Notes on Electronics Design

As I've said before I'm a complete novice when it comes to electronics and circuitboards. The classes felt like I was sitting in on a foreign language meeting and not understanding one bit of it. When we eventually started out building the board the in Eagle software it wasn't long before I was completely lost. I had to ask my fellow students and my guru multiple times what the heck I was doing wrong now! Eventually I got the hang of it and my first PCB design was just a copy of Neil's original board... With an added Batman logo, which I added in photoshop... Don't hate me!
Here is my carbon copy of the Hello-world PCB. As you might be able to see I connected the pins with lines but also with coded lines (ie not visually connected)

I added the batman logo for some fun but I ended up discarding it again in favor for more LED's!

I ended up adding three LEDs on my board. Two are connected to the same pin while the third one is connected to a seperate pin. I'll have to think of a good reason to have the LEDs light up seperately from each other. It was a pain to route the connections under each other and with enough tolerance for the Modela to be able to still mill the traces. Eventually I got it and I added some round corners too. These are the .png that went to the modela:


Milling the board was easy having done this before a couple of weeks ago.





Soldering on the LEDs was a little tricky. We had to discover on our own that the green line on the LEDs needs to go toward the cathode. After the board was soldered together I used a multimeter to see if the LEDs worked properly and if I didn't have any shorts in the board. All was done well. Now to program the shit out of this puppy!
