I hope this is in the right area to be posted. I m trying to find drawings that would help me in making my own Atmega board. Not that i can't afford to order a factory made one only building something and watching it work is a big rush. I would like to find drawing of one of the newer versions and one that would work.

Thanks

talk to ctech he might b able to help you
tell him the little monkey sent you ;)

Don't bother, go rebuild your piper cub for the next 900 or so hrs of your life, just watch free tv with plastic in between. It becomes more appearant every day that all the gadgets do is cost money, you still waste the time learning to use each one, the uptime really dosen't vary that much.... Stick with what you have, it works.

we woulden't have what works if no one b/4 us tested this stuff
not shooting you down but......why not incourage positive thinking

just my opinion
i do respect yours ;)

Loserbaby1, you may be correct in assuming the worst to come out of ones project like that, but I for one loves messing with electronic gismos. You know the ones that nornally quit working as soon as you let the smoke out. :huh: But want the heck. That is what it is all about the learning of mistakes. I have a collection of ole stuff that i must have spent a good bit of time and of coarse money but i look back at them and can appriciate the experience gained from them. Any way still looking for those drawings. If anyone has and doesn't want to post them please msg me.

Thanks

pipercub

mas sent me down the path of knowledge
did a search on atmega schematic and shazam!!!!!
way over my head!
thought it might be like putting some leggos together
i dont have the skill as of yet or the time to build my own
but it was still a good learning experience
i reccomend you too do a google and look into it
it sounds as if you are at the skill level needed to procede.
good luck

thanks mas

Constructing your own equipment can be a fun and learning experience. But there are some pieces of electronic equipment that it is better to shy away from building. You can purchase the materials to build an Atmega board from scratch at most electronic parts supplier stores. But I would not do that. Building the circuit board from scratch is a project for someone with a lot more experience in these things than most people have.

The circuit board will come in a size that is too large for your use. You will have to cut it down to the size you need. A table saw with a really fine toothed plywood blade works pretty decent.

You will need to "draw" on the circuit board the layout of where the copper foil traces will go. Then you need to get the "contacts" in the exact spot so that when th ecard is slid into the receiver it will match up to the receiver's "contacts". Once you get the board all layed out, you put the board into the acid to dissolve the copper where you don't want it to be. Then you have to drill tiny holes into the board in order to mount the components.

Then you need to go out and purchase all the parts you need and install them on the board. Then you program the card and if you everyting properly, it should work just fine. If you didn't well, back to the old drawing board.

A better idea is to purchase the board and the compnents as a kit. That way the difficult work is all done, and all you need to do is to put it together. It is much easier and the odds are that it will work when you are done because the kit was designed and manufactured by people who know how to do it. It will be the same circuit board and the same components you would get if you were to buy it all together. The only difference is that it won't be built, you need to do that.

There are a lot of things you can build on your own, and there are a lot of things that are better left to people who do that for a living. I think this is one of them. Still, if that is what you to do, then I say, "Go for it". Worse case scenario is that it won't work when you are done. All you are really out is the time and the money it took to try to build it.

Now, after having said all that, and keep in mind this is only my opinion, I will tell you this. Do whatever you want to do, and build whatever you want to build. Don't let anybody try to talk you out of building something you really want to make. As far as I am concerned, if you enjoy doing it, then you are a winner whether it works or not.

Best of luck in your endeavours. If you decide to build it, please let us know how it turns out.

After a few day searched, here are the schematic I found for the atmega, it might not the one you looking for

Bob, thanks for the sugguestions on the project. T must say that this is not my first rodeo. :) I have eteched many boards and never had to use a radial saw or even a table saw. eteching is really easy once you have done a few. I find that just a plain old razor knife will do a pretty good job on the cutting it to size. Just score it a little and it will break in that area. The placeing of the pads aren't too bad as i use a laser printer to do the art work for me. Then just dip in the etcant solution for a while and wash off and then you can start drilling. Placing the componiets and solder. Not too bad. But thanks any way for the info on that Bob. Thanks for the zips on the schmatic but only one seems to be a valid jpg :sad:

Thanks

I have used a razor knife too, and it works reasonably well. But then I tried my table saw and ever since I have been sold on that method of doing it. If you happen to know someone who has a table saw, try it sometime with an old circuit board. You need a really sharp plywood blade, but it will cut that circuit board so smooth you will think it was store bought.

Mas, thanks for the two files you posted. May be sometin i can use in there. The avr to atmega 128 file was a bit hard to open but got it going. Not sure what that board was meant for but i guess i will have to figure it out. Bob, yes i plan on trying your method of cutting. I have a good band saw aswell. :) I would like to have more info on the boards and maybe some good closeup shots of it.

Thanks
Pipercub

I never tried to use a bandsaw to cut a circuit board. Maybe a metal cutting bandsaw would work really well, that type of band has very fine teeth and that is what you want to cut a circuit board. I have no idea how a regular wood cutting bandsaw would work. It may work okay, hard to say, but I would first try to cut an old junk circuit board before I tried doing it on a new one.

Getting all the plans together to build your atmega is the hard part. Building it is simpler than you think, there's really nothing complicated about it. Although they are very cheap priced nowadays, and we have tons of SOLID, Dependable, Reputable Dealers here at DSSTESTER. Try keeping it inhouse if you'd like, we're all a tightly knit Family!
