My latest project - DAC + headphone amp

[matjans]

in case of a groupbuy, you can sign me up for one or two boartds too

 

[PM650]

sign me up for a board as well

 

[chengtaw]

sign me up for One PCB

 

[Geek]

Great!

We have 8 now!

Getting closer

 

[Ryssen]

I think we should put a tread in the GB forum,as all might not read all forums,how about that?

I agree, I think this should be moved over to GB, I personally don't venture over to the Digital forum very often, the only reason I saw this was because it was on the main page. I think we may be able to get more potential buyers if we post there.

Thanks,

Josh

Can you start the thread there,you seems to be well organized.

Thanks guys, done!

To program the AVR microcontroller, you'll need an Atmel AVR ISP or Ponyprog programmer.

If I cannot program it my self,how???

 

[Geek]

Maybe Gmarsh (or someone) can provide programmed parts?

I can't program the thing either.

You should offer to gift a PCB or two to someone who can? I may be wrong, but if gmarsh provides the code, all that needs doing is flashing the code to the microcontroller. How hard can it be?

If I had one of the programmer units I'd offer to do it. It'd be fun to learn.

 

[Ryssen]

How hard can it be?

Write the instruktions to it and I will se if I can manage it.

You understand that you'll need around $100 of hardware to do it? That's from what I can tell at first glance.

Ok,so I´ll be glad if sommeone who has it can do it for me.

The programmer isn't that expensive. And you can keep it around for future adventures with microcontrollers.

There's a few ways you can go.

AVR ISP - From Digikey, $29 USD for the original RS232 model and $34 USD for the far-superior MKII model which connects via USB.
Ponyprog serial - http://www.lancos.com/prog.html - built using a few resistors/diodes/zeners and a transistor.
Ponyprog parallel - Schematic's there too. Requires a 74HC244, diode, resistor and a cap.

That's a little cheaper than the one I can get here (and it's assembled!), but is it ISP only? For one person to do all the flashing for everyone prior to assembly you'd need an extra module and the appropriate ZIF socket with the unit I'm looking at. That brings the cost up quite a bit.

Still, for $34 it'd be well worth having around.

 

[Ryssen]

For one person to do all the flashing for everyone

Thats what I like!

I also have AVR ISP programmer. I just happen to pick it up for future AVR Adventures
