It looks like about 70 USD for 5 15x20cm boards which is fairly reasonable.
I probably won't need a board that size once I actually draw out the circuits properly.
I've been trying to get my head round Eagle CAD (Jim lent me a copy of the pro version). Takes some getting used to, but a few youtube videos definitely helped.
I'm going to give the laser transfer/etching method a go once I've finished designing the board. The board's not very complicated, just a bunch of floppy drive sockets routed to a pin header to make my floppy organ (it's cold outside, John) a bit more organised and less prone to random braking.
I think if I design mine well and I don't just have the screw connectors down one side, instead having them spread across 2 or 3 sides I could probably get it down to 10cm x 10cm which is only $18.90 for 5. Assuming that leaves enough space for 20 to 24 transistors.
There we go, very simple test.
4 LEDs addressed from one shift register, 4 LEDs addressed from the other.
I wonder of that will work with the PWM frequency library.
Is it the power supply (if you're using it) that has fixed the flickering?
:) Can you make it play a song?
Nooo. Really no. Don't make me want to spend even more money designing my own PCBs as well. Yes, I'd love to. I've already spent too much. Lots of little spends adds up.
Do all 5/10/whatever boards need to be the same?
ShiftPWM allows you to choose the PWM frequency so the other library isn't needed.
It seems anything over "75" stops any flickering. I had it at 150.
I'll try 3 shift registers tomorrow.
Currently yes, but I'd have to hand code it and I think I'd go insane. Next job is improving the software. A lot.
I can wait til the software is better. Can you play the theme from Project X on the Amiga?
