any other electrical engineers here? working on shrinking my final project for my intro course.

This is /g/ - circlejerk, shills and consumerism.

In all of its shitty glory
I'll get an MSP430 launchpad and a bunch of ESP8266 to play with during the Christmas holidays.
I did some EE back in school. Sup?
>>51620626
>>>/diy/ would be better for EE prototyping

what you making OP
>>51620596
What does it do?
>>51620596
Deadbug it
>>51621287
>>51621299
it's a combination lock based on two CD4013 ICs, basically you trip 4 flip flops in a row and it activates the lil relay coil. diagram that I found for it is actually wrong, missing grounding pin 8 on IC1
>>51621398
huh?
make your own circuitboard or custom order one online.
>>51621454
>>51621739
hehe that's pretty funny. I would but there's too many components.
>>51621454
So why would something like this be useful? I'm not bagging on you, I just know the absolute minimum on electronics.
>>51621880
There's never too many components for deadbugging

>>51621902
it's for OP's learning process
>>51620596
>working on shrinking
you have some empty space but not much. I suppose the buttons are on another board.
Since you can't get smaller components and you dont want to do this >>51621739
the only option left is to make your own printed board.
It's not that hard but you need a very fine drill for the holes and a very thin permanent marker. It won't shrink that much but if you don't fuck your shit you'll get extra points and it'll look cool.

oh, this 4x6cm board is my final board, it was previously on a huge breadboard, nicely spread out.
>>51623156
Breadboard->perfboard->pcb
OP, now that making pcb is waaaay cheaper than it used to be, do yourself a favor and download eaglecad or some other free-for-small-pcb software and learn how to do schematic capture and pcb layout. There are many options for pcb manufacture, but for something like this I doubt you could beat oshpark for a 2-layer design. Remember that their pricing is based purely on sq/inches, so concentrate on making it as small as possible. Keep on progressing with it. It can be a lot of fun and profit.
>>51620596
Make a PCB and order it through OSHPark or the like, and use SMT components.
Otherwise that's pretty small already for perfboard.

kek, you are a huge asshole
EECS master race here... Just burned my finger last week touching a burning hot MOSFET that I was testing out. Fail stories here, preferably green text.
>>51627067
I'll go first myself:
> Be EECS major
> Got that new Hall effect sensor that I ordered for my project
> Test it out
> Why the fuck isnt it outputting 2.5v for no field.
> Look at the datasheet again
> I wired the DIP version by referencing the pin numbers on the SMD diagram.
> flip output and ground.
> everything works
> happy

10x10 cm boards are actually pretty cheap if you can deal with the delay for shipping, for 5x5cm it's even cheaper. I did some stuff with very fine smt chips and they were able to do 6mil tolerances. 10 boards of a 10x10cm came out to like 20 bucks for the cheapest shipping

This was at an internship, but we had a defective board with a broken dram module that actually gave me a blister when I touched it, I looked at it under an IR cam and it was like 300C. Always look at the output current on the power supply, would be the lesson I guess>>51627067
>>51620596
I used perfboard for the first time yesterday. Just something to consider OP if you're soldering skills aren't great, or if you have really shaky hands like I do, you may save yourself some trouble by leaving your components a little more spaced out. It's easy to spill over from one pad to the next.
You can save some space by using a stripboard if you plan it out right
>>51621454
I had a similar project for my logic class, we had a vending machine simulator using state tables. pretty fun desu

My boy you going to Purdue? I've never heard of a school with ECE but Purdue.
Accidentally brushed one of my psoc 4 pins to ground. Blew up instantly. Damn it.
CPLD programming a fun though
>>51626808
Use D latches, problem solved.

REMINDER: MEs learn how to ME, EE and CE.
EEs can be the Wizards of Engineering but MEs are the Gods.

Done
Just started playing with this seriously. Trying to find a good breadboard kit that'll keep me busy for a while. In the meantime I just keep building my projects in kicad.
