Blocked or damaged atmega8?
It sounds like you might have inadvertently set a fuse bit of some sort on it. You may be able to hook up a parallel programmer to it to get it back. But usually it is easier to...

STEPPING MOTOR NOT STRONG ENOUGH
You'll need to really drive that sucker. 5v and TTL at 20ma won't hack it. I have used the EDE1200 and EDE1204 drivers like found at http://www.jameco.com/webapp/wcs... and http...

Switching a FET with an AVR?
I typically use either a Microchip TC4427 or a IR2117 driver myself. They work great. Or use the IR2214 if I am driving H-bridges.

Power MOSFET drive?
I have been using some of the Zetex H-bridge bipolar transistor arrays to good effect for 3v motor controllers. I know this works at 3v as I have been using it for that purpose to...

Compilers and Software
I'd check out www.8052.com like mentioned above, and I would use www.mcselec.com and get a copy of their 8052 Basic compiler. It only costs $69.00 and does everything you would...

We use the Olimex Jtag ICE programmers a lot. It works pretty good. Under AvrStudio 4.09 it upgraded the firmware as expected (with the as expected verify error). But when someone...

[OT] HONEYWELL! Getting cold, need data for MC68HRC705J1AC
A One Time Programmable ROM version is always a custom OEM part from anyone. Fortunately, it is a 1,024 byte ROM MCU, so making an adapter and using a Atmel AVR MCU like a...

vs1001 mp3 decoder SNR
Basically, MP3 is a "lossy" system for audio compression, but for the most part it tends to playback OK without noticeable audio quality losses. http://inventors.about.com/od/...

Is it possible to kill a Atmega162V using the fuses?
Well, my mistake, I actually meant to say that at first it recognized the MCU, but after I inadvertent programmed the fuses before I set the clock fuse setting, the chip went away...

i'm asking stubid questions ...
You could go and check out the Atmega8 Megabitty boards at www.junun.org. These a extra small boards for nano and micro sumo robots, but they can work on a lot of other things too.
