Eagle Video Tutorials BLF Style

Um, you might have the brd layout only.

You can use mine:

C_0805: https://www.dropbox.com/s/vjp519alpdh3i11/C_0805.lbr

R_0603: https://www.dropbox.com/s/kpgrd56e0nyhvhh/R_0603.lbr

Just download and paste those into the eagle library directory. No need to run any scripts.

diode and all that good stuff? So far they are showing up…do you use 0603 or 0805 for your smaller builds…probably the 0603

Try this

Yeah I use all 0603 unless specified (higher power requirements etc)

Great videos you have make caused me thinking to up-date my EAGLE 5 to 6.

Dang…15mm is sooooo teeny tiny…running out of room to put the 7135 chips

How do you put components on the bottom?

I think I might have room for 5 chips if I can put the 4 7135’s on the bottom around the center positive contact

Use the mirror command. I talk about it in the tips and tricks video. I think.

There is a mirror switch in the tool bar. Left click the mirror switch and then left click the component. The component will turn blue to indicate that it was mirrored to the bottom layer. Now, you can put it to where as you wish in the bottom side. The icon is look like this [ l ].

15mm is not tiny! Try 10mm. :smiley:
Waiting for oshpark to send recent 10mm design I did.

When starting out it can be good to try for too much in a small board. Don’t want to get discouraged.

Ah got it…mirror the components you want on the bottom side, then only show bottom, bPlace, bOrigins, bNames and you can see the bottom only…learning a bit at a time

My one major complaint with Eagle is there appears to be no "quick switch" button. If I want to switch between working on the top or bottom layer excusively, I have to open up the layers panel and deselect/select all the layers I want. It sounds lazy but it's a pain. What would be nice is a function where you can definte your top and bottom layers you want to use, and then all you have to do is press a button or hot key and whammo...switched layers.

Alas it does not exist. I wonder if someone can write a script?

EDIT: looks like it's actually possible: http://dangerousprototypes.com/2012/07/25/how-to-eagle-shortcuts/

Might have to muck around with this at some point.

Delete layers you don’t use. :bigsmile:

Can't believe I never bothered looking this up, despite complaining about it every time I use Eagle...which is daily. I amaze myself sometimes haha.

IIRC you change your grid to mm when starting a new project. I always work in mm as well.

10 would be for multiple.

Anyone have any tips/howtos on vias…with my attempt at a 15mm 5*7135 (SK68 driver I hope) I need to figure out how to route the VDD and OUT traces (I am putting 4*7135 on the battery side and one on the ATtiny side [I might be able to squeeze one extra in…but it will be a VERY tight fit)

Honestly this is a bit overwhelming…but a teeny nibble at a time I am getting there… (maybe after a dozen or so years I can make it look easy like Mattaus and others do :smiley: )

What tips do you want? Vias are pretty simple to use once you know how they behave. Draw the first trace to where you want the vias to be (or close to it) and then switch the opposite side's trace and it automatically puts a via where you did the switch. I do exactly that in part 3B when I was connecting LED- pads together; the AMC chips were on top but the trace was underneath. Might be worth re-watching it ;)

Also, you may consider this cheating but here are my 15mm 7135 files:

This was for you but I can't remember what stage I got up to.

Stick with it. It gets easier the more things you try and do. Practice makes perfect and the best way to practice is to make things that YOU want.

Awesome…I will definitely check em out

Are these completed or do I take em and run with em?

Most excellent Matt…thanks!

hehe…I uploaded it to render it on OSHPark…mine looks almost identical to yours [my 7135’s weren’t as far into the ground ring as yours were] (at least I know I am on the right track when I make mine look a little like yours)

I’ll definitely take the ball and run with this one though!

As I said I can't remember what stage I got up to. You'll have to open them up and see whether or not I had finished tracing everything, labeling etc. If I remember I'll take a look tonight and confirm. Pretty sure they are not final though because if they were I would have put them on OSHPark for you.

They don’t have the ATtiny support hardware…I got that on mine…but i see what you did on your board, you pushed the 7135’s out a bit farther than I did on mine, and I see how you did the via thru from the top 7135 to the ring of chips on the bottom…I will take your design and just tweak it up (it’s alot more efficient than mine even though it came up at max size…looks like it didn’t have the cutoff ring)

I actually think I might be able to do this and make a board…wow…who woulda thunk it :stuck_out_tongue:
[of course the hand holding the entire way is what got me close enough to get there]

Once your done, send me the files and ill double check it for you if you like.

If I like…haha…I will be begging for your expert eye to make sure my first build ain’t a bust :smiley:

Heck just your video’s have educated me enough to get me on the path to finally being able to say I contributed “something” to the community
