What a incredible thing!
Even though I'm from Korea, I have learned English for 8 months and I don't understand all what you talked, I'm just interested in.

What does it use for? Can you control on Linux based?
I'm just wondering....

It is first time to write comments. ^^
I'm looking forward to receiving your answer.

Have a nice day... -+- 24.67.253.203 = Mozilla/4.0 (compatible; MSIE 6.0; Windows 98) 2002-11-06 -+- Harinder -+- dhingra_h@yahoo.com -+- Great.

I have built 2 standard ones before. But your Schematic is the best!
Thanks ! -+- 80.133.214.179 = unknown_agent 2003-05-28 -+- qujinpeng -+- qujinpeng@sina.com -+- Great!
I think the project is very perfect!
The Explaination is very detailed!Thanks! -+- 218.79.60.98 = Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) #2003-05-28 -+- ahxian -+- -+-
I think many people would glad to see that if u can provide a Protel .sch document ,althoug protel is not freee.

I'm a total Newbie in microcontrollers and couldn't find the answer to my question in the datasheet, so I hope you can give me a little help. Is it possible to switch the push-buttons-lines by using optokopplers? Is the voltage between common_button_lines and push_buttons high enough for that?

Thanks in advance

Thomas

voltage levels are basically TTL compatible. You can use "optokopplers" -+- 217.185.243.142 = Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6 2003-10-15 -+- Christian -+- <c.kirschenlohr(at)gmx.de> -+- What about the costs of this Power supply? What are the totla costs for all parts in €? If its not so expensive, it could be a nice thing for electronic students...

Thanks
