@therobomaker957 : you're right. I deleted my scribd account recently. I tought nobody watched these videos anymore. You can find the schematic here: dl.dropbox.com/u/14703014/programador_attiny85.pdf . The programming software I used was avrdude. This circuit is compatible with "Nightshade ALF-PgmAVR", available in avrdudes default configuration.
@mYOzZyKaT: can't tell for sure (I've never user an ATTiny25) but changes are it can. Probably all it takes is just some rearranging of the wires to match the chip's pinout.
@comac2k2 ok.. I am looking for a really simple way to program that ATtiny25 possibly with just a breadboard like you have made it. Is it USB connected or seriel?
@mYOzZyKaT: Actually... it's neither. Parallel port programmers are easier to build. The circuit you see uses a USB cable too (the black cable seen along both white and yellow boards), but it's just for power. Parallel ports can't provide enought power to light a few leds.
@comac2k2 So it is USB connected. Do you know where I could possibly find a diagram for a programmer that can handle the ATtiny25 chip. I guess you are using the AVRdude to flash the chip right?..
I saw you were from Barcelona. My sister lives there, or rather just north of the city.. have been there so many times.. Its a so great place to go partying and just to hang out in some of the small bars in the Gothic area..
@mYOzZyKaT : beware. Technically, you might say it's "usb connected", but all the data signals come from a parallel port cable. Unplugging the USB cable turns off the LEDs only. Everything else would still work.
The schematic for my programmer should work for the ATtiny25, I guess. You just have to make sure you connect the signals to the right pins for your chip (check the ATtiny25 data sheet). Youtube won't allow me to post the URL to the schematic, but you can find it by searching for "comac2k avr" at scribd.
@mYOzZyKaT As far as I know, ATtiny25, ATtiny45 and ATtiny85 mainly differ in their memory capabilities (2k,4k and 8k), but the pinouts look the same.
@jiangyuebing : You can have my schematic online at scribd. Search for comac2k avr at scribd site and you'll find them (youtube does not allow me to post the link). Comments are in spanish & catalan, thought. There are lots of schematics for AVR programmers online, anyway. Just make sure you match your schematic to the use your sofware make of the parallel port pins.
I get an error when trying to open: dl.dropbox.com/u/14703014/programador_attiny85.pdf

Ah, I see, for some reason in pasting that address it got garbled. Works now

I can't find the schematic on scribd...your name does not pop up. Also, what software are you using?

looks great... can this program a ATtiny25 MCU?

I used to live in Barcelona. Now I live in Rubi.

@comac2k2 I will have a look and try to breadboard it out... otherwise you simply have to spell it out for me like I was 12 and had only thumbs...LOL
