Atmega128 development board

[mathman47]

What layout software did you use? I just received my atmega 128 board and am trying to learn all I can at age 62.

hey dude, that's cool. I like your videos.

[mileyrocks929]

Great I love your vids!!! Lol

[linuxgeek81]

Thank you.

Nice board.

Why do you use type A usb jacks for all your projects and not the standard type B ones for slave devices?

[linuxgeek81]

Thanks. No specific reason ;)

Hi,

Impressive work! What DAC you're using on the board?

[linuxgeek81]

I'm using an DAC0800, not the best choice obviously, but the only one I had in stock ;)

The PCB quality and the clean layout are impressive, the board looks very professional.

Off topic

I don't know how you can do a 2 layer PCB without mistakes an so precise at home, especially this big board.

I need to do PCBs with a few SSOP parts, but I'd rather have it factory made. Using the photo method i got either many cracked or shorted traces.

[linuxgeek81]

Thanks. I guess I got my bag of tricks. In the end it takes a little experience. Actually I required only a single shot to get the board right - sometimes I get lucky ;)

Congratulations! It looks complicated. I assume by seeing the schematic that it's a modular design. How much time did you spend on it?

[linuxgeek81]

Thanks. I suppose I spent about 5h on the schematic and about 10-15h on the layout (did it manually). It took me another 5h to etch and populate the board.

By the way, 128 is great but expensive :( I only have one and it is overkill for what I need.

Really nice board!

[linuxgeek81]

Thanks, Odin. Not sure why YT only offers this rotten quality, though :(

[djodin]

i think the quality is good enough if you watch it in hq. btw, wich dac is that? dac0808? and what ic is the one over the atmega and the sram?

[linuxgeek81]

I cannot post URLs here... I'll write you a message.

[StutteringMatt]

I guess you would need some electronics equipment and some basic knowledge in that area aswell

i have a question

im 14 years old

if i get in a programing class can i do things like that?

sorry for my bad english

[linuxgeek81]

What are "things like that"?

[luis61961944]

i hope you undertand spanish :/

quiero hacer mis propios programas jugar con las tarjetas aser mis propias cosas me entendes?

i estoy buscnado clases de eso en mexico pero noc si hay asi como q una rama especial para eso

sabes como se llama?

[HLSDK]

He wants to make programs that use "cards", and goes to school in mexico. I guess they don't offer programming or tech classes that teach what you do.

BTW, that board is totally full-featured. I'd thought of laying one out myself but I am no good at routing. Do you use eagle?

2 layers makes it so much easier. I don't know how you can stand fabbing boards by yourself. I'd just send them out to be made.

Also: youtube "Analog computer bouncing ball"

[linuxgeek81]

I don't speak spanish, sorry.

Well it's fun to make something totally yourself. It's a hobby, so no serious stuff attached to it ;)
