Hi all,
We are wondering if a solution exist (among all major ic manufacturers)
to insure 10KV dielectric rigidity for digital transmission (1Mbits/s)
on a small PCB.
for 50K pces a year the smallest and the cheapest are the best ...

Clarify Frequency Multiplication
[ 2 3 ]May 18, 2012, 3:15 am
Linear mixing of two generated frequencies is the electronic
equivalent of mathematical "addition". This can be easily
demonstrated in function generator software.
What then is the software equivalent of "multiplying" two sine... Read more »

Photon counting (again)
May 17, 2012, 8:51 pm
I measured the 'photon' statistics on the reversed biased GaP led's as
photo detectors today.
I stuck an opa134 across the 100k ohm resistor to drive the 50 ohm
cable and counter. RC tau = 1.5 us. About 15pF of C. (3pF from
opa134 and maybe 1-2pF... Read more »
Interview with Colin Mitchell from Talking Electronics

Hi All
Long time no visit.
Just letting you know that I've finally got around to uploading the
first part of my interview with Colin Mitchell from Talking
Electronics magazine fame when I met up with him at his home in Sept
last year.
He was kind eno... Read more »

propagation velocity experiment
This would involve CK722 transistors, slotline samplers, and pecan
pralines [1]. Unit of measure would be kiloseconds.

Does anybody have a working LT Spice netlist for a simple schmitt
inverter/R-C oscillator? I tried one using the library schmitt
inverter and get obscure sim errors, and I don\'t understand the HELP
stuff.

Squegging in LC oscillators
I have been playing around with my homebrew VFO, a Hartley oscillator,
with a tapped inductor in the tank.
Rough parameters: 6AH6 pentode for the VFO, tank resonant at 1.8Mc,
plate circuit resonant at 3.6Mc. Rather low-Q plate tank (on purpose, I

STmicro acceleration/magnetic sensor LSM303DLH == LIS331DLH + HMC5834?
Just had a look at the LSM303DLH datasheet and had a déjà vu ;-)
It looks like ST has simply put a LIS331DLH and a HMC5843 into one
package. (The HMC lacks the built-in voltage regulator)
All data are nearly identical, even register and I²C addre... Read more »
