An Ultra Low Wattage, High Gain Tube Amplifier
Hi, I'm building your Artnetreceiver at the moment but I'm not sure about the MAX485 pinout. On your schematics it looks like you've inverted the RE-pin. How did you do that? And why not just connecting it to ground?

Thanks, but I had to make the bigger one for cutting smaller cicrles ;)
You're welcome ;)
As I just uses some wood I found in my storage, it's indeed a bit heavy.If I would buy some wood for another one, it would be way lighter!Maybe I'll make a light-weight-version one day ;)
I wonder if your circuit will have problems with two 1 Farad Powercap (car hifi caps).Your instruction reads like you're using the inner resistance of the battery to limit the current. As the powercaps are capacitors, current might be higher?How can I calculate my currents in this case?And why are you using the MCP1407 instead of just a current limiting resistor between µC and FETs or just another small capacitor like BUZ11?
