Thanks for that link, I really had no idea dual power was a requirement for anything, ever. This all must be done internally in the TR-808 or TR-909s. I am glad you sent me that page, because I was...

Yah, I couldn't get them to move either on a test file. I have used this process before and I'm sure it worked as advertised. It seems straight forward, you would think. Maybe Vanepp or one of the...

I had that problem before, but I can't remember what I did. Maybe close it and reopen it. You can upload the .fzz here with the 7th button and I can have a look at it.

Can't seem to bring LEDs to front
A work around in case there isn't a solution, would be to move the leds up 3 holes so the body of the led overlaps the IC and the wires are then below the body. That then obstructs the pins of the...

Program dies when I try to do a file open
The only thing I can think of to suggest is (if you are willing!) try running Friting as administrator. This sounds to me like a permission problem somewhere (combined with a Fritzing bug where it...

On an unrelated note, you likely want current limiting resistors (likely about 220 ohms) in series with the leds. As long as you use 74ls173s you may get away with it as is as there is a 100 ohm...

I think VAN is right about wires in BB view always being in front, i.e. so that you can always see the connector hole. I think I vaguely remember a part on the other side of the PCB in PCB view not...

In modular synths the power supply will be fixed to the case and shared between all the modules via a distribution bus. There's no point making a seperate power supply for each module.The 808 is MAINS...

Hey thank you Noodle, Peter, Oldgrey. I tinkered a while with this circuit using the 9V batteries in series and an Arduino to provide a trigger from pin 13 so I can see the LED flash when it triggers....

Um, not really (unless you have uploaded the incorrect file). Your part is an 8 pin dip where the real device is 16pin, and the schematic is for a attiny13 not the instrumentation amp (even if it only...

j303: I noticed the batteries got very hot rather quickly and lost charge fast. I don't think that should be happening. If you have a multimeter or amp meter measure the current the circuit is taking....
