www.comfiletech.com ad in Nov. 2005 Circuit Cellar
Family of mega128-based goodies, low-end being the CB220..

Interesting - looks like $34@1ea gets you a 24 pin DIP carrier with a mega128 on board, along with 5V regulator and an RS232 driver.

It comes with an in-Flash bytecode interpreter for a flavor of BASIC which seems way better than BASCOM and an industrial controls world interpreter for ladder logic. The compiler seems to be a free download.

Of course, you could connect a programmer to the MOSI, etc pins and overwrite this with whatever you wish.

Just seems like a very low price.
Several other packaged products too.

I just bought this one at Propox (Poland)

http://www.propox.com/products/t...

For $40 you get M128 + Complete Ethernet + 64/128K-Ram

For $1 more you get a 4Mb dataflash also

Both of these are nice, but neither of them seems to give full access to all the pins.

Of course this is hard to do while still using a "PDIP" form factor.

These sites are offering pretty impressive products.

Have any of you guys ever seen such a board featuring "semi pro grade" audio ADC/DAC? (16 bit/ 44.1 kHz...) I would really like to have one of those.

We are looking at an app right now where it may be advantageous to incorporate an audio codec. My personal conclusion is that AVRs are not suited to support the streaming I2S port without glitching especially on "record". I'm planning to try an ARM AT91SAM7S that has I2S support plus DMA.

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

Oh, that's sad to hear about the AVR :(

I take it that you would layout and build the board yourselves?
