AVRISP2 is the safe and good way to go. USBASP's of the first generation had a jumper to slow down the clock. Current version detects the max ISP clock automatically, so should work, but never tested...

Why not give it a try ? The compiler will tell you if he doesn't agree ;) FYI: Mark released 2.0.7.7 beta recently.

I'll agree with others here. Your traces are too narrow, especially on power and GND. Copper is good, copper pour your boards, allow floating pours if not much copper is left on the net grounded pour....

You need to isolate the triacs from the logic as they produce switching spikes from the back EMF of the solenoid valve so using an optocoupler like the MOC3081 triac driver for each triac and having a...

Yes I have tried my RS232 (STK500 type) wit 1mhz AVR clock so that means 1,000,000 / 4 = 250,000 SPI and it works fine. What is the lowest CPU clock you are running? Regards Paul

The transformer with 12v 0v 12v 0v is very common but just as common is this type http://www.jaycar.com.au/productView.asp?ID=MM2008 This one would give a 6 volt winding for the logic the diagram...

I am curious why you run at such low clocks I have found no reason thus far in my many projects to do so but always willing to learn even though its just my hobby. Regards Paul

The most important reason to lower the clock is the power consumption. When lowering the clock it's also possible to lower the supply voltage. If you make a battery supply device low power consumption...
