I'm a newbie when it comes to hardware design. I have a little bit of exper=
ience with PCB design and made a couple of small circuits for learning purp=
oses. I need to test out this new PCB...

Have to design a boost converter that creates around 150V from 20V,
north of 100 watts. Since this can cause grief with core losses it has
to run continuous mode. So I need a diode with no...
for the next day or so www.thecubenet.com is offering a 25GB block account

I asked Coilcraft if they had any high-voltage inductors and they said that they
don't rate their inductors for voltage breakdown. I was hoping to string
together a few surface-mount parts.
I might design a box that has a 5000 volt power supply inside. I was thinking
that I could have a warning LED (or two independent ones, for redundancy) that
indicate that HV is present. It could...

I'm learning the fourier transform but I'm confused by a problem.
As an exercise, I've created a Python program to model the effect of a
low pass RC filter on a digital waveform. The prog creates...
With the Little Box Challenge, Google (and IEEE, and a few other
sponsors like Cree and Rohm) is offering a $1 million prize to the
team which can "design and build a kW-scale power inverter wi...
This was suggested by part of Jim's "VoltageIndicator_NoHang.pdf" circuit.
Cute, possibly even useful somewhere.

remove the batteries (they are heavy and a PITA to keep
"up to snuff" for VERY long periods of time). So, I'm
