This thread is for discussion about electronics and other related topics.

Literature to get you started in the hobby of electronics:
Getting Started in Electronics Forrest Mims III
The Art of Electronics by Paul Horowitz and Winfield Hill

Is reading literature not something you enjoy doing? You can learn about electronics by watching many of electronics YouTube channels instead:
eevblog
mikeselectricstuff
w2aew
Mr Calrson's Lab
Kerry Wong
Marco Reps

Interested in creating a PCB?
Visit http://kicad-pcb.org/ install KiCad EDA software (GPL) and read "Getting Started" guide.

Interested in simulating digital or analog circuits?
Install SPICE simulation software (BSD) and proceed to study https://www.allaboutcircuits.com/textbook/reference/chpt-7/introduction-to-spice/
Once you become familiar with SPICE, install one of the many GUI front ends available to make working with large circuits easier.

Having problems with your circuit? Can't decide which oscilloscope to buy? Why is there smoke coming out of my voltage regulator?
Ask us those and other questions in this thread. We will try helping you solve your issue no matter how large it is.

Pic related is my AVR dev board I've made last weekend, as I got tired breadboarding microcontroller every time I wanted to experiment with it. How's my layout and soldering? On the bottom of the board I've added +5v and GND header rails for easy access.

I was actually working on a simple irrigation system which is quite literally a relay hooked up to a 9 volt battery that will open or close a valve using GPIO pins but it turns out the water pressure was too much for the valve... I'll post pictures once I get a new one in the mail.

hell yeah! noice!

If you end up building a lot of this stuff, check out Kynar, also known as wire-wrapping wire, as an alternative to solid-core copper for the longer point-to-point connections on boards like that. It's a solid core 30AWG, so a smaller gauge, but very strong. I find it easier to work with, though it does need a little stripping tool (cheap) and a pair of needle-nosed pliers to take a little bit of insulation off the ends without mangling it.
