Really impressive job!Molto bravo!

What a fantastic project, great job!

Realy impressive! Real nice job. Im sure a bit more CPU speed and ram would go a long way... I normaly use PIC18f series. 48mhz for dirt cheap + usb.

Any chance that you may sell kits of the "uzebox for photo frame"?

Nice results, have you considered dropping the AVR and moving up to the big boys, say an ARM core like the AT91SAM7S, 50+ MHz, 512K FLASH, 64K RAM, only costs $10 for the chip, free C/C++ compilers. It's real easy to get started with that, not as scary as it might sound :)

Hi,

Very interesting project you got there! If you're interested in a bit more power and space, we could work something out. I dev hardware so if you're interested, leave me a message.

I will always have a soft spot in my heart for Atmel 8 bit cpus and their role in introducing so many people to the delights of making things with microcontrollers. The Atmega644 in the current version of the microtouch makes little sense and is not high on the AVR price performance graph (much cheaper AVRs run the same demo). There is no practical reason not to use an ARM but I do love the 8 bit beasties so.

To say this is impressive is a huge underestimation. Dude, you'are a wizard.

No kits but I can send you a pcb if you promise to use it ;)

I think this is an amazing project. You should seriously consider making a kit out of this.

Thanks,

Hello

Very nice project, I like it a lot :)

congratulations

massimo

That's absolutely impressive!
Congratulations and thanks for sharing :).

A lot of people don't seem to get it. If he wanted to write this demo for an ARM processor, then he might as well have just written it for the iPhone in the first place. That way, he could've spent the next five years authoring the code and demo content, and nobody would have noticed.

What was the total cost of the build? How much if you were two build a second one?

Wow, this project is AWESOME! Thanks very much for sharing! Any cheap source for that same LCD? I've always wanted to make a picture frame using simple AVR (instead of a little arm board running linux)

The screen is ~$10 in China, CPU ~$7.50, Lipo is ~$5, 2 layer PCB is homemade ($2.50 in production), < $5 for everything else. So call it a $30 BOM in small volumes. I gutted dead Sylvania SMPK8854B mp3 players. The B is important; not all Sylvania players have the right LCD.

cool but who is the music in the background?

Camper Van Beethoven covering Pictures of Matchstick Men ... good eh?

Id be interested in buying a kit.

You are my hero!!

Hi rossum, This is an excellent work, I would like to implement one, but there is little information regarding components, please could publish the list of materials (BOM)

Very nice demo.
Have you considered trying to use an AVR32 device instead of ARM? Don't know how they compare on price, but I think the AVR32 should give you more CPU power.

I want to know what the name of the compiler that you used for your application?

I used WinAVR. 

Hi, andd WOW! very interesting use of Atmega processor, Can you please provide me with a PCB(in your post you offered pcb to another person) aswell as a parts list. thanks,

Any chance of making a kit and selling?

I will be making a kit of the 2.0 version; in the meantime send your address to rossumur@gmail.com and I will send you a PCB for 1v1 if you promise to use it ;-).

impressive!

I would buy a kit in a HEARTBEAT.

You did a great project. It's very impressive. Congratulations.

Really awesome work.....
I tried to do implement this one from the repository given. But have some issues with it, Can you clarify those?

I found an LCD supplier. Unfortunately shipping to the US will cost $25.

http://www.thaieasyelec.net/index.php/display-module/tft-with-tp/2-8-inch-qvga-tft-lcd-with-touch-screen/p_8.html

Cheapest and easiest place to get the screen is to search ebay for SYLVANIA SMPK8854B, a touch mp3 player that commonly shows up as is. I have bought them for $1 to $10 + shipping. Just make sure the LCD isn't cracked. You also get a LiPo cell, connectors etc. For example, right now there are 9 with zero bids at $1 + $13 shipping that will expire in the next 24 hours. I have seen them in China for as little as $8 but shipping and translation makes getting them a little tricky.

wow that is much cheaper. So you title the post as "AVR homebrew device with iPhone aspirations" have you ever thought about adding a cellular module such as the GM862 from Telit to make give it cellular communications?

I've been working for some time on a custom cell phone design. Until I saw the capability of your system I was planning on a system based on Android and a high end processor. Now i'm thinking about a smaller processor maybe a little more powerful then yours to do the job.

Also, what can we expect in 2.0?

2.0 is smaller, faster and cheaper with a few more hardware features - probably January.

Sir i like u r project we want to do project on that but the layout diagram does not having any pin details to connect
plz mail me the details on that and also send me full schematic diagram.....sridhar.kurumindla@gmail.com

Very nice job ! I love it !
If you need more calculation power from Atmel CPUs, keeping your existing AVR tools, I recommend you to move to Atmel AVR32 UC3 devices. UC3B could be a perfect fit for your project.
