those that control rather important things like door switches. So my goal is to connect them with bell wire and write my own tiny signal library. I need one master device with lots of GPIO + RJ45 though. <a href="https://chaos.social/tags/diy" class="mention hashtag" rel="nofollow noopener" target="_blank">#diy</a> <a href="https://chaos.social/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a> <a href="https://chaos.social/tags/soldering" class="mention hashtag" rel="nofollow noopener" target="_blank">#soldering</a>

s0 Traingirl EraI THINK I'VE DONE IT!!!I just added a regular "pong" transmit and that seems to have satisfied the other side's state machine that I'm still "connected".

s0 Traingirl EraPulled my Sony NW-A45 Walkman music player out to test and it was dead. Opened it up following the great ifixit guide, and yep, looks like the battery got too low and kicked in its self-protection (this prevents a battery from being re-charged or discharged once it drops below a certain point, because the cell is likely damaged and has a higher chance of dangerous failure). This shows as the battery measuring open-circuit/0V.Before buying a replacement, I thought I’d test with a nearby single lithium cell, and it’s happy as Larry. Ok, I’ll order a new battery and it should work fine again!<a href="https://cathode.church/tags/Tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#Tinkering</a> <a href="https://cathode.church/tags/s0Projects" class="mention hashtag" rel="nofollow noopener" target="_blank">#s0Projects</a>

s0 Traingirl EraI wrote a quick blog post about my Soldering Fume Extractor v4 finally. It's a relatively cheap (~AU$120), compact, effective and quiet fume extractor, that uses cheap off-the-shelf filters.Anyone who's interested in making one, check it out. If there's more interest I'll see about building a v4.5 with stronger 7mm ply.<a href="https://blog.s0.is/blog/soldering-fume-extractor-v4" rel="nofollow noopener" translate="no" target="_blank">https://blog.s0.is/blog/soldering-fume-extractor-v4</a><a href="https://cathode.church/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a> <a href="https://cathode.church/tags/s0Projects" class="mention hashtag" rel="nofollow noopener" target="_blank">#s0Projects</a>

s0 Traingirl EraGonna re-post my guide for anyone with a Mitsubishi Electric split-system Air con from the last 10ish years, on how to integrate it with Home Assistant/ESPHome for $20 with one extremely easy, reversible, safe hardware addition!

s0 Traingirl EraHad a dead Soundcraft Ui12 needing repair. Was browning out any PSU connected.Ruled out the CPU board and DSP board, meaning it was the analogue board.Sheesh, three factory bodges! Early unit I guess?Running it current-limited, the inductor for the 48V phantom power boost converter was getting warm.desoldered the caps, and despite being bodgy, they weren’t dodgy. Desoldered (and broke, whoops) the inductor just to confirm it was this section. Yep, board works fine without it! Next I need to find a replacement for this boost driver chip. And the jellybean inductor.<a href="https://cathode.church/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a>

@Rp12Biker :verified:The 3D printer is currently printing something really useful. Our food processor is missing the pusher for pressing potatoes/onions, etc. down.

AI6YR BenNew data:Definitely a Class 2 e-bike. There'a right hand throttle, which works to engage speed.Then there is pedal assist. The pedal assist (appears) to be either on or off, though there's a switch on the left handle... not sure if that's "high" or "low" or what, but there's some kind of difference in how the engine kicks in when "pedaling"... ie how many strokes before it turns the motor on?No speed control with the pedal assist... not sure if that's the expected behavior or not, it just turns the motor on when the disc passes the sensor at a particular time and then turns it off. Except for the "ignition off" (missing key), there is no other button to turn off the pedal assist. So, you're either "pedal assist + throttle mode" or "off". One would think you might wish to occasionally turn assist on/off by pressing a button/switch. (this of course I can fix if I want by adding a switch inline with the "key" circuit.<a href="https://m.ai6yr.org/tags/bike" class="mention hashtag" rel="nofollow noopener" target="_blank">#bike</a> <a href="https://m.ai6yr.org/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a> <a href="https://m.ai6yr.org/tags/bike" class="mention hashtag" rel="nofollow noopener" target="_blank">#bike</a> <a href="https://m.ai6yr.org/tags/hacking" class="mention hashtag" rel="nofollow noopener" target="_blank">#hacking</a>

hobbscOnce I get some spare time, there's a couple of <a href="https://social.sdf.org/tags/crystallang" class="mention hashtag" rel="nofollow noopener" target="_blank">#crystallang</a> things I'd like to tinker with:1. Rebuilding my <a href="https://social.sdf.org/tags/devcontainers" class="mention hashtag" rel="nofollow noopener" target="_blank">#devcontainers</a> template to include the interactive mode for Crystal.

NataliaSiema,I have an idea, but I lack the technical expertise to implement it.I possess an old gasometer, and I currently document its readings by taking a photograph each month and manually entering the data into a Calc spreadsheet, along with the corresponding dates.I want to automate this process though.My initial thought is that a system could capture the images automatically, input the data into a database, and then present the information in a user-friendly format on a display.Would anyone have any suggestions or insights on how to achieve this?Thx<a href="https://pol.social/tags/IT" class="mention hashtag" rel="nofollow noopener" target="_blank">#IT</a> <a href="https://pol.social/tags/smarthome" class="mention hashtag" rel="nofollow noopener" target="_blank">#smarthome</a> <a href="https://pol.social/tags/question" class="mention hashtag" rel="nofollow noopener" target="_blank">#question</a> <a href="https://pol.social/tags/home" class="mention hashtag" rel="nofollow noopener" target="_blank">#home</a> <a href="https://pol.social/tags/smartsolutions" class="mention hashtag" rel="nofollow noopener" target="_blank">#smartsolutions</a> <a href="https://pol.social/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a>

