content: Quote from: sleemanj on May 31, 2014, 09:01:31 ami have lotof parts. i get 60x80x40 box. full of electromic komponents. smd components, microchips and many moor parts. sou, for me cheaper build may self. i have all what i need, just need spend may time, but i have lotof time.

content: actually no-one can build an arduino cheaper than the chinese clones. of course you can build one to have some fun while building it, but otherwise it's impractical (mainly economically). over here the atmegas are sold for something like 4-6Euro when buying single piece quantities, at the same time you can buy arduino nano Chinese clone for under 7euros from dealextreme. the nano is ideal for using in projects - the whole board fit's into a DIP 40 socket cut down to 30 pins (ok you might buy a wide 32 DIP socket , but those are kind of rare).

content: only problem find pcb board files and schematic. i thinc, i dont know hou to corectly use internet resurses.its be good, if samone can send to the me all files what need and build ideas.i eill like tray build many prijects.

content: arduino is open source hardware - the schematics and the board layouts are all over the internet - just use google.

content: If you can't even figure out how to use google, your chances of doing anything useful with all those parts are pretty low.Instead of posting repeatedly asking for others to do everything for you, why not take a moment to learn how to search for things, and when you ask for help with something you built, don't just post "doesn't work" and expect others to fix things for you. Put a bit of effort into explaining what exactly you have done, what doesn't work, and include links to whatever source files you based your project on. We're not telepathic and unlike you, we don't all have lots of time free.

content: Quote from: Aigars on May 31, 2014, 10:47:47 amI already posted the schematic of the Pro-Mini above, that is the simplest Arduino you can have (well, unless you drop the crystal as well and run at 8MHz).Here it is again:http://arduino.cc/en/uploads/Main/Arduino-Pro-Mini-schematic.pdfUnless your box of parts happens to contain an ATMega microcontroller, then you don't have all the parts you need to make an Arduino - the ATMega is the only part that actually has any meaningful cost.
