  • I recommend to start learning fundamental electronics first then move up to microcontrollers (if you’re interested for that) or straight to device. Make a habit of reading datasheet. Reading datasheet is necessity to understand the characteristic of components you’re after.

    While learning Arduinos are good to learn how to handle microcontrollers are interfacing electrics modules. Learning electronics fundamental is good start to put more confident handling electronics (especially low voltage/current stuffs). You may want to tweak lower devices first as higher power devices such as SMPS, Inverter, old CRT TV, Higher power amplifier require more understanding power electronics.

    Afterward steps up to analog electronics (op amp, transistors, mosfets) then digital electronics (digital ics, microcontrollers). At this stage reading datasheet is a must in order to not miss anything from components you are going to use.

    For learning via youtubes, you can try visit eevblog, GreatScott (general purpose), bigclivedotcom (general device disassembly/tear down), afrotechmods (his old videos are still good for explanation). For books, try to check other commenters.

    You can learn at any pace and most importantly have fun :D

    My tip for faster learning is by doing a fun project, it can help to motivate learning. You can start with something simple but adds QoL like making room thermometer using modules and microntroller.

    To be honest, it is first time I discover OpenSCAD, probably due to its nature modeling by programming rather than visually.

    Logically you do want to model by visually especially when it’s more complex geometry and perhaps that’s reason why you may seeing them less getting recommended in general when something like BricsCAD (Education license), OnShape exists.

    I agree Fusion 360 (on Windows) with Free Hobbyist/Personal license is good start to learn CAD modelling for free though as year went by the Hobbyist license becoming stricter and limited in term of policy which raising red flag for hobbyist, not to mention Autodesk also converting users lifetime license into subscription without any notice is enough reason to stay away unless your job provides you those CAD program licenses.

    FreeCAD in its vanilla state (without tweaks) is pain in the butt in term of usability, it’s still bit “hard” to recommend for casual user when they are coming from commercial like Autodesk Inventor, Solidworks and such.

    Recently Ondsel Team created sort of modules for FreeCAD which also marketed as standalone product that lets you to make it functions like Fusion 360 in term of cloud connectivity, their free tier also good even better than Fusion 360 Hobbyist License. They also contribute toward FreeCAD upstream for some general improvement though some of them are exclusive on their own implementation.

    The day FreeCAD 1.0 dropped, I definitely going to try it out because I’m stuck on Fusion (needed for collaboratory work) ever since graduated from college.




  • For everyone who uses searxng, is it great for day to day browsing? Do I require to host my own instance or the setup is as easy as requiring to add “searxng” option on my browser app?

    I’m interested to move away from google as it becomes shitty everyday and loses its effectiveness for advanced query (based on my own result compared during 2013 up to pre covid). Bing have weird result on my region so cannot use it, ddg only for occasional use.

    Thanks!



  • As someone who back then experienced symbian java/java games on my father’ and brother’ phone, I partially agree. For some reason back in 2010-2012, here on Indonesia, cheap Symbian based phone are booming. You can buy a cheap symbian phone with preloaded mp3s and some java .jar games from local phone booth. For me personally I played those java games on my brother Nokia E63 (which is fun) or my father’ Sony Ericson phone (forgot which model). Java games solely responsible for me to discover Gameloft that made those knockoff mobile games (but fun given how simple it was back then).

    EDIT: Perhaps due to difference how regional tecnoloical advancement back then but here earliest I got more modern phone was in 2013 when I got my own Lenovo A369i which running Android Jelly Bean. Learn myself how to root my phone to gain more of my system (back then I was first year of Middle School). Symbian phones was one of mobile era that I fond of because it was very close to my memory of being a kid.

    On similar topic, Blackberry based phone was big here in Indonesia when most of higher class use Blackberry Messenger as form of chatting, never had myself a Blackberry due to how expensive they were on Indonesia