@Rp12Biker :verified:I found a nice way to interact with the S0 counting bus of my three energy meters. Every single used GPIO pin gets it's own interrupt for measuring the time in between last 1->0 change. Every 15 seconds a mqtt broadcast is done to report the average consumption. In addition a one hour and 24 hour sum array is filled too. So no need for PIO operations any more. <a href="https://oldbytes.space/tags/Tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#Tinkering</a> <a href="https://oldbytes.space/tags/Raspberry" class="mention hashtag" rel="nofollow noopener" target="_blank">#Raspberry</a> <a href="https://oldbytes.space/tags/PiPico2W" class="mention hashtag" rel="nofollow noopener" target="_blank">#PiPico2W</a> <a href="https://oldbytes.space/tags/MicroPython" class="mention hashtag" rel="nofollow noopener" target="_blank">#MicroPython</a>

Aaron LongchampsI'm working on the Kubernetes environment tonight and I think for backups I want each relevant container to write into a /backups folder with the relevant data. This local mount (to the container) is really an NFS mount via k8s PVs over to nfs:/volume1/backups/<container-name>.From what I've seen in some of the containers, they have mechanisms to dump the database in some importable format, or a process to export all of their data (e.g. paperless has `document_exporter` and `document_importer`).I have my PVCs over NFS to my Synology anyways, but having them all go into /backups will mean I can tell my Synology to backup that data off-site. Given that this is my "production", that will be the most practical way to get the 3-2-1 rule going.<a href="https://infosec.exchange/tags/homelab" class="mention hashtag" rel="nofollow noopener" target="_blank">#homelab</a> <a href="https://infosec.exchange/tags/kubernetes" class="mention hashtag" rel="nofollow noopener" target="_blank">#kubernetes</a> <a href="https://infosec.exchange/tags/production" class="mention hashtag" rel="nofollow noopener" target="_blank">#production</a> <a href="https://infosec.exchange/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a> <a href="https://infosec.exchange/tags/backups" class="mention hashtag" rel="nofollow noopener" target="_blank">#backups</a>

MoraynerMasto aide-moi. Je bricole un GPS (avec <a href="https://www.navit-project.org/" rel="nofollow noopener" target="_blank">Navit</a> , un logiciel de navigation basé sur OSM).Initialement j'm'étais dit allez, j'installe tout ça sur un p'tit <a href="http://www.orangepi.org/orangepiwiki/index.php/Orange_Pi_Zero_2W" rel="nofollow noopener" target="_blank">orange pi zero 2W</a> parce que faible encombrement et pas besoin d'une chiée de ram et puis je branche le merdier sur l'allume-cigare et marre.Seulement. mon touchscreen a besoin de deux branchements USB, un pour la partie screen et l'autre pour la partie touch, et le 2W il a qu'un usb, donc je me suis dit allez, expansion board, ça encombre plus par contre, c'est un HAT faut empiler les deux mais ça me fait gagner mes ports USB supplémentaires.Et puis je regarde l'assemblage et ça me plaît pas et je me demande si je ferais pas mieux de partir sur un <a href="http://www.orangepi.org/orangepiwiki/index.php/Orange_Pi_3B" rel="nofollow noopener" target="_blank">3B</a> pour réduire le volume et parce que dans la foulée ça me permettrait aussi de par exemple utiliser la machine pour stocker et jouer de la musique, vu que je suis plus inscrite sur aucun système de streaming et que sur le 3B on peut coller un SSD M2. Mais si je fais ça faudra que je fasse des branchements plus sérieux que l'allume-cigare sur mon tableau de bord et ma machine ne sera plus nomade.Par contre si je pars sur le 2W le multimédia c'est mort, y a pas moyen de brancher du stockage dessus outre l'USB et tous les ports seront pris par l'écran.T'en dis quoi, toi? Je reste raisonnable et je fais un GPS bossu sans lecteur audio intégré (et j'ai mon GPS fini dans la semaine), ou je fais la guedin et je pars sur un ordinateur de bord media center de fou (et je postpone le projet d'un bon mois)?<a class="hashtag" href="https://craftopi.art/tag/electronique" rel="nofollow noopener" target="_blank">#electronique</a> <a class="hashtag" href="https://craftopi.art/tag/gps" rel="nofollow noopener" target="_blank">#GPS</a> <a class="hashtag" href="https://craftopi.art/tag/diy" rel="nofollow noopener" target="_blank">#DIY</a> <a class="hashtag" href="https://craftopi.art/tag/osm" rel="nofollow noopener" target="_blank">#OSM</a> <a class="hashtag" href="https://craftopi.art/tag/tinkering" rel="nofollow noopener" target="_blank">#tinkering</a>

s0 Traingirl EraFifth time lucky with modelling this replacement collar to hold the clear viewing window onto a vintage coffee kettle.The thread was an odd square-ish profile with much less trapezoidal draft than the standards I’m familiar with, so I modelled it manually in Fusion 360 with the helix function. It’s a bit annoying that you can’t directly helix a profile, but have to create a square/round one and then sweep the profile along that.Now I will be asking a favour from friends with SLA resin printers to reproduce it in something a bit less thermoplastic, since it’s for a kettle!<a href="https://cathode.church/tags/s0Projects" class="mention hashtag" rel="nofollow noopener" target="_blank">#s0Projects</a> <a href="https://cathode.church/tags/tinkering" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinkering</a>
