Hi Jorge,

 

I am a new user to Eagle and I am having a hard time with a schematic. I

had created some components which I recreated after I learned the hard

lesson of schematic view's limitation to 0.1" grid snapping

After implementing the new components and running ERC, all nets on one

IC still show "net N$ overlaps pin". What can I do to fix this?

Thanks in advance!

Hello,

I am working in a library trying to create a simple oval pad. When I switch the pad to oval it no longer shows up. How do I get this to show back up. Also is it possible to create a long pad like a oval pad but with flat caps?

Thanks,

Blake

Hi Sean,

We have a list of users we usually recommend when work like this comes

up. I personally can't get involved with the project, but send me an

e-mail to support@cadsoftusa.com and I'll forward the list to you.

Let me know if there's anything else I can do for you.

Best Regards,

Jorge Garcia

dear mr. garcia wow thats so exciting that you think one it's a good idea and two doable awesome the whole reason i even asked you the question is because of your love of l.e.d's i know they work very good and there are alot on the market but i would like to design my own light also but first the timer i also want them to have a remote in case you want to turn things on or off without exposing your plants to light during the flower period so where would you advise me to start i really only have around ten thousand to work with at the moment but computer engineering stuff i would have long learning curve to get the info i need to retain to do this kind of work so if you could give me some more advice if you would like to work on this with me or you know of someone that deserves to be a partner with me on this please let me know i do need help to bring this to market and thank you so much for your reply so happy to hear it

Hi Sean,

I hope you're doing well. You've mentioned that you lack the know how

and the equipment necessary to execute the ideas you've described. I do

think they're feasible and could be produced.

The tradeoff now becomes time vs money. Do you take the time to get the

know how and the equipment, to then spend the time developing the idea,

prototyping, debugging, etc. Or do you spend the money to higher someone

to take the idea to fruition. You're the one that has to make that decision.

If you're going to get the know how yourself, I'd recommend starting

with an Arduino it's probably the shortest path to a finished solution.

Learning about Safety is also important since you'll be dealing with

110V/220V AC. This would be a very basic start, but it's only the first

crumb.

hth,

Jorge Garcia

dear mr. garcia well sir i have an awesome idea but i don't have the know how nor the equipment to get it done so i would like to run my idea by you and see if it can even happen and get it written down sort of a digital patent to say it was my idea first i guess anyways here's the idea i want to build a better timer i want it to be about the size of a regular wall plug in multi-outlet and i want about 10 plug in's that can be controlled indipendtantly from the other's by inter facing with a computer i think the way i worded that is right so when the buyer gets his timer home he plugs the timer into his computer and he will enter the time and date he wants the timer to be at and then he will be able to chose from a database like list of time settings for each plug in the device and be able to set the time to come on or go off up to every minute of the day and be able to set it months in advance if they so choose so they can have different plugs come on at different times then the cord they use to interface with the laptop or home computer they plug it into a wall adapter to power the device so there is the beginnings of what i think will be the only timer people that are serious about there times like i am i also want to design my own l.e.d. lights to put on the market they will have built in timers of course and a life meter that tells the person how many hours that device has been used and make them 110 / 220 i also have a few other ideas about this but let's see if you even reply to my pourly written letter but if you do read and think i could get this thing going please let me know where to start and thank you very much and have an awesome life   seanmcevers@yahoo.com

Hi Noah,

The problem still stands, in order to know where to connect the various

USB-MINI pins; you need to know what pins of your micro are going to

handle USB communications. Since the ATMEGA103 doesn't have a USB

peripheral there's no easy way to define what needs to connect to what.

Perhaps you're using the connector just for power, if that's the case

you would connect pins 1 and 5 of the USB connector to the appropriate

rails.

To define those connections you would use the NET command on the

schematic and the ROUTE command on the board.

Dear: Jorge

I would like to say first of all thank you for responding to my message. Second of all that is not the problem. You said to me that...

 

Hi Noah,

 

The issue here is that this chip (ATMEGA128) doesn't have native USB

support built-in. If you wanted it to hook up to USB you would have to

use a USB-Serial chip which is what the original Arduino's used. If you

intend to use this processor and need USB connectivity you'll have to

use a USB-Serial chip like the ones made by FTDI and others.

Jorge Garcia

 

P.S This is not my area of expertise so if anyone has any corrections

feel free to post them.
