How to restore fuses of my ATTiny85?
Did not see a "bypass capacitor"  in your pics.

ATmega reset pin protection diode
On older Arduino boards they did not use a diode.    With the way reset was performed by the FTDI chip using a cap between the DTR and reset of the AVR there were...

Using 74HC238 to run 5 Servos
OK let's do a little figuring here. With a 16,000,000 clock and a 8 prescaler the timer would be running at 2,000,000. 1/2,000,000 = .0000005 (unit of time per tick). .0015 (...

Using 74HC238 to run 5 Servos
Maybe use the timer in CTC mode and use the TOP value to define the current servo pulse width. Do a little math figuring what prescaler and TOP value will work to give good...

Help: Floppy Drive emulator with network connection
Having floppy drives on my HAAS cncs for programs I thought about this too. They do make them but the ones I found used USB. Some samples: http://compare.ebay.com/like/151... http...

pwm for servo
How are you powering the servos? If by the 5v from the STK500 then maybe you have found the "straw".

Noobie ATtiny44A PWM
Not a C guy but Quote: DDRA = 0xFF; //all porta pins are outputs does not do anything for Quote: I'm expecting to see a PWM signal on PB2

Milling CNC machine based on AVR
Have a look at "grbl" which can run on a 168 or a 328. There are some hex files already done also. You will have to look at the docs to see which pins are used for certain...

Need help with my hardware
As a test dump the 7805 for now and take the 5volt from the STK500.

problems programming atmega 168a [solved: reset]
Quote: /RESET goes to PIN5 of ISP and VCC, nothing more. Did not look at diagram just went with his statement.

problems programming atmega 168a [solved: reset]
If you have the RESET pin directly hooked up to VCC then that is your problem. Put a resistor in series 4k7 to 10k.

Need help with atmega168 and 16x2 LCD
If it works on your arduino (the UNO i'm guessing) why not turn the 168 into one of the arduinos that uses it as the processor so you can just use the sketch that works.
