High voltage, low current reference.
I'm assuming you don't just want to buy one? (ie HP 6186C) Are you worried about generating the 350V, or just about regulating the current?

altium vs eagle
I spent a ~3 years using Eagle, and then switched to Altium in late 2007. It took me about a day to decide that Eagle was a joke in comparison. But this was back in 2007. Back...

finger protection for soldering
Definitely stick with leaded solder. I sometimes wrap a couple fingers in Kapton tape when I'm going to be holding hot things. It's thin enough that you maintain good dexterity,...

Like a Lemo connnector (but cheaper)??
Can you be more specific? Would a simple pin header work, or is this going to get beat up on? Does it need to have a cap on it? Does it need to be waterproof? Both when mated and...

So, what _will_ a RC servo tolerate signalwise?
It is very dependent on the servo. I built a robot a while back using HS-81MG servos. 50Hz PWM worked well with it. If I cranked up the frequency torque and frequency response...

Designing to pass EMI testing requirements.
Be careful with any high speed signals that are leaving the PCB. For example, I had massive EMC issues due to a full speed USB connection (the PCB was a USB device). They were all...
