through-hole resistors and neodymium magnets


October 2, 2014, 1:04 am

Would a 1/4 x 1/16 neodymium disc magnet placed adjacent to a pack of 1/4 watt through-hole resistors in storage harm them in any way? I don't think so, but I figure it's a question worth asking. I'... Read more »

Modulating DC Level Relative to Fixed Voltage

  [ 2 ]
September 29, 2014, 8:49 pm

Is there a way to modulate the DC level of a signal while holding the peak voltage constant, as in looking flat on a CRO? IOW, as if the DC bias knob of a function generator was cranked up and dow... Read more »

Behavior transistor models?


September 29, 2014, 4:15 pm

Where can one get them, and is there a wide range of transistor type represented? How good are they, eg: E-B breakdown correct, beta at given sets of Ic VS temp correct?, Vbe VS temp and V... Read more »

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 ... Read more »
