how 2 electronics??

i wanna get into tech and learn about electrical engineering and how to program/code and stuff but my main issue is i just dont know how to proceed im a professional procrastinator and i just waste time every day doing nothing pic is an alarm clock i "fixed" (i didnt have the power cable for it so i soldered an usb cable to it) my issue is even though i can solder i dont know how stuff works (and i dont have components to mess around with), i dont know anything that good about electronics or how to program stuff another issue is the fact that i dont have a lot of stuff and i have about 0 money on me i dont know where to start/proceed on learning this stuff hardware hacking seems interesting to me but i just dont have hardware to mess around with, other than a satellite receiver that i dont have a satellite for and my attempts to "hack it" didnt go all that well please give advice/resources, i really dont know what to do anymore

Hardware hacking: https://nostarch.com/hardwarehacking If you want to get into elec eng, you should learn about basic electricity (Ohm's law, kirchoff laws). Then you can learn some digital logic, and try to build circuits with them. Then try learn more about electricity in depth with some physics books on electro magnetism. You'll need to learn some calculus and linear algebra stuff. I studied elec eng, I'll post the books i used through out my degree, one sec

>>79690 I don't remember much of the books I read lmao, I mention the ones I do know. Ok, so for Mathematics everything you need to know, you can learn from K.A Stroud's Engineering Mathematics. Mathematical Methods for Physicists and Engineers is also good as well Learn some C programming and Assembly language, it'll give you some more details on how computers work. Learn some networking. In Electrical Engineering, you mostly learn about layer 1 - 4 (Physical layer - Transport layer) in the OSI model. Stuff like HTTP or FTP, is more for CS people I'm pretty sure. Once you learn about DC circuits, learn about AC and the concept of impedance. Complex numbers knowledge is important for this.

>>79663 >im a professional procrastinator and i just waste time every day doing nothing Before you do anything else, you need to solve this problem. Otherwise you won't get anywhere. If you get that done, you could start with any cheap Dover or Schaum's book on basic electricity. If you don't have any math at all, two dirt cheap and really good books to get you going are Simmons' "Precalculus Mathematics in a Nutshell" and Keisler's "Elementary Calculus An Infinitesimal Approach". If you get that far, you could go on to "Practical Electronics for Inventors by Scherz and Monk, and an engineering math book as previously suggested. Have fun.

I'm new to this subject as well, and i'll be reading this thread and pursuing its suggestions. the first thing i'm looking at and reading about is the raspberry pi. I guessed it was a good place to start, given they're made mainly for educational purposes.

>>79663 go on ebay and look for old broken electronic items and fix them. older electronics from the 70s and 80s have simpler pcb's that can be fixed by hand. opposed to modern ones which are too small and fabricated in such a way that you can't.

thanks for all of the replies and suggestions! >>79690 >>79691 ill check all of that out soon >>79696 ill check that too, im just not particularly sure how to combat the procrastination since i really can barely control myself in that aspect >>79698 i wish you luck on your journey, and fun >>79705 i wish but i currently dont have much money (and no job) and i couldnt convince anyone that lives in the same house as i to let me borrow money to do stuff like this

I would recommend especially for low budget collecting/finding lots of things you can mess with / use as parts.. See if you can catch things like old tvs (maybe not crts or microwaves - I would be careful with those =) your family might through out, also going to a thrift store is something you can do as well. 120v Led bulbs have voltage regulators in them (be careful to discharge capacitors) and you can find peizo buzzers sometimes in alarms. You can desolder transistors and parts as you need. Its taken me a long time even to learn stuff like the relationships in ohms law. If you can afford getting it a kit full of different resistor and capacitor values and random other components is helpful to breadboard circuts with. There are tutorials on how to use an Arduino as a volt meter and a basic oscilloscope. Its fun to learn by having a goal in mind then learning/modifing basic circuts to put together and test. some fun channels i'd recommend are saveitforparts and Electroboom. Of course reading and learning math is helpful (see the The Manga Guide to Electricity :D ) I wish you luck on learning electronics!!>>79663

I have been wanting to get into it too. I feel like Raspberry Pis, Adruino etc are less satisfactory. I was thinking of doing circuit bending just to practice soldering. That is something you can get into low cost and without any prior knowledge. >>79705 You can fix modern PCBs, it just id a different skill because you need either a hot air solder gun or a soldering hot pad as well as tweezers and a lot of practice and some luck
